Roofs That Last...And Last...And Last At one major Midwestern university a routine roof inspection turned up enough furniture to fill a classroom. The low lying building proved to be too much of a temptation for students By simply reversing conventional design and placing the living on the upper floors of a neighboring high-rise. However, insulation above the membrane rather than below, the cause maintenance required nothing more than a clean-up thanks of many life shortening roofing problems can be eliminated. to the PMR construction technique which allowed the roof to This unconventional arrangement of roofing material—roof survive the regular deck, roof membrane, LightGUARD® or HeavyGUARD® onslaught of debris. ballasted roof insulation panels—is commonly referred to as If up-front cost is the upside-down system, or Protected Membrane Roofing considered as part (PMR) system. of the lifetime cost of a roof...the cost In all areas of the building envelope, the moisture barrier of a PMR system is placed on the warm side of the insulation. With one measures up well exception—a conventional roof system. In a T. Clear against the cost of a PMR system the insulation is placed above the waterproof conventional system. membrane to protect it from the harsh rooftop environment.

A T. Clear PMR System is the perfect choice for environments with high humidity such as paper and textile mills. When warm air meets cool air, water vapor condenses. The temperature at which water vapor condenses is called the “dew point.” In conventional roof systems, the dew point is below the waterproof membrane. So when vapor condenses it is deposited into your insulation and spread throughout by capillary action, decreasing its insulating value. It can literally “rain” inside your building and deteriorate the roof deck over a period of time. In a T. Clear PMR, the dew point is raised above the waterproof membrane. So, water vapor isn’t allowed to condense inside your building.

Figure 3. Correct Termination Piece, Long-Edge Termination C. Placing Insulation Boards Across Slope Changes 01. Insulation units shall be cut to conform to slope changes on the deck and to prevent breakage of boards spanning across slope changes. 02. Additional securement must be added if tongue and groove or staggered joint array is compromised or if boards are cut to lay flat on adjacent planes. 03. Small cut pieces must not be used in the system where a full board or a larger piece can be used.

The direction in which the insulation boards are laid will affect how well the boards will conform to slope changes without being cut. Laying insulation boards over uneven portions of the roof deck may cause the concrete surface to crack. This Figure 4. Roof Plan of Paver Layout cracking alone will not adversely affect system or product performance but breakage exposing insulation may. Insulation boards must not bridge over uneven portions of the deck. That will cause the insulation units to break (a crack through the concrete and the insulation). In these cases during installation the boards must be cut and additional securement added. In certain cases an appropriate piece of cut insulation may be placed under the LG/HG PMR Insulation panels to even the deck.

D. Terminations 01. Panels must be a maximum of 1/2 in. from all terminations or penetrations. The insulation may be beveled to conform to the slope of cant strips. 02.

LIGHTGUARD®/HEAVYGUARD® Roofing On Coal Tar Roof Membranes

Necessity is the mother of invention. The protected membrane roof was invented because the coal tar was leaking through deck openings into a building and damaging product stored there. In 1952, John Best of The Dow Chemical Co. created the first experimental LIGHTGUARD® Roof when he placed Styrofoam® coated with mortar over the coal tar on the roof and stopped this drip of the coal tar. Twenty-one years later, the roof coated with Styrofoam was still performing like new.

Today, 56 years after John Best’s experiment, LIGHTGUARD still performs the same function of keeping coal tar from moving on the roof and leaking into the building or drains.

LIGHTGUARD can be placed directly over old or new coal tar membranes. A coal tar BUR membrane covered with LIGHTGUARD is one of the most trouble free systems available. Several older coal tar roofs had insulation up-grades by covering the roof with LIGHTGUARD in the late 70’s and are still performing today. Many new roofs were built with coal tar BUR and LIGHTGUARD top covering during the same era, that have had no problems. The coal tar BUR and LIGHTGUARD roof has been the only roof specification of several architects, because their customers have no problems with this roof.

Coal tar is a substitute for Type 3 asphalt in all of our BUR specifications. There are a few unique requirements for coal tar:

1. Coal Tar BUR. Slope is limited to ¼” per foot. 2. The membrane must be covered with a minimum 4mil polyethylene bond breaker sheet, and LIGHTGUARD should not be placed over recently re- saturated coal tar without these precautions. 3. If the existing insulation beneath the coal tar BUR membrane is greater that R- 10 have the T. Clear Tech department check the amount of insulation required over the membrane to achieve membrane temperature stabilization.

TECHNICAL NOTE 97.02 7/08

Loose Applied Membranes with Protected Membrane over Monolithic Concrete Decks

Building codes often require a specific slope. Some existing decks will require tapered insulation to achieve the code mandated slope or to overcome a negative drainage situation. A cost effective solution is to use a loose applied single-ply membrane with tapered insulation over the concrete deck.

When this solution is proposed, T. Clear Corp. will provide a 10-year Total Performance Warranty, if the system is installed by a T. Clear Authorized Contractor; and the following conditions are met:

1. The membrane is currently approved and is installed in accordance with T. Clear Corp. Specifications for EPDM or Thermoplastic membranes. 2. A peel and stick or other adhered asphalt-based vapor barrier,* with a thickness of 20 mil or greater, is bonded to the concrete deck prior to the application of the tapered or other insulation. (See T. Clear Specification C-MB-1-AD) 3. Total average insulation R-Value beneath the membrane is no more than 50% of the total R-Value of the system. (Note: for high humidity applications a specific analysis of the system is required to determine R-Values that bring the dew point above the membrane.) 4. All deck penetrations shall be sealed to prevent air infiltration. (See T. Clear Tech Note #20 for details)

Exceptions to No. 2 and No. 3 will be considered where there is limited vapor drive and/or mild climatic conditions. T. Clear Corp. does not approve dead level decks with loose applied membranes.

* Currently acceptable vapor barriers are W.R. Grace Ice & Water shield, Hyload PMVB, Tamko Moisture Guard, Malarkey Artic Seal, Jiffy Seal, any modified bitumen self- adhering membrane, any one/two-ply BUR vapor barrier. Check membrane manufacturer for compatibility.

Securement Details for HEAVYGUARD® Ballasted Roof Insulation Jobs

The increased weight of HEAVYGUARD® provides increased win stability. The securement requirements for HEAVYGUARD remain the same as LIGHTGUARD®. Therefore, always follow the current published strapping requirements for LIGHTGUARD.

This note will address differences that using HEAVYGUARD instead of LIGHTGUARD, will entail. The main differences in the two products are: 1) its finished thickness and 2) its increased board weight.

1) Consideration must be given to the increased thickness where clearance heights are critical. The finished product thicknesses are listed below. The use of HEAVYGUARD over the membrane surface may require that access doors will have different threshold heights than those normally designed for LIGHTGUARD.

2” HEAVYGUARD 1 ~ 3” finished 3” HEAVYGUARD 1 ~ 4” finished

The increased thickness of the latex modified concrete topping of the HEAVYGUARD changes the dimensions of our normal fasteners. Corrosion-resistant curling fasteners that lock beneath the concrete surface are the present fastener of choice. The TPR-2 fastener is acceptable for this application. The TPR Peel Rivet is available from SFS Stadler, 800-648-6032.

2) The dead-load/live-load issue is one of great importance whether in new construction or retrofit. T. Clear LIGHTGUARD weighs 4.5 psf and the HEAVYGUARD weighs approximately 11psf. This weight factor must be considered when in the design stage of construction.

Recover Systems: LIGHTGUARD® Recover Over Existing Mechanically Attached Single Ply Membranes

General Codes allow only two roofs. This system, therefore, is designed to go over an existing, mechanically attached system. Prior to construction, the roof shall be surveyed for moisture; all saturated* insulation shall be removed and replaced with the same type of insulation as in the original installation. The deck shall be surveyed by others and declared sound. Record of the moisture and deck survey shall be provided by the contractor of record.

Wood or Steel Decks The primary assumption with mechanically attached systems on wood and steel decks is that there is no air barrier under the membrane, but the membrane can be made into an air barrier.

The old, mechanically attached membrane will become the air barrier in the new system. Therefore, the existing membrane must be intact and reasonably watertight. Any existing splits and tears should be repaired with standard repair techniques for the existing membrane. If the existing membrane has shattered or is otherwise permeable, the system or the area of damage must be covered with minimum 6mil polyethylene sheet.

Over the existing or repaired system, mechanically attach a rigid insulation board to the structure deck. Minimum requirement is installation to the uplift requirements of Factory Mutual 1-60. Table 1 specifies the number of fasteners required. Figure 1 shows fastener placement. Fasteners must be corrosion resistant and exceed the minimum corrosion requirements of Factory Mutual. Table 2 shows approved recovery boards and insulations.

Note: Before specifying extruded polystyrene over steel deck, determine if a fire classified system exists below the existing membrane. Some classified systems include: minimum 0.5 inch gypsum board, 0.25 inch Dens Deck, 1.2 inch polyisocyanurate foam, 1 inch wood fiber, and 1 inch perlite.

The new membrane must be installed loose laid or fully adhered over the new rigid insulation. LIGHTGUARD® is installed over the membrane according to current T. Clear specifications for systems over loose laid membranes.

Concrete, Lightweight Concrete, Concrete T’s, or Poured Gypsum Decks The primary assumption is that the deck serves as an air barrier. Therefore, all perimeters and penetrations shall be made airtight, before proceeding with the re-cover.

After determining that all penetrations are airtight, proceed with installation of an approved insulation over the existing membrane system. The insulation shall not be mechanically fastened; it must be loose laid over the membranes.

Warranties Re-cover systems, installed according to T. Clear Specifications, are eligible for T. Clear’s Total Performance Warranty (10 year maximum).

* The insulation shall have greater than 80% of its original R-Value as defined by New Wetting Curves for Common Roof Insulation’s: Tobiasson et. al.; Published in Third International Symposium on Roofing Technology. Alternatively drying curves developed and provided to T. Clear Corp. at Notice of Award must show the insulation completely drying in less than two years.

The media necessary for the germination of ugly vegetation, with rotting of leaves and constant barrage of blowing grit on the roof surface, can be abundant in the cracks and crevices of the surface. The two herbicides that are recognized to control the unsightly vegetation on the surface are:

1) SURFLAN® is a pre-emergent herbicide (applied to seed) for the control of annual grass and broadleaf weeds that germinate from seed. The mixture to be sprayed should consist of a mixture of 1.5 – 2.0 ounces of herbicide per gallon of water. All instructions and cautions on the manufacturer’s label should be followed.

2) ROUNDUP® is a herbicide that is sprayed directly on the leaves. Spraying should be done in a manner to ensure uniform and complete coverage. Plants should not be sprayed so that the spray solution runs off. The mixture to be sprayed should consist of a mixture of 2.0 – 2.5 ounces of herbicide per gallon of water. All instructions and cautions on the manufacturer’s label should be followed.

Application suggestions are:

1) In the spring (April or May), Surflan should be applied to the areas where growth is expected. (i.e.: perimeter of roof, penetration, drains and valleys.) 2) In the summer (June or July), a Surflan / Roundup mix can be used in areas of growth. This mixture is a 1:1 mixture of the two herbicides diluted as described above. 3) In the fall (August or September), Roundup should be applied to plant leaves to kill residual growth.

If vegetation control has not been a part your roof maintenance program, the above regimen may have to be followed. Once growth has been observed to be under control, spring and fall treatment may be all that is necessary to uphold the appearance of your roof.

How Do I Get That LIGHTGUARD®/HEAVYGUARD® Replaced and Resecured Without All That Extra Strapping?

Damaged LIGHTGUARD or HEAVYGUARD boards exist in an area of the roof array. Using a sharp knife, remove a damaged board’s tongue along the four foot direction as illustrated below at “X”. Care must be taken so that the knife blade does not puncture the membrane. The damaged board can now be removed from the array using a pry tool.

The system array can now be disassembled in order to remove any other damaged LIGHTGUARD / HEAVYGUARD boards by lifting out the surrounding boards. The system can now be reassembled with undamaged units until there are three boards left to be replaced and the opening resembles the illustration below.

The final three good boards in the replacement array must have the tongues facing in this direction.

1 Two of the remaining boards (B & C) have their tongues removed and corresponding grooves inserted in the foam part of the LIGHTGUARD / HEAVYGUARD so that both the 4’ long edges are grooved on both sides. This can easily be done with a handheld hot knife containing a long blade bent to conform to our factory groove. Boards “B” & “C” should have a cross-sectional profile as shown below.

Boards “B” & “C” are placed into the system and the remaining hole for “A” will have grooves on both its 4’ long edges.

Two pieces of ¾” plumbing PVC pipe are cut 24” in length. These pieces of pipe are the replacements for the missing tongues in the system. The 24” pieces are slid in the holes formed by the removed tongue/fabricated groove openings of “B” & “C” above, as indicated by the illustration below.

2 Finally, board “A” is installed into the hole with the tongue in its normal position. Using a knife blade, the PVC pipes are slid 12” laterally forming a partial tongue that will prevent the system from coming apart. This securement replacement is to be used for replacement boards in the field of the roof and is not intended as a possible replacement for normal securement as described in Technical Data Sheet 4.4.

*Note: In perimeter replacements (within 20’ from an exterior wall), on applications having wind ranges in excess of 110 mph, or on applications having System 3 securement, consult T. Clear Technical support (800-544-7398) before using this technique.

TECHNICAL NOTE 97.1097.107.107.10 7/087/087/08

REPAIR OF DAMAGED CONCRETE SURFACE ON LIGHTGUARD® / HEAVYGUARD® ROOFING

LIGHTGUARD / HEAVYGUARD Protected Membrane Roof Systems will frequently develop micro cracks in the concrete surface during shipping and handling. These cracks are cosmetic only and do not affect the long-term performance of the roofing material. Most cracks are only visible during drying periods after a rain or snowfall. When the boards are totally dried, the cracks disappear. If, however, the boards are broken during installation, we recommend that they be replaced.

It is not unusual to encounter broken corners or edges of the concrete surface. Cracking and chipping are natural and cannot be entirely eliminated from cement products. The appropriate repair of chips should ensure the long life of the LIGHTGUARD / HEAVYGUARD Roof Insulation. These damaged areas should be repaired as soon as possible in order to protect the exposed Styrofoam brand plastic foam from degradation is due to prolonged exposure to sunlight. If the foam is not damaged, coat with an outdoor latex paint.

The broken or damaged area of the concrete may separate cleanly from the surface of the Styrofoam or it may break away, tearing the foam and causing a portion of the foam to be removed while still bonded to the broken piece of concrete. In either case, the broken piece should be replaced and/or the damaged area be repaired as soon as possible.

If the broken piece can be retrieved, the repair technique can be simply a matter of bonding the piece back into place using VULKEN 116 SEALANT, by Mameco International as the adhesive. This repair technique can be simply accomplished during most seasons of the year following manufacturer’s instructions.

Before bonding the broken piece back into place, clean both surfaces to be bonded and be sure that they are dry. The preferred method for adhesion application is by using a cartridge of VULKEM 116 SEALANT, extruding a ¼” bead around the perimeter of broken area, and immediately placing the broken piece into position using firm pressure to assure adhesive transfer and good fit. If the broken area is larger than a nominal 8” x 8”, then it is advisable to also extrude a bead of mastic in the center portion of the damaged area before replacing the broken piece.

1 The recommendation for repairing broken concrete areas when the broken piece cannot be found or is not usable is to use a latex modified mortar mix. The most popular and easily attainable admixture for concrete is Acryl* 60, produced by Standard Dry Wall Products. However, any good acrylic latex admixture having 20% used to dilute the latex. Use straight Acryl* 60 as purchased to mix the cement/sand mixture into a workable slurry for easy application. A recommended dry mix proportion is 3 parts of concrete sand (ASTM C-144) and 1 part of Type 1 Portland Cement ASTM C-150 (do not use air entrained cement). Place with a flat metal towel and float or texture finish with a wood float. Do not make repairs if temperatures are below 45°F for a minimum of 72 hours to ensure good initial curing. Cover and adequately protect repaired area if temperatures are expected to drop near freezing point within the first few days of repair.

TECHNICAL NOTE 98.11 7/087/087/08

STRESS RELIEVING OF LIGHTGUARD® / HEAVYGUARD® PANELS TO ACCOMMODATE SLIGHT IMPERFECTIONS IN THE MEMBRANE OR DECK

LIGHTGUARD / HEAVYGUARD panels are by nature a rigid walk-able surfaced membrane overlay board composed of a 2’ x 4’ extruded Styrofoam board with a 3/8” and 15/16” thick concrete top. On some applications, cracking has been observed as the board is asked to span humps in the deck substrate or thick seams of certain membranes and stay intact while traffic is applied to its surface. In reality, the concrete cracks and the foam contours itself around the imperfection without breaking. Over time, the crack collects dirt and becomes visible. The crack in the concrete does not pose a product integrity problem, only an aesthetic one.

The LIGHTGUARD and HEAVYGUARD panels are able to span imperfections of 1/8”x 1”. Larger areas may have to be corrected for by alleviating the foam side of the board using a rasp, wood-carving head for a small electric grinder, or hot knife. To accomplish this, the LIGHTGUARD board can be placed in position and imperfection etched into the foam bottom by applying slight foot pressure directly over the raised area. Remove the LIGHTGUARD board, and remove the etched area in the foam using the above described instruments. Replace the LIGHTGUARD board and check that the LIGHTGUARD is sitting flat. This procedure should allow the board to sit flat on the membrane surface and will help prevent cracking due to uneven deck/substrate.

Rasps can be purchased at auto-finishing or woodworking stores. These are manual instruments and come in assorted sized and shapes and are self cleaning by design. The wood-carving attachment for the small rotary grinder is available through EIFS dealers or through Demand Products (800-325-7540). Care must be taken with the grinder wood carving instrument as there is rapid removal of the foam surface and sharp blades. Appropriate hand and eye protection should be used.

Adhesives for use with STYROFOAM® brand plastic foam 11/07

The question regarding what adhesives should be used with STYROFOAM in any given application is a question that is often asked by customers, architects, and suppliers. It is a question that must be addressed from many points of view.

T Clear Corporation recognizes that there is a vast array of high quality adhesives suitable for use with expanded polystyrene foam. Many of these adhesives are formulated to perform as a general purpose adhesive in many different applications with a variety of substrates. Others are for very specialized purposes. It is our belief at T Clear that the ability to make a recommendation for one of these adhesives over the other would require more information than is reasonably available to us. The continuous performance quality of an adhesive is the responsibility of the manufacturer. Therefore, the only recommendation we can rightfully make is to use an adhesive that the manufacturer claims as compatible with polystyrene foam.

The user needs to be aware of a few basic considerations when selecting an adhesive. Foremost on this list is the adhesive’s chemical compatibility with the polystyrene foam. The adhesive must not attack and cause cavitations of the polystyrene foam during the curing process. Open time and cure are other areas of consideration. Open time is the amount of time the user has from adhesive application to assembly completion. Cure time refers to the time period from the assembly to when the bond reaches optimum strength. The user should also consider the environment of the bond after it is cured. Does it need to withstand freeze/thaw cycles that would be common in the outdoors during the winter? Will water or high moisture levels affect the adhesive during or after it is cured? Will the adhesive need to remain pliable after cure to allow for slight movement in the assembly? The manufacturer generally considers these variables plus many others when formulating an adhesive. It is the responsibility of the user to determine if the adhesive chosen is suitable for the intended application.

T Clear does not recommend a particular adhesive for the use with STYROFOAM brand plastics. However, previous laboratory evaluations have shown certain adhesives to perform well with STYROFOAM. These adhesives demonstrated little or no cavitations to polystyrene foam at cure temperatures below 100˚F. The bond strength of these adhesives after cure was greater than the tensile strength of the foam.

The following is a list of these adhesives and their manufacturers:

The roof systems on textile manufacturing facilities must solve some very specific problems and no one knows this better than Jack Standridge, engineer and Assistant Vice President of the New Cherokee Corp., just outside Knoxville, Tennessee. Except for the 6 years spent pursuing a degree in Engineering at Clemson University while employed at a power company, Jack has been working in textiles since the age of 16. “My team and I are responsible for keeping the average fluctuation of temperature and humidity inside this plant to a minimum of + or-2°(%).

There is also an opportunity to reuse the LIGHTGUARD panels in the event of membrane failure, renovation or vertical expansion. LIGHTGUARD Ballasted Roof Insulation eliminates damage from windblown rocks from atop the roof because LIGHTGUARD does not require the use of crushed stone or gravel. Since 1981, Jack Standridge has completed 98% of the renovation of the roof at The New Cherokee Corp. “When the final 2% is completed, I don’t expect to see this roof again for another 20 years and by then I will be retired.” Jack considers LIGHTGUARD the long-term solution to his roofing problems.

An Overview of Current LIGHTGUARD Applications New Roofing System Critical For Renovated R. J. Reynolds Plant.

In the mid to late 1980’s, the R. J. Reynolds Tobacco Co., a subsidiary of RJR Nabisco Inc., initiated a major renovation of its Winston-Salem, N.C. manufacturing facility, built in 1960 and known as Whitaker Park. A pre-renovatin analysis of the facility’s existing roof indicated that the roofing membranes were nearing the end of their service lives; therefore, R. J.

An Overview of Current LIGHTGUARD Applications LIGHTGUARD Passes All The School Tests In New York State. With Honors.

When school administrators and architects specify roof systems for schools, they are looking to solve some very specific problems: long-term budget concerns, limited in-house maintenance staffs, damage to the waterproof membrane caused by contracted workers and vandals, and energy costs that are literally going through the roof. If those schools are in upstate New York, they must also concern themselves with the high cost of asbestos abatements and the shock to the membrane from temperatures that can range as much as 70° in a 24-hour period and reach lows of 30° to 40° below zero. What’s more, they need a roof system that can be installed quickly and easily. As roofing contractor Mike Monahan of Monahan & L to R: T. Clear approved contractor Mike Monahan, Pres.

An Overview of Current LIGHTGUARD and HEAVYGUARD Applications Husky Injection Molding Uses Sound Technology To Solve Roof Problems

There are some companies that focus on quality, believing that quality has its own rewards. Husky Injection Molding is one of those companies. Quality has it’s own costs, as well.

Clear Protected Membrane Roof Systems Applications Construction Coordinator Gets Education In Roof Systems At Duke University Medical Center

Duke University Medical Center has a lot of roofs. Approximately 300, comprising 2.5 million square feet of roof surface. So far. When Tim Pennigar, Coordinator of Medical Center Maintenance and Construction, arrived over 12 years ago, he will tell you, “We probably had one of every roofing system known to man out here. A real smorgasbord of construction from the 1920s on.” When Pennigar lead a second- generation of reroofing in the mid 1980s, he got a real education in what worked and what didn’t. And why. “We jumped on the single-ply bandwagon, using it to recover existing BURs. Some ® of those worked, but, because so many of Installing LIGHTGUARD on one of the many T.
