Product Guide.indd 36 17/06/2016 12:56:49 COVERWORLD ACOUSTIC PERFORMANCE Perforated Liner systems A perforated liner sheet is often specified when there is a requirement to reduce the levels of reflected sound inside the building. This will improve the sound quality and clarity inside the building and reduce the overall noise levels. The perforations in the liner sheet allow the airborne noise to more easily penetrate the cladding. This effectively reduces the airborne sound reduction index. The liner sheet can be either fully perforated (Effect of a perforated liner sheet on the sound reduction index) or the perforated area can be limited to the profile troughs.

The size, pattern and total area of perforation can vary between different systems. Increasing the level of perforation will generally reduce the airborne sound reduction index ACOUSTICS and increase the sound absorption coefficient.

Coverworlds standard perforated pattern is an R3T5, this means that the holes are 3mm in diameter in a triangular pattern at 5mm pitch.

Coverworld UK Ltd’s wide range of GRP rooflights offers a cost effective solution to providing natural daylight in buildings. With light transmission levels of upto 90%, Coverworlds GRP rooflights are ideally suited for use in retail, warehousing, industrial and agricultural projects. There are various configurations of single, double or triple skin systems in a variety of different fire ratings and weight classifications allowing Coverworld to supply GRP rooflights for almost any type of project.

GRP rooflights consist of a translucent glass reinforced polyester (GRP) with a Melinex film coating that helps to reduce the degradation and discolouring associated with prolonged exposure to ultra violet light. Specifying the correct type of rooflight for any given project is now becoming more important than ever before. Changes in the last few years regarding non-fragility classifications mean that the correct

choice of rooflight should be carefully considered ideally at the design stage. ROOFLIGHTS

NARM (National Association of Rooflight Manufacturers) has been able to recommend the minimum weights necessary to ensure that non-fragility ratings can be expected to be retained for 25 years, with typical maintenance regimes. The recommended minimum classifications for an expected 25 year non- fragility rating are shown in the table below;

Non-fragile Minimum Classification Application (rooflight type) Classification to BSEN1013: 2012 for expected to ACR[M]001 25 year non-fragility

Single Skin

Rigid trapezoidal profiles for use Class B 3.66kg/m2 with single skin metal sheeting

Rigid sinusoidal profiles for use with fibre Class C 3.06kg/m2 cement sheeting (see note 3) Double or Triple Skin site assembled with

flexible profile steel liners (typically 0.4mm) Class C Outer: 1.83kg/m² Liner: 2.44kg/m² Liner panel assembly only

Double skin assembly (where Class C non- Class B Outer: 2.44kg/m² Liner: 2.44kg/m² fragile liner is required e.g. when lining out)

Double skin assembly (where there is no Class B Outer: 3.06kg/m² Liner: 1.83kg/m² requirement for non-fragility of liner alone) Double or Triple Skin site assembled with rigid profile steel liners (typically 0.7mm) Liner panel assembly only Class B Outer: 1.83kg/m² Liner: 3.06kg/m² Double skin assembly Class B Outer: 1.83kg/m² Liner: 3.06kg/m² Factory assembled double or triple skin

Medium / low flexibility outer profile, separate Class B Outer: 3.66kg/m² Liner: 1.83kg/m² boxes between purlins (suspended box)

Notes: 1. It can be expected that the non-fragile classification of a oofr assembly incorporating these increased weight rooflights should be maintained for at least 25 years under all normal conditions, provided it has already been demonstrated that the roof system without rooflights, will retain the same non-fragile classification for that period. 2. The non-fragility classification will only be etainedr where all other components have been specified accordingly - for example fasteners will usually need to be stainless steel. 3. This recommendation only applies to rooflights for use with current reinforced fibre cement sheeting; obsolete asbestos and fibre cement profiles should always be treated as fragile.

Notes: 1. An assembly of a roof system incorporating rooflights of the minimum weight shown will achieve the relevant classification when new, provided it has already been demonstrated that the roof system without rooflights has an equal or better non-fragility classification. 2. This recommendation only applies to rooflights for use with current reinforced fibre cement sheeting; obsolete asbestos and fibre cement profiles should always be treated as fragile.

GRP rooflights of these weights are extremely durable and their strength will be retained in the long term.

ROOFLIGHTS However the period of non-fragility of these rooflights may vary between 5 – 20 years, depending on the possible effects of external factors, unless fully documented maintenance procedures are sufficiently comprehensive to ensure prevention of any factors which could render the rooflight assembly fragile.

Most typical maintenance regimes are not usually sufficient to achieve this and in the interests of safety it is prudent when accessing roofs incorporating these rooflights to take all the necessary precautions.

Product Guide.indd 64 17/06/2016 12:56:55 COVERFIX INSTALLATION Fastener Installation Guide & Safety Notes Coverfix fasteners are designed for installation ideally by operatives that are correctly trained in the use of professional fasteners. General rules for using Coverfix fasteners are; • It is imperative when installing all types of self drilling and / or self tapping fasteners that the nosepiece of the screwdriver is used and correctly adjusted. • Specialist electric screwdrivers are required to fix fasteners correctly. • Care should be taken not to over tighten fasteners / washer combinations as this may cause water ingress. It can also contribute towards increased air leakage and reduced pull-over as a result of washer inversion. • If the fastener doesn’t have a washer, the application should be checked prior to use. • As a guide the majority of aluminium / steel roofing applications require a 16mm or 19mm washer and the wall cladding requires only a 16mm washer. GRP profile sheets require a 29mm washer on the main fastener (ideally used with a poppy red colour cap for rooflight applications).

• Installing Coverfix Carbon Steel Self Drilling / Self appingT Fasteners • To install carbon steel self drilling / self tapping fasteners you will need a variable speed general purpose 110-volt screw driver that will run from approx 0 - 2500 RPM. If installing a large area using heavy steel it may be beneficial to use a heavy-duty screwdriver. The following speeds are for guidance only as each installation will vary but the slower a fastener is installed the higher the mechanical performance obtained. Do not put your full body weight on the screwdriver when installing fasteners as this may cause the fastener point to burn out.

Light Section Rail (Upto 3mm Thick) 1800 - 2500 RPM Heavy Section Rail (3mm To 12mm Thick) MAX 1800 RPM Stitcher Fixing (Sheet To Sheet) 1800 - 2500 RPM

Correct Installation Of Hex Head Fastener With Bonded Washers

Over tightened

Causes reverse dishing and potential leakage under seal.

Under tightened

Likely to cause leakage under seal and around fastener.

Correctly tightened Tight against surface, seal flows inward to seal minor fastener diameter and surface voids.

Product Guide.indd 65 17/06/2016 12:56:55 STORAGE & HANDLING STORAGE & HANDLING Throughout the manufacture and transit of Coverworld roofing and cladding materials, every care is taken to ensure they are delivered in first class condition. It is therefore essential the materials remain in this state before, and after, incorporation into the building works. Adequate on site storage and handling facilities should be provided to ensure that damage does not occur after delivery.

The following practices should be observed:

STORAGE

1. If the roofing and cladding materials are not for immediate use, they must be stored 1 safely. Always store sheets undercover. Never leave the stacks exposed to the weather or in locations where they might incur accidental damage.

2. When there are no indoor storage facilities available, the stacks must be protected with a tarpaulin or weatherproof sheet 2 supported on a scaffolding frame. Sufficient room on all sides should be left around the stack to allow air to circulate. Long term outdoor storage is not recommended. Adequate space should be left around stacks to allow access for site personnel.

3. Stacks should be raised clear of the ground on timber bearers. The bearers should provide good support, on firm ground, so 3 that the stacks are not bent, warped or twisted. The bearers should be spaced at no more than 900mm centres. Incline the stacks so that any penetrating water will drain off. Inspect the sheets regularly and check for leaks in the covering. ✔

Product Guide.indd 69 17/06/2016 12:56:55 HANDLING

4. Single sheets should be lifted from 4 the stack not dragged. Remove by ‘turning’ from the stack and lifting straight off. Never slide sheets off the stack as this will probably cause damage to ✘ the coating.

5. Whenever possible lift sheets manually 5 onto the roof or higher elevation. If hoisting into position is unavoidable, make sure the edges are fully protected and the pressure across the sheets doesn’t cause distortion. Use double or multiple slings or ropes for hoisting - never chains. ✔

6. Never store sheets where they can be 6 walked on or climbed over. Wear only soft sole shoes with a good firm grip when working on a roof. ✘ STORAGE & HANDLING
