2 OVERVIEW

Product definition realROOF is a tiled roof extension solution. In summary, it is a packaged solution, off site manufactured for rapid assembly and compliance with relevant Building Regulations. To demonstrate compliance to Building Regulations, realROOF has been issued with LABC Registered Details. realROOF is classed as a ‘warm roof’ and gives a vaulted/loft type ceiling. There are three major elements to realROOF;

1 2 3

1. A patented box eaves beam, filled with EPS beads as used in cavity insulation - that forms the soffit structure - approx 450mm front to back depth. 2. A hidden structural aluminium framework for hips, ridge and starter bars. 3. Mechanically fixed Kingspan Unidek Aero Structural Insulated Roof Panels are attached to the box eaves and structural framework.

Once it is counter battened and roofing membrane fixed (both supplied) the selected slates/tiles and battens are attached in the usual manner. (These items are not supplied - see list of what is/not supplied on page 61)

Key performance criteria - The product can be designed with window frames to all elevations, full masonry walls or brick piers. realROOF can be specified with its own structural support posts. - If bi-folding doors are to be used they MUST be bottom supported NOT top hung. - The standard soffit projects approx 150mm beyond external masonry - box eaves beam is approx 450mm front to back depth. - Pitch range suits all commonly available tiles/slates/metal roof coverings – pitch range: 15° - 45°. Always check with the roof covering manufacturer on the minimum pitch for your selected tile/slate brand. U-Design - System ‘U’ values - with the 190mm Unidek Aero panels is 0.16W/m2°C U-Design is a piece of design and with the 240mm Unidek Aero panels it is 0.13W/m2°C configuration software that exclusively (240mm is used in larger projection gable style lean - to’s due to its specifies realROOF extensions.

3 USING THE REALROOF GUIDE - WORKED EXAMPLE

The only accurate way to specify realROOF is using U-Design software. Either use a licensed copy of the software or send a sketch to Ultraframe or one of its approved trade intermediaries / distributers, where the information will be input on your behalf.

Worked Example

A 4m x 4m* gable fronted extension with a 25 degree Marley Modern tile is proposed at the rear of a semi detached property in the small market town of Clitheroe. The homeowner wants to know if they can have Velux roof windows and what size and how many.

Turn to page 12, the correct page for the style of extension (in this case Georgian) and use the chart that shows the pitch range (defined as 25° for this project) .As the project is defined as 4m x 4m, look up the loading for this size which is in Zone 2 light blue and which shows realROOF can accept a load of 1.18kN/m2 from wind and 0.6kN/m2 from snow

Now check how high above sea level the location is (Google search or try www.maps-streetview.com) – in this case it’s 76m elevation above the sea level. As outlined p12 in the worked example in red above, the location is in a small town (not the country).

Use figure 1 to check the wind speed at the location (in this case its 23 m/s which translates on table 1 to 0.68 kN/m²). From figure 2 check the snow load at the location (which is fig1 0.6kN/m²). fig2

Loads at postcode Max System Load System load MUST EQUAL (kN/m2) (kN/m2) or EXCEED post cope load

SNOW 0.60 0.60 WIND 0.68 1.18 Both figures at the actual site are within the design parameters of the realROOF system, so it is OK to proceed with the project with no amendments.

And finally, to determine the number and size of Velux roof windows that can fit into this extension, turn to page 56 and 57 to look up the vent opening sizes that can be configured p56 into each elevation. p57

If you are unable to achieve the desired size for your realROOF project please contact Ultraframe’s Technical Support Team for advice. (See p2 for contact details). 4 STRUCTURAL SPECIFICATION GUIDELINES

The size limitations for the realROOF are dependent on a number of factors primarily:- • Geographic Location • Roof Finish • Supporting Structure

1. Geographic Location The location of the build will alter the imposed load on the finished structure (both wind and snow loadings will have an impact). The size of these loads can be obtained from U-design software as the roof is being specified. U-design uses historic weather datafiles which from a postcode can provide both wind and snow loadings. If you do not have access to U-design the maps will help guide you to the approximate loadings. This will not give you exact values but ones likely to be the worst case for your location.

If you are unable to achieve the desired size for your realROOF project please contact Ultraframe’s Technical Support Team for advice. (See p2 for contact details).

The Map in figure 1 shows the fundamental basic wind velocity, vb,map in m/s. Find your approximate location and determine windspeed. Now you need the height above sea level in metres, this could be obtained via Ordnance Survey or Google Maps. Determine if your site is town or country.

Now use Table 1 Below to establish the load in kN/m2 and finally, check with figure 2 to see the snow load.

4. Appropriate fixings The correct selection/specification of fixings for realROOF to host wall and support posts to strip footings/foundations is CRITICAL. Ultraframe recommends HILTI chemical anchors but not expanding anchors .Using HILTI product codes/descriptions, use a HIT-V 80mm x M8 threaded anchor (stud*) fastened into a 10mm clean drill hole with gun injected mortar or adhesive capsules (with a minimum 80mm embedded) - always rigorously follow manufacturers guidance www.hilti.com

In addition Ultraframe recommends the following alternatives; Fischer M8/M10 masonry injection anchor FIS V Rawl Fixings M8/M10 CFS RM50 or CFS RP30

* Design load for each stud 2.5kN

A highly glazed extension - follow size guidelines as on p10 - 21 The incorporation of substantial brick piers will allow greater projections or will ensure the project can take heavier loads, size for size, when compared to a highly glazed extension. Ask the Technical Support Team for guidance (see page 2 for contact details) 7 PRINCIPLES OF GOOD EXTENSION DESIGN

1 Traditional construction practice would show case examples 2 & 3 as typical ways to proceed. However, with Ultraframe’s realROOF, the product introduction of an effective boxgutter can simplify build time/ cost and provide and elegant yet contemporary extension. 2

8 PRINCIPLES OF GOOD EXTENSION DESIGN

Whenever there is a joint between two sections of box eaves beam a support post is necessary. Think carefully about the customers preferred design and the shape/configuration of the host wall. Diagram 1 & 2 shows what can happen with a potentially unsightly floating support post the result. However prudent design and specification can allow this necessary support post to be cloaked in a cupboard or integrated into book shelves

The roof can be constructed with a variety of post and brick pier combinations. The critical criteria are:

1. Support at each corner 2. Maximum unsupported span is 4m 3. Maximum individual beam length is 6m i box beams can be jointed and require support by a post or with the joint positioned mid pier. 4. Box beam joints to be minimised

Guidance on brick pier sizing As the UK’s dominant building material it can be wrongly assumed they are suitable for all situations. Bricks largely rely on their mass to provide stability particularly given the relatively uncontrolled way in which mortar is mixed on site.

Brick piers can fail in two ways – 1) through flexure where wind is hitting the wall head on, bending the wall between the ground and the roof and 2) is lateral stability where the wall is supporting the adjacent panel.

This is the guidance on brick pier construction, given the rules above.

Where the construction is brick and block alone the minimum size of pier is 787mm (3.5 bricks). Where a windpost is incorporated such as an Ancon WP1 or WP3 this prevents the flexural failure and the pier can be reduced to 450mm (2 bricks) - A full height strap is used to provide additional performance to the post. Beyond this point the lateral stability becomes the limiting factor and a portal leg with secure fixings to the foundations is required, such as the realROOF standard posts.

When the box beam is sat on Other solutions are possible but it is necessary to consult a structural engineer for what a narrow pier use the narrow is most appropriate for the unique set ofconditions at any particular project. PLEASE pier internal brace and secure NOTE: LABC Registered Details/Approvals are for the roof structure and do NOT cover the into place existing masonry or and new brickwork/piers etc.

To see the total range of posts and options, please see Appendix 2 (p44) and Appendix 5 (p59)

23 SPREAD RESTRAINT STRAP

To prevent spread of the roof against the host building it my be necessary to include a strap.

The spreading forces can ordinarily be contained within the adjoining brick wall however there will be occasions when this wall does not have enough strength.

Examples of this are shown below:-

1. No return on the brick wall (the return should be a minimum of 750mm 2. The height of the brick work across the face is insufficient as in bungalow situations. (If it is less than 1000mm, a strap is specified)

2. Not enough brick work above door to transfer load. 1.Return on brickwork less than 750mm i.e. less than 1000mm

IMPORTANT The installer is responsible for ensuring that where realRoof is supported by means such as masonry or timber frame walls rather than realROOFs own support posts/beams, the structure provides enough lateral support and resistance to wind uplift. Further guidance can be obtained through realROOF’s technical documentation/guides – we strongly recommend the use of the realROOF structural support posts/beams Ultraframe cannot accept responsibility for the overall structural stability of an extension utilising realROOF. Nor can Ultraframe be responsible for the structural adequacy of any existing building work used as part of an overall project. Whilst assistance is provided ultimate responsibility for securing Building Regulations and planning permission lies with the retail installer.

59 APPENDIX 6 CAVITY TRAY ASSESSMENT / VERTICAL DPC REQUIREMENT

Overview realROOF will - in Building Regulations - be classed as an extension. The new extension will be a habitable room and so there must be no moisture ingress.

1. Vertical DPC In all situations/locations, a vertical DPC must be used where the new extension abuts the existing house wall. Determine the position of the slot - see drawing alongside. Chalk a vertical line on host wall. Before cutting slot, it is necessary to insert additional ties. Ultraframe recommends Helifix Dryfix ties - see www.helifix.co.uk/products/ remedial - products/dryfix. For full installation details and to calculate Dryfix sizes, visit the website or call 0208 735 5222.

To each side of the chalk line and within a maximum of 225mm each side, drill appropriate pilot hole through outer leaf and into the inner leaf by a minimum of 25mm - this should be undertaken every fourth course, into the brickwork (not joint), with the Dryfix alternating each ride of the slot. Insert appropriate Helifix masonry Dryfix ties using their insertion tool fitted to an electric SDS hammer drill.

2. Cavity Tray Assessment. In zones 1 and 2, cavity tray installation is based upon risk assessment - factors include determining if elevation faces prevailing wind, absorbancy of brickwork and monitor joint type. Cavity trays MUST be installed in severe/very severe exposure zones (3 and 4).

Approximate KEY EXPOSURE ZONES wind-driven rain* (litres/m² per spell)

1 Sheltered Less than 33

2 Moderate 33 to less than 58.5

3 Severe 58.5 to less than 100

4 Very Severe 100 or more
