Assessment and Technical Investigations The following is a summary of the assessment and technical investigations carried out on Alreflex 1L-1 and Alreflex 1L-1 Super R Class 0. Page 3 of 12

4 Design Considerations 3 General 3.1 Alreflex 1L-1 and Alreflex 1L-1 Super R Class 0 are effective in reducing the thermal transmittance (U value) and providing a rain barrier in new cavity walls with masonry inner and outer leaves (where masonry includes clay and calcium silicate bricks, concrete blocks and natural and reconstituted stone blocks). It is essential that such walls are designed and constructed to incorporate the normal precautions to prevent moisture penetration. 3.2 New buildings subject to national Building Regulations and Standards should be suitable when assessed in accordance with the relevant recommendations of: BS : In particular, Clause Exclusion of water of the Code of practice should be followed in that the designer selects a construction appropriate to the local wind-driven rain index paying due regard to the design detailing, workmanship and materials to be used BS : Other new buildings not subjected to any of the above should also be built in accordance with BS : 2005 and BS : As with any other form of cavity wall insulation, where buildings need to comply with NHBC Standards 2008, specifiers should observe the requirements of these Standards. 3.5 The products are for use in any exposure zone. However, the use of the products does not preclude the need to apply an external render coat or other suitable finish in severe exposure zones where such application would be normal practice. 3.6 To reduce the risk of water penetration, raked or recessed mortar joints should be avoided in severe or very severe exposure zones. 3.7 The use of cavity battens and/or boards is strongly recommended to prevent bridging by mortar droppings. 3.8 As with all cavity wall insulation, the construction and detailing should comply with good practice as described in the BBA joint publication Cavity Insulation of Masonry Walls Dampness Risks and How to Minimise Them. They are particularly important in areas subject to severe or very severe driving rain. 3.9 It is essential that during construction and the installation of the products the following conditions are observed: the first leaf must be left long enough to develop some strength (for example, overnight) before installing the products (see section 12 of this Certificate) the cavity where the products are installed must have a design width of not less than 57 mm nor must it exceed 75 mm with the approved wall ties of 2.8 mm diameter or 100 mm with approved wall ties of 4 mm diameter wall ties should be installed correctly once installed, and before the second leaf is built up, the exposed ends of the wall ties pose a risk of injury to building operatives. Extra care should be taken during this period and the use of eye protection is recommended approved methods of fixing must be used consecutive strips of the product must be installed with an overlap of 150 mm weathered to the outside. Horizontal or vertical butt joints are not permitted and vertical lap joints should be kept to a minimum correct weathering of laps will occur automatically when the inner leaf is built first. Constructing the outer leaf first should be carried out only if the site labour is fully aware of the installation requirements and where it is impossible to build the inner leaf first It is recommended that installation is carried out to the highest level on each wall, or that the top edge of the insulation is protected by a cavity tray. Buildings up to and including 12 m 3.11 This Certificate covers the use of the products in any exposure zone subject to compliance with the conditions stated in section 3.5. Buildings over 12 m and up to and including 25 m 3.12 The following additional requirements apply: from ground level the maximum height of continuous cavity walls must not exceed 12 m; above 12 m the maximum height of continuous cavity walls must not exceed 7 m the specifier must take extra care when detailing to ensure that the introduction of the products does not affect the weather resistance of the wall. Site supervision is recommended during the installation of the products the exposure factor does not exceed Practicability of installation The products are designed to be installed by a competent general builder, or a contractor, experienced with this type of product.

5 5 Thermal performance 5.1 Calculations of the thermal transmittance (U value) of specific external wall constructions should be carried out in accordance with BS EN ISO 6946 : 2007, BRE report (BR 443 : 2006) Conventions for U-value calculations, using an emissivity of 0.05 of the foil equal to a cavity resistance value of m 2 K W 1 when installed with a 25 mm air space. Example U values are given in Table 2. A thermal resistance (m 2 K W 1 ) of the products when installed with a minimum air space of 25 mm on either side for the products can be taken as: Alreflex 1L Alreflex 1L-1 Super R Class Table 2 Typical cavity wall U values (W m 2 K 1 ) Product Aerated concrete block Medium concrete block Dense concrete block λ = 0.12 W m 1 K 1 λ = 0.32 W m 1 K 1 λ = 1.13 W m 1 K 1 d = 400 kg m 3 d = 1300 kg m 3 d = 1800 kg m 3 Alreflex 1L mm Alreflex 1L-1 Super R Class mm The U value of a completed wall will depend on the selected insulation thickness and the insulating value of the masonry and the internal finishes. 5.3 When considering insulation requirements, designers should refer to the detailed guidance contained in the documents supporting the national Building Regulations. The U values shown in Table 2 indicate that the product can enable, or contribute to enabling, a wall to achieve typical design U values referred to in those supporting documents. See Tables 3 and 4. Table 3 Typical design U values for walls England and Wales, and Northern Ireland Construction type U value (W m 2 K 1 ) Mean for new extensions (1) 0.30 Notional mean in SAP and SBEM and limit mean for new-build 0.35 Mean for replacement, renovated and retained walls (1) 0.35 Individual limit for new-build and flexible approaches (1) 0.70 (1) Alternative or flexible approaches are given in relevant documents supporting the national Building Regulations. Table 4 Typical design U values for walls Scotland Construction type Notional mean for dwellings in SAP and the simplified approach: solid fuel, package 6 other fuels, packages 1-5 U value (W m 2 K 1 ) Mean for new extensions, conversions and alterations (1) 0.27 Notional mean for non-domestic in SBEM and limit mean for new-build 0.30 Individual limit for; new-build, extensions, conversions, alterations and stand-alone domestic buildings less than 50 m (1) Alternative or flexible approaches are given in relevant documents supporting the national Building Regulations. New buildings 5.4 Walls with U values lower than (or the same as, for dwellings in Scotland) the relevant notional value specified in Table 3 or 4 will contribute to a building meeting its Target Emission Rate. Walls with higher U values will require additional energy saving measures in the building envelope and/or services. 5.5 The products can maintain, or contribute to maintaining, continuity of thermal insulation around openings and at junctions between external walls and other building elements. Details shown in Figure 1 will allow use of the default psi values for Accredited Construction details in Emission Rate calculations to SAP 2005 The Government s Standard Assessment Procedure for Energy Rating of Dwellings or the Simplified Building Energy Model (SBEM). Detailed guidance in this respect and on limiting heat loss by air infiltration can be found in: England and Wales Limiting thermal bridging and air leakage: Robust construction details for dwellings and similar buildings TSO 2002 or Accredited Construction Details (version 1.0) Scotland Accredited Construction Details (Scotland) Northern Ireland Accredited Construction Details (version 1.0).

6 Existing buildings 5.6 For existing buildings, extensions, conversions etc, walls will be acceptable where they do not exceed the relevant U value in Table 3 or 4 and junctions and openings comply with section 5.5. Figure 1 Junctions 150 mm minimum 6 Liquid water penetration 6.1 When the product bridges the dpc in walls, dampness from the ground will not pass through to the inner leaf provided the wall is detailed in accordance with the requirements and provisions of the national Building Regulations: England and Wales Approved Document C, section 5 Scotland Mandatory Standard 3.4, clause (1) (1) Technical Handbook (Domestic). Northern Ireland Technical Booklet C, Section Constructions built in accordance with BS : 2005, will prevent water reaching the inner leaf in damaging amounts. Water penetrating the outer leaf of the wall, will drain down the cavity face of the outer leaf and the product will contribute to satisfying the national Building Regulations: England and Wales Requirement C2(b) Scotland Mandatory Standard 3.10, clause (1)(2) (1) Technical Handbook (Domestic). (2) Technical Handbook (Non-Domestic). Northern Ireland Regulation C4(a)(b). 6.3 In all situations it is particularly important to ensure during installation that: the dpc should not project into cavity at ground-floor level as it can lead to catching mortar droppings installation is to be carried out to the highest level on each wall or the top edge of the insulation is protected by a cavity tray wall ties are installed correctly and are thoroughly clean the products are properly installed with weathered lap at lintel level, a cavity tray, stop ends and weepholes must be provided excess mortar is cleaned from the cavity face of the leading leaf and any debris removed from the cavity mortar droppings are cleaned from the exposed edges of installed product.

7 7 Condensation Surface condensation 7.1 Walls will limit the risk of surface condensation adequately when the thermal transmittance (U value) does not exceed 0.7 W m 2 K 1 at any point, and the junctions with floors, roofs and openings are designed in accordance with section 5.5 or 5.6 of this Certificate. 7.2 For buildings in Scotland, constructions will be acceptable where the thermal transmittance (U value) of the wall does not exceed 1.2 W m 2 K 1 at any point and openings and junctions with other elements comply with the guidance given in BS 5250 : 2002, Section 8 or BRE report (BR 262 : 2002) Thermal insulation: avoiding risks. Interstitial condensation 7.3 Walls will limit the risk of interstitial condensation adequately when they are designed and constructed in accordance with BS 5250 : 2002, Section 8 and Annex D. 7.4 The products have a nominal vapour resistance exceeding 125 MN s g 1 and, therefore, will provide a significant resistance to water vapour transmission. 7.5 If the products are to be used in the external wall of rooms expected to have high humidity, care must be taken to provide adequate permanent ventilation to avoid possible problems from the formation of interstitial condensation in the internal wall leaf. 8 Behaviour in relation to fire 8.1 The products are classified according to the surface spread of flame rating when tested on the foil face as: Alreflex 1L-1 Class 1 Alreflex 1L-1 Super R Class The products do not prejudice the fire-resistance properties of the wall. Although the product is combustible, it is unlikely to become ignited within the cavity when used in the context of this Certificate. If fire does penetrate into an unventilated cavity, the amount of air present will be insufficient to support combustion and flame spread will be minimal. 8.3 The requirements of the Building Regulations relating to fire spread in cavity walls can be met in buildings of all purpose groups without the need for cavity barriers, provided the construction complies with the provisions detailed in: England and Wales Approved Document B, Volume 1, Diagram 13, and Volume 2, Diagram 34 Northern Ireland Technical Booklet E, Diagram 3.5. A summary of these provisions is given here: England and Wales and Northern Ireland the wall must consist of masonry inner and outer leaves, each at least 75 mm thick the cavity must be closed at the top of the wall and at the top of any opening domestic meter cupboards may be installed provided there are not more than two to a dwelling, the opening in the outer leaf is not more than 800 mm by 500 mm for each cupboard, and the inner leaf is not penetrated except by a sleeve not more than 80 mm by 80 mm, which is fire-stopped combustible materials may be placed within the cavity (England and Wales only) the cavity must not be more than 300 mm wide (Northern Ireland only) in addition to the insulation, in Northern Ireland, only the following should be placed in, or exposed to, the cavity: timber lintels, window or door frames, or end of timber joists pipe, conduit or cable dpc, flashing, cavity closer or wall tie. 8.4 For constructions not covered by section 8.3, cavity barriers must be provided to comply with: England and Wales Approved Document B, Volume 1, Section 6, and Volume 2, Section 9 Scotland Mandatory Standard 2.4, clauses (1)(2), (1)(2), (1)(2) and (1)(2) (1) Technical Handbook (Domestic). (2) Technical Handbook (Non-Domestic). Northern Ireland Technical Booklet E, Paragraphs 3.35 to The products are combustible but may be used not more than one metre from a boundary, in walls with two leaves of masonry/concrete at least 75 mm thick, with barriers around all openings and at the top of the wall in accordance with Mandatory Standard 2.6, clauses (1) and (2). (1) Technical Handbook (Domestic). (2) Technical Handbook (Non-Domestic). 8.6 Cavity walls should always have a cavity closer at the top of the cavity and around openings. The materials must not be taken past fire stops. If fire does penetrate into an unventilated cavity, the amount of air present will be insufficient to support combustion and flame spread will be minimal. Page 7 of 12

8 9 Proximity of flues and appliances When installing the products in close proximity to certain flue pipes and/or heat producing appliances, the relevant provisions of the national Building Regulations are applicable: England and Wales Approved Document J Scotland Mandatory Standard 3.19, clause (1)(2) (1) Technical Handbook (Domestic). (2) Technical Handbook (Non-Domestic). Northern Ireland Technical Booklet L. 10 Maintenance As the products are confined within the wall cavity and have suitable durability (see section 11), maintenance is not required. 11 Durability When correctly installed, the products are durable, rot-proof, water resistant and sufficiently stable to remain effective as an insulant for the life of the building. Installation 12 General The walls are constructed leading with either the inner or outer leaf. It is recommended that the inner leaf be constructed ahead of the outer leaf as this will ensure the laps are weathered to the outside (see Figure 2). Figure 2 Typical installation detail 150 mm minimum 13 Procedure 13.1 Walls are constructed in the conventional manner with the first run of wall ties as near as possible to, though not directly on, the damp-proof course. A section of the inner leaf of the wall is built up using the special wall ties (see Figure 3) to a height of approximately 1.5 m to accommodate an initial run of product, 1.2 m wide. For this initial run (lane) wall ties should be installed in the first, third, fourth and sixth block bed joint at 900 mm horizontal centres. The ties are installed with the triangular end embedded in the mortar and the downstand loop butted against the cavity face of the leaf. Any mortar extrusions must be removed before setting. The leaf should be left for a minimum of eight hours so that, when the product is pushed over the ties, sufficient strength has developed to prevent disturbance of the ties and damage to the walls. Page 8 of 12

9 Figure 3 Cavity wall tie and clip for use with Alreflex (all dimensions in mm) The time required for adequate strength will vary depending on several factors, such as type of masonry, mortar, or weather conditions When the first leaf has developed sufficient strength the product is fixed in a horizontal lane. The top edge of the foil should be aligned 75 mm above the top row of wall ties to create a weathered lap. The product should be fixed at one end and then stretched out along the wall and pushed over the wall ties It is preferable for two people to carry out this operation; one to maintain tension and the other to push the product over the ties The products are held in position against the loops in the wall ties by the plastic clips pushed onto the ties (see Figure 3). A check should be made to ensure that the gap between the material and the inner leaf is maintained After the initial run of the products has been installed, the second leaf is built up to one course below the uppermost row of wall ties leaving room for the installation of the following run. The first leaf is raised by approximately 1.2 m to accommodate a 1.05 m width of the products. The wall ties are installed at 450 mm vertical centres and 900 mm horizontal centres. The products are installed applying the same techniques as for the initial run. The construction sequence incorporating 1.05 m widths of the products is repeated up to the required height A lap of 150 mm, weathered to the outside, must be incorporated on the wall ties between successive lanes. The correct weathering will occur automatically if the inner leaf is built up first. If for other reasons it is essential to build the outer leaf first, then the top of the products should not be clipped but folded back. After the lane above is clipped in position, it can be straightened and clipped over the bottom edge of the upper lane, creating a weathered lap. Close supervision of this installation method should be observed Localised contact with one leaf is permitted but must be kept to a minimum The lowest lane of foil may be allowed to protrude below damp-proof course level to provide some edge insulation for the floor. Where two lanes abut, they must be fixed with an overlap of 150 mm and the ties pushed through the core of the overlap (see Figure 4). Page 9 of 12

Construction can also begin with the outer leaf although care must be taken to lap the Alreflex to the outside of the building as shown At external corners, the products are spaced away from the inner leaf by bedding the plastic clips, at regular intervals, into the mortar. At internal corners, special ties, formed by cutting 95 mm from the free end of standard ties, are used to hold the products in position [see Figures 5(a) and 5(b)] The foil can be easily cut with a sharp knife or scissors to fit windows, doors and apertures. Where the foil meets a window or door frame it should be fixed to the jambs and cut off (see Figure 4). The products may be used to provide some insulation at joints (see section 5.1). Care should be taken to avoid bringing the foil into contact with the inner leaf (see section 13.7). Fixing at the tops of walls depends on the method used to seal the cavity; the material can be dressed under the cavity closure (see Figure 5c) or, where appropriate, weathered to a cavity tray. Where vertical joints occur in the material, they should be formed on wall ties with a 150 mm vertical lap (see Figure 5). Page 10 of 12
