2 2 Vencel Resil is one of the UK s largest manufacturer s of expanded polystyrene (EPS) and under the Jablite brand, supplies a range of bespoke insulation products and solutions to the construction, industrial and housebuilding markets. Vencel Resil specialises in providing industry-leading insulation solutions that meet current and future Building Regulations requirements for the specification of floors, walls and roofs of commercial, public sector and residential buildings. Established in 1973, the company has been a member of the Synbra Group since Synbra is a multi-national organisation specialising in producing high quality EPS products throughout Europe. Being part of a European group means having the benefit of access to extensive resources and technology. Technical support Vencel Resil provides technical and design support and has a dedicated team of professionals who have extensive experience of working in the industry. Many clients find the technical support they receive invaluable in ensuring that specifications are in line with modern building requirements. Being more than just a manufacturer of EPS products, it is the company s expertise within this sector and the knowledge within its team which establishes Vencel Resil as one of the leading providers of high performance insulation. Jablite a market leading insulation material Vencel Resil has a major UK manufacturing base, where its Jablite expanded polystyrene products can be produced to specific grades and thicknesses to suit clients needs. As such, the company is constantly seeking ways to enhance the performance of the range. Jablite EPS is a proven insulation material, widely regarded as one of the most effective on the market, offering high thermal performance, unrivalled sustainability credentials, long-term durability, whilst ensuring its cost effectiveness in the market. Jablite Premium Jablite Premium is an innovative Low Lambda (EPS) insulation material that has the capacity to enhance a building s thermal performance by up to 20%. This enables builders and contractors to meet ever tightening Building Regulations without having to change their build practices A relatively new innovation in EPS insulation, Jablite Premium is becoming widely used in the floors, walls and roofs of domestic, public sector and commercial buildings. Instantly recognisable by its distinctive grey board with orange speckles, it provides the reassurances to architects, specifiers and contractors that the material used on site is the same as the one specified and, crucially, that the resulting performance matches the approved design intent. A major benefit of Jablite Premium is that it offers improved U-values without having to alter the thickness of the cavity wall or change the construction of the floor or roof. This ensures contractors on site maintain their efficiency, whilst clients benefit from maximum internal floorspace and low running costs. BRE Green Guide to Specification The Green Guide, produced by the British Research Establishment (BRE), assesses a range of building products environmental performance over their full life-span and awards them with a sustainability rating. EPS has achieved an A+, which is the highest rating possible and clearly demonstrates the material s excellent thermal and environmental credentials. The BRE ranks materials on the basis that the benefit of using any of the insulation types listed in the guide will outweigh the embodied environmental impact of their manufacture, installation and end-of-life disposal. Environmental credentials Expanded polystyrene is recognised for its excellent energy efficiency and low environmental impact. It has an ODP (Ozone Depletion Potential) of zero and a low GWP (Global Warming Potential), which is exemplary. Vencel Resil is fully committed to sustainability in all areas of its operation. Energy saving and modern methods of construction are all carefully considered when researching and developing new products, as well as end of life recyclability.

3 3Floor Insulation 3 APPLICATION: Product: Jablite Premium Board Jablite Premium board is suitable for insulating the internal face of all types of external wall construction, and can be used either in conjunction with 12.5mm plasterboard, or as the insulation part of a proprietary laminate. Jablite Premium board Jablite Premium board is available in a range of thicknesses for use in different wall-lining systems. It is an economical method of providing good thermal insulation and of reducing heating costs. Walls which have been internally insulated with Jablite Premium board respond rapidly to heat input and good standards of comfort are readily obtained. In buildings which are only heated intermittently, the risk of surface condensation is minimised. Easy to handle Jablite Premium board is manufactured from low lambda expanded polystyrene (EPS), which is lightweight and easy to handle. Permanent Jablite Premium board is rot-proof and durable and will remain effective for the life of the building; the recommended fixing methods will retain the boards permanently in position. It also has the added advantage of being flood-proof. Easily cut to fit If required, boards can be easily cut to length using a sharp knife. No specialised trades or equipment are required. Although this technique is commonly used to upgrade existing buildings, it is equally applicable to new build. Environment Expanded polystyrene has been awarded an A+ rating by the BRE s Green Guide to Specification. Type Jablite Premium board is supplied as EPS 70 as defined in BS EN Reaction to Fire Class E, containing a flameretardant additive. Dimensions Standard size: 2400 x 1200mm Standard thickness: 25, 30, 40, 50, 60, 75, and 100mm. Fire Jablite Premium board is manufactured containing a flame-retardant additive. When properly installed, the insulation is protected by the plasterboard (or other) lining and will have no adverse effect on either the surface spread of flame rating or the fire performance of the wall. Thermal Resistance The thermal resistance, R-value, of Jablite Premium board for a range of common thicknesses is as follows: 25mm 0.83m 2 K/W 30mm 1.00m 2 K/W 40mm 1.33m 2 K/W 50mm 1.67m 2 K/W 60mm 2.00m 2 K/W 75mm 2.50m 2 K/W 100mm 3.33m 2 K/W Water vapour transmission Jablite Premium board has a significant resistance to the passage of water vapour, but should not be regarded as a vapourcontrol layer. The risk of interstitial condensation can be reduced by placing a vapour-control layer between the Jablite Premium board and the plasterboard facing. U-values Tables show a selection of common wall constructions using a range of materials and give the U-values achieved according to the thickness of Jablite Premium board used. The values given are based on a k value of 0.030W/mK for the insulation.

7 7 APPLICATION: INSTALLATION Figures show typical methods of installing Jablite Premium board. Figure 20.2 Single layer insulation 1 1. Jablite Premium board 2. Vapour-control layer mm Plasterboard Single layer of Jablite Premium board Treated timber battens should be attached 2 to the wall surface at appropriate centres to suit the plasterboard. The size of the battens and the method of fixing should always be in accordance with the plasterboard manufacturer s instructions. The Jablite Premium board is tight-fitted between the battens. If the plasterboard does not incorporate a vapour control membrane, then a separate vapour-control layer, consisting of a minimum 1000g polythene, should be placed over the insulation, and the edges and joints sealed. Finally, the plasterboard should be fixed to the battens in accordance with the manufacturer s instructions, and finished as required. (See figure 20.2). Figure 20.3 Double layer insulation Jablite Premium board 2. Vapour-control layer mm Plasterboard Double layer of Jablite Premium board The method of installation is generally as 3 described above for a single layer system but a second layer of Jablite Premium board is fixed across the battens, taking care that the joints do not coincide. These boards should be pinned to the battens. The vapour control layer should be placed between the plasterboard and the second layer of insulation. (See figure 20.3). Composite boards The manufacturers of proprietary EPS/plasterboard and other EPS insulated composite boards have developed a range of adhesive and mechanical fixing systems for their products, and their recommendations should be followed. (See figure 20.4). Further information on manufacturers and suppliers of these products is available from Vencel Resil's technical department.

8 8 Vapour-control layer Jablite Premium board should not be regarded as a vapour-control layer. The risk of interstitial condensation can be reduced by placing a vapour-control layer between the Jablite Premium board and the plasterboard facing, or by using plasterboard which incorporates an integral vapour-control membrane. Solid-wall constructions Regardless of the method chosen for fixing Jablite Premium board, if the underlying structure consists of a solid, rather than cavity wall, a cavity should be provided between the wall and the insulation in accordance with the requirements of Building Regulations Approved Document C, Section C4. Choice of insulation thickness In most cases, the use of a single layer of insulation fitted between battens will not provide a U-value which satisfies the Building Regulations, and the use of a second layer of Jablite Premium board, fixed over the battens, rather than between, can be used to improve the insulation value to an acceptable level. (See tables ). Services Service runs should be fixed before the lining is installed. Any chasing for services should be made in the wall itself and not into the insulation. Jablite Premium board should not be allowed to come into direct contact with PVC-sheathed cable, nor closer than 12mm to hot-water pipes; cables should be protected by the use of a physical barrier, for example by being enclosed in a conduit.
