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 1996. 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.
Insulation 3Floor APPLICATION: Products: Premium and Premium insulation can be used in all floor constructions for both domestic and commercial buildings. The application will determine the grade of Premium required for your project. Premium is mainly used for domestic floors, whereas Premium is widely used for commercial floors where higher loadings are likely to be encountered. Premium Premium and can be used below the concrete slab in solid groundfloor constructions to satisfy the relevant U-value requirements. Easy to handle Premium is manufactured from expanded polystyrene (EPS) which is lightweight and easy to handle on site Permanent Premium is rot-proof and durable and will remain effective for the life of the building. It also has the added advantage of being flood-proof. Rapid construction No specialised trades or equipment are required. Versatile Premium can be used above or below the damp-proof membrane. Environment Expanded polystyrene has been awarded an A+ rating by the BRE s Green Guide to Specification. Type Premium is supplied as EPS and as defined in BS EN 13163 Reaction to Fire Class E, containing a flameretardant additive. Approvals Premium has been assessed and approved by the British Board of Agrément for use below the concrete slab in solid ground floors; Certificate number 87/1796. Dimensions Standard size: 2400 x 1200mm. Standard thicknesses: 25, 30, 40, 50, 60, 75,, 120, and 200mm (Other thicknesses available to order) Fire Solid ground floors are not required to provide fire resistance. When properly installed, Premium is fully protected by the concrete slab, and will have no adverse effect on the fire performance of the floor. U-values The rate of heat loss through a ground floor varies with its size and shape. The thickness of insulation required to meet a given U-value will similarly depend on the size and shape of the floor. Approved Documents L1A, L1B, L2A and L2B guide you to BS EN ISO 133 as the method for determining floor U-values based on the floor perimeter and floor area where: P is length of exposed perimeter in metres and A is floor area in square metres. The measurement of both the floor area and perimeter should be made on the internal finished surface of the walls enclosing the heated space; unheated areas such as garages, porches and storage spaces need not be included. For buildings such as terraces or blocks of flats and apartments, the measurement should be taken over the total gross ground-floor area. Table 1.1 shows the required thicknesses of Premium and, to meet U-values of 0.25, 0.22, 0.20, 0.18, 0.15 and 0.10W/m 2 K.

5Floor Insulation APPLICATION: Figure 1.1 Concrete slab Premium edge strip Premium Damp-proof membrane
6 INSTALLATION Damp-proof membrane Premium should not be regarded as a damp-proof membrane (DPM). A suitable DPM must be provided, positioned either above or below the Premium, or on top of the concrete slab; (See figures 1.2 1.4). Liquid membranes are positioned above the slab. The hardcore should be blinded before receiving either the Premium or the DPM. If a liquid DPM is used, care should be taken that it is compatible with the Premium and that it is completely dry before the insulation is laid. Premium Premium should be loose-laid over the prepared surface; all joints should be tightly butted. If the concrete slab is to be poured directly onto the Premium, the joints should be covered with 75mm-wide adhesive tape to prevent the ingress of concrete or grout between the boards. Vertical upstands of Premium edge strip should be used around perimeter to prevent cold bridging, as detailed in BRE Report 262. Concrete slab The concrete slab is laid to the required thickness and either tamped or powerfloated to provide the required finish. During these operations, the surface of Premium or the DPM should be protected from impact damage or excessive trafficking by the use of spreader boards.
