1 Modern Offsite Construction Methods

2 COMPANY PROFILE Celebrating Over 85 Years Of Innovation. Established With over 85 years experience manufacturing composite insulated panels, we are dedicated to product development and continually strive to push the barriers of SIP technology with our Residential and Commercial product ranges. Hemsec SIPS manufacture light weight, polyurethane (PUR) foam injected, factory engineered Structural Insulated Panels that have been extensively tested for Structural, Acoustic and Thermal properties including Fire Resistance performance. With a focus towards Modern Methods of Construction (MMC) and environmentally friendly sustainable products - Hemsec SIPs are designed for internal and external, wall and roof applications for domestic and commercial construction solutions amongst building sectors including: Residential, Education, Leisure and Retail. SIPs are a Fabric-First approach, easily integrated with a wide range of construction materials, as a load or non-load bearing structure, to provide a built up - through wall panel system. Hemsec SIPS are BBA / NHBC approved and are eligible for Premier Guarantee.

4 RESIDENTIAL The Hemsec SIPs Residential panel comprises of BBA Approved 11mm Internal and External Oriented Strand Board (OSB) grade 3 facings with a rigid Polyurethane (PUR) foam core. The standard panel width is 1200mm and can be supplied in lengths up to 6000mm. Suitable for structural envelopes, partition walls and infill panels in single or multistorey framed buildings where construction demands are reduced. The availability of off-site pre-fabricated panels enables greater precision and quality control prior to arriving on site therefore reducing construction times by up to 60% which can allow the building to be weather tight in just a few days. The superior insulation of SIPs over traditional building methods allows the wall and roof panel thickness to be reduced, which can increase the living space for the same overall building footprint. SIPs can be used in place of standard roof trusses, providing additional living space with a room in the roof and vaulted ceilings. Due to the enhanced thermal efficiency of SIPs, a significant reduction in heating bills can also be achieved. To complete the building; a variety of external claddings including: Brick, Brick Slips, Timber Cladding, Render, Terracotta Tiles, Slates, Roof Tiles, Metal Standing Seam and Single Ply Roof Membranes can be utilised with SIPs.

Externally finished with red york handmade long format brick, off-white wetherby thin coat silicone K Finish render & white-oiled oak timber cladding. Protan single ply membrane roof finish with decorative ballast. Timber & aluminium composite windows in a mid-grey finish.

5 COMMERCIAL The Hemsec SIPs Commercial panel comprises of BBA Approved 15mm Internal and External Oriented Strand Board (OSB) grade 3 facings with a rigid Polyurethane (PUR) foam core. The standard panel width is 1200mm and can be supplied in lengths up to 6000mm. Suitable for structurally demanding projects as loadbearing or nonloadbearing walls and roofs that are easily integrated with a wide range of construction materials. Foundation specifications can be significantly reduced due to the lightweight nature of SIPs. The panels can form a structural shell which is up to seven times stronger than a conventional timber frame build, in multi-storey applications SIPs can be utilised directly on top or to the external face of the floor slab. SIPs allow for a faster build program when compared to traditional methods which minimises overall onsite costs by reducing project management, scaffold/plant hire, welfare facilities and labour. This can ultimately allow for an improved cash flow throughout the build and achieve an earlier occupancy. Provided the installation remains weathertight and damp-proof, a life of at least 60 years may be expected.
