The composite structure of Structural Insulated Panels offer many physical advantages:
Once completed, a SIPs structure forms a monolithic shell is up to seven times stronger than a conventional timber frame structure and is a popular building method in areas subject to earthquakes, tornadoes and hurricanes. This provides a building with a very robust and solid feel which can be indistinguishable from a traditionally constructed building once complete.
Airtight & Quiet
Buildings constructed with Structural Insulated Panels are quieter and more comfortable to live in. The panels provide significant resistance to airborne sound. The inherent airtight construction lends itself to modern ventilation systems which reduce energy costs and improve air quality.
Resistant to Rodents, Mould and Microbes
The PUR (Polyurethane) core and the OSB facings used in the manufacture of Enviropanel Structural Insulated Panels do not provide any food value to vermin and are resistant to attack by mould and microbes.
The solid core of rigid PUR foam insulation in the panels cannot slump over time and the minimal thermal bridging ensures that the building is heated evenly, free from cold spots and condensation. The building will benefit from reduced heating costs for its entire lifetime. This is an important consideration at a time of spiralling energy costs.
Rigid Surface for Fixings
The OSB skin of a SIPs structure provides a continuous surface for easy fixing of services, lights, radiators and kitchen units without having to build in additional support in the structure.
Structural insulated panels are relatively lightweight (approximately 25Kg/m2) and can allow a reduced foundation specification.
Choice of Finish
A SIPs structure will form the hidden shell of the building. The external walls can then be finished in many ways. These can include traditional cavity and facing brickwork, timber cladding, brick slips and render systems. Internal walls are normally finished with fire resistant plasterboard. Roofs are finished as normal with battens and tiles, although the inherent strength of a SIPs roof does not require the same weight of finish as a conventional vented roof void. This can allow the use of a lightweight roof finish if desired.
