What are SIPs?
Structural insulated panels (SIPs) are a high performance building system for residential and commercial construction. The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB).
SIPs are manufactured under factory controlled conditions. This offsite fabrication means that your weatherproof building shell can be complete just a few days after the ground works are ready to receive them.
SIP panels are either 142mm or 172mm thick. The panels are typically 1220mm wide and can be as long as 7.5 metres in length to suit each individual project.
SIPs are fabricated using timber from sustainable sources. SIPs use less timber than timber frame and are one of the most economical and eco friendly forms of construction.
The high strength to weight ratio of SIP Panels allows large sections of your building to be fitted at once, speeding up the time required on site for erection. The Offsite fabrication reduces waste and also helps reduce embodied and transport energy.
SIP insulation exceeds the current Building Regulation requirements on its own. The foam insulation has an Ozone Depletion Potential (ODP) rating of zero and has a low Global Warming Potential (GWP).
SIPs, through their strength and ease of connection, offer the designer more versatility than other construction materials, allowing possibilities beyond the conventional, such as sloping roof panels creating an open space that when utilised, properly maximises any building plot.
The result is a building system that is extremely strong, energy efficient and cost effective. Building with SIPs will save you time, money and labour.
The Key Advantages of SIP Buildings
SIPS buildings are generally more energy efficient, stronger, quieter and more airtight than older technologies. Less air leakage means less drafts, fewer noise penetrations and significantly lower energy bills, thus a reduction in CO2 emissions.
Modern methods of construction are utilised to factory produce your SIPS home or building meaning minimal wastage and less waste to landfill.
The OSB (Orientated Strand Board) that is utilised for the panels is from sustainable harvested spruce. Up to 35% reduction in the amount of timber utilised in a SIPS building.
A faster build program will reduce overall onsite costs due to reduced project management, cost of hiring scaffolding, plant, temporary accommodation, safety and security equipment, giving earlier cash recovery, improved cash flow and increased capacity.
SIPs are lightweight (approximately 25Kg/m2) making them easier and quicker to assemble on site. However SIPs are also noted for their superior strength. SIP buildings are capable of withstanding extreme climate and weather conditions.
Limited Cold Bridging due to the continuity of the rigid insulation within the system provides greatly enhanced thermal reliability, which in turn can provide a platform to achieve Code Level 4 and 5 for Sustainable Homes.
