SIP build systems have been around since the 1930's, in fact, Frank Lloyd Wright used the system on his Usonian houses. Most SIP panels are made with Orientated Strand Board (OSB) today, we supply a version using German engineered Egger board with carbon treated EPS insulation.
Magnesium Oxide (MgO) sheathing board is a fireproof, highly water resistant alternative. Our MgO system is around 10 -20% more expensive than the standard OSB but there are many advantages. The panel (shown in the illustration above) will, in some cases be the finished wall. Render can be applied directly to external walls or battens can be affixed for timber cladding, brick slips can also be directly applied. Internally, if the wall has no services, plumbing or electrics etc, then the panels can be taped, filled and painted, we will soon have panels with integrated service ducts.
There have been problems with cheap MgO flooding some markets, so be very wary what you buy. We only use ResCom Magnesium Oxide, this is an Australian company with a stake in the manufacturing plant in China. This is the most certificated MgO product on the planet and conforms to all British Standard, ISO and EN classifications.
Our building system has CATG SIP Mark scheme approval. Our manufacturers are ISO9001 approved for our quality management system. Our manufacturers have ISO14001 certification for environmental management. All our engineered wood products have PEFC chain of custody certification. Our metal web eco joists are CE marked. Our manufacturers are full members of the STA.
