Some panel systems are more 'structural' than others. For example, the Bondor Insuliving panel is only suitable for single storey construction with limited roof spans whereas some of the better OSB and MgO boards can be the structural frame/panel for multistorey buildings. A SIPS panel is a structural panel - no ifs, no buts. There are plenty of 'panel systems' out there that LOOK like a structural panel but are not. The best way to check is to ask for the engineering and give it to your Building Surveyor to confirm if the panels will suffice for a building permit. Builders are people too.... Re: Use of Structural Insulated Panels 38Jan 11, 2012 5:57 pm Thanks for clarification. That was my understanding - so some of the panels calling themselves structural are in fact not - just fill in panels and the panel itself should be the structure without the need for any other framing? That too was my understanding, so with that qualifier, there would be only one or two panels that can really authentically be called SIPs? Re: Use of Structural Insulated Panels 39Jan 14, 2012 2:07 pm I'm pretty intrigued by SIP construction. I've been looking at the Bondor Insulwall and SolarSpan stuff but hadn't realised till I read this thread that they are not suitable for multilevel construction. I've started looking at the PanEco stuff that seems to get a good rap here. Speaking of wrap .... where is the vapour barrier in SIP construction? Am I at all justified in being worried about condensation on the internal walls given there doesn't seem to be one? Re: Use of Structural Insulated Panels 40Jan 14, 2012 2:22 pm Yes, the plywood sips do have a vapour barrier and you are rightly worried about condensation and long term mould. The vapour barrier is a vital component and should be supplied with the panels. Builders are people too.... Good questions but the best answer will be obtained by visiting (ie: interviewing) a couple of house designers and/or builders and ask them.

There maybe should be an additional J1 between TB10 and T12 if… 3 27699 |
