Anyone built a SIPS garage?

We are seriously considering knocking down our old, cold and damp (in winter) garage and replacing it with one we can use all year round. I like the idea of SIPS panels because of their thermal efficiency, speed of assembly and the interesting open spaces you can create.

Has anyone built a SIPS garage. If so, do you have any advice and did you compare the cost with a more traditional construction method?

Rather than calling it a garage, perhaps I should have called it a house for my car. I want airtight, warm and energy efficient. Windows and doors will be of a similar level of energy efficiency.

Not sure about the fire argument. I’m not going to be doing anything more flammable than I would do in the house and if my car decides to spontaneously combust a wooden roof will go up just as quickly as some SIPS panels.

I’ll try and find this other thread you mention. Sounds like there might be some good info there.

Now that’s a good answer. Thank you. I wanted to reduce build time because I hate the mess. However, the downsides you mention outweigh the benefit of reducing the build time so I think I’ll have to go with cavity walls and some nice cladding.

As an aside, I think I have found some wooden bifold garage doors with built in insulation. I still need to check how well they’re sealed but given the price I reckon they’ll be ok. Oddly though, you’d think the bifold door companies would all offer insulated garage doors as well. Seems to me to be a straightforward extension of what they already offer.

The old garage is half single skin brick and half single skin timber with old crittle windows. Zero insulation. My wife has a little craft hobby room in the back. In the winter it is so cold and damp she has to stand next to an oil filled radiator and an electric fan. Even then it is often too cold and she has to come into the house to warm up. I can’t see how we can even begin to make it warn enough to use in the winter hence a completely new building.

Very interesting. How did you get on through the winter? Was it not flippin’ freezing?
