Hi,
I'm planning on using SIPs as the build system for our Self Build (If I manage to find a plot!) but I see that there are a lot of options on what to combine SIPs with. For example, SIP and Brick, SIP and Block & Render, SIP and Cementboard & Render etc.
We probably want a render finish, so that gives us the choice of block and render or cementboard and render for the outer walls, but I've seen very little comparing these options.
The obvious points are:
Cementboard and render is going to be a lot thinner than block and render
Presumably cementboard will be a lot quicker than building a block wall?
Presumably cementboard is cheaper (Both in terms of purchase costs and fitting costs)?
But what are the downsides? i.e. why would anyone choose block and render over cementboard and render?
Cementboard is obviously a lot thinner than blocks, so does this have any effect on thermal performance? If so then presumably having thinner walls would allow me to have thicker SIPs panels, which would hopefully more than compensate?
Thanks in advance
Ben
