Hi,
We've fitted a fully glazed floor to ceiling porch on the house and no want to fit a new front door which is now inside the porch obviously. We like the design of some internal doors - veneered oak planking styl
- to get the same design in external door spec is several hundreds o pounds more. The question is, can we use the internal door version and comply wit building regs (door thickness would be 34mm'ish not 44mm as existin door), insurance etc. Is the only reason external doors 44mm is insulation value? or is i something more?
Cheers Jo
