Is it possible to have MVHR fitted to a new self build if you have an attached/internal garage?
If so how do you get a good seal on the fire door separating the house & garage. The garage would have 50mm cavity wall insulation and would have a 60mm insulated door but these still pass air. The room wouldn't be fitted with any supply or extract vents from the MVHR.
I struggle to find any internal decent door sealing systems in the uk, but when I've visited Austria they have excellent seals between internal doors with a triple rebait and a rubber seal fit into a groove.
