I have started to build a bungalow and have a standard cavity with 60mm kingspan boards in the cavity. I have decided to install a HRV system and in order to make my masonry build as air-tight as possible I am looking at different methods.
I came across an article recently on Construct Ireland where they recommended the use of blown-in beads as a method of improving the air-tightness of the building. It seems like this would help as it reduces the amount of air that can flow in the cavity and should also have the added benefit of improving the insulation. Is there any draw backs or problems to using the blown-in bead combined with the Kingspan boards?
Also, I have drylining boards on all the external walls of the house. My understanding is that these will be fixed to the wall using daubs. I have also read that applying a wet plaster finish is a good method of achieving air-tightness. Is it standard practice to have a scratch plaster finish on the wall before putting on the drylining boads or is this something I would need to ensure the builder does?
