Drylining and dampness

A country home

soon building as i mentioned before, and this is what i had planned..

100mm cavity with say 70-80mm kinspan

and 25mm dryline on exterior walls in the inside.

My concern is that i have seen the words mold/dampness/dryline all in the same sentence a few places on the forum.

Can i have some claification as to what problems are, and how to solve them or more importantly how to prevent them. . . . .

Firstly you should have a 40mm cavity so 80mm insulation = 120mm cavity. A lot of the posts you have read regarding drylining / dampness / mould refer to old buildings with solid stone walls which are intended to breathe, you are constructiing a new cavity wall so I would have no problem with what you are doing. I would however at least scratch coat the inner leaf before drylining for airtightness. I have used a similar build up on a number of houses and they have all turned out to be very warm and cosy.:D

you are a life saver. . well a house saver. I just told the raft engineer guy that the cavity was 100, but that i wanted 75-80 insulation in the cavity. . and he said nothing. . :rolleyes:.. . as usual. .
then i came home and looked the at spec my builder done and he spec'd 75mm insulation in a 115mm cavity.. . . so you and him are in the same frame of mind. . .

I will be asking you a few questions in relation to DL in the coming months. .

I may also ask, is there such thing as bad/useless 75mm insulation in the wall. . my builder hasnt spec'd any particular type. .

I will of course say it to him. .

OP,
Perhaps you should hire aprofessional to oversee your build.
One mistake or mis-communication could cost more than the cost of a professional.
