I meant Guy Williams, but it equally applies to both.
I'm up for a set, please, John.
I'll wait and see if any others want some before getting any made. I
assume as yours is still in the box you're not quite ready for them
yet. Send me a reminder if you have'nt heard from me when you start.
The architect member of our group was adamant that
NO waterproof membrane should be put behind the softboard and that
the gap under the felt should be left so that air can circulate;
My loft floor in my c1988 house has 8x2 joists and no trusses (its why
I wanted the house!) There is currently about 4" insulation under the
chipboard floor. I am supplementing this around the edges to bring it
up to 8" and to trap any heat loss to the middle of the floor. I am
then using a special foil bubble wrap insulation which is designed for
this purpose on the inside of the rafters. This leaves a substantial
air gap between it and the tiles/felt which goes all the way from the
soffit to the ridge. This will leave the area inside the insulation
slightly warmed (due to loss from the 4" insul.) but it will keep out
all the drafts from the soffit gap. Note I also have a velux window
and ventilation from the inside area, and the water tank is still
warmed from below. I'm only 1/4 way through but my wife already says
our bedroom is warmer!
