Cold floors in a Greenbank house, sorted with insulation between the joists and an Intello Plus airtight membrane laid over the top before the new flooring went down.
A house in Greenbank with cold, draughty ground floors. With the old floor up, we insulated between the joists and then sealed the whole floor before new boards went down.
Insulation fitted between every joist, supported from below so it stays in place and in full contact.
Intello Plus laid across the joists and taped at the edges and joins. It stops the draughts coming up through the floor while still letting the timbers breathe.
Chipboard flooring laid and fixed over the membrane, ready for the finished floor.
Membrane sealed at the wall, new boards going down.
Most cold floors are as much about draughts as insulation. Air comes up between the boards and through gaps at the skirting. Sealing the floor with an airtight membrane is what stops that, and it's the step that usually gets missed. Underfloor insulation in Edinburgh
