Objectives
Tackling miscellaneous holes and inappropriate obsolete vents. Our homes are have become perforated with many inappropriate and unwanted holes. Understanding and controlling air ingress/egress is paramount to home improvement. Air bricks and chimneys are problematic. Chimney stacks date back only five hundred years, the air brick a mere two hundred.
Cross ventilation and stratification.
If it can’t get in – it can’t get out.
Start with the large to expose the small.
Interventions
Foam applicator gun
Expanding foam filler is an invaluable material for sealing up draughts and a versatile adhesive for securing things in place without the need for mechanical fixings such as screws and nails. Foam filler is ideal for preventing air ingress, it is a good insulator, preventing the conduction of heat and also preventing moisture vapour migrating to cold surfaces causing condensation.
Unlike disposable canisters, a foam applicator gun provides full control. The application can be in moderate and the canister can be closed off and reused on another occasion to avoid waste.

Caulk
Decorators caulk is an affordable and easy way to prevent air ingress up from between the floorboards. Using the trigger gun the gaps are filled, being water-soluble, excess decorators caulk can be wiped away with a sponge and any residue remaining on the boards can be lifted with WD40, an oily rag, once the caulk has cured.
A box of twelve tubes is sufficient for a couple of rooms for a little over a pound per tube.
