Why Some Homes Are Hard to Heat Some homes seem difficult to keep warm no matter how long the heating is left on. One room may always feel colder than the others, the heating may appear to run constantly, or the house may cool down very quickly once the heating switches off. The obvious reaction […]
Loft Insulation
Loft Insulation Why the roof is one of the first places to look when a home is losing heat Heat naturally rises.

Home Age Identification
How British homes changed — and what that means for insulation The age of a property can tell you a great deal about how it may have been built. A Victorian terrace, a 1930s semi-detached house, a post-war system-built home and a modern low-energy property can all look like “normal houses” from the outside, but […]
Condensation vs Damps
Condensation vs Penetrating Damp vs Rising Damp How to tell the difference before blaming insulation A damp patch on a wall can have several completely different causes.

About Air Bricks and Suspended Floors
Air Bricks and Suspended Timber Floors How existing ventilation is protected during cavity wall insulation Air bricks play an important role in many traditionally constructed homes, particularly properties with suspended timber ground floors. Their purpose is to allow outside air to pass beneath the floorboards and ventilate the underfloor void. This helps control moisture levels […]
