1. Missing insulation in the loft

Sounds obvious perhaps? But it's not usually the main loft - if your house has different sections of roof and you can't access everywhere from the loft hatch, chances are the guy putting in the insulation couldn't either! For whatever reason, sections of ceilings in these inaccessible areas are surprisingly often left uninsulated. The first thing the occupant notices is "the front bedroom is very cold", "loses temperature quickly", "hard to heat." Putting in larger radiators seems to be a solution offered up, but that's not solving the problem.

Thermal imaging can detect cold spots on the ceilings, and from the shape, location and temperature difference, your experienced thermographer can determine the likely cause.

So if this fits with what you are experiencing, take action.

2. Poor air tightness, creating draughts

Changes to Building Regulations should mean that this becomes less of an issue, but unwanted air flow can still result in a rapid cooling of a house once the heating has been switched off. Classic leaky spots are around pipework in en-suites, under baths, under kitchen units and around boiler flues, but can also exist at floor to skirting junctions etc. Too often the windows get the blame, so instead check around the window frame, where it meets the wall - that's where many of the problem areas at windows are. Our air test using smoke pencil and/or thermography will highlight all these problems for you.

3. Air flow within the walls and ceiling

If your house is significantly colder on windy days then this could be your problem. Particularly in timber frame houses, and particularly if you live in an exposed part of the country, cold wind driven air if forced in through soffit vents and under and through insulation in ceilings and walls. This significantly reduces the effectiveness of the insulation, and increases the effective u value and decreases the r value of insulation. So if your house is normally nice and cosy but doesn't like the wind, read on.

Again an experienced thermographer can look at the patterns and advise the likely cause.Whatever the problem, house builders and NHBC can make use of our images and reports to make good any issues covered under warranty. If not, we can advise you and your contractor (or ours) on steps to take to stop your house leaking heat.
