What’s the point of paying to heat your home and then losing the heat through poorly insulated walls? Not only does it waste your money but it wastes energy and increases your carbon emissions.

House insulation is an essential part of the deep retrofit process. In a home energy retrofit, the aim is to identify all areas where your house is losing energy and then rectify them. You could be losing energy through insufficient or poor quality insulation in the roof, walls or floor.

As part of our energy audit, we’ll identify where and why your insulation is inefficient and create a bespoke solution to fix the problem, adding or replacing insulation wherever your particular house needs it, in a way that suits your needs. We offer:

  • External, internal & cavity wall insulation
  • Insulation for attic ceilings, pitched roofs and flat roofs –
  • Insulation for concrete or timber floors

Whilst we offer the full range of available insulation products, which one we recommend will depend on the results of your home audit. The suitability of products depends on how your house was constructed.

Often we require a solution using a number of different types of insulation. It sounds complicated, but don’t worry, we’ll make it simple for you!

FREQUENTLY ASKED QUESTIONS ABOUT HOUSE INSULATION

The insulation in my attic is very thin, but if I add more it will rise above the joists – do you have a solution for this?2020-07-14T22:21:46+01:00

This is normal. There is usually 100mm (4 inches) or 150mm (6 inches) of insulation in place. If the existing insulation between the timbers is good enough, it is normally left in place. If not, it is removed and replaced. Additional is rolled on top between the timbers and then across the timbers as required, at 90 degrees to the layers below to provide better coverage. We normally increase the depth of attic insulation to 400mm (15¾ inches). If a floored area for storage is required in the attic we counter batten to raise the new floor area above the new insulation level.

My friend had external insulation installed and there was a choice of finish and colour – what finishes/colours do you offer?2020-07-14T22:20:27+01:00

Depending on the finish coat specification there are hundreds of colours, as well as slip brick and other finishes. Some colours have longer lead times of 4 to 6 weeks but the most popular colours are normally readily available.

Does your insulation help to reduce noise levels from outside/our neighbours?2020-07-14T22:19:39+01:00

It depends on the type and amount of insulation used. It will make some difference, especially when combined with new double glazing it will. New triple glazing will make a noticeable difference when combined with air tightness measures.

What impact will new insulation have on my BER / carbon footprint?2020-07-14T22:18:35+01:00

This is a difficult question to answer. It really depends on how much you’ve upgraded, the level of insulation and the number of BER levels the house is raised by. Take a look at the chart below and this will give you some idea of the impact of your work on emissions.

How soon can the job be done after I call/have a consultation?2020-07-14T22:16:25+01:00

This depends whether there is a grant involved and if so, which grant, and which process is used.

Under the Better Energy Homes (BEH) it could be a week or two, under the Better Energy Communities (BEC) it could be a few months or a year.

It also depends on your preferred time line and our work schedule.

Extensive deep retrofits can require people to move out of the house for a month or two.

How do you deal with existing damp issues?2020-07-14T22:15:24+01:00

Establish (if possible) the cause of the moisture source and fix the problem.

Normally this is quite straight-forward. However, sometimes this may require invasive work to determine the cause as the source of the moisture can be remote to where it is appearing.

I have a problem with damp – can you fix this when you’re installing new insulation?2020-07-14T22:14:41+01:00

Under the grant regulations, we are not allowed to make any repairs to houses to make the house insulation ready as part of the grant works. Of course, the repairs are necessary, so we can address this as part of a larger works package, or separately outside of the grant works.

Which type of insulation is suitable for my house?2020-07-14T22:13:39+01:00

It depends on how the house is constructed and how you want it to look afterwards.

While there are similarities in house typologies, every house needs a custom solution.
