Loft Insulation and Ceiling Heating Systems


Late last year we were asked to install loft insulation in a house with electric ceiling heating – not a very common form of heating or one that we have worked with before.

The residents had realised that they were not only heating their bedrooms but also their loft- a huge waste of energy and money. They wanted some insulation to keep the heat in their home only, however, they were concerned about whether putting insulation on top of the heating panels could pose a potential fire risk.

Olly, our Install Manager and Julie, our Marketing Assistant and Office Manager, set about doing some research. Having contacted a number of manufacturers and suppliers of a variety of makes of ceiling heating films and panels, it was confirmed that, using our preferred product, the recommended 270 mm depth of insulation could be used safely and effectively. It should be noted that not all insulation would be suitable.

We use Knauf Earthwool which gives great thermal, acoustic and fire performance (Euroclass A1). It is:

  • Odourless
  • Rot proof
  • Non-hygroscopic (doesn’t hold on to water)
  • Will not sustain vermin
  • Will not encourage mould or fungi growth

The added benefits, which particularly fit our company ethos, are that it:

  • Contains up to 80% of recycled material
  • Uses a bio-based binder, ECOSE® Technology, which avoids the use of petrochemicals and is 70% less energy intensive than traditional binders, reducing energy consumption and CO2 emissions at the manufacturing facilities
  • Can be recycled at end of life

We went ahead and fitted the loft insulation and our customers reported an instant difference in the temperature in their bedrooms- they had to turn the heating down.

The Lifetime Savings calculator showed that they could save as much as £308 a year on their electricity bill.

You may be wondering how much all of this cost them-…it was completely FREE due to their eligibility for ECO funding.

We have recently completed another measure for them, potentially saving over £1,000 a year – but that’s another story for another time.

Please do contact us if you think we may be able to help with any insulation or other energy-reducing measures at your block.
