How to lay loft floor insulation

How to lay loft floor insulation

Insulating the loft can seem like an unappealing job, but saving money on your utility bills always sounds good. If your home’s without loft insulation, you could be losing up to a quarter of your home’s heat through your roof*. This makes insulating your loft one of the most effective ways to reduce heating bills and be more energy-efficient. And even if you already have some existing insulation, it’s key to have the optimum amount for it to be truly effective.

In this guide, we’ll walk you through everything you need to know to lay loft floor insulation. Also known as ‘cold roof’ insulation, insulation is fitted to the floor of the loft trapping the heat in the main part of the house and away from the loft. This is ideal if you don’t use your loft at all, or only for the storage of non-perishable items.

The alternative is ceiling, or ‘warm roof’ insulation. This is fitted above the rafters and keeps the heat in the loft. It uses different types of insulation to loft floor and is used in loft conversions to make the space into a habitable living area. This isn’t explored in this article.

Our guide includes step-by-step advice on how to:

  • Work out how much existing loft floor insulation you already have
  • Confirm how much new insulation you need
  • Lay, and cut, two different types of loft floor insulation – rolls of insulation and insulated loft floor boards
  • Lay loft floor insulation around cables and recessed downlights.

Rated 5 out of 5 by from Very messy but worth it! The boards are great, easy to cut and position but extremely messy! Make sure to wear projective equipment!

Rated 5 out of 5 by from Easy for keen DIYer Bought one full sheet to insulate ceiling bay window area of 1920's house. Suspect it had never been insulated as the room was always quite cold. Removal of plaster/latt ceiling confirmed no insulation. I cut the 100mm thick Celotex easily using a fine tooth wood saw. I did this outside as it did create a little dust (not as much as I expected and I used a dust mask). I cut it into sections to fit tightly between the joists of the ceiling. There was sufficient remaining to add another 100mm layer above, so the ceiling is now fully insulated to 200mm. I finished it off with 12.5mm plaster board skimmed. I am sure it will make a big difference in winter.

Rated 3 out of 5 by from Did the job It was squashed at the edges so 10% could not be used as planned

Rated 1 out of 5 by from Disappointed I would not recommend this product from b&q. It arrived in appalling condition. Some of the edges were broken and the silver coating was ripped and scratched in many places. I understand this might have been an isolated incident and it's only insulation board, however there should still be quality control. Customer services were not really helpful when i email the complaint and took over a week to get back to me. Will not be buying this product from here in the future.
