Loft insulation (merged threads)

The pros make up a container out of plastic sheet to fit the hatch and the water tanks and fill it with insulation and they fit draght excluder around the outside of the hatch. The type with bristles on so that the lid sits on it when closed.

Hi duncan32

Yes one full day should do it. I bought the rolls a week before and stored them. Then on the day I pushed them through the hatch one at a time. Don't forget a face mask, goggles and gloves, oh and make sure you have no skin exposed, it can itch. Have a shower or bath afterwards and reward yourself for a job well done. True money saving.

my house is 50 year old, my gas bill came in and it shocked me so i need to save some heat, i just bought the house last year and not had time to do any energy saving things.

The loft is spacious and floored in the main area, there is only 1" of insulation material. Do i just buy insulation for whatever thickness of joists i have ie 200mm, is it a bad idea buying thicker and compressing it as i will need to relay the floorboard.
The areas not covered by floorboard should i lay a double layer?

It looks pretty straight forward but i have never done it but i just thought i should ask before i buy the lagging.

The main area of my loft is floor boarded too. Before the insulation was laid I increased the size of the joists by screwing 4"x2" on top to allow for the extra depth of the insulation.
To get the max benefit you need to use 10" of insulation and I found with the extra on the joists mine was around 9" so not much compression. Too much compression and you lose the benefit.

Hi, just a thought, if you only have an inch of insulation you could be eligible for a grant towards the cost of the insulation, its worth checking before spashing out.
