Upgrade Insulation in suspended floors, ceilings and external walls.

[thetdog666]

Hello Folks,

 

Going to be doing up my living room(4.16m x 6.02m), dining room(3.42m x 2.41m) and kitchen(5.99m x 3.38m) and do you think it is worth while taking up floor boards, removing plasterboard in ceiling and from external walls ( about 25m in total) and putting in PIR insulation? Currently there is 100mm glass wool in the walls and under floor(held up with wire netting) and zero insulation between the ground floor and first floor. The house is about 30yo.  The floor joists are 90mm in depth.

 

This would be the best time to do it before doing the place up. 

 

Thanks

That would only have insulation as sound proofing not other reason.

 

You may need to let us know your wall construction etc.

 

You really need to start with some basics information and look at the benefits of what you are doing. 

 

You already insulation which is a start. 

 

One of the biggest heat losses is uncontrolled drafts, they are generate cheapest thing to fix.

My house is a timber framed with cavity wall insulation. Iv recently renewed all my windows and doors for new pvc double glazing. I do have an infrared thermal imager that I will have a look in the winter with for draughts. Im not sure how effective the insulation is under the floor due to it just being netting.
