Hi all,
I recently followed some great advice on this forum to insulate my suspended ground floor. Awful job, but in completion the amount of difference it's made has been incredible. Off the back of that I've decided to look at what else I can insulate to further increase the thermal efficiency of this property.
So the next place I wanted to look properly at was the loft space on the top floor. The property does already have 3 rooms situated together toward the middle of the top floor, and the loft space surrounds them at the edges of the top floor... if that makes sense.
I noticed in the loft space it already has a good deal of insulation on between the floor joists as shown on the picture below. But also noticed the voids between the roof joists are without insulation. Am I correct to assume this can and should be insulated?
One other thing I noticed was at the far edges of the loft space, I can see daylight and a considerable draft coming through up through the vents in the eaves, see video and photos below.
Is there anything I need to be aware of with regards to insulating the roof joists when considering these eaves vents? Also do I have any options to insulate those drafts in the eaves? I can appreciate why they shouldn't ever be blocked, but sort it's got me thinking that even if I insulate the void between the roof joists....the cold air from the eaves vents will be coming up below them anyway and I guess massively negating any benefit i'd see by insulating said roof joist voids?
Video will explain better - Loft and eaves Video
thanks very much,
