I have debated installing loft insulation......
My house is a 4 bed detached and i pay £100 per month for gas and electric. Joists are 70mm so putting insulation in between joists is futile and impossible as thinnest width i can find is 100mm. And i am not stupid enough to start raising boarding etc....no way mate!
Currently there is a very thin layer on underside of felt. I have contemplated topping up the rafters (90mm) with insulation. The scare mongerers waffle on about a 50mm ventilation gap. 'If you dont do it, you will be plaugued with condensationit will be raining in the loft........how....why????
What is the difference, these vast molecules and gallons of water cant escape today as the felt is non permeable...so where does it go? I imagine, through the eaves - along with all my heat! So, if i insulate the rafters...what will change...the gallons of water per day will vent through the eaves and so will my heating continue to do so! Why should i get condensation - this is totally illogical - the felt is non permeable - the insulation doesnt change this!
My neighbour who has an identical house has followed the regs and applied insulation to 300mm thickness (more than the 270 defined by regs). His monthly gas/electric bill has not changed (he installed the insulation 2 years ago) and is as much as mine! Also, on a frosty, snowy morning his snow clears at the same time as mine - literally within the hour! Surely, thats enough to tell us its a BIG CON! But i did see 4 pigeons on my roof when it last snowed while the neighbours roof was vacant....they were toasting marshmallows....
I am still intrigued to hear how the wool causes condensation if installed along rafters. I think some people LOVE to over think things!!!! Makes them sound clever.....
