Sorry if this query has been asked before but I cannot find a suitable answer.
I am getting quotes for a loft storage room. Basically boarding floor, eaves storage, velux and plasterboard roof. All quotes unfortnately differ dramatically in what and how they propose to do.
My query is about insulation between the plasterboard on the roof. One company has said they will use solarguard (multi layered protective quilt). The other quote will use standard fibreglass insulation.
Can someone tell me whether the fibreglass will give suitable ventilation to the roof. The company using the solraguard will put airflow collars and battens. the company using the fibregass will not.
I might add the company using the solarguard will be complying with Part L1B and the other will not.
any replies greatly appreciated
