Barn roofs can be insulated by fitting a new breathable membrane above the rafters. Rigid board or mineral fibre is fitted between the rafters, and TLX Silver below rafter. A batten and plasterboard completes the roof construction. This method conceals the rafters, but purlins may be left exposed.

Solutions with mineral wool: TLX Silver BM Wool


If the rafters are to be left exposed, then insulation must be installed above the rafters. A good solution is to board above the rafters, install rigid board and then TLX Gold as a 2-in-1 insulating breather membrane.
