The method of insulating a pitched roof is particularly suited to loft conversions and refurbishment where the rafter depth is insufficient to accommodate the thickness of insulation required whilst providing a 50mm ventilation void (a requirement of the Building Regulations/ Standards for 'cold roofs').
This option is preferable to insulating only between the rafters (provided there is sufficient head room to accommodate the insulation) as it limits the cold bridge effect through the rafters. For this application we would recommend the use of Seconds between the rafters and Seconds beneath the rafters.
