Insulation at rafter level in a pitched roof can create a warm, modern living space. This enhances the value and desirability of the buildings without significantly altering the building envelope.

High performance glasswool insulation at rafter level is vital for comfortable living and lower energy bills in houses and apartment buildings. Insulation prevents heat loss in winter and keeps buildings cooler in summer. The specification of high performance insulation is much more important in pitched roofs at rafter level than at ceiling level.

In many houses and apartment buildings built over the last century the roof space under the roof pitch has been often left as an unheated void. Recently many home and apartment building owners recognise the value of increased floorspace with sloping ceilings and rooflights.

• Thermo Double Roll 040
• Thermo Slab 037

Thermo Double Roll 040 - roll material. If using slabs is more convenient, then Thermo Slab 037 can be used. These materials have outstanding thermal conductivity performance (the values are specified in their names). These materials are soft and elastic; they do not crumble or break, which preserves them in the course of the transportation and the operation. This makes it possible to avoid the development of "cold joists" in the course of the operation. These materials are easy to use, can be cut easily and do not require substantial physical effort in the course of the installation. The quality of materials, their safety for health and fire safety are confirmed with the certificates of conformity, hygienic and fire safety certificate.
