Over Rafter Thermal Insulation

For the purpose of this installation: a rafter is defined as a simply supported timber beam with its ends prevented from lateral movement and torsional rotation about its longitudinal axis.

One of the most cost-effective insulated ceilings is to install IsoBoard as a roof-liner over trusses, beams and rafters.

The board, in addition to providing high levels of thermal insulation, provides a beautiful backdrop to exposed trusses, and can be painted to match as required.

Typical uses for IsoBoard in this application

Used as a ceiling in domestic homes (affordable and up-market) over exposed rafters.
