Thermal Linings

A high performance insulation solution comprising a PIR foam with a kraft paper/aluminium multi-layer finish, factory bonded to a 12.5mm tapered edge plasterboard offered in a board size of 1.2m x 2.4m.  The foam has a very low thermal conductivity (k) of 0.022W/mK with the plasterboard providing an optimum thermal insulation solution.

Speedline Thermal Laminate Board is a versatile insulation and dry lining solution which may be installed in a variety of locations within a building.  The following details are intended to provide an indication of both application and achieved performance within the noted construction build-up.

Solid Masonry Walls: Mechanically fix onto Timber Battens
The U Value calculation is based upon a solid 215mm masonry wall with Speedline Thermal Laminate Board being mechanically fixed into timber battens.
