How to insulate Pitched Roofs with Eurothane® GP?

Installers prefer Eurothane® GP 20mm boards for their lightweight nature, simple cutting on site, and straightforward installation. Position boards with long edges parallel to rafters, butting them tightly in a brick-bond arrangement. Support board joints that run from eaves-to-ridge with rafters. Temporary nailing secures boards before counter battening.

How to insulate Framed Walls with Eurothane® GP?

Fit the 20mm PIR boards in a tightly butted brick-bond pattern between framed wall battens for consistent thermal coverage.

How to insulate floors with Eurothane® GP?

Lay boards in a tightly butted brick-bond pattern. When two layers are required for greater thickness, stagger the board joints and position the thicker layer on the outer side.

Recticel PIR The Advantages

Our 20mm Insulation meets rigorous manufacturing standards, streamlining installation. Precision-cut straight edges, uniform board dimensions, high compressive strength, and a flat surface finish combine for faster, simpler, and more economical installation. Recticel PIR delivers a reliable, quality build.

Floor Advantages

Choosing the right ground Floor Insulation requires balancing thermal and mechanical performance. Recticel 20mm PIR suits domestic and commercial applications, delivering the low thermal conductivity and high compressive strength needed for diverse floor systems. Since underfloor heating is standard in contemporary flooring, Recticel PIR's excellent pipe clip retention makes it an ideal solution.

Recticel's PIR insulation extends beyond ground applications. Eurothane FP works well for soffit lining on intermediate floors above basements or car parks, combining outstanding thermal performance with a Class 0 spread of flame rating.
