How to insulate Pitched Roofs with Eurothane® GP?

Installers favour the 140mm boards for their low weight, straightforward fixing, and site-cutting capability. Position boards with long edges running parallel to roof rafters, pressing them firmly together in a staggered brick-bond arrangement. Where joints run from eaves to ridge, ensure rafter support is in place. Temporary nail fixings work well before counter battening is applied.

How to insulate Framed Walls with Eurothane® GP?

Install the 140mm PIR boards between wall frame members in a tightly butted brick-bond pattern for optimal thermal performance and structural stability.

How to insulate floors with Eurothane® GP?

Lay boards in a tightly butted brick-bond pattern across the floor structure. For applications requiring two insulation layers, stagger the board joints and position the thicker layer facing outward to maximise thermal resistance.

Recticel PIR The Advantages

Recticel manufactures this board to exacting standards, streamlining the installation process considerably. Precision-cut edges, uniform board dimensions, robust compressive strength, and a consistently flat surface all contribute to faster, simpler, and more economical installation. Choose Recticel PIR insulation for dependable, high-quality building performance.

Floor Advantages

Selecting ground Floor Insulation requires balancing thermal and mechanical requirements. Recticel 140mm PIR delivers both low thermal conductivity and high compressive strength, making it suitable for domestic and commercial floor constructions. The material's excellent retention properties for heating pipes make it particularly well-suited to underfloor heating installations.

Recticel's PIR insulation extends beyond ground-level applications. Eurothane FP provides an ideal solution for intermediate floor soffits above basements or car parks, combining exceptional thermal performance with Class 0 fire rating.
