How to insulate Pitched Roofs with Eurothane® GP?

Installers favour Eurothane® GP 40mm boards for their light weight, simple installation process, and ability to be cut to size on-site. Position boards with long edges running parallel to rafters, then push them tightly together in a staggered brick-bond arrangement. Where board joints run from eaves to ridge, ensure they are supported by rafters. Temporary nailing can secure boards before counter battening is applied.

How to insulate Framed Walls with Eurothane® GP?

Install the 40mm PIR boards in a tight brick-bond pattern between the timber wall frame members.

How to insulate floors with Eurothane® GP?

Lay Eurothane boards in a tightly butted brick-bond arrangement. When two layers are needed to reach target thickness, stagger the joints between layers and position the thicker layer facing outward.

Recticel PIR The Advantages

Our 40mm Insulation meets exacting manufacturing standards, streamlining the installation process. Featuring precisely cut edges, uniform board dimensions, robust compressive strength, and a level surface finish, these boards enable faster, simpler, and more economical installation. Select Recticel PIR for dependable, high-quality results.

Floor Advantages

Choosing appropriate ground Floor Insulation involves balancing thermal and structural performance. Recticel 40mm PIR delivers excellent results for residential and commercial projects, combining low thermal conductivity with high compressive strength across different floor designs. Since underfloor heating is increasingly common in contemporary buildings, Recticel PIR's superior pipe clip retention makes it an ideal solution.

Recticel's PIR insulation extends beyond ground-level applications. Eurothane FP works well for soffit lining on intermediate floors above basements or car parks, delivering matching thermal performance alongside a Class 0 spread of flame classification.
