Professional installers highly favor Eurothane® GP 80mm insulation boards due to their lightweight design, ease of installation, and ability to be efficiently cut on site. When laying the boards, it is recommended to align the long edges parallel to the rafters and tightly butt them together in a brick-bond pattern. For board joints running from eaves-to-ridge, it is crucial to support them with rafters. Before counter battening, boards can be temporarily fixed with nails.
The 80mm PIR insulation boards are fitted in a tightly butted brick-bond pattern between the framed wall battens.
When installing the Eurothane boards, they should be laid in a tightly butted brick-bond pattern. If the desired insulation thickness requires two layers, it is essential to stagger the board joints and position the thicker layer on the outermost side.
Our 80mm Insulation is manufactured to the highest standards, making the installation process significantly easier. With precision cut straight edges, consistent board sizes, high compressive strength, and a super-flat surface finish, our boards provide a quicker, easier, and more cost-effective installation. For a trouble-free, perfect build, trust Recticel PIR insulation.
Selecting the appropriate ground Floor Insulation requires consideration of both thermal and mechanical properties. Recticel 80mm PIR is an excellent choice for both domestic and commercial buildings, providing the required low thermal conductivity and high compressive strength for various floor constructions. As underfloor heating remains a popular feature in modern flooring, Recticel PIR excellent pipe clip retention makes it the perfect option.
Recticel's PIR insulation is not limited to ground applications. Eurothane FP is an excellent choice for lining the soffit of an intermediate floor above a basement or car park, providing the same exceptional thermal performance combined with a Class 0 spread of flame rating.
