Installers consistently choose Eurothane® GP 50mm boards for their light weight, simple fitting process, and on-site cuttability. Position boards with long edges running parallel to rafters, pressing them firmly together in a staggered brick pattern. Ensure board joints extending from eaves to ridge are supported by rafters. Temporary fixings with nails may be applied before counter battening.
Install 50mm PIR boards in a firmly butted staggered brick pattern between wall frame timbers.
Lay Eurothane boards in a firmly butted staggered brick arrangement. Where two layers are needed for desired thickness, offset the board joints and position the thicker layer on the outer face.
Our 50mm Insulation meets the highest manufacturing standards, streamlining the installation experience. Featuring precisely cut square edges, uniform board dimensions, robust compressive strength, and a level surface finish, our boards deliver faster, simpler, and more economical fitting. Select Recticel PIR insulation for dependable, quality construction.
Choosing appropriate ground Floor Insulation involves evaluating thermal and structural properties. Recticel 50mm PIR excels in residential and commercial settings, delivering the necessary low thermal conductivity and strong compressive strength for diverse floor builds. Since underfloor heating features prominently in contemporary flooring, Recticel PIR's superior pipe clip retention capability makes it an ideal solution.
Recticel's PIR insulation extends beyond ground-level applications. Eurothane FP serves as an excellent option for intermediate floor soffits above basements or car parks, combining outstanding thermal performance with a Class 0 spread of flame rating.
