Specialists favour 90mm Eurothane® GP boards for their light weight, straightforward installation, and on-site cuttability. Position boards with long edges running parallel to rafters, pressing them tightly in a brick-bond arrangement. Support board joints that run from eaves to ridge using rafters. Temporary nailing can secure boards before counter battening is applied.
Install 90mm PIR boards between wall battens in a tightly butted brick-bond formation.
Lay Eurothane boards in a tightly butted brick-bond pattern. When two layers are needed for greater thickness, stagger the joints and position the thicker layer facing outward.
This 90mm Insulation meets rigorous manufacturing standards, streamlining installation. Featuring precisely cut straight edges, uniform board dimensions, robust compressive strength, and a level surface, boards deliver faster, simpler, and more economical fitting. Depend on Recticel PIR for dependable, quality construction.
Choosing suitable ground Floor Insulation demands attention to thermal and structural characteristics. Recticel 90mm PIR suits both residential and commercial projects, delivering the necessary low thermal conductivity and high compressive strength across diverse floor designs. Since underfloor heating features prominently in contemporary flooring, Recticel PIR's superior pipe clip retention makes it an ideal solution.
Recticel's PIR insulation extends beyond ground-level use. Eurothane FP works excellently for intermediate floor soffits above basements or car parks, combining outstanding thermal performance with Class 0 flame spread classification.
