HIRSCH Isolation offers the first solution for insulation and drainage of buried walls in graphite expanded polystyrene

Intended for external thermal insulation (ETI) of basements and buried walls (excluding linings), Cellodrain® Ultra is a 3-in-1 solution :

• Thermal insulation : thanks to the qualities of graphite expanded polystyrene, Cellodrain® Ultra benefits from excellent thermal performance (lambda λ of 0.031 W/(mK)) and allows very high thermal resistances to be achieved, up to 6,45 m².K/W, by limiting thicknesses;
• Stormwater drainage : with a lug surface protected by a geotextile, Cellodrain® Ultra ensures an efficient drainage function;
• Waterproofing protection : the 4-sided rebated edges of the panels provide optimal protection for the waterproofing of the support.

  Cellodrain® Ultra & Cellocem® Ultra: a comprehensive solution for basement walls   To ensure perfect continuity of thermal insulation from buried walls to exterior insulation of facades, HIRSCH Insulation offers a ready-to-use solution with Cellocem® Ultra panels. The only insulation and base protection complex fully ACERMI certified (insulation + cladding), Cellocem® Ultra combines graphite expanded polystyrene insulation and cement board cladding. Completely rot-proof, Cellocem® Ultra panels provide insulation and mechanical protection in a single operation! The combination of Cellodrain® Ultra partially buried and Cellocem® Ultra in the basement provides an optimal solution for insulating and protecting buildings. Made in France, Cellocem® Ultra is compatible with passive buildings and BEPOS.
