Resista MG is a high-performance polyisocyanurate (PIR) insulation board specifically designed for residential flat roof systems. Featuring a closed-cell PIR foam core laminated on both sides with mineral-coated fiberglass facers, it offers superior thermal insulation, compressive strength, and long-term dimensional stability. Optimized for full compatibility with RubberCover™ EPDM membranes, Resista MG delivers reliable, energy-efficient performance for both new build and refurbishment projects.

The Resista MG Insulation Board provides exceptional performance and durability for warm flat roof constructions. Its rigid PIR core and mineral-coated fiberglass facings ensure excellent adhesion when used with fully adhered EPDM waterproofing membranes such as RubberCover EPDM.
Resista MG offers outstanding thermal efficiency while maintaining high compressive strength and resistance to moisture. Its closed-cell structure prevents water absorption, ensuring consistent long-term insulation values even under demanding weather conditions.
Lightweight and easy to install, it is suitable for new roofs and refurbishment projects, forming part of a complete warm roof system when used with RubberCover EPDM membranes and V-Gard self-adhesive AVCL (Air & Vapour Control Layer).
