Insulation is an essential part of ensuring that a building is energy efficient. It keeps the building cooler in the summer and warmer in the winter, resulting in significant savings in heating and cooling costs. Passive buildings, a construction concept that aims to minimize the building's overall ecological footprint, require proper thermal insulation as one of their key components.

Of the many insulation products available on the market, rigid polyisocyanurate (PIR) boards are among the most efficient in terms of thermal performance per millimeter. This means that a thin and lightweight PIR board can achieve an insulation value that is equivalent to other thicker, heavier insulation products.

Elevate's RESISTA AK+ insulation board is an excellent option as it consists of a closed-cell PIR foam core, laminated on both sides to a gastight aluminum multilayer complex. This product offers superior and stable thermal resistance, dimensional stability, and compressive strength, which results in long-lasting performance.

RESISTA AK+ can be installed on a variety of substrates such as wood, concrete and metal. It is also compatible with different roofing membranes and adhesives, making it suitable for use on single-ply mechanically fastened, fully adhered, or ballasted roofing systems.

RESISTA AK+ insulation boards must be installed using fasteners and plates or approved insulation adhesives or appropriate ballast. For detailed installation information, please refer to the Installation Guidelines or the Technical Information Sheets.
