We are proud to introduce ISOGARD AK: a polyisocyanurate (PIR) insulation board specifically engineered for flat roof systems. It consists of a closed-cell PIR foam core laminated on both sides to a gastight multi-layered aluminum-kraft complex facer. Boards are available with straight and rebate edges.
The unique foam and facer technology of ISOGARD AK gives it long-lasting and stable performance, outstanding thermal and dimensional stability, as well as high compressive strength.
ISOGARD AK is suitable for all flat roofing systems, including those where the demands on PIR board application are very high, such as fully adhered EPDM roofing systems.
ISOGARD AK boards have been carefully formulated to remain stable, even at very high roof surface temperatures.
The microcell structure of ISOGARD AK makes it dimensionally stable under harsh roofing conditions.
HIGH COMPRESSIVE STRENGTH
ISOGARD AK boards do not get soft or compressed during or after installation.
ISOGARD AK boards offer good walkability and resistance to dynamic loads.
SUPERIOR THERMAL PERFORMANCE
ISOGARD AK offers the same thermal performance as thicker and/or heavier insulation materials.
If installed correctly, ISOGARD AK will last for the lifetime of the building.
ROOFING SYSTEM COMPATIBILITY
Lightweight and easy to install, ISOGARD AK boards are compatible with most roofing membranes and systems. They can be used over plywood, concrete and metal roof decks, both on new-build and refurbishment projects.
PIR boards are one of the most sustainable roof insulation choices available today, saving more than 100 times the energy it is used to produce them. ISOGARD AK’s foam technology uses a HCFC-free blowing agent with a low Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP).
ISOGARD AK boards can be installed using fasteners and plates or approved insulation adhesives. They must be protected from moisture during storage and until the roofing membrane is installed.
Substrates must be dry, smooth, level, free from contamination and sufficiently strong to fix the roof build-up. Acceptable types of roof deck are in-situ poured concrete, pre-cast concrete elements with and without pressure layer (screed), lightweight concrete slabs, profiled metal decks, sandwich panels and wooden decks (timber, plywood, OSB).
