140mm Kingspan GreenGuard GG300 XPS Board is an insulation for inverted roofs, basements, car park decks, and heavy-duty commercial, industrial and cold store flooring. They have high compressive strength, and a closed cell structure which resists the absorption of ground water and the passage of water vapour. The board has a closed cell structure, which makes it water vapour and moisture resistant, and is also unaffected by air filtration, thus upgrading the thermal performance of the entire construction.
