Storage Conditions

The recyclable packaging for Eco Inverted Roof Board should not be considered adequate for long term outside protection. Ideally boards should be stored inside a building.  Eco Inverted Roof Board should be stored flat in ventilated areas and protected generally from accidental damage, contact with volatile solvents, flames and extended exposure to UV and sunlight.  If stored outside for more than a few weeks, boards/packs must be covered with a pale pigmented plastic sheet. Eco Inverted Roof Board should not be left in the sun, covered by either a transparent or a dark plastic sheet, since in both cases, board temperatures can build up to a level hot enough to appreciably alter their dimensions or warp them.
