Polystyrene Roof Board

Features

• ROOF GUARD is a thermal insulating board that can be used for both “inverted-system” as well as “conventional-system”. INVERTED ROOF SYSTEM: This system became standard and proved its usefulness over the period of time. Many consultants, contractors and architects prefer and recommend this system as it has many advantages over conventional system. The concept of this system is the roofing membrane is laid directly on to the roof deck followed by roof guard boards as an insulating layer, then separation layer laid over it, and the final layer can be gravel or paving slabs or tiles. ADVANTAGES OF INVERTED ROOF SYSTEM. The water proofing membrane is protected from the various effects of weather and mechanical stresses occurring during construction which increase membrane life. The inverted roof system reduces the maintenance cost of the roof. INSTALLATION RECOMMENDATIONS: The concrete deck should be clean and smooth if it is rough it is advisable to install protection sheet underneath the membrane. The water proofing membrane should be of good quality and free of solvents which could attack XPS foam and could be laid directly on concrete deck. In next stage the XPS insulation boards should be laid loosely over the membrane with tight staggered joints. Paving slabs or gravels should be laid loosely over the XPS insulation boards.
