They are widely used for insulation, ventilation and the adjustment of air-conditioner in commercial industry and residential constructions.

Meanwhile, they have the effect of energy-saving insulating, sound-controlling and improving the indoor air quality.

Glass wool building blanket is manufactured in custom sizes. It is used on the slabs of non utilized attics, betweenthe rafters of utilized attics, for horizontal applications where no load isapplied, for metal and sandwich roofs.

Installation and use

Building blankets are rolled out on the slab when they are used for the insulation of non utilized attics.

If can be applied easily with no waste pieces and each piece can be utilized. It can be adjusted to any type of roof. In order to reduce the condensation risk in winter and to discharge the overheated air in the attic, upper part of the insulation should be kept ventilated. The rolls should not be covered over by

nylon or similar type of covers. Aluminium foil faced building blankets should be rolled on in the manner that the foiled face will be on the heated side.
