Permastop® is ideal for use under metal roofs to provide thermal and acoustic comfort and condensation control. Permastop reduces the amount of heat entering your attic space working in tandem with ceiling insulation.

Stop Excessive Noise

Metal roofs are becoming ever more popular with Australian homes. The sounds of gentle rain on a metal roof can be music to the ears, however it's when the sounds of heavy rain or even hail reaches defening levels that they can be noisy and uncomfortable.

Permastop is an insulation blanket that is fixed directly under the metal roof and is effective in reducing the noise levels entering your home from rain, hail, aircraft and other outside noises.

75mm Permastop can reduce sound transmission through the roof by up to 18dB.

Prevent heating & cooling loss

Permastop has the added benefit of providing your home with proven thermal insulation to give you energy savings and make your home even more comfortable.

Permastop used in conjunction with Pink Batts® in the ceiling will give you even more effective insulation performance.

Permastop under your metal roof, used with Pink Batts in your ceiling and walls will help make your home cooler in summer and warmer in winter. Insulation is one of the most cost effective building materials you can use to reduce your energy bills. Combined with common sense design elements like shading windows from summer sun and weather stripping doors and windows, you will make your home more comfortable and reduce the need to pay for artifical heating and cooling.

Stop condensation in ceilings

Permastop is made with Sisalation® reflective foil facing on one side. This combination acts as an effective barrier against condensation forming on the underside of your metal roof. Especially when warm, moist air is vented into the roof space from bathroom and kitchen fans and vented range hoods.
