4 where rainfall can be heavy use a fine tooth trowel to apply cold cut back asphalt mastic over the entire slab use about one gallon per 100 square feet of floor.

How to insulate a concrete roof slab.

Check out this article for a list of slab edge insulation solutions and episode 125 for my interview with henry edney of maxraft. Adding a layer of roof tiles placed directly on floor of roof which allow air to circulate under and over but keep convectional heating of the roof slab to a minimum. The basis for this simple but effective solution is natural air pressure. The best way to insulate a slab is to isolate it from the ground.

The first thing to consider when looking into different types of concrete floors is why it s so important to insulate the floor slab. Concrete is cold and hard but an insulated concrete slab can make a heated garage significantly warmer and more energy efficient. The climate the type of foundation whether the slab includes hydronic tubing for radiant heat and the severity of the local termite problem. Insulating a slab on grade depends on at least four factors.

3 clean the surface of the slab thoroughly then apply a coating of asphalt primer to help the asphalt cement bond. Martin holladay explains insulating a slab on grade in the energy smart details department. To insulate a flat roof with a concrete deck we recommend a warm deck construction method where the vapour control layer is sandwiched between the concrete deck and a layer of rigid pir insulation boards. This layer of roof tiles is fragile inherently and roof cannot be used for walking etc.

Building another sloped tiled roof over current flat concrete roof supported by metal. Paroc air keeps the roof structure dry without any mechanical systems. Follow label directions and allow it to dry thoroughly.
