Warm roof cold roof difference.

What is the difference between a warm pitched roof and a cold pitched roof. A cold pitched roof is where the insulation is placed either between or between.

So what kind of difference does this make. In this video i explain three different ways of building a flat roof using the war. In this technique insulation is laid between the rafters. The temperature of the roof structure is almost the same as the outside.

A cold roof isn t as cold as the title suggests. Namely the insulation layers. A warm roof is much easier to install offers great thermal performance and can also add height to the flat roof. The object being to design out the possibility of warm moisture laden air coming into contact with a cold surface and condensing.

A warm roof is the easiest and most cost effective type of insulation and is an ideal choice for pitched roofs. A warm deck roof can be very simple to install and offers higher thermal performance at the cost of a higher. An example of a cold roof set up warm roof vs cold roof.

The breakdown warm roof vs cold roof there are pros and cons to both a warm roof and a cold roof. What is a cold roof. A cold roof in a flat roofing scenario is the one whose thermal insulator is below or inside the structure of the roof.
