Warm Roof Vs Cold Roof Construction

It has been used by builders for years.

Warm roof vs cold roof construction.

A warm roof is much easier to install offers great thermal performance and can also add height to the flat roof. Cold roof construction requires that a suitable ventilated air space exists above the insulation layer within which the air is constantly mobile being replenished by fresh incoming air whilst the air resident within the void space is being expelled via a natural. You create a warm roof or a cold roof simply by applying the layers of the roof in a different order. It is easy to construct and far less expensive than construction of a warm roof.

A warm roof is much more straightforward to install and provides a superior thermal performance and is therefore more costly. In a cold roof the insulation is applied between the rafters but in a warm roof the insulation is applied on top of the existing roof surface. Basically the term cold roof refers to a traditional roof or vented roof while hot roof refers to a roof that is not ventilated and which has foam insulation attached directly to the roof sheathing. The breakdown warm roof vs cold roof there are pros and cons to both a warm roof and a cold roof.

It is perhaps surprising and certainly unfortunate that some building professionals and contractors are under a misapprehension as to the precise requirements in order to achieve warm roof and or cold roof construction. Cold roof construction is the traditional method of building roofs both flat and sloped. The thermal efficiency isn t as good as with warm roof insulation. What does it involve.

A warm roof construction has many benefits over a traditional cold roof essentially it is a breathable roof construction which allows moisture to escape which in turn. The breakdown warm roof vs cold roof a cold flat roof insulation requires more work taking off old boards and replacing them and the roof surface. A warm deck roof is much easier to install offers great thermal performance but adds height to the flat roof. In climates that remain cold for a sustained period unvented roofs can cause more harm than good.

There are typically two different ways to insulate a roof a warm roof and a cold roof. However it must be pointed out that a cold roof requires more work and isn t as thermally efficient as a warm one. Whether or not a hot roof is a superior setup depends heavily upon climate homeowner needs and building plans. Namely the insulation layers.

A cold roof is best when you re initially creating a flat roof and is cheaper than a warm roof but does provide an inferior thermal performance. It has s insulation layer above the rafters and immediately below its weatherproof membrane.
