The benefits of a warm roof over a cold roof
In this post we consider the benefits of a warm roof over a cold roof. When it comes to constructing a roof, there are two main types of designs: warm roof and cold roof. A warm roof is a design that places insulation on top of the roof deck. A cold roof is a design that places insulation in between the roof joists. While both designs have their benefits, a warm roof construction offers a number of advantages over a cold roof. In this blog, we’ll explore the benefits of a warm roof construction.
Improved energy efficiency benefits of a warm roof
One of the primary benefits of a warm roof construction is improved energy efficiency. The insulation in a warm roof construction is placed on top of the roof deck. This means that the roof space stays warm. Warm roofs eliminate the possibility of cold spots and reduces heat loss through the roof. A benefit resulting in lower heating costs and improved energy efficiency.
Reduced condensation
Another benefit of a warm roof construction is reduced condensation. In a cold roof construction, the insulation is placed in between the roof joists. The location of the insulation can create cold spots in the roof space. When warm, moist air comes into contact with these cold spots, it can lead to condensation. This can cause damage to the roof structure and lead to mold growth. With a warm roof construction, there are no cold spots, which reduces the risk of condensation.
Increased lifespan benefits of a warm roof
A warm roof construction can also increase the lifespan of the roof. The insulation on top of the roof deck protects the roof structure from temperature fluctuations. Reduced temperature fluctuations prevent expansion and contraction. This can lead to cracking and other damage to the roof structure. With a warm roof construction, the roof structure is protected from temperature fluctuations, which can help to extend its lifespan.
Improved comfort
A warm roof construction can also improve the comfort of a building. With the insulation on top of the roof deck, the roof space is kept warm, which can help to maintain a more consistent indoor temperature. This can lead to improved comfort and a more pleasant living or working environment.
Faster installation
Finally, a warm roof construction can be faster to install than a cold roof construction. With a warm roof construction, the insulation is simply placed on top of the roof deck, while with a cold roof construction, the insulation must be placed between the roof joists. This can be a more time-consuming process, which can increase the overall cost of the roof construction.
In conclusion, a warm roof construction offers a number of benefits over a cold roof construction. These benefits include improved energy efficiency, reduced condensation, increased lifespan, improved comfort, and faster installation. While there are situations where a cold roof construction may be more appropriate, a warm roof construction is generally the better option for most buildings.
