As heat rises, majority of the energy lost is usually through the roof. Flat roof insulation is a key tool that can boost the energy efficiency of a building while reducing fuel costs. Flat roof insulation also offers your home further security from the unstable outdoor environment, including overheating in warmer climates and rain and snow in cooler regions. Structures such as balconies, rooftop gardens and roof spaces used to capture solar energy are increasingly becoming more popular. This rising trend for practical roof spaces creates even more demand for flat roof insulation, assisting to enhance the area accessible on top of your building.
Do I Need Flat Roof Insulation?
A flat roof is identified as any roof that has a slope of less than 10 degrees. Flat
roofs are fundamentally horizontal so they’re easy to identify. Thus, in
insulated flat roofs, the insulating materials are placed between your ceiling
and the roof to avoid heat from leaving or entering your property.
What is flat roof insulation?
Types of flat roofs
The different types of flat roofs are cold flat roof, warm flat roof. They both have their own specific advantages and disadvantages. Which insulation method you should choose, depends on the existing construction and the available space.
Warm flat roof is when the insulation material is applied on top of the roof construction. The roof is slowly heated, along with the space beneath. As a result, the roof is less likely to be affected by big temperature changes. Warm roof is the best way to insulate your flat roof as there are no condensation issues to contend with.
Cold flat roof is when the insulation material is applied to the bottom side of the roof boarding. The roof is not heated by the space below and it is affected by weather conditions such as temperature changes caused by heat or frost. Resulting In the roof construction and the sealing layer to shrivel or expand occurring damage over time.
How long does flat roof insulation last?
Insulation materials tend to be extremely robust. You can expect flat roof insulation to last anywhere between 25 and 40 years. It’s worth noting that warm roof insulation tends to degrade faster than cold roof insulation due to it being exposed to the elements. However, this shouldn’t cause too much concern as the insulation will last at least as long as the durable waterproofing material.
