Roof thermal insulation helps to keep a property warm in winter and cool in summer and reduces energy bills by lessening the amount of work that is required for heating or air conditioning. A well-insulated roof is not only cost effective, but also good for the environment by reducing the amount of energy that is wasted up through the ceiling.
In addition to reducing a building’s energy consumption and lowering its energy bills, roof insulation can provide a number of other benefits such as preventing cold spots in winter and hot spots in summer as well as increasing comfort and extending the life of a roofing system. The most common warning sign that a home or building requires new roof insulation is when energy consumption increases significantly over time.
Maximizing Energy Efficiency: The Importance of Roof Thermal Insulation
When the thermal insulation is not sufficient, the temperature of the surface directly adjacent to the membrane will become much warmer than the air, causing moisture entrapment in the insulation and damaging the roofing system. This can lead to sagging of the roofing membrane and the development of leaks.
To overcome this, a roof insulation material with a high R-value is required. The Prodex insulation solution has a multi-layer composite that provides superior performance and a long lifespan. It is made up of a reflective reinforced foil with high thermal reflectance and low emittance and a closed-cell polyisocyanurate FOAM centre that resists moisture, compression and deterioration. It also offers the benefit of fire resistance and a vapor barrier.
