INSULATION INTERIORS
Understanding how the roof contributes to your thermal performance can help you to make your home more energy efficient
ensuring the room below is warmer during the winter and easier to regulate during the summer. This makes it easier to control the energy levels required to heat the house, without increasing carbon emissions.
MEASURING THE EFFECTIVENESS OF INSULATION MATERIALS There are three different values that are used to express the quality of the insulation material. The R-value measures a material’s
thermal resistance – the higher the -value, the lower the heat loss. Insulation material with a high R-value needs to be less thick than a product with a lower R-value to achieve the same insulation quality. Or, the higher the R-value, the less you need of the material.
The Lambda value measures a
product’s thermal conductivity. It is the opposite of the R-value – the lower the lambda value, the lower the heat loss.
or your insulation to be as efficient as possible, you want to use materials with a low lambda value, but a high -value. A U-value is the sum of the thermal
resistances of the combined layers that make up your roof. The lower the U-value, the better insulated your roof is and the more energy you save.
DIFFERENT ROOFING SOLUTIONS In a climate like the ’s, roofs need to withstand lots of rain. A pitched roof which diverts precipitation from the roof thanks to the slope, is a standard solution for residential buildings and there is a variety of materials to choose from. Three commonly available roof materials are concrete tiles, terracotta tiles and fibre-cement slates. Concrete tiles are relatively heavy and notorious for absorbing moisture and water. This can cause frost damage in winter or lead to the build-up of mould, unless they have a protective coating. Terracotta is a natural material and its porous

nature of this makes it susceptible to frost damage without an additional protective layer or glaing. ibre cement roofing slates are increasingly popular. Made of a mix of naturally available ingredients cement, fibres, sand, water and air, they are robust for all weather conditions, with an excellent fire performance classification, lightweight and easy to work with, and compatible with all of these types of insulation. When a roof pitch is made higher to accommodate a warm roof system – and hence has longer rafters – fibre cement slates are a good option, as they are lighter than natural slates and other heavier materials, and last just as long.
Understanding how the roof contributes to the thermal performance of a home can help you to make your home more energy efficient in the coming years.
