Insulation is one of the key components of a sustainable building design. A well insulated home reduces energy bills by keeping warm during winter months and cool during the hot summer days. Thus, cutting down carbon emissions linked to global climate change at the same time allows you to save money on your energy bills.
In terms of energy efficiency, investing in high levels of insulation materials for your home is more cost-effective than investing in expensive heating and cooling technologies. Therefore, it is worth taking the time to choose the right insulation materials in the framework of whole building design.
At Building Materials UK they supply a huge variety of insulation materials such as loft insulation.
Loft insulation is the most commonly used materials to maximize the energy efficiency and improve the acoustics of your home. Among the various materials used in this category includes Glass Fibre Insulation Roll or rolled loft insulation and Multi Foil Insulation Rolls.
Insulation materials are made from petrochemicals and include: fiberglass and multi foil. These materials are widely used because they are inexpensive to buy and install. Plus, there is an assumption from the building industry that the performance ability of the loft insulation materials is higher compared to that of plain walling and roofing.
Loft insulation materials work by resisting heat flow measured by an R-value; the higher the R-value, the greater the insulation. This R-value varies according to material type, density and thickness, and is affected by thermal bridging, unwanted heat flow that occurs at joists, metal stud and rafter beams.
The fiberglass or rolled loft insulation for instance provides a thermal conductivity of 0.040 W/mK and a thermal resistance of between 2.5 -5.0 m2K/W.
If you want a tear resistant, rot-proof and does not weaken over time, the multi foil insulation is one of the perfect loft insulation choices.
With loft insulation, you are contributing to a greener environment at the same time reducing cost on your energy bills.
