Insulation is now a key component in any build. Investing in insulation is money well spent which will give a generous payback through lower heating costs. The primarily role of insulation is to make the thermal conductivity of the insulation that of trapped, stagnant air.The effectiveness of insulation is commonly evaluated by its R-value. However, an R-value does not take into account the quality of construction or local environmental factors for each building. Construction quality issues include inadequate vapour barriers, and problems with draft-proofing. In addition, the construction properties and density of the insulation material itself is critical.

All insulation has an R value, and a U value to allow you to critically evaluate the performance of each one.

The R value:
This is a measure of thermal resistance used in the building and construction industry. The bigger the number, the better the building insulation's effectiveness.

The U value:
The U value is the opposite of the R value, meaning the lower the number the better. The U-value describes how well a building element conducts heat. It measures the rate of heat transfer through a building element over a given area, under standardized conditions.

At Glynns we can show who all your options from polyiso to rockwool. In some cases several insulations will help you achieve the desired R value and U value. Once we have the area you need to cover and the application we can advice and price all your options. We divide insulation into four area's:
