Bradford Gold Insulation

Bradford Gold Insulation

Bradford Gold insulation is made from glass spun like fairy floss to create millions of air pockets which impede the flow of heat through the product.

This resistance is measured by the R-value of the insulation. The higher the R-value, the better the insulation’s performance. Whilst some insulation materials can pack down or settle over time, Bradford Gold insulation is guaranteed to maintain its R-value for the life of the home (or 70 years).
