Insulation Efficiency

Our range of secondary glazing is renowned for its thermal efficiency. Varying degrees of improved thermal insulation can be achieved by using such glasses as Pilkington K and Low E. If glass is thermally at risk then care must be taken to specify toughened glass. The harmful effects of ultra violet radiation can also be reduced whilst letting in solar heat. In addition specialist films can be adhered to the glass to further increase thermal insulation whilst adding to the security of the product and the premises.

Noise Reduction

Our units have been tested for sound reduction at the AIRO Acoustics Laboratory (an accredited NAMAS Testing lab, number 0483) in accordance with BS2750: part 3 and BS5821: part 3 1980 : 1984, using a purpose built sound transmission suite.
