Secondary Glazing

Our exclusive range of secondary glazing is supplied fully assembled and comprises an aluminium outer frame joined to a seasoned hardwood surround which allows for a neat, unobtrusive installation even in the most difficult situations.

A range of hardwood sub-frames and scribing trims can be used to assist face fixing, reveal fixing and the coupling of units. This allows the satisfactory refurbishment of our largest primary windows. Suitable for all types of premises including grade one and two listed buildings, schools, colleges, hospitals, universities, hotels and commercial buildings i.e. offices.


Better by Design
We have a comprehensive range of styles to suit just about every application, including Horizontal Sliders, Hinged Units, Fixed and Lift-Out Units, Vertical Sliders as well as Balanced Vertical Sliders and Tilt-in Balanced Vertical Sliders. We can supply frames in white, silver or brown as standard and can accommodate any R.A.L. colour upon request to suit individual requirements.

We can also provide a wide range of glass types such as clear, patterned, toughened, laminated and acoustic.


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
The 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.
