Welcome to Granada Secondary Glazing

The specialist Secondary Double Glazing Company

We specialize in the supply & installation of Internal Secondary Double Glazing for Noise and Thermal Insulation.

We supply and or install our products into flats, houses and commercial premises throughout the UK and Ireland wherever there is a need for Noise and/or Thermal Insulation, especially where the character of the property makes more modern replacement type windows inappropriate or, in the case of Listed or Conservation Area properties, where they are not allowed.

When the major consideration is to Reduce Noise, Secondary Double Glazing will always be much more effective than replacing the existing windows.

An additional benefit of Secondary Double Glazing is that it provides increased security.

We currently produce over 35,000 secondary glazed units per year with a capacity within our current facilities & resources to produce more than 50,000.

Our largest single job to date has been the supply & installation of over 700 secondary windows during 2007 to Lloyds TSB for their Faryners House offices, London, on behalf of Main Contractors ISG Interiors.

We also regularly manufacture & supply single secondary glazed windows to all parts of the UK & Ireland.

Quite literally, no job is too small for us, and no job is too large.

It is a matter of pride to us that we make a point of providing the same level Service, Quality and Value for Money to all of our Customers, whether they are interested in the supply of one secondary glazing unit to be delivered to Lands End or John O'Groats, or for the supply & installation of 700 secondary windows anywhere in the Country.

The System

Our range of Secondary Glazing comprises a slim aluminium outer frame joined to a seasoned hardwood surround, usually all finished in white, which allows for a neat, unobtrusive installation, even in the most difficult situations.

A range of sub-frames and scribing trims are used to assist face fixing, reveal fixing and the coupling of units. This allows for a sympathetic installation to all types of properties and all types of windows. Suitable for all types of premises including Grade One and Two Listed Buildings and Conservation Areas.

The Range

We provide a comprehensive range of styles to suit just about every application, including Horizontal Sliders, Hinged Units, Fixed and Lift-Out Units, Vertical Sliders, 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.

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.
