Sealed Units

Sealed Units

A Sealed Unit is also known as Double Glazed Unit or Insulated Glass Unit. It is made up of two panes of glass separated by a spacer cavity. At least two sides of the spacer are filled with desiccant to absorb moisture within the cavity and prevent moisture condensing on the inside of the unit. A hot melt or silicone sealant is then applied to seal the unit.To increase a unit’s thermal efficiency, the cavity can be filled with argon gas.

There are many different types and combinations of double and triple glazed units we do. Annealed, toughened, laminate, thermal, self-cleaning, acoustic, solar and fire rated. They are made with silver aluminium spacer as standard (black and white also available) and can also be in a number of thicknesses.

Slimline

Slimline units are used when double glazing is required, however the window frames are too thin for the
standard sealed unit. Slimline units have an overall thickness of 12mm and we use Edgetech’s Heritage Super
Spacer which is 3mm thick which allows ultra slim sightlines in our slimline units.

Slimline Heritage

These slimline units are made using specialist glass for period buildings. This type of glass offers a truly authentic traditional looking window as it gives the slight distortion effect of old crown glass.

Stained Glass

Also known as Future units, this is truly a modern window with a traditional twist. These beautiful windows are made with traditional craftsmanship combined cotemporary double glazing. Future units allow the thermal efficiency and security of present-day windows coupled with the visual impact of a traditional leaded light.

Warm Edge

Warm edge spacer improves the thermal efficiency of the traditional sealed unit. Warm edge spacer conducts less heat,nprevents heat loss and reduces the risk or condensation.
