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.
