Sealed Units


We can have quality double-glazed or triple-glazed sealed units manufactured to size to all the current specifications on the market. Whether you want to replace a broken down misted up unit, change the obscuring pattern, or add a leaded design, we can do it all. Just give us your measurements and requirements and we would be happy to provide a cost.

Replacements Units
Over time the seal around a unit can break down, then condensation can get trapped between the panes giving a misted up unit. If your windows/doors are pre 2002 they would likely be standard float glass or toughened float glass, with an aluminium spacer. Aluminium spacer bar comes in 8 different widths so with 4mm glass both sides you end up with the following overall thickness; 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, and 28mm. Different thickness can be made using thicker glass, but this is rare. As well as silver finish the spacer also comes in dark bronze, white or gold finish so matching with existing is easy.

If you have windows or doors that were installed between 2002 and October 2010 then it is likely you would have a low-e glass on the inside pane to meet the thermal efficiency regulations of the time. The most popular one used during this period was Pilkington K glass, which is a hard-coat low-e glass. It is sometimes possible to see this by a very slight tint to the inside pane when standing at an angle, but generally looks just like clear float. Some lesser thermal effeciant windows installed between 2002 and October 2010 may also had Argon gas in between (instead of air). Argon gas is a colourless, odourless, inert and safe gas which is present in the Earth's atmosphere that when filled inside a unit helps stop heat escaping through the glass. As aluminium windows are generally not as thermally efficient as Upvc or wood.

The window/door regulations were tightened again from October 2010 onwards to improve the thermal efficiency. This meant that windows and doors needed to be tested as a whole unit with the glass and frame together, so different manufacturers are using different setups depending on the type/profile being used. The most popular setup seems to be a softcoat low-e, with argon and a warm-edge spacer. We can have units made with 2 of the best softcoats on the market - Planitherm Total + and Climaguard A. Along with warm-edge spacer avaliable in Black or White.

Slimline Units
Designed for the sash window market we can get units as thin as 12mm with a 7mm sightline made using a 4mm spacer. They do have to be gas filled to be effective. They also stricter size limitations, cost slightly more and inevitably always have a higher risk of breaking down quicker due to the limited sealant. However they are a option for frames that cannot take thicker then 12mm glazing.

Triple-Glazed Units
We can also do triple glazed units, which can be made using Annealed or Toughened Glass. Although more expensive than double glazed units they often give better U-values and acoustic reductions, plus can be made using Low-E coating on the glass. Argon or Krypton gas can also added for extra insulation too.

UPVC Windows & Doors
As well as units we can have high quality Upvc windows and doors made to the best specifications. After a lot of experience with different profiles we now use either 60mm Tritec part sculptured system, or Advance 70 chamfered system. They can be made in white, woodgrain or to many different colours. Feel free to contact us with your requirements.
