Double Glazed Sealed Units

We are the specialists in manufacturing double glazed units, otherwise known as DGU’s. All of our units are compliant with BSEN 1279 Parts 1 to 6 and carry the CE Mark.

What are DGU’s?

Double glazed units are essentially made up from 2 panes of glass, with a spacer bar to separate the 2 panes, and sealed around the perimeter to make airtight.

Benefits of Double Glazed Sealed Units

Double glazed sealed units are extremely good at heat insulation. They act to not allow any of your warm air to escape through the double glazed windows. In addition they don’t allow any of the cold air into your house. So it is the perfect barrier to protecting your home’s temperature. This would help enormously on energy saving.

Installing double glazed sealed units keeps your house cool in the hot summers. The sun’s rays can get trapped in the double glazed units helping your room stay cooler, helping to decrease the amount of energy cost from keeping a fan on.

These windows are also great at keeping you safe. With extra glass, double glazed sealed units increases the protection of your home. The double units are harder to break through and are sealed tighter than most other windows. So you have peace of mind in your own home.

They are great at reducing the amount of condensation. Double glazed sealed units decrease the amount of moister that builds up on your windows. As sealed windows are airtight it makes it impossible for condensation to grow which can cause mould on the panes.

Finally you have the benefit of less noise. Busy roads and loud towns can be annoying when you’re trying to sleep or work, a quieter home enables you to focus on the things you want to do with no distractions.

Our Guarantees

All of our DGU’s are manufactured using a dual seal system. Our standard sealant, which is polyurethane, allows us to offer a guarantee of 5 years when glazing into timber frames and 10 years into UPVC.

We also offer a specialist seal, which is an epoxy resin; this allows us to offer a 10-year guarantee when glazing into timber frames (with the exception of our Sashlite sealed units) as well as UPVC (all glazing must be in accordance with GGF regulations).

We are also able to produce triple glazed sealed units, and double glazing suitable for sound control, please contact us for further information on these products.

It is essential that the correct products are used to glaze our double glazed sealed units, please refer to this document (PDF) for more information.

Why use energy efficient glass?

Due to the importance placed on the damage to the environment in recent years, as part of the Kyoto agreement, the Government has committed to reduce the amount of greenhouse gases the UK produces. One way has been through stricter Building Regulations concerning energy efficiency.

How does energy efficient glass work?

‘Low emissivity’ (Low-e) glass is designed to reflect heat from fires and radiators back into your home, greatly improving its thermal efficiency. At the same time, it allows heat from the sun through your window, contributing to its energy efficiency.

By using less heat to keep your home warm, less energy needs to be produced, therefore lowering the overall levels of greenhouse gases and the cost of keeping your home warm.

We manufacture 2 types of Low-e glass which are readily available from stock:

There is a stylish range of textured glass, which can complement the interior ambience of your home.

Textured glass, also known as obscure glass, allows maximum light while achieving privacy or obscuring unattractive views.

We stock the complete range of Pilkington textured glass designs, there are now more than 20 to choose from, including the Pilkington Oriel range, a premium selection of etched designs. Click here for designs.

All designs are available in toughened safety glass and all are suitable for double-glazing.

Would you ever believe that glass could clean itself? Well now there are glass products readily available which can!

Self-cleaning glass has been designed for external use, either in the home or commercial buildings, and particularly effective in glass roofs and hard to reach areas.

Benefits of Self-Cleaning Glass

  • Less frequent cleaning – windows stay cleaner for longer
  • Much easier cleaning – less dirt and grime adheres to the glass
  • Save money – the cost of window cleaning is reduced
  • Clear vision through your windows – even when it’s raining
  • Neutrality and transparency is the same as normal glass
  • Less frequent use of detergents – helping to protect the environment

Our range of self-cleaning glass includes:

The increased use of glass in architecture today makes it imperative to consider the comfort of a building’s occupants. Solar control glass can be an attractive feature of a building whilst at the same time minimising, or even eliminating the need for an air conditioning system, reducing running costs of the building and saving energy.

In hot climates, solar control glass can be used to minimise solar heat gain and help control glare.

In temperate regions, it can be used to balance solar control with high levels of natural light.

Solar control glass can be specified for any situation where excessive solar heat gain is likely to be an issue, eg. large façades, glass walkways, atria and conservatories.

Our range of solar control glass offers a range of performance options to suit most building applications, the range available includes:
