A window or door’s U-value is the measurement of thermal transmittance; it is used to discover how much heat is transmitted through the sealed glass unit. If a sealed glass unit is performing well, then it has a low U-Value as less heat is allowed to escape....

Can you cut a hole in my sealed glass unit for a cat flap?

Yes, we can. All our sealed glass units can be cut to fit the dimensions of your cat flap. Contact us and we can discuss any additions to your doors.

Why has my double glazed unit failed after sealing it in with builders’ grade silicone?

We don’t recommend using anything other than an ultra-low modulus silicone, so the choice of builders’ grade silicone used may not have been the best for your sealed glass units. We ensure that the products in stock help to expand the life of your sealed glass units. It is also important to ensure that all products are used in accordance with the manufacturer’s recommendations.

Halifax Glass Double Glazing

A sealed glass unit, or double glazing as you might be more familiar with, is a common feature of most UK homes. A sealed glass unit is created by sealing at least two pieces of glass together with a spacer bar and perimeter sealant. As we manufacture our sealed glass units in house, we can make them to your exact specifications.

Argon Gas Sealed Glass Units

Enquire Now

As an alternative to the traditional sealed glass unit, many customers opt for argon gas filled sealed units instead as argon gas doesn’t distribute heat in the same way that air does. As argon is inert, it doesn’t allow heat to pass through, it makes for a better option for your doubled glazed windows.

Sealed Glass Units FAQs

Not necessarily. Triple glazing might sound better than double glazing, however it may not make your home feel any warmer.

If the insulation of your home isn’t any better than your doubled glazed windows, then a triple glazed unit isn’t going to make much of an impact.

Double glazed units can also provide a better U-value than triple glazed units, too. This is because the cavity in between glass plays an important role in creating the best U-value possible. If you’re looking to replace an existing doubled glazed unit, then the cavities between a triple glazed unit will be a lot smaller than the cavity between a doubled glazed unit – making double glazing the better option.

If you’re unsure about your sealed unit needs, don’t hesitate to get in touch and we can help you decide on the best option.

Low E glass is standard clear glass with a microscopic, transparent coating on its surface that is better at reflecting heat than the glass itself. This creates a composition that has a lower emissivity than standard glass.

Glass with a Low E coating therefore keeps your home warmer in the winter by reflecting a higher proportion of the heat back into your home. And in the summer, it can keep your cooler by reflecting solar thermal energy from outside.

Seeing condensation on your double-glazed units can be worrying – the last thing anyone wants is to think that their new windows have failed.

However, condensation on the outside means that your units have good insulating properties and are doing their job properly. Condensation on the outside of your windows happens when the air outside is cold, so the outer pane may condensate whilst keeping the heat inside your home. This will only happen for short periods, usually first thing on a morning.
