Whatever your property, you’ll find a style to suit. We can even work with older, listed and period properties.

Your home’s security is always top of our minds. That’s why all our double-glazing windows have unique 14-point locking systems, approved by the Secured by Design initiative.

All our products come with a 10-year guarantee from the Plastics Window Federation for complete peace of mind.

Double glazing vs single glazing

Double glazed windows are far better than their single glazed counterpart in every aspect. A double glazed unit has two panes of glass instead of one, which leaves a pocket of argon gas between them both. The secondary glazing improves heat retention and noise reduction. Single glazed windows easily allow heat to escape as there’s no argon gas to stop it, which causes your house to be colder. A single glazed window is also more prone to cracking or shattering as there’s not an extra pane of glass to strengthen the window.

Single glazed windows are also more prone to condensation, which can eventually lead to more serious issues for your house and health. In a modern world, there is no place for single glazing as it’s outdated in every way. You might argue that they’re cheaper than double glazed windows, but regular windows won’t save you money on your energy bills or add value to your home. If you have the choice, you should always opt for double glazing!

Is It Worth Replacing Old Double Glazing?

Yes, absolutely! If you’re worried about replacement windows cost, rest assured that replacing old double glazed units is well worth it. Old windows can become ineffective over time, and modern technology is helping to make double glazed windows better than ever. Your existing windows might be more dated than you realise.

There are many benefits to replacing old double glazed windows and doors. Window materials like low e glass help make your new windows more thermally efficient. The increased energy efficiency will reduce heat loss, lowering your heating bills and saving you money in the long run. As well as improving heat retention, having your windows replaced can also reduce external noise, giving you a quieter home. Toughened glass offers great security benefits too.

What’s more, you can increase your property value by replacing windows. New double glazed windows are desirable to potential buyers and so is a good energy rating. Upgrading your double glazing is a great investment!
