Double Glazed Windows That Look the Part

If you’re looking for new windows, choice is important. We offer a fantastic range of different window styles, from flush casement windows to tilt and turn windows. Whatever your property, you’ll find a style to suit with us. We can even work with older, listed and period properties. If you prefer the look of wooden windows, choose from our range of double glazed timber windows rather than modern uPVC. Our flush sash windows in particular, offer a traditional appearance with all the benefits of modern technology.

Your home’s security is always top of our minds. That’s why all our windows have unique 14-point locking systems, approved by the Secured by Design initiative. Not only that, but they’re energy-efficient, so you’ll save money on those bills! We’re members of the Guild of Master Craftsmen, and FENSA-approved. Our products also come with a 10-year guarantee from the Plastics Window Federation, providing you with complete peace of mind.

Double Glazing vs Single Glazing

Double glazed windows are far better than their single glazed counterparts in every aspect. Having two panes of glass instead of one leaves a pocket of argon gas in-between. Along with improving heat retention, the second layer also aids in noise reduction. Single paned windows easily allow heat to escape as there’s no argon gas to stop it, which causes your house to be colder. Without an extra pane of glass to strengthen the window, there’s more chance of it cracking or shattering.

Single glazed windows are also more prone to condensation, which can eventually lead to 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 In a modern world, there is no place for single glazing as it’s outdated in every way.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, 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 the cost of replacement windows, rest assured that going this route 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 actually be more dated than you realise.

There are many benefits to replacing old 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 the windows. New double glazed windows are desirable to potential buyers, as is a good energy rating. Upgrading is a great investment!
