Double Glazed Sash Windows

Traditional timber sash windows can be one of the most attractive features of a home – but they are not always energy-efficient due to their tendency of allowing heat to escape from a property. One of the ways of getting around this problem is by having your existing sash windows reinforced with double glazing. There’s no need to simply replace your sash windows when you can simply update them instead, and by having them restored with features such as double glazing and soundproofing you can make them extremely durable and robust without needing to compromise on their character.

Typically, safety standards will no doubt have been heightened since your windows were first installed, so we can assure you that these standards are met when we offer double glazed sash windows. This can mean using features such as safety glass for instance. Meanwhile, argon gas is sometimes used to further enhance the thermal properties of the windows that we renovate. If you’re looking for brand new double glazed sash windows, we can help with that too, whilst ensuring that they don’t look out of place within your environment.

Many people opt for uPVC when choosing windows, but we believe that the thermal properties offered by alternative, more traditional materials in tandem with the double-glazing itself make them a superior choice. Our windows are hand-crafted and offer timeless, alluring qualities. We can offer our service to anyone living in the London area and we have been accredited by such firms as Fensa, GGFI and The Guild of Master Craftsmanship. By using our simple and quick online app you can get a quote for our services without even needing to get in touch – though we are always available if you do have any queries.

A lot of the time, homeowners think that their windows cannot be restored when they can. Unless sash windows are in a particularly bad condition, there is nearly always a way to breathe new life into them. Our high standards of craftsmanship and care mean that we can reinforce your sash windows to meet today’s standards of durability without affecting their character in any way. Often these windows are one of the finest elements of a property, offering classic appeal that never goes off-trend. In a world of uPVC windows – often labelled as cold and sterile, it’s no wonder that traditional wooden sashes have remained so popular for so long.

Restoration is preferable to replacement, not just in terms of preserving character, but in terms of saving money too. Our skilled technicians know every trick in the book when it comes to making classic windows function properly, and once their work is done you should find extra value added to your property too. With only the highest-quality hardwoods on offer, once we’ve added double-glazing to your windows, they shouldn't need to be restored again until decades down the line. Choose us for sash windows in London that look beautiful and function perfectly. Don’t look for inferior alternatives – choose double glazed sash windows.
