Double glazing quotes Sevenoaks


Your Sevenoaks home will benefit from a wide range of practical performance-boosting qualities thanks to the quality of our double glazing.

Outstanding Performing Double Glazing

When you work with Thermaframe for your double glazing, you are awarded with home improvement products that give you the best of both worlds. They look amazing but also offer you a wide image of practical benefits, these include enhanced security and thermal efficiency. We think about the user with our double galling, so if there is someone in your Sevenoaks home who uses a pram or wheelchair, then we’ve got a selection of products with low thresholds.

Our wide collection of doors with exceptional double glazing means wherever you are looking to install your home improvement door, we are sure to have just what you are looking for. The quality of our doors is equally impressive, thanks to the fact that we have chosen to stock doors from the Halo and Eurocell. The quality of uPVC that is used means you can rely on any of these doors to perform brilliantly for many years to come.

This also applies to our windows, the collection is so varied that no matter the architectural design of your home, we will have a set of double glazed windows for you. We have an enviable collection of aluminium windows, each boasting the best quality of double glazing. Our ranges include Halo and Smart, which are both recognised as market leaders and offer form and function in equal measure. For a more traditional aesthetic, you can choose from our wooden windows.

If you are looking for a new way to connect with your Sevenoaks garden, then you might want to think about installing our aluminium bifold doors. Not only do they possess the highest quality of double glazing, but they also come with an innovative way of opening. These doors are multi-configurable, so you are spoilt for choice when it comes to the ways you can open and close them.

We also stock an enviable collection of orangeries and house extensions, both fitted with amazing double glazing as standard.

Thermal Efficiency

Thermal Efficiency

One of the most popular reasons for our customers choosing to install our double glazing products in their Sevenoaks homes is to reduce the cost of their energy bills. Whichever frame you choose for your windows or doors will act as an extra layer of insulation, keeping all the warm air inside your home and all the cold air outside.

Our windows, thanks to the double glazing, come with impressive energy ratings as standard and come equipped with clever ways of keeping your home warm. For example, the Smart Visofold 1000 profile has been designed with a thermally-broken frame and polyamide bridged profile, resulting in making your home more thermally efficient.

When you choose our Halo double glazing, you are rewarded with the ability to place thermal inserts into the reinforcement chamber, so giving you even more insulation than our standard double glazing can. The aluminium frame alternative is found in our outstanding Warmcore collection.

Enhanced Security

Another benefit that our double glazing products can offer your Sevenoaks home is improved security. Our uPVC windows can be enhanced to include a security system that complies with PAS24. Equally secure are our composite doors, these make a great choice for a front or back door, but it’s not just unwanted intruders that Thermaframe’s composite collection keeps at bay, it is and weather as well, thanks to their incredible weatherproofing.

These composite doors have the thickest of cores as well as a top-quality lock, so you can be confident that when you install one in your home, you are benefiting from an extra layer of impressive security.

With the quality of the uPVC we use on all of our double glazing products, you can be guaranteed that they will never warp, bow, crack or fade. When you install any of our doors and windows in your Sevenoaks home, you can expect them to last a lifetime.

One of the reasons why our uPVC double glazing performs so well is because they are manufactured using cutting-edge components such as PCE gaskets, weather seal flipper, and glazing pad from Halo, and low-level gaskets from Eurocell, which makes them completely weatherproof.
