We utilise leading manufacturers to design high-performance double glazing.

Impressive Double Glazing Performance

Thermaframe provides the perfect functionality with its double glazing, ensuring homes in Sevenoaks benefit from secure, but simple to operate accessibility. There’s even a low threshold option available, where our customers can tailor the width of their doors to allow wheelchairs through them.

Our uPVC doors operate exceptionally at any location around the house, with their seamless aesthetics, and our variety of door designs. On the other hand, uPVC windows complement the exterior of your house while complementing the interior with a classic, timeless appearance.

These doors are constructed from high-grade uPVC from Halo and Eurocell, depending on the range you choose, incorporating intelligent components and a highly innovative manufacturing process to provide optimum performance.

Alternatively, aluminium windows and doors are the perfect contemporary solution for your double glazing. We offer the high standard profiling systems of Halo, and of Smart, to ensure fantastic quality and simple functionality. Also, we install stunning wooden windows that add timeless appeal to your home.

Our high-performance aluminium bi-fold doors are multi-configurable, meaning you can open them in a myriad of ways, such as fully stacked left-to-right or right-to-left, or closed in the middle and opened either side. You can choose which leaf is the main opening point as well.

We also install market-leading orangeries that add a touch of glamour to your home and extend your possibilities for social gatherings.

Our house extensions are another great way to create more space in your home, improving your quality of life and increasing your property’s value.

Thermally-Efficient Double Glazing

Where uPVC is innately thermally-efficient, aluminium struggles to perform to a similar extent. Although it provides a relatively low conductivity of heat, it needs something to counteract the cold bridging.

Our innovative aluminium double glazing has this covered for your peace of mind. Our profiling systems feature the very latest innovative technologies to achieve fantastic energy ratings.

For instance, aluminium doors using the Smart Visofold 1000 profile feature a thermally-broken frame and polyamide bridged profile to retain heat within your home.

uPVC double glazing by Halo allows thermal inserts to sit in the reinforcement chamber, providing additional insulation and outstanding thermal efficiency for your home.

If you want aluminium windows and doors but require the utmost thermal-efficiency like uPVC, we have a final option of Warmcore bi-fold doors.

Highly-Secure Double Glazing

Our uPVC windows are highly-secure and can be upgraded to conform to PAS24. All double glazing comes fitted with high-security multipoint locking mechanisms.

Our composite doors make a thoroughly secure front door for your home, so if you want something that is highly resistant to weather and attack, Thermaframe’s composite collection is for you.

These possess a thick timber core as well as an impressive premium lock, ensuring your home stays protected from the front, or for further security, install composite at the back.

Our uPVC windows and doors are highly-durable, promising never the warp, rot, or decay over time, unlike their counterparts in timber. This ensures they provide incredible quality and performance throughout.

Our uPVC double glazing is fabricated using highly-innovative components such as PCE gaskets, weather seal flipper, and glazing pad from Halo, and low-level gaskets from Eurocell for fantastic weather performance.
