PVCu Frames
Hallmark Glazed Extensions now proudly presents the latest innovations in PVCu frame design.
We offer standard stormproof windows and conservation style flush windows, featuring both welded mitred joints and square-cut timber look joints.
When combined with woodgrain foil finishes available in a range of traditional colours, these windows seamlessly mimic real wood windows, even upon close inspection.
Our selection includes vertical sliding windows in numerous colour combinations and various frame shapes, including Veka System 10 Halo, Rustique, and Deceuninck.
Aluminium Frames
Our collection includes slimline aluminium frames that excel in thermal insulation. These frames are available in dozens of different RAL colours, with White, Black, and Anthracite Grey being the most popular choices, all offered at the same price and readily available.
Today, aluminium frames can match the thermal efficiency of timber or PVCu frames. We specialise in offering products from ALUK, Sheerline, and Smart Systems, making them the top choice for Bifold and horizontal sliding doors.
Hardwood Frames
If your property is a Listed Property or located in a conservation area, fitting PVC or aluminium frames may not be possible.
In such cases, Hallmark Glazed Extensions can provide solutions that meet conservation requirements using Sapele hardwood, available in all traditional styles and factory-finished in a wide range of Teknos paint colours.
Seasoned Oak
Our exclusive range of fully seasoned, engineered oak frames is renowned as the premier oak-framed window solution, suitable for home replacements and our unique conservatory, orangery, and garden room designs.
Constructed with glu-lam technology from carefully selected 20-30mm seasoned oak boards, these frames are not only 30% stronger than non-glu-lam timber but also exhibit minimal movement, ensuring exceptional stability for windows and doors.
The natural grain of oak is particularly well-suited to meet the demands of Listed and conservation requirements.

Roof Options
Hallmark Glazed Extensions provides a diverse range of roof frame solutions, encompassing traditional oak and alternative hardwood and premium aluminium and PVC-capped roofing.
While our oak and hardwood roof frames are manufactured following our distinctive construction methods and styles, we can source aluminium lantern and conservatory roofs from respected brands such as Korniche, Atlas, Ultraframe, and Sheerline, catering to your specific style requirements.
Conservatory Roofs
A conservatory roof predominantly comprises glass and can be designed in various shapes and styles to suit your preferences and property aesthetics.
Orangery Roofs
Orangeries often feature flat periphery roofs with glazed lanterns. In some cases, these roofs may have a tiled verge, commonly referred to as a mansard orangery.
The inclusion of a substantial-sized lantern is vital to ensure ample natural light filters into the room below and any existing adjoining spaces.
Garden Rooms (Warm Roofs in the PVC Industry)
Garden rooms are characterised by a roof predominantly covered with tiles. Depending on the roof's shape, incorporating glazed panels or Velux roof lights is essential to introduce light into the space behind.
In the PVC industry, these roofs are often called "Warm Roofs" and may feature imitation tiles or slates.
Please note that projects with tiled roofs require building regulations certification, which does not exempt them from the need for a building regulations application and certification.
The Benefits of Our Glazing Options to provide all-year-round comfort
Modern glass roofs featuring quality solar control glazing can effectively reflect over 80% of heat on hot days while retaining warmth on cold days.
Using high-quality solar glass in both window and roof frames ensures efficient heat reflection on hot days and better heat retention on cold days, surpassing the performance of non-solar glass.
Click to play
With the correct glass specifications and adequate ventilation, you can enjoy a glazed extension that remains comfortable year-round, free from excessive heat in the summer or cold in the winter.
