Aluminium has become an increasingly popular window material in the UK, and trade installers are taking notice. Slimline frames, strong thermal performance and a modern appearance make aluminium a good choice for clients looking for something different from standard uPVC windows.
The challenge is finding a supplier that can back that demand with reliable lead times, competitive trade pricing and the specification you need for each project.
At Boston Trade Frames, we supply high-quality, supply-only aluminium windows to trade professionals across Lincolnshire and beyond. Windows are manufactured to your requirements, giving you consistent, ready-to-fit products backed by an experienced trade team.
Why trade installers are turning to aluminium
Aluminium frames combine exceptional strength with slimline profiles, making them well suited to projects where clean lines, natural light and unobstructed views are important.
One of the key benefits of aluminium windows is their ability to accommodate larger panes of glass without requiring bulky frame sections. This can maximise natural light while maintaining the strength and durability expected from modern aluminium systems.
For installers, aluminium also offers plenty of design flexibility. The range of window styles, colours, glazing options and configurations makes it possible to specify products for contemporary new builds, modern homes and period renovations.
Durable and low maintenance
Aluminium is naturally durable and requires little ongoing maintenance once installed. This makes it a practical choice for customers looking for long-term performance without the regular upkeep associated with some traditional materials.
Powder coating provides a durable, weather-resistant finish, helping aluminium frames maintain their appearance over time while requiring minimal maintenance.
Specification to suit the project
Every project has different requirements, so having flexibility within your aluminium window specification is important.
Boston Trade Frames’ aluminium systems incorporate thermal break technology to reduce heat transfer through the window frame and support strong thermal efficiency. Double glazing and triple glazing options are available depending on the energy ratings and thermal performance required for the project.
The range includes aluminium casement windows, tilt and turn, flush sash and French windows, giving installers options to suit different properties and applications.
Security is another important consideration when specifying new aluminium windows. Multi-point locking systems, high-security hardware and appropriate security features can provide peace of mind while helping installations meet relevant security standards.
A wide range of colours and finishes
Colour and finish can make a significant difference to the final appearance of an aluminium window. Boston Trade Frames offers an extensive range of colours and finishes, including popular options such as agate grey, chocolate brown, jet black and cream.
Frames are powder coated for a durable finish, while the availability of RAL colours provides further flexibility when a particular project calls for something more specific.
With different hardware finishes also available, you can create a window specification that works across contemporary and traditional properties.
Custom dimensions and window styles
No two installations are identical, which is why supply-only windows need to be manufactured around the requirements of the project.
From a single replacement window to larger runs of glazing for extensions or new developments, Boston Trade Frames can manufacture aluminium windows to your required dimensions and specification.
Available styles include casement, tilt and turn, flush sash and French windows, providing design flexibility across different projects. Flush casement windows can also offer a clean, minimalistic appearance where a more contemporary finish is required.
Aluminium isn’t limited to modern homes either. With the right colour, configuration and frame style, aluminium windows can also work well within period renovations where installers want to combine contemporary performance with a more sympathetic appearance.
What do aluminium window prices look like for trade installers?
The cost of aluminium windows varies depending on factors such as size, glazing specification, style, colour and finish. Boston Trade Frames quotes each project according to its individual requirements rather than relying on a standard price.
Competitive trade pricing helps installers understand the cost of their windows before committing to a project, making it easier to plan installation costs and manage margins.
For a quotation, simply provide the required dimensions and specification to the trade team, who can price the order around your project.
Lead times and delivery you can plan around
Reliable lead times are important when you’re working to an installation schedule. Delays can affect other trades, create additional costs and make it harder to keep a project moving.
Supply-only orders from Boston Trade Frames are typically ready within 2–4 weeks of order confirmation, providing a clear timeframe for installers to work around.
From a single replacement project through to a larger development, the trade team can discuss your requirements and delivery arrangements with you.
