Why it is on the shortlist
The East Midlands-made counterpart to our imported aluminium range.
Good for homeowners comparing British manufacture with imports and projects needing a locally supported aluminium route.
A brand can cover several systems with different frame depths, opening limits and thermal results. We start with the building and opening, then choose the named product rather than quoting a generic “premium aluminium” tier.
- System named on the written quote
- Glass and opening arrangement shown clearly
- Colour, hardware and threshold agreed before order
- Survey, fitting and making good itemised

“As low as” values are manufacturer reference claims. The quote must confirm the whole-product value for the ordered size and glass.

Questions
Sheerline FAQs
Common questions before you compare Sheerline on a written quote.
01Can you price Sheerline from drawings?
Yes. Send elevations or rough opening sizes. Final manufacture follows a site survey and approved drawings.
02Are the published thermal figures guaranteed for my opening?
No. They are manufacturer reference values “as low as” the figure shown. Size, glass, opening lights and frame-to-glass ratio change the finished result.
03Can windows and doors match?
Often, but the systems may use different sections. We confirm the available colour, sheen and junction details rather than assuming a perfect match from a colour name.
04What does the fitted price include?
The approved scope covers supply of the named Sheerline system, standard survey, installation, making good and certification where applicable. Structural work, unusual access and final decoration are quoted separately once surveyed.
