Steel windows in Cornwall
We design and install steel windows throughout Cornwall, from Truro and Falmouth to Newquay and St Ives, with fixed written quotes after a free survey.

Fitting steel windows in Cornwall
Cornwall's coastal properties and granite cottages need robust external detailing, while internal screens help small cottage rooms share light.
You get one fixed written price after survey, with the material, glass and finish named on the quote. Lead times are confirmed in writing when you sign off the drawings, so you can plan the rest of your project around them.
We cover Truro, Falmouth, Newquay and St Ives, plus the villages and towns between them. Lead time is 4–6 weeks from signed-off drawings, and we confirm dates in writing when you sign off the drawings.
What we can include
- Hot-dip galvanised, then polyester powder coated
- Thermally improved steel sections with double glazing
- Trickle vents where ventilation rules require them
- Secure multipoint or espagnolette locking options
Steel windows are window frames made from hot-rolled steel sections, galvanised against corrosion and powder coated, then double glazed. Read the full guide to steel windows.

Steel windows in Cornwall: questions
Can steel windows be used in a new extension?
Yes. Steel windows and glazed walls are a popular choice for rear extensions, and they can be detailed to match steel doors in the same opening.
Are steel windows energy efficient?
Modern thermally improved steel windows with double glazing can meet the energy rules for replacement windows in England, which currently set a U-value of 1.4 W/m²K or better. We confirm the figure for your specification.
