Windows
We fit uPVC and aluminium windows suited to Truro's Georgian and Victorian terraces near the Cathedral, as well as newer estates nearby. Casement, sash, flush sash, and tilt-and-turn styles offer strong thermal performance, with conservation area homes often needing sash-style windows that preserve character while improving efficiency.

They suit flat-roofed extensions and orangeries, flooding open-plan living spaces with natural daylight. Our Scorrier-based installers fit every roof lantern to a high standard, ensuring you get the full benefit of its thermal efficiency.
Uni Blinds
Uni Blinds' integral blinds are sealed within the double-glazed unit, staying dust-free with no loose cords, ideal for busy households.

Doors
Composite, uPVC, and aluminium doors are available throughout Truro, including French and patio doors suitable for gardens in Threemilestone and Malpas. Multi-point locking and toughened glass come as standard, giving homeowners improved security and efficiency — whether you're after a striking front door or wider bi-fold doors for a garden extension.
Conservatories
We design and install bespoke conservatories using proven Wendland systems, suiting both period properties and modern homes in Highertown and beyond. Traditional Victorian and Edwardian styles work well alongside heritage terraces, while lean-to and lantern-roof conservatories suit newer builds. Guardian Warmroofs are also a popular choice for homeowners wanting year-round use.

Energy Efficiency and Lower Energy Bills
A Warmer, More Comfortable Home All Year Round
Energy efficiency is one of the main reasons Truro homeowners choose to replace their windows. Double-glazed windows are rated A++ to E for energy efficiency. According to the Energy Saving Trust, upgrading an entirely single-glazed semi-detached home to A-rated double glazing can save around £85 a year on energy bills in Great Britain. Actual savings vary by property size, current glazing, and heating type. The insulating performance of windows is measured using a U-value. This figure shows how much heat escapes through the glass and frame per square metre of window area. A lower U-value generally means better thermal efficiency, warmer rooms, and reduced energy bills throughout the colder months of the year.
Double glazing helps protect properties from damp issues in high-humidity areas. Some Cornwall homes suffer from damp conditions due to the local climate, making effective double glazing even more important. The sealed air gap between the panes reduces condensation on the interior glass, lowering the likelihood of mould and mildew developing over time.The sealed air gap between the panes reduces condensation on the interior glass, lowering the likelihood of mould and mildew developing over time. A well-sealed, condensation-resistant unit also performs better thermally, helping maintain energy efficiency and keep bills lower over time.
Planning Permission and Building Regulations
Do You Need Planning Permission?
Large parts of central Truro, including the Cathedral Quarter and Lemon Quay, fall within a conservation area, and several buildings there are listed. In most cases, replacing windows on a standard house counts as permitted development and doesn’t require planning permission.
This isn’t guaranteed in conservation areas or on listed buildings, so it’s worth checking with Cornwall Council before work begins. All replacement windows in Truro, regardless of planning permission, must still meet current building regulations for thermal performance, safety and ventilation.
Please do not hesitate to contact us if you have any questions regarding Origin Double Glazing or the products and services we provide.
A typical home in Truro can have its windows replaced within 1 to 2 days, depending on how many are being fitted. Installation typically takes 1-2 hours per window. Larger projects, including full houses or door replacements, may take a little longer. We’ll agree a timeframe with you before work starts.
Modern double-glazed doors are built with multi-point locking systems and toughened glass, so they improve both security and thermal efficiency compared with older doors. This applies to our uPVC and composite doors alike.
uPVC windows are a cost-effective, low-maintenance option with strong thermal efficiency. In contrast, aluminium windows offer slimmer frames and a more contemporary look, often suited to larger glazed areas or extensions. Both are available as part of our double glazing installation service.
We only supply quality double glazing products from trusted manufacturers, and our own experienced team completes every installation, so you have a single point of contact from quote through to completion.
Yes. Double glazing installers should provide compliance certificates after work to confirm the installation meets building regulations (such as FENSA or CERTASS certification in the UK). Keep these documents safe, since you may need them later for home insurance, energy performance certificates, or when selling your property.
