An orangery is a very different kind of room extension.
Its clever design uses solid brick or uPVC pillars to carry the roof load, with glazed sections set between the pillars. And in thermal terms, the solid construction holds heat more effectively and keeps a steadier temperature through summer and winter.
The Advanced Group installs bespoke double glazing for orangeries across Glasgow and throughout Central Scotland.
Every installation is backed by our 15-year guarantee, with 0% finance available and no deposit required.

What an Orangery Is
Orangeries date back to 17th century Europe, where large country houses built dedicated rooms to overwinter citrus trees through the colder months.
The design relied on tall windows, solid brick walls, and a partially glazed roof to draw in natural light while holding enough heat to keep plants alive indoors through winter.
Contemporary orangeries follow the same principle, with uPVC or timber pillar construction, solid insulated roof panels, and a glass roof lantern set into the centre to bring light in from above.
Earlier orangeries used oak or hardwood frames throughout.
Modern construction in Scotland uses uPVC profiles instead, delivering the same proportions without the painting, retreating, and swelling that timber demands in a wet climate.
For Glasgow homeowners who want to add extra space and create a dedicated living space without moving or committing to a full house extension, an orangery sits fantastically between the two options.
A well-built orangery bridges home and garden properly, usable in every season because the insulation and construction hold up where a conservatory does not.
Your Orangery from The Advanced Group
uPVC Frame and Pillar Construction
Our orangeries use high-specification uPVC profiles throughout: the pillars, the cornice, the roof kerb, and the window frames set between the solid sections.
uPVC holds its colour without painting or staining, won’t swell or warp in Scotland’s wet climate, and handles decades of use without deteriorating.
The material also contributes to the thermal performance of the room, particularly at the pillar sections and door frames where cold transfer from outside needs to be controlled.
Windows and Doors
The windows and doors within an orangery frame use the same uPVC profiles and double glazed sealed units as our standard window and door range.
Triple glazing is available as an upgrade where thermal efficiency is the priority, and low-emissivity glass coatings with argon gas filling come as standard across all sealed units.
If you are replacing windows elsewhere in the house at the same time, we can match the frame colour and profile across both installations so the property looks consistent from outside.
Glass Roof Lantern
The glass roof lantern defines an orangery visually and sets it apart from a standard extension.
Set into the solid roof structure, the lantern fills the centre of the room with natural light from above and gives the space a sense of height that a solid roof cannot achieve.
We can specify self-cleaning glass on roof lanterns, so the glass stays clear without requiring access ladders or specialist cleaning.
Lantern framing is available in white, anthracite grey, or black to match the rest of the orangery specification.
Thermal Insulation
The solid sections of the orangery roof and walls are insulated to current Building (Scotland) Regulations standard.
Combined with thermally efficient glazed units and the uPVC frame construction, a properly built orangery holds heat far more effectively than a conservatory with a glass or polycarbonate roof.
A well-specified orangery connects to the existing central heating system and does not require supplementary heating to stay comfortable through the colder months.
Our happy clients have used their double glazed and triple glazed orangeries as dining rooms, sitting rooms, and home offices year round because the insulation standard matches a conventional extension rather than a glass structure.
The Orangery Installation Process
The process starts with a free consultation and survey at your property. We take the measurements of your old openings to prepare a full and accurate specification and quote. No obligation at this stage.
From the survey, we prepare full drawings and a fixed price. You review the specification in writing and agree the design before any work is commissioned.
Your orangery’s glazing is manufactured to the exact survey dimensions. The frame, sealed units, and roof elements are made specifically for your opening and arrive on site ready to install.
When the glass is ready, we arrange a date that suits you for installation.
Our team shows up on time and prepared, and carefully works around any items you may have in the space.
Once your modern glazing is installed, we will guide you through the care and maintenance requirements for the glazing and frames, and hand over your 15-year guarantee documentation.
