uPVC vs Aluminium vs Timber Conservatories: Materials and Maintenance
In this guide
Frame material affects sightlines, finish, maintenance and structural design, but material name alone does not establish thermal performance or durability. Compare complete systems with like-for-like glazing, reinforcement, coatings and guarantees.
| Material | Often chosen for | Check in the specification |
|---|---|---|
| uPVC | Lower-maintenance mainstream systems | Reinforcement, profile depth, colour stability |
| Aluminium | Slimmer sightlines and larger openings | Thermal break, coating and coastal exposure |
| Timber | Natural finish and repairability | Species, treatment, detailing and maintenance cycle |
Ask for colour samples in daylight and details for junctions, drainage paths and replacement parts. Maintenance claims should state the expected task and conditions rather than “maintenance-free”.
FAQs
Do slim frames automatically mean better thermal performance?
No. Sightline and heat flow are different characteristics. Compare declared performance for the complete frame-and-glass configuration.
How does ongoing maintenance differ between materials?
Timber finishes usually need planned inspection and renewal; coated aluminium and uPVC need cleaning and hardware/drainage care. Exposure and product instructions matter.
Suggested component
A weighted material comparer for sightlines, finish, upkeep and environment, with specification questions in the result.
