What is the best material to use for patio doors, uPVC or aluminium?

uPVC and aluminium patio doors have quite a few things in common, most notably; they never need to be repainted and are both highly resistant to corrosion and rot. Largely a matter of personal taste, the following differences will help you determine the most suitable patio door material for your project.

  • Sliding panels

All of our patio doors are uniquely designed, which is why our sliding doors can be installed with a number of glass panes to fit your room’s size. Our uPVC sliding patio doors can be fitted as a 2, 3 or 4 pane door, ideal for space saving arrangements tailored to terraced and semi-detached houses, flats, and balconies. Whereas our aluminium patio doors can be designed with up to 6 panes, perfect for creating striking focal points and contemporary ‘walls of glass.’

  • Thermal efficiency

When it comes to efficiency, thanks to their multi-chambered design, uPVC sliding doors offer the best performance. Although, if your patio door replacement project requires the slimmest frames combined with dependable draught-proofing qualities, our aluminium sliding doors from Origin aren’t far behind, featuring multi-layered, insulating frames complete with innovative thermal break barriers designed to prevent heat from escaping.

  • Maximum door size

When it comes to unique designs and expansive configurations, aluminium is much more flexible than uPVC. Manufactured around 30% bigger than uPVC patio doors, aluminium can accommodate complex shapes and designs with ease. So, if you’re looking for a simple and compact patio door replacement, uPVC is probably your best option, with larger, wider projects more suited to slender aluminium patio doors.

  • Stability & rigidity

Unlike traditional timber and standard uPVC, aluminium actively resists swelling, cracking, splitting and warping no matter what the weather throws at it! Providing excellent stability come what may, its unceasing strength is the key to its long-lasting durability; able to last at least 30 years, maintenance free. That said, our uPVC patio doors feature steel reinforcement and a 6-point locking system as standard.
