In the UK, external doors are put to the test all year round.
Driving rain, high winds, cold snaps, heatwaves and constant temperature changes all place pressure on your home’s first line of defence.
But just how weather-resistant should your external doors be, and how do you know if yours are up to the job?
At AC Glazing, we design and install external doors that are built specifically to cope with the UK weather, without compromising on style, security or energy efficiency.
What Does “Weather-Resistant” Really Mean?
A weather-resistant external door does far more than simply keep the rain out. It should:
-
Prevent water ingress during heavy rainfall
-
Resist warping, swelling or cracking due to temperature changes
-
Minimise heat loss and cold draughts
-
Withstand UV exposure without fading or degrading
-
Maintain long-term performance with minimal maintenance
If a door fails in any of these areas, it can lead to draughts, leaks, higher energy bills and costly repairs.
Materials Matter: Choosing the Right External Door
Aluminium Doors
Aluminium is one of the most weather-resistant materials available for external doors. It does not rot, warp or swell, even when exposed to persistent moisture or extreme temperature fluctuations. Powder-coated finishes provide excellent protection against corrosion and UV damage, making aluminium doors ideal for exposed locations.
uPVC Doors
High-quality uPVC doors offer strong resistance to rain and wind, while also providing excellent thermal performance. Modern uPVC profiles are reinforced internally, helping them maintain shape and performance over time, even in colder conditions.
Composite Doors
Composite doors combine multiple materials to deliver outstanding weather resistance. Their solid core prevents warping, while durable outer skins protect against moisture and impact. They are particularly effective at keeping out draughts and maintaining internal warmth.
