Questions

Frequently asked

How do I check uPVC profile quality?

Look for sound wall thickness, multiple chambers, steel reinforcement, lead-free UV-stable formulation, and a recognised branded system.

Why does profile quality vary so much?

Cheap profile cuts corners on wall thickness, chambers, material, and reinforcement — hidden until the window warps, fades, or sags.

What should I ask the maker?

About the profile brand, wall thickness, reinforcement, and whether it's lead-free and UV-stable. Ready answers are a good sign.
