Question 1

Are aluminum windows better than vinyl?

Accepted Answer

Aluminum offers higher strength (6m spans), longer lifespan (40-50 years vs 20-30), and is 100% recyclable. Our thermal break models achieve U=0.59, matching vinyl insulation while retaining structural integrity.

Question 2

Which is better, vinyl or aluminum windows?

Accepted Answer

Vinyl for short-term budget, aluminum for durability, typhoon zones, and large dimensions. We have focused on aluminum for 14 years because commercial & luxury projects always choose aluminum.

Question 3

Does aluminum foil keep heat out of windows?

Yes but it's ugly and annoys neighbors. Low-E glass reflects infrared heat while remaining transparent. All FAXINI windows include Low-E coating as standard.

Question 4

Why do people put aluminum foil on windows?

Cheap temporary fix. But it blocks vision, looks poor, and may violate HOA rules. The smart upgrade is Low-E glass windows.
