Are uPVC windows and doors suitable for coastal environments?

Yes, uPVC windows and doors are corrosion-resistant making them an ideal joinery solution for coastal areas. They won’t warp or fade in the sun or rust from salt spray in the air. UPVC is an ideal alternative to aluminium which will corrode over time. 

Why should I consider uPVC windows over aluminium?

Changes to the New Zealand building code mean that builders must install thermal breaks in aluminium double glazing to increase their energy efficiency. This increases the price of aluminium joinery which used to be the cheaper option.   

UPVC windows and doors have the highest thermal rating of any type of joinery on the market. Combined with its corrosion resistant properties, superior strength, increased levels of noise absorption, and now, lower difference in cost, and investing in uPVC is the smart option when it comes to future proofing your home. They are the global standard in thermal protection.
