If you're after a sleek look to your home, aluminium frames offer slimline frames. Thanks to the strength of the aluminium alloy used, narrower frames can be made meaning more of the window is made up of glass. uPVC frames, on the other hand, are thicker and chunkier.
Windows made with uPVC are generally better thermal insulators than aluminium. uPVC is a lightweight material, which makes uPVC double or triple glazed windows quick and easy to install. uPVC can last up to 20 years in great condition, meaning your investment will be one that lasts.
Aluminium is supremely strong and durable and is highly resistant to corrosion, capable of standing up to the outside elements. While PVC windows may require periodic replacement, you can rest assured that aluminium systems will keep on working, providing style and performance without compromise.
Poor insulator: Aluminum doesn't hold in heat as well as other materials. However, weather-stripping and thermal treatment can make this less of an issue. Condensation: Moisture or even frost can form inside aluminum-frame windows, leading to problems.
Aluminum windows have an average lifespan of about 20 to 25 years. The problem with aluminum is that it's prone to damage. If you're in an area that's prone to intense weather like hurricanes or hailstorms, your aluminum windows may have to be replaced more often than the average.
It is resistant to UV rays. It does not rust, corrode or flake and is also suitable for coastal areas (unlike aluminium, which may corrode or discolour). Multiple-lock systems and shootbolt locks can be successfully installed in uPVC windows to provide enhanced security.
For one, aluminum is a corrosion-resistant alloy, meaning it's the more durable material when used in window structures. This is because uPVC windows won't really be able to stand the test of time due to their tendency to be damaged under heat exposure.
In terms of price, installing aluminium windows is always more expensive than UPVC (on a like for like basis) because of higher material and manufacturing costs. But, in the long term, aluminium can prove very cost-effective because it's a more robust material than UPVC.
uPVC Should Last Between 20-35 Years.
Despite their robustness, uPVC windows and doors are prone to sagging and sashing due to their lightweight and also because they are structurally not as strong as aluminium windows. Too much heat can even result in the rupture of their frames.
Is uPVC toxic? uPVC in its finished form, as in when your windows are manufactured, is not a toxic substance. When uPVC burns it does become toxic, releasing dioxides into the environment which are harmful. However, unless you are planning to burn your window frames, uPVC is perfectly safe throughout its lifespan.
Casement windows are considered better than double-hung windows at keeping out drafts since the window seal is generally quite tight. Casement windows are good when you want to "scoop" cooling outside air into the house.
Durability. Aluminium windows have can last up to 30 years. This is because, aluminium is considerably more resistant to the outside elements compared to other frames, making them less likely to warp or rot as a result. Aluminium also has a high strength-to-weight ratio, making them harder to dent.
Nevertheless, uPVC windows and doors are completely resistant to strong tropical rains. The latest technology used by Encraft complying Waterproof Standards BS EN 1027 & BS EN 12208 through its Class 9A (Casement series) & class 4A (Slider series) acts as a shield of protection (waterproof) during monsoons.
Are Aluminum Windows Worth Replacing? Absolutely, especially if you have aluminum windows that are over 20 years old. Today you have access to tons of window options that will look great and reduce your energy waste.
Yes. If your windows are more than 20 years old it is probably time to start thinking about replacing the lot. Many professionals agree that if homeowners can afford it, they are better served by replacing all their windows in one order. The installation team can complete the full job in a couple of days.
Because of its high solid protection properties, UPVC soundproof windows and doors can help diminishes outside commotion by 80-95%.
The strength and security of uPVC profiles
uPVC frames built using high-quality raw materials are strong and highly stable, and are often considered burglar-proof glass doors and windows that are high on safety.
Simply put, there is no difference between the UPVC and PVCu because the two abbreviations represent the same material being Un-plasticised Poly Vinyl Chloride. Installers use UPVC in the promotion windows, doors and other home improvement products but it is also referred to as PVCu.
uPVC windows are solid, impenetrable and virtually impossible to break into.
