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.
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.
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.
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.
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.
uPVC Should Last Between 20-35 Years.
Why the construction of aluminium windows make them predisposed for condensation. Materials such as metal, in this case aluminium, have a high U-value. In building parlance, a U-value relates to the insulating properties of a building material. The higher the U-value the lower its ability to insulate.
Aluminium window frames require very little maintenance with intermittent cleaning and perhaps oiling of the window ironmongery required over time. When cleaning the windows no specialist cleaning substances, treatments or techniques are required making aluminium frames extremely easy to maintain over their lifetime.
uPVC is an extremely thermally efficient material and can provide your home with greater heat insulation than aluminium and wood windows can. For a modern home that consists of many modern fittings and features, uPVC is likely to be your best option as it will maintain the style of the property.
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.
Durability: Fiberglass replacement windows are perhaps the strongest option available, known for their resistance to extreme temperature and also for their durability. Vinyl windows can be reinforced with interlocking sashes.
You can use a dehumidifier in your conditioned space. This will help you lower the humidity levels in the room. You can insulate your aluminum frame to reduce heat transfer. This would keep your frame warmer and prevent condensation buildup.
As stated before, condensation occurs when humid air encounters a cold surface. If you want to avoid your aluminium windows getting too cold, investing in a good pair of curtains will do the trick.
Whilst aluminium boasts several positives it does come with a downfall, it's a highly conductive material. As a result, aluminium doors and windows are prone to losing heat, easily get cold and increase problems with condensation. Making aluminium a less suitable material choice for residential homes.
The external parts of uPVC window frames are continuously exposed to the elements, which eventually causes weathering. Over a long period of time window foil can start to shrink causing the foil to bubble and peel.
The Upvc on the inner and outer frames is guaranteed from discolouration, but not from fading, for a period of ten years.
Typically lasting around 20 years, which can vary between 10-35 years depending on the quality and upkeep, if your uPVC windows were installed around 1999 it's likely that they could need replacing or at least repairing by now.
Clad window lifespan
The warranty on clad window parts can range from 20 years to as long as you own the home. Aluminum is pretty bulletproof so unless the vinyl cracks in cold weather or distorts in hot, these windows can last for decades.
