What are uPVC windows made of?

uPVC (short for unplasticised polyvinyl chloride, also known as PVC-U) is a strong, lightweight plastic that’s widely used in modern windows.

It’s durable, low-maintenance, and cost-effective, making it a popular choice for homeowners. uPVC doesn’t rot, warp or require painting, and it offers excellent insulation to keep your home warm and energy-efficient.

Security and safety

Ensure your new windows come with multi-point locking systems to give you added peace of mind. If you have young children, consider restrictors to prevent wide openings while still allowing airflow.

What energy-efficient features should I look out for?

Energy efficiency features can be confusing and difficult to get your head around, so we’ve broken down the main factors to look for when choosing your uPVC windows:

Window Energy Ratings

Like household appliances, windows also come with an energy performance rating - similar to the rainbow-style graph you see on fridges and washing machines. Established by the British Fenestration Ratings Council, the graph goes from A++ to E with A++ representing the highest energy rating.

U-values, L-values and G-values

You might have already come across these measures, but if not, they are used to understand the energy efficiency of your windows. You don’t need to get too technical, however, simply look at the coloured bands, just like you would with your household appliances. The three main measures are:

U-Value
This measures how much heat is lost through your window. When shopping for windows, a lower U-value is best because it means less heat is escaping, keeping your home warmer.

G-Value
This measures the amount of the sun’s warmth that can pass through the glass, also known as the solar gain factor. A higher G-value means more heat from the sun can enter your home, helping to naturally warm your space.

double

or

triple

glazing

We often hear from our customers about their preference for triple glazing. Whilst it does offer extra protection, the best-performing double glazing can be just as effective for your home.

Both options are great choices, and while triple glazing tends to outperform double glazing, double glazing is often more than sufficient and cost-efficient. Depending on your needs, you may also opt for acoustic glazing which can reduce outdoor noise significantly.

Ultimately, it all depends on your specific needs and preferences. Our experts can provide further advice on this, so you can make the most informed decision to suit your requirements.
