Why uPVC Double Glazed Windows Are Ideal for Cornish Homes
Living in Cornwall means you’re no stranger to the unpredictable weather, from chilly, windy days by the coast to the occasional warm summer afternoon. That’s why choosing the right uPVC double glazed windows for your home can make a huge difference in terms of comfort, energy savings, and maintenance.
Excellent Insulation
One of the biggest advantages of uPVC double glazed windows is their ability to keep your home well-insulated. In Cornwall, where the weather can often be damp and chilly, these windows help to trap and keep heat inside, making your home feel warmer during the colder months. Thanks to their insulation properties, you’ll stay cosy inside, but you may also save money on your heating bills. In fact, energy-efficient double glazing windows can help reduce your household’s energy usage by up to 20%.
Noise Reduction
Whether you live near a busy street, the coast, or a popular tourist area, noise can be a common issue in Cornwall. Luckily, uPVC double glazing acts as an effective sound barrier. The space between the two panes of glass reduces external noise, making it easier to enjoy a peaceful and quiet environment inside your home, even when the wind is howling or people are walking by.
Durability and Low Maintenance
Cornwall’s coastal climate can be tough on building materials, especially when it comes to wood and metal frames that can corrode in salty sea air. However, uPVC windows are incredibly durable and resistant to the elements, which makes them an ideal choice for homes near the coast. They won’t rust, warp, or require constant maintenance like wooden frames. Simply cleaning them occasionally with soapy water is all that’s needed to keep them looking brand new.
Long-lasting Investment
Another great feature of uPVC double glazed windows is their impressive longevity. With the proper care and maintenance, these windows can last for decades, making them a great long-term investment. Whether you live in a period property or a modern new build, you’ll appreciate the durability and low-maintenance nature of uPVC, keeping your home insulated and sound proof for longer.

By choosing uPVC double glazed windows, you’re not only enhancing the energy efficiency of your home, but you’re also enjoying superior soundproofing, greater protection from the weather, and a hassle-free option that’s perfect for Cornwall’s coastal conditions.
Understanding the Styles and Finishes Available
When choosing uPVC double glazed windows, it’s important that you pick a style and finish that complements your home’s design while also offering the benefits that you need for your home. There are various styles and finishes available, so you can personalise your windows to suit your taste, whether you live in a period property or a contemporary build.
Window Styles
Read below to learn more about some of the window styles available for your home.
Casement Windows
These are the most common style of double glazing windows and are hinged at the side. They open outwards, giving your maximum ventilation. This style is especially suited to traditional and modern homes in Cornwall, offering both functional and aesthetic appeal.
Tilt and Turn Windows
A versatile style perfect for homes that need easy cleaning and safe ventilation. These windows can either tilt inward at the top or swing open like a door, making them ideal for homes with limited space or in hard-to-reach areas.
Sliding Sash Windows
If you own a period property or one that needs to maintain its traditional charm, sliding sash windows are a great choice. These windows slide up and down and are often associated with Georgian or Victorian properties. Many window manufacturers now offer uPVC versions of this style, making them low-maintenance while still keeping a classic look.
Finishes and Colours
You can also find a range of finishes and colours when it comes to uPVC windows, giving you the freedom to choose a style that reflects your personal taste and matches the style of your home.
Woodgrain Finishes
These finishes mimic the appearance of wood, providing a natural look without the upkeep of timber. Available in finishes like oak or rosewood, these are perfect for homeowners who want the traditional look but the convenience of uPVC.
Modern Colour Options
If you’re looking for a more contemporary style, colours like anthracite grey, black, and white are popular choices for new builds and modern renovations. For a sleek and uniform look, you can opt for a dual-colour frame, with one colour on the outside to complement the exterior of your home and a different colour inside to suit your interior.
Energy Efficiency Ratings: What You Need to Know
Energy efficiency is quite a serious key consideration to make when selecting your uPVC double glazed windows. Not only will energy-efficient windows help keep your home warmer, but they can also reduce your carbon footprint and lower energy bills.
Window Energy Ratings
Look for uPVC double glazing windows with a high Window Energy Rating (WER). This rating, from A++ (the most energy-efficient) to E (the least efficient), indicates how well a window will keep heat inside your property. For homes in Cornwall, where winters can be cold and damp, an A or A+ rated window will most likely provide the best insulation.
Triple Glazing vs Double Glazing
While triple glazing offers better insulation, uPVC double glazed windows are better for Cornwall’s milder climate. Double glazing is often a more cost-effective solution, providing excellent insulation without the higher cost of triple glazing. The extra layer of glass and the gas-filled gap between the panes of a double-glazed window work together to create a strong thermal barrier.
