The Ultimate Guide to Double Glazed UPVC Windows 




When it comes to improving your home’s energy efficiency, aesthetic appeal, and security, UPVC windows are an excellent choice. In recent years, they have gained immense popularity in the UK due to their many advantages over traditional wooden and metal windows. Whether you’re renovating your home or building from scratch, this guide will help you make an informed decision.

 

What are Double Glazed UPVC Windows?

 

UPVC stands for Unplasticised Polyvinyl Chloride, a type of plastic that is rigid and stable. UPVC windows are manufactured using this material, which is renowned for its durability, low maintenance, and insulation properties. Compared to traditional window materials, such as timber and aluminium, UPVC windows offer a wide range of benefits that make them an ideal choice for many homeowners.

 

Styles of Double Glazed UPVC Windows

 

UPVC windows come in a variety of styles to fit different architectural designs and personal preferences. Here are some of the most popular styles in the UK:

 

  1. Casement Windows

 

Casement windows are hinged on the side and open outward, allowing for excellent ventilation. They come in various sizes and can be fitted with multiple panes. This style is perfect for contemporary homes and is known for its energy efficiency.

 

  1. Sash Windows

 

Traditional sash windows slide vertically and are often found in period properties. UPVC sash windows replicate the look of wooden sash windows while offering improved energy efficiency and less maintenance.

 

  1. Tilt and Turn Windows

 

Tilt and turn windows have a unique mechanism that allows them to open inward from the top or the side. This provides flexibility in ventilation and makes them easier to clean from the inside.

 

  1. Bay and Bow Windows

 

Bay and bow windows extend out from the home, creating more space and allowing natural light to flood the interior. They are often used in living rooms and can add significant character to your home.

 

  1. Fixed Windows

 

Fixed windows are stationary and cannot open. They are ideal for areas where ventilation is not a concern but where you want to enhance the view and natural light. They can be combined with other window styles for aesthetic appeal.

 

  1. Fully Reversible Windows

 

These UPVC windows can tilt inwards and rotate to allow cleaning from the inside, making them a practical choice for higher floors. They are often installed in apartment buildings for ease of access.

While selecting UPVC windows, always compare quotes from multiple suppliers and consider customer reviews to ensure quality service. Keep in mind that the cheapest option may not always provide the best value in terms of durability and efficiency. Investing in good quality UPVC windows can significantly enhance your home’s comfort and efficiency, making it a worthwhile consideration.













Colour Options 

 

One of the significant aesthetic advantages of UPVC windows is the wide range of colours available. Unlike wooden windows, which often require periodic painting and treatment, UPVC windows maintain their colour without fading. Popular colour options include:

 

  1. White

 

Classic and timeless, white UPVC windows are widely used and fit well with most homes.

 

  1. Off-White/Cream

 

For a warmer tone, cream or off-white UPVC windows can provide a softer look.

 

  1. Grey

 

Grey UPVC windows have become increasingly popular in recent years, offering a modern and sophisticated touch.

 

  1. Black

 

Black UPVC windows provide a striking contrast and are often used in contemporary designs.

 

  1. Wood Effect

 

For those who love the look of wood but want the maintenance-free quality of UPVC, wood effect finishes are an excellent alternative.





Benefits of UPVC Windows

 

UPVC windows come with several advantages that make them an appealing option for homeowners:

 

  1. Energy Efficiency

 

With excellent insulation properties, UPVC windows help to keep your home warm in winter and cool in summer. This can lead to reduced energy bills.

 

  1. Low Maintenance

 

Unlike wooden windows, UPVC requires minimal maintenance. A simple wipe down with soapy water is often sufficient to keep them clean.

 

  1. Durability

 

UPVC is resistant to rot, rust, and corrosion, which makes it a long-lasting option. A well-installed UPVC window can last 20 years or more.

 

  1. Security

 

Most UPVC windows are fitted with multi-point locking systems that enhance security, making it harder for intruders to gain entry.

 

  1. Noise Reduction

 

Double or triple glazing options increase sound insulation, helping to create a quieter indoor environment.

 

  1. Cost-Effective

 

Given their low maintenance and energy efficiency, UPVC windows are often more cost-effective in the long term compared to alternatives.




Downsides of Double Glazed UPVC Windows

 

While UPVC windows have numerous benefits, there are also some drawbacks to consider:

 

  1. Aesthetic Limitations

 

While there is a variety of colours and styles available, some homeowners feel that UPVC lacks the character of traditional wooden windows.

 

  1. Expansion and Contraction

 

UPVC can expand and contract with temperature fluctuations, which may lead to issues with the frame’s fit over time, although this is largely mitigated by quality installation.

 

  1. Environmental Concerns

 

UPVC is a plastic material, and while it is recyclable, the production process has environmental impacts that some homeowners may wish to consider.

 

  1. Initial Cost

 

While long-term costs may be lower, the initial investment for UPVC windows, especially premium options, can be higher compared to basic wooden options.

 

 



Installation Tips

 

If you’re considering installing UPVC windows yourself, here are some essential tips to keep in mind:

 

  1. Measurements are Crucial

 

Accurate measurements are vital to ensure that the windows fit correctly. Measure the height and width of the window opening at several points to get a precise measurement.

 

  1. Check for Structural Integrity

 

Before installation, ensure that the surrounding structure is solid. If the wall is rotting or crumbling, it may need repair before you install new windows.

 

  1. Use Quality Sealants

 

Using high-quality sealants will help prevent air and water leaks, ensuring that your windows perform efficiently.

 

  1. Consider Professional Help

 

If you’re not confident in your DIY skills, consider hiring a professional installer. Proper installation is crucial for performance and longevity.

 

  1. Follow Manufacturer Guidelines

 

Always adhere to the manufacturer’s installation instructions to ensure that the warranty remains valid.
