Double glazed Windows by Reliant
Double Glazed Windows can come in a variety of shapes, sizes, and materials. One of the most popular types of windows is uPVC Windows, where uPVC stands for unplasticized polyvinyl chloride windows. These are a popular and durable choice for many modern homes. Unlike traditional materials, uPVC is a low-maintenance, long-lasting material that doesn’t warp, rot, or require regular painting. uPVC windows can complement any home’s aesthetic, from contemporary to classic. Their sturdy construction ensures excellent insulation, keeping your home warm in the winter and cool in the summer, while also reducing outside noise. When you choose uPVC Windows from Reliant Windows, you can get them in a variety of styles, colours, and finishes.
First manufactured in 1935, uPVC Windows didn’t truly become popular until the 1980’s. They have been continually improved since their conception and choosing modern uPVC windows now offers numerous benefits for any homeowner. This can include increased energy efficiency and enhanced security. These windows often feature multi-chambered frames and advanced double or triple glazing, significantly reducing heat loss and helping to lower energy bills. Additionally, uPVC’s robust nature provides improved resistance against forced entry, allowing you that added peace of mind. With their long-lasting, weather-resistant performance, uPVC windows are an excellent investment for anyone looking to enhance the comfort, safety, and overall value of their home.

Aluminium Windows
Aluminium windows are a sleek and contemporary option, perfect for homeowners looking to add a modern touch to their property. Known for their slim, stylish frames, aluminium windows maximise the glass area, allowing more natural light to flood into your home. Despite their slender appearance, aluminium is incredibly strong and durable. Therefore, they offer a long lifespan with minimal maintenance. Resistant to rust, corrosion, and the elements, these windows are ideal for both residential and commercial properties, providing a premium finish that lasts.
One of the key benefits of aluminium windows is their exceptional strength-to-weight ratio, making them suitable for larger window designs and expansive glass installations without compromising on security or insulation. This can be especially beneficial for commercial installations. Modern aluminium windows are also highly energy-efficient, with advanced thermal break technology that helps to reduce heat transfer and improve your home’s energy performance. In addition to their durability and efficiency, aluminium windows are fully customisable, with a wide range of colours, finishes, and styles available. They are prized for offering both versatility and elegance for any type of home.

Casement Windows
Casement windows are a versatile and practical choice, offering a classic design that suits a wide range of home styles. Hinged at the side and opening outward like a door, casement windows provide excellent ventilation, as they can be opened fully to capture breezes and direct fresh air into your home. Their simple, functional design makes them easy to operate. They often feature a crank or handle mechanism for smooth opening and closing. Casement windows are available in various materials, including uPVC, aluminium, and timber, ensuring they can be tailored to match both modern and traditional homes.
Casement windows are renowned for their energy efficiency. Since they form a tight seal when closed, they help to minimise drafts and heat loss. Consequently, contributing to lower energy bills and a more comfortable home. Casement windows also provide enhanced security, as the hook-shaped locks embedded into the frame are incredibly difficult to force open from the outside. With their practical benefits, sleek appearance, and wide range of design options, casement windows are a durable and stylish choice for any homeowner looking to improve their property’s aesthetics and functionality.

FAQ's
Double Glazing FAQs
Do you Need Planning Permission for New Windows?
In most cases, planning permission is not required for replacing existing windows. However, if your property is listed or in a conservation area, you may need permission to ensure the new windows meet specific guidelines.
How Long Does it Take to Install New Windows?
Typically, it takes around 1 to 2 days to install new windows, depending on the number of windows and the complexity of the installation. Larger projects may take longer.
How Do You Know When to Replace Windows?
Signs that it’s time to replace windows include drafts, difficulty opening or closing them, condensation between panes, and rising energy bills. If your windows are over 20 years old, it may also be time to consider an upgrade.
What Causes Condensation on Windows?
Condensation on windows occurs when warm, moist air inside the home comes into contact with the cooler surface of the window glass. This causes the moisture in the air to condense into water droplets. Common causes include high humidity levels from cooking, showering, or drying clothes indoors, and poor ventilation, which traps the moisture inside the home.
How to Stop Condensation on Windows?
To reduce condensation, improve ventilation by using extractor fans or opening windows, particularly in rooms with high humidity like kitchens and bathrooms. Installing double glazing or upgrading to energy-efficient windows can also help prevent condensation.
How Does Double Glazing Affect Energy Efficiency in My Home?
Double glazing significantly improves energy efficiency by reducing heat loss through the windows. This helps to keep your home warmer, reduces energy consumption, and lowers your heating bills.
