Which is the Best Type of Double Glazed Sash Windows?

Double glazing is an excellent way to keep the inside of a room cooler in summer and warmer in winter. Unlike ordinary windows, it offers greater protection from the elements. But there are some types of double glazed sash windows that are better than others. For example, casement windows open inwards and form an awning. These windows are ideally suited for homes that need maximum ventilation and unobstructed views. They are also available with motor chain drivers, which allow you to open them remotely.

Double-glazed windows

There are many types of double glazed sash windows. Double glazing windows can be large or small, and made of many different materials. These windows can be rated according to their energy efficiency. The most energy efficient windows are A-rated, but there are also a variety of lower-rated windows available. A window with a C-rating is still considered energy-efficient, and it meets the UK building regulations.

The space between double-glazed windows acts as an insulator. The gas is filled between the two panes of glass and serves as an additional layer of insulation. The most common gas used is argon, which has low conductivity properties. The spacer between the two panes of glass is also filled with a desiccant to reduce the amount of moisture in the air space.

Aluminium double glazed sash windows

Double glazing windows are a great way to save money on energy bills, keep your home warmer in winter, and reduce noise from outside. However, the best type depends on your requirements and your budget. While most homeowners opt for uPVC double glazing, as they are easy to clean and maintain, aluminium double glazing may be a better option if you are looking to increase the amount of daylight inside your home or are environmentally conscious.

Aluminium is also eco-friendly and recyclable. The material is not prone to decay and rot in wet or snowy climates. Another benefit of aluminium double glazing is that it doesn’t cost a lot to install. Plus, it’s easy to cut to any size and is free from warping and expansion.

Tilt and turn uPVC windows

Tilt and turn windows open and close with the turn of a handle. They provide healthy air circulation and ventilation. Their wide opening allows maximum air exchange. Additionally, they are easy to clean and offer easy access to both sides of the sash. Moreover, they meet fire regulations and the requirements of egress windows.

Tilt and turn windows can be made in a wide range of designs and colours. Some uPVC windows come with wood grain finishes. Both have excellent energy efficiency.

Secondary glazing

There are a number of different types of secondary glazing. Some are fixed to the existing window while others are removable. The primary difference between them is the level of insulation they provide. Secondary glazing made from Perspex is the most effective in insulating your home. In addition, it is more affordable than traditional uPVC double glazing.

Another important feature of secondary glazing is that it helps reduce air leakage in your home. Since it increases the surface temperature of your windows, it reduces the chance of condensation. This prevents damp and mould formation.

Benefits of Sash Windows

If you are thinking about replacing your old windows, you might want to consider sash windows. This style of window has many benefits, including low maintenance and character. There are several different types of sash windows, including uPVC sliding sash windows and Accoya wood sash windows.

uPVC sliding sash windows

Besides being durable and affordable, uPVC sliding sash windows are ideal for improving the overall look of your home. The uPVC material is incredibly resistant to the elements and doesn’t warp, peel, or rust. It is a highly preferred material for window frames and is even approved for heritage and conservation properties. It also has an excellent level of security and is draught-proof.

uPVC sliding sash windows feature excellent insulating properties. This is due to their innovative multi-chambered structure, which means that they deliver excellent thermal insulation, enhanced security, and excellent soundproofing. The versatility of these windows allows them to be used for a variety of applications, from residential to commercial.

Accoya wood sash windows

Accoya wood sash windows are environmentally friendly and long-lasting. They also resist rot and insect damage. And, they don’t require much maintenance. Accoya wood is an excellent alternative to tropical hardwood. Moreover, they have a 50-year warranty above ground.

Accoya wood has exceptional dimensional stability, and it is resistant to water and humidity. This means that the window won’t become drafty during the winter season. Additionally, it won’t shrink or swell like other woods do. This is one reason why Accoya is the preferred material for restoration of old sash windows. Accoya is also carbon-negative, meaning that its entire life cycle has a low environmental impact.

Low maintenance

uPVC sash windows are gaining popularity and have a number of low maintenance benefits. These windows do not require repainting or replacement and can withstand the elements for a long time. In addition, they are very easy to clean. All you need to do is clean them using soap and water. The sashes open, so you can easily clean the crevices inside the window.

Aluminium sash windows are also very low maintenance, requiring just one coat of varnish. The occasional wipe-down with a damp cloth is all that is required. These windows also look timeless and are made from high-quality materials. With proper care, they can last for up to 20 years. This makes them an excellent investment for any property and will increase the estimation of the property.


One way to increase the security of sash windows is to install a security lock. These locks are a good deterrent to burglars and are easy to install. However, they are not as effective as security restrictors. In addition, they do not provide the 100mm opening option that security restrictors do.

Another way to increase security is to install a metal clip on the sash window’s tracks. These clips bend into the channels of the window sash and are locked open by a key. These can be costly, but can prevent a child from climbing out of a window. You can also use a hinged wedge lock, which permits partial opening of the sash and prevents it from lifting fully.
