Replacing your windows could seem like a tricky task, especially if you happen to live in conservation areas where your choices are slightly limited. Older windows – those in heritage buildings, for example – look beautiful, but their thermal efficiency is often dismal. Replacing these windows can sometimes be difficult, due to their traditional style and slim single glazing. Luckily, there’s a solution… Residence windows could be what you need. But what are they, and what’s the difference between R7 and R9 windows?

What are Residence windows?

Residence collection windows use innovative technology to provide excellent energy efficient solutions for windows that require a traditional style. They are high quality uPVC windows, able to be used in any property with 28mm double glazing and 44mm triple glazing. One of their main benefits is that they are thermally efficient, improving the energy ratings of any property they’re installed in, achieving an A+ status.

Residence 7 windows

Residence 7 windows have a flush sash on both the interior and the exterior, creating a beautiful design. The R7 windows are designed to emulate a wide range of manufacturing techniques, meaning these windows will look equally at home in a modern new build and a traditional style of property. These windows come with a range of joint options, as well as colourways and hardware.

Residence 9 windows

Residence 9 has a slightly different window style, in that only the exterior sash is flush. The interior has a decorative feature that replicates that of the 19th century timber. These windows are crafted to imitate timber windows from the 1800s, and use a variety of authentic manufacturing techniques, such as butt joints. This makes them especially beneficial for historical properties as they blend into the existing style.

What is the difference?

The difference between the R7 and R9 windows is their chamber design. R7 windows have seven chambers, whereas R9 windows have nine chambers. The number of chambers within a uPVC window improves its thermal efficiency, with the more chambers the better. This makes the R9 windows slightly better performing in terms of thermal efficiency.

There is a design difference between these two styles of window, with R7 windows having a flush sash internally and externally, whereas R9 windows are flush on the exterior but have a stylised design on the interior. Generally, R9 windows are more suited to traditional properties, whereas R7 windows are versatile in their uses with many modern property owners electing to install them.

Why should I choose Residence windows?
