Double glazing for uPVC Sash Windows

With so many advantages, it’s no surprise that double-glazed sash windows are becoming an increasingly popular choice for period property refurbishment projects. It’s a far simpler solution to replacing sash windows, especially for properties where timber effect windows and glazing options are limited.


What is double glazing for uPVC timber effect windows?

Double glazed sash windows incorporate two panes of glass within the framework as opposed to just one. These two sheets of thick glazing are separated by a vacuumed pocket that trap a layer of air or gas. This acts as a natural insulator, potentially improving energy efficiency by more than double compared with certain single glazed alternatives.

This high-performing method means that the draughts are kept out of your home whilst the warmth is retained. You get the best of both worlds regarding thermal performance as a result.

The benefits of double glazing

As a result of this, your double glazed windows will significantly improve your homes’ energy efficiency and could even save you money on your heating bills. Another direct result of this is an improved carbon footprint, something which has become more imperative with each passing year.

Sash Window Glazing Options

Double glazing helps contribute to the overall Window Energy Rating, or WER, that a profile achieves. G is the lowest and A++ provides the highest levels of thermal performance. Charisma Rose, Ultimate Rose and Heritage Rose sash windows can be designed with double glazing that achieves energy ratings of C, B or A.

Choosing double glazed sliding sash windows is a much more modern alternative than older timber windows with single glazing or secondary glazing. With the Rose Collection, you’re able to make the switch to double glazed, energy efficient windows while maintaining your home’s period charm. You aren’t making a compromise.

Protection and peace of mind for home security

We fit our sash windows with market leading glass as standard. Internally glazed for enhanced security, our double glazing is available in a range of thickness and dimensions. In doing this, we have something to support the different bar and midrail options that vary throughout the three Rose Collection models.

For example, an Ultimate Rose comes with 35mm sightlines, almost half the 60mm thicker sightlines of our Charisma Rose alternative. As a result, different dimensions of modern double glazing will be needed to accommodate this difference.

At the Rose Collection, our uPVC sash windows provide an all-round performance far greater than single glazed traditional timber sash windows. With this, it makes more sense than ever before to make the upgrade to out authentic uPVC alternatives. Our double glazed sash windows are low maintenance, thermally efficient, secure, long-lasting, easy to install, individually designed and manufactured and cost-effective.
