They are therefore compliant for use in restricted areas such as conservation areas.The R7 range sits in a slider frame meaning it is better suited for more modern homes. It is very similar in design to the R9 system with the only difference being that, due to its slimmer frames, the vents are completely flush on both the interior and exterior.
Both ranges are A rated, come with an easy to clean rebates and can have butt hinges to complete the retro timber look.
Both ranges are available in a wide choice of colours and bespoke styles, they also have a range of furniture available, both modern and retro, including the stays that original timber windows have.
Feel free to call us to discuss the range in more detail.
