A Range Of Looks

A uPVC French door is versatile in how the final door will look. There are 15 different colours to choose from. All colours have a woodgrain effect, except white which is smooth. A popular selection is to have white or light cream as an inside colour. This helps to brighten up the inside of a home and match existing interiors. Choosing the colour for outside often depends on matching up with the colours on the outside of a building and the existing windows. The addition of panels on the bottom half, and or bespoke astragal bars can add a nice finishing touch.

Full Opening

The exterior French door is the perfect way to open your house and allow unrestricted access between the inside and outside of your house. Many of our customers now prefer double doors to sliding patios because they allow a greater opening.

UPVC French Doors Features

The top sash opens out and the bottom sash opens in. This gives full fire escape access, but also ensures that the window has a compression seal, making it airtight resulting in a high energy rating. This is unique for sliding sash windows that are notorious for allowing air leakage. Any home can benefit significantly from implementing these windows, both aesthetically and with energy conservation. In today’s climate and with today’s standards there are few better options out there for the home buyer.

The Townhouse Sash Window comes in several configurations, finishes and features . The Townhouse Sash window can come with an arch, with sidelights, in bay and bow style or a double Townhouse Sash window design. We make the window in many different finishes, in a natural rich cream or white colour or from our woodgrain finishes like golden oak, rosewood and dark green.
