Patio Doors

Let the best of the outside in with an elegant and space-saving in-line Sliding Patio Door. This is the ideal garden door solution for homeowners who wish to take advantage of even more natural light and almost panoramic views, without compromising on valuable living space. Available with the option of multiple sliding sashes, in-line Patio Doors are a functional and stylish home improvement to match your windows. Available in a range of colours and woodgrain finishes these doors provide the perfect bridge to your conservatory or outdoors.

Whether fully opened or closed, these doors maintain their crisp lines and commanding levels of visibility in either extreme. A one-piece stainless steel track enables effortless opening and closing, allowing luxurious access between home and garden, truly letting your house breathe. When closed, maximum weather resistance is ensured thanks to double brush seals on all four sides, coupled with an unique quadruple seal interlock.

They are equally adept at insulating your home against heat loss, helping to reduce your energy bills and carbon footprint and keeping your property safe and secure. Security plays a central role with these innovative doors. They feature toughened or laminated glazing, with multi-point hook locks. The entire door frame is fully steel reinforced for strength and durability. These doors are fitted with ‘anti-lift’ blocks and are available with anti-pick cylinder locks to deter even the most-determined potential intruder. All our Sliding Patio Doors come with the long-life, low-maintenance and insurance backed guarantees you’d expect from Capital UPVC.
