The Litchfield Group, a market-leading manufacturer of PVC windows and external doors, has launched a pioneering bi-fold door system with a 0.8W/m2K U-Value. The Sheerframe Bi-fold door achieves industry leading thermal performance and energy efficiency thanks to a unique four-seal design. This promotes unbeatable air and water tightness, for lasting durability and weather resistance. The high performance system also features Sheerframe’s five-chambered PVC profile, which improves strength while minimising heat loss.
Ideal for use in both commercial and domestic settings, the Sheerframe Bi-fold door can be specified as either top or bottom running for convenience and versatility, with the option of a low level threshold of ease of entry, ideal for accommodating both wheelchair access or business deliveries. Furthermore, the Sheerframe Bi-fold door, available in various opening configurations, is designed with an interchangeable bead system of 28mm, 36mm 44mm to facilitate either double or triple glazing.
Sheerframe Bi-fold doors maximise light, offers clean sightlines and gives a clear opening, making the garden feel part of the home. The low maintenance profile system is also available in a variety of colours to suit individual taste and property character, and an interchangeable contour and bevelled finish.
The innovative profiles are made using 100% lead-free PVC, utilising calcium stabilisers for an environmentally friendly, totally recyclable product.
The Litchfield Group is based in Derbyshire, manufactures and extrudes a range of energy efficient envelope products, providing homeowners and specifiers with Zero Carbon solutions that meet Code for Sustainable Homes requirements.
