The Dualframe Glazing System signifies a new era in aluminium fenestration, with products which have been specifically designed to comply with changes to the Building Regulations which apply to thermal performance,both now and in the future. It provides an elegant, yet cost-effective and straightforward solution for low rise 'curtain walling' applications up to three storeys high.
Assemblies formed from the extensive Dualframe Portfolio may be incorporated into structural framing systems, including windows, doors and infill panels. The system is fully weatherstripped and all component profiles incorporate thermal barriers.
Typical applications might include entrance screens for commercial or public buildings, major school refurbishment projects or retail schemes where an attractive, durable and cost-effective approach is required.
The system may also be used internally to form glazed screens, draught lobbies etc. as well as glazed roofs.
