Sliding Patio Doors.

Lift and Slide/Sliding Door

The Metal Technology System 25Hi+ Sliding / Lift and Slide Door has been designed to offer the specifier a sliding opener with pleasing site lines and all the benefits of weather performance, thermal enhancement and security.

Thermal Performance
Metal Technology's range, in conjunction with the correct glass specification, is designed to aid compliance with the latest thermal requirements of the current building regulations.

The polyamide thermal break profiles have been specifically designed to minimize heat transfer across the door profiles. This innovative and advanced thermal break technology provides the basis of the 25Hi+ system.

Thermal performance is further improved through the introduction of specially designed foam profiles. These reduce radiation heat loss across the air cavities within the door profiles to provide additional thermal enhancement.

The 25Hi+ system offers significantly improved U-frame values over more traditional thermally broken aluminium door systems.

Metal Technology can provide tailored U-value calculations using their dedicated estimating software to calculate overall project average door U-values for their full range of systems.

Construction
Frame members are mitre cut at 45 degree, corners are reinforced with corner braces and mechanical cleats. All frame joints are sealed during construction against entry of water.

Glazing
The system can accommodate 28mm to 32.8mm glazing units. Glass is set against a captive gasket in the sash frame with a co-extruded wedge fitted internally. Special bridging setting / location blocks are provided to fit into the sections.
