Technal has expanded its highly successful FXi suite of commercial aluminium windows with the addition of a 65mm module designed to give specifiers more choice and flexibility to meet the requirements of Part L of the new Building Regulations.

The FXi65 window incorporates a 19mm flush polyamide thermal break and innovative gasket detailing to offer enhanced thermal performance. FXi is Technal’s most technically advanced window suite to date and will help deliver finished buildings, which heat up more quickly, stay warmer longer and cost less to run.

The design of the 65mm system accommodates 17mm up to 48mm double glazed units, and allows more economical glass specifications to be used whilst still delivering the required U-value of 2.2W/m²K, even with a glass centre pane U-value as high as 1.9W/m²K. The launch of the new module means that with the right combination of frame and glazing, the requirements outlined in Part L can be met across Technal’s FXi suite, with no compromise on quality, aesthetics, design flexibility or long-term durability.

In tests to the new, more stringent BS EN standards, FXi65 met and in some cases exceeded the requirements. The system achieved the highest classification for air permeability, A*4, in tests up to 600 Pa; it was fully watertight up to 1200 Pa and was rated up to V*C5 for wind resistance which equates to a pressure of 2000 Pa.

To simplify specification and fabrication, FXi65 shares many common accessories with the FXi46 and FXi52 ranges. The system combines proven technology, quality components and precision engineering with contemporary styling to achieve superior visual appearance, excellent thermal efficiency, and ease of fabrication and installation.

As with the other systems in the FXi suite, FXi65 can be supplied in a full range of configurations to suit most situations, both new build and refurbishment. These include fixed lights, projecting top and side hung, bottom hung, and tilt/turn.

In addition to the wide choice of polyester powder coated or Anolok finishes, FXi65 is also available in Technal’s exclusive palette of striking flecked gloss Cendré colours.
