Product details


The curtain walling system is made up of a series of aluminium beams of different dimensions, designed to take bending and sheer loads. Into these grid combinations are fitted Sheerframe windows which are extruded from Sheerblend impact modified PVC, complying with BS7413.


Structural grids available in white or woodgrain, into which can be fitted a range of window styles from all the Sheerframe systems, including tilt & turn windows and reversible windows.


Curtain walling is manufactured to customers requirements, though all designs and combinations must be approved by Sheerframe. Approval is based on required deflection properties, as required in BS6375 Part 1 and in combination with the existing building and specifiers requirements.

Fittings & Hardware

For appropriate fittings and hardware refer to the individual window styles being used in the grid e.g., reversibles. Additional remote opening devices can be used on casement and tilt and turn styles where opening lights may be high.

Grid Structure

Curtain Walling grids should be constructed with reference to the Sheerframe curtain walling manual and using the methods and components supplied by Sheerframe.

Structural engineers should also be consulted on larger products where they can advise on the correct interaction between building and grid.


All structural components have been independently assessed by the Centre for Window and Cladding Technology (CWCT) at the University of Bath.


A large range of fixing brackets is available to suit most building types and methods of fixing, e.g. fixing between floors, hanging from the face etc.
