A.H Windows are leading specialists of aluminium clad tilt and turn timber windows in Kings Lynn
High quality equals high performance from A.H Windows
'Choices' aluminium clad tilt and turn windows are manufactured using high-end, quality materials such as engineered redwood, oak and meranti. Finished off using an aluminium or timber composite frame alongside a timber sash clad with aluminium. All are made to order which means we’re able to take on more unusual designs and shapes.
In addition, to ensure that the windows are protected against the weather at the highest level, a weather strip is compressed onto the frame itself by the sash, giving it the perfect protection against wind and rain.
An added bonus of our aluminium clad tilt and turn windows is that as well as being able to tilt by rotating the handle, you are also able to turn the window inwards to create a larger opening which aids cleaning of the outside glass and frame.
