Slim Sash

Minimise interruption with slimline aluminium windows. Allow them to blend into the fabric of a build or stand out creating your desired statement.

SAL300 Slim

A stylish narrow-framed window that provides the ultimate in contemporary design, maximising your view and the amount of light let into your home. Externally glazed with its slender frame depth as well, the SAL300 Slim offers a sleek appearance from any angle.

The windows are available as top-hung, side-hung casement, fixed frame, gable end glazing, clerestory windows, over-lights, and frameless glass-on-glass corners.

The SUNFLEX UK aluminium window profile consists of a modern contemporary design with square edge profiles to match our aluminium bi-fold and sliding doors. Available in double or triple glazed systems, the windows achieve impressive thermal performance.

Glass to Glass Corners

Glass corners can be configured with our slimline system, creating a slim unobtrusive clean glass edge.

Replacing a heavy looking corner post with a glass corner will increase natural daylight, whilst enhancing the feeling of space within a home. Minimalistic clean lines and slim profiles will simplify your surroundings.
