The DF 75 Si range of aluminium windows has been developed to incorporate many specialist double glazed aluminium window profiles which, when used in conjunction with many of the standard DF 75 Si aluminium opening vent and frame products, allow the construction of bespoke high performance window assemblies.

Assisted by the integrity of its advanced polyamide thermal break technology, such assemblies reduce the need for complex

and costly sealed unit specifications to obtain demanding thermal performance requirements.

These flexible aluminium window assemblies can include fixed and opening light as well as panels and doors to make up a single larger aperture solution. The inherent strength of the system allows for units to be constructed offsite. The Sapa DF 75 Si aluminium window system is suitable for both new build and refurbishment projects, commercial and residential.
