PVC window profile is the dominant framing material in the UK fenestration market. Its combination of thermal insulation, inherent flame retardancy, dimensional stability, and zero maintenance has made it the preferred choice for residential and commercial window systems for over four decades.
Our window profile compounds are manufactured by specialist European compounders with decades of experience in the fenestration sector. Every formulation is engineered for consistent twin-screw extrusion performance — with optimised impact modifiers for low-temperature toughness, calcium-zinc stabiliser systems for long-term weatherability, and precise pigmentation for colour consistency across production runs.
Whether you're extruding casement frames, tilt & turn systems, flush sash profiles, or commercial framing sections, we source compounds that meet BS EN 12608 Class S requirements for the UK climate — backed by full batch-level QC documentation and REACH compliance.
