At High Spec Windows and conservatories Ltd, we fabricate UPVC windows using leading edge technology in the glazing industry.

High Spec offers seamless welding corners allowing you to obtain windows and doors of uniform quality and superior aesthetics.

It is no longer necessary to choose between aesthetic quality and technical performance: with the advent of GRAF Synergy seamless welders, we offer the best of both.

The revolutionary welding process eliminates the grooving process, resulting in seamless corner joints even on vinyl profiles.
