Perfect uPVC Profile

Enhance your home with the most technically advanced uPVC window profile system money can buy from Liniar.


Revolutionary size-optimised chambers break up mini convection currents keeping warm air locked in.

Superior Gaskets

High performance (patented) double-action ‘bubble’ gaskets maintain consistently tight weather-seals.

Positive Drainage

Specially designed profile contours maximise natural drainage and prevent moisture build-up.

Integrated Reinforcing

Internal structures provide exceptional stiffness and rigidity whilst minimising the need for steel.

Flipper Gasket

Unique ‘glazing flipper ‘provides an additional seal to reduce cold transfer, water ingress and noise pollution.

Thermal Dam

Designed to Passivhaus recommendations, the thermal dam extrusion helps reduce heat transfer even further.
