How Liniar PVCu profiles work
PVCu is natural insulator, so it is one of the most energy efficient materials for a window frame, multiple chambers act as barriers, making it difficult for heat inside a property to be transferred through and escape outside.
Liniar has patented additional features that make is frames more energy efficient
Warm edge spacer bars can be selected, separating each glazed panel for higher energy efficiency
Patented thermal dam creates a multi chamber thermal barrier at the frame’s outer edge
Profiles accept double or triple glazing
Patented bubble gasket is co-extruded alongside the frame so no heat loss or leaks
Unique glazing slipper creates a thermal barrier to seal the perimeter keeping the cold out
