Quality assured trims

Liniar’s range of consumables includes its own matching uPVC foam trims and architraves. Designed and manufactured in-house using superior materials, tooling and machinery to ensure consistent quality, they provide a perfect match to Liniar windows, doors and roofs. Trims include D mould trims, cloak trims, beads, quadrant trims, adjustable angles and architraves in different sizes and colours.


Foam Trims

Liniar's uPVC foam trims are designed and manufactured at the same UK extrusion facility as its range of windows, doors and roofs – using the same high quality manufacturing processes and materials.

Not only are Liniar foam trims made from the same 100% lead-free uPVC, the foiled woodgrain finishes are factory fitted in-house and therefore match our other products perfectly.
