Q-LON: the polyurethane foam seal for timber frames
Q-LON is Schlegel’s high performance gasket, made from a special polyurethane foam core that allows high durability and superior recovery performance. The extruded variant is suitable for timber windows with 3 mm grooves and comes in different rebate and foam sizes, covering casement windows, sash windows and timber entrance doors.
Aquamac: the only weatherseal built solely for timber
Aquamac is the only weatherseal specifically designed for timber windows and doors, impervious to paint and stain for ease of maintenance. It does not shrink or stretch even in extreme climatic conditions, and its excellent memory retains the original shape for a consistently high standard of weathersealing.

As well as timber windows and doors, Q-LON composite gaskets are also proven across a wide range of sectors and applications, from airtight, fire-rated sealing for insulated wall panels and glazed partition systems, to window and door sealing in buses, trains, yachts and construction vehicles, as well as reducing conditioned air loss, dampening mechanical vibration and protecting outdoor HVAC units from water infiltration and UV degradation.
