Trend Aquamac 21 (Brown - 10m) available for next day delivery from Brighton Tools
Strip is fitted into the door frame rebate (head and jambs) as three cut pieces forming a compression or wiping seal.
The seal is butt joined at the corners.
To seal the door bottom, a weather bar is mounted into the threshold section.
It is important that the seal does not abut the weather bar but runs to the threshold section in front (weatherside) of it, to maximise water permeability resistance.
