UPVC Door Frames
UPV Doorframe Figure 1
The barrier seals against the flat outside surface of the doorframe as shown.
The barrier needs to overlap onto the doorframe (approx) 1 ½ inches (38mm) each side of doorframe to allow the barrier to clip onto the doorframe.
UPVC doorframes are approx 3 inches (75mm) wide, which allows the barrier to overlap more than 1 ½ inches (38mm) if you wish as shown in fig 1 and fig 1a.
