The barrier seals against the flat outside surface of the doorframe and down onto the step (stone, concrete or wood) as shown in figure W1.

Figure W2: Wooden frame clip arrangement
Fig W3 and W4 shows an example of part of the doorframe outside being hidden (narrow). This is a result of the outside wall being rendered in sand and cement coating/pebble dashed. By adding a wood batten to the doorframe (as shown fig. W3 and W4) it will allow the barrier to clip to the doorframe. (wood batten can be painted to match the doorframe).

Floodshield on UPVC doorframes
UPVC Doorframe Figure U1
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 U1 and fig U2.
UPVC Doorframe Figure U2
There are 2 types of rainwater drainage points on upvc doorframes,
- CONCEALED DRAINAGE POINT- Where the bottom frame member meets the step/sill. If this is the case then it needs to be sealed with a sealant (as per instructions supplied). Modern upvc frames are such a good fit that the rainwater entering the property i.e. collecting on the thresholds is virtually non existent.
- DRAINAGE HOLES (with hoods that unclip in the bottom frame member) – If this is the case, then providing the holes are more than 1cm (10mm) above the step then the barrier will be ok. If however the drainage holes are less than 1 cm above the step you can temporarily seal these with duct tape when flooding is imminent.

The barrier needs to overlap (approx) 1 ½ inches (38mm) each side of the doorframe to allow the barrier to clip onto the doorframe (FIG U3 and U4).
Choose the barrier size that avoids the plastic trim at the edge of the doorframe.
