Owners who can fix side channels to the shopfront usually get the closest fit from aluminum panels, made for that opening with seals clamped against the frame and floor.
Tenants often cannot fix anything to the facade. ABS panels and Oxford barriers need no installation and can be kept in the stockroom; ABS suits a long frontage and Oxford suits a single door. Both hold back and divert water, and some seepage can occur.
Whichever barrier goes across the front, check the rear and service doors as well. Sandbags are a compact way to cover them.
