Rzęsa UV is an artificial plant mat measuring 50 x 50 cm, made for building green walls. The sprigs are about 3-4 cm long and form a dense, small-leaved surface imitating humped duckweed — the plant that covers the surface of lakes and ponds. The backing is an open, flexible mesh about 4 mm thick.
How many mats to order
One mat covers 0.25 m², so the quantity comes from a simple calculation: take the measured area in m², multiply by 4 and round up to a whole piece. The manufacturer asks you to add an allowance on top of that for offcuts, because fitting the mats to the edges means cutting part of the material away.
Measure the area before ordering and buy the whole quantity at once — the mats are laid side by side, and a difference between production batches would show on a single wall.
Where it can be fitted
The mat is UV-resistant, which is what makes it suitable outdoors — on a terrace, a balcony, a veranda or a building facade. It also resists moisture and breaking, so it takes rain and the occasional knock.
It mounts on a wall, a ceiling or a column, whatever the size and shape of the surface. The open mesh is pliable, so it can be pulled around curved surfaces — corners and round pillars.
Cutting, fitting and finishing the edge
The mesh cuts with ordinary household scissors: it can be trimmed at an angle or have a hole cut in it for an electrical socket. A staple gun is useful for fixing the mats to a wooden substrate.
At a free edge the 4 mm backing mesh is visible, so the manufacturer recommends either recessing the mat into a reveal or fitting a finishing trim. Where the mat meets a wall, ceiling, floor or skirting board directly, no extra trim is needed.
