It is a different product from the rest of this shelf
The listing names it plainly in its last feature line: a green needle-felt lawn
(“Vliesrasen”), with a total height of 5 mm.
That is not tufted artificial grass.
Tufted artificial grass has individual fibre blades stitched through a woven
primary backing and locked in with a latex coating. The blades stand up, they move,
and from a distance they read as grass. Four products on this shelf are this, at 14 to
35 mm.
A needle-felt grass carpet is a dense mat of fibres punched together into a
textile, with a textured green surface. It is flat, uniform and extremely
hard-wearing, and it is what exhibition floors and camping ground sheets are made
of.
Both are on this shelf. They are not alternatives, and the 5 mm against 35 mm figures
make that obvious once you know what the numbers mean.
And it is the only one here with real specifications
850 g/m² total weight. Fire class Efl. 85 % polyester, 15 % polypropylene.
5 mm total height.
Four published, measurable properties.
Across the rest of this shelf: two products publish no pile height at all, six publish
no weight, six publish no fire class, and two publish no material.
This is the most useful thing on this page, and it applies to the whole shelf.
Pile height tells you how tall the fibres are.
Weight per square metre tells you how much material is there.
Those are different, and the second is what decides durability. Two mats at 35 mm can
differ by a factor of two in weight: one with dense, heavy fibre that recovers from
being walked on, and one with sparse, light fibre that lies down in a season and shows
its backing between the blades.
Artificial turf is normally specified by total weight and pile weight in grams
per square metre, precisely because height alone says nothing about substance.
One product on this shelf publishes a weight. That is a gap across the whole
family, and it means the taller mats here cannot be judged on the figure that would
actually distinguish them.
At 850 g/m² this is a substantial textile — which is what a 5 mm needle-felt should
be, since all of its material is in a very thin layer.
The fire class, which matters where these get laid
Efl under the European reaction-to-fire classification for floor coverings — the
“fl” suffix denotes flooring.
The value here is not the letter. It is that a class is published at all.
One competitor on this shelf claims to be “fire-resistant” with no classification, and
five say nothing.
And the context is a balcony or terrace: which is to say, next to a barbecue, a
fire pit, a chiminea, a candle, or somebody’s cigarette. Every plastic surface on this
shelf melts — a dropped ember makes a hard black crater in polyethylene,
polypropylene and polyester alike, and no listing here suggests otherwise.
What a classification tells you is how the material behaves in a fire test. It does
not make it fireproof.
Polyester, which is the third fibre on this shelf
85 % polyester, 15 % polypropylene.
Polyester does not appear anywhere else in this family, and it is the standard fibre
for needle-felt outdoor carpet: dimensionally stable, UV-tolerant when stabilised,
and it takes colour well.
Against the other two:
Polyethylene — soft and flexible, used for the visible blades of tufted grass
where bare feet go. One 14 mm mat here.
Polypropylene — stiff and springy, cheap, used for tall pile and for the curled
support fibre. One 33 mm mat is 100 % PP.
Polyester — used flat, in felt. Not a blade fibre.
The dimpled back
“The dimpled back supports ventilation from below and improves water drainage. The
5 mm total height offers a flat, practical solution for many outdoor surfaces.”
Two claims and both follow from the geometry.
A flat carpet laid directly on tiles has nothing underneath it. Water gets under
by capillary action and stays there, and the surface beneath never dries.
Dimples lift the carpet a millimetre or two off the floor, so there is an air gap.
Water runs out sideways and air moves through, which is what “ventilation from below”
means and it is the right thing to engineer.
Six of the seven listings on this shelf name a drainage arrangement. One does not.
What still grows on it
Moss and algae, like every product on this shelf.
A drained, ventilated surface dries faster and still collects dust and leaf litter,
and in shade that grows green film. On a felt surface it is arguably more visible
than on a tufted one, because there is no pile to hide it in.
This site’s moss killer shelf carries the products for it — the three concentrates for
stone, wood, roofs and terraces, which must never go on a real lawn. A grass
carpet is a hard surface with a textile top.
6 square metres, in one 2 m width
2.00 × 3.00 m at about 8.07 € per square metre — the second cheapest on a shelf
running from about 7.00 € to 15.78 €.
A 2 m width is better than most here: two products are 1 m wide, which means a
seam every metre.
Seams are what give any of these away — two cut edges never match exactly, and the
join catches light differently from each side. At 2 m, a typical 3 × 4 m terrace is
two lengths and one seam.
The widest product on this shelf is 400 cm, which takes most balconies with no
seam at all.
And what it will not do
Look like grass.
At 5 mm it is a green textile floor. From a first-floor window it reads as a neat
lawn; from a chair on it, it reads as carpet.
If the point of the purchase is that visitors think it is grass, the 25 to 35 mm
tufted products on this shelf are the ones that attempt it — at the cost of flattening
under furniture, because none of them is laid with the sand infill that holds tall
fibres upright.
If the point is a hard-wearing, flat, green, drained, fire-classified floor with a
published weight, this is the only product here that is specified at all.
