Introducing LazyLawn 20 & LazyLawn 35
Defining the Quality of Artificial Grass
We have provided a summary below as a quick guide to what you need to consider when purchasing Artificial Grass. For the more serious minded we deal with the key technical terms below the summary.
In simple terms the MOST IMPORTANT factors to consider when buying artificial grass is:
- Density – Knowing the Density rating is vital and for a good grass it should be rated higher than 14,000 tufts per m2 – Anything over 16,000 tufts per m2 is regarded as premium product and will serve you well. LazyLawn is 16,800 tufts per m2.
- Dtex – Selecting a Dtex rating that suits your application is very important, and remember a high rating is not necessarily what you want – Consider the application demands as well as the look and feel of the grass.
These are the LESS important factors
- Yarn Weight – This is a direct factor of the Dtex and should not influence you materially when selecting a grass. What’s important is selecting the right Dtex for your application (see more about Dtex below).
- Total Weight of Grass – This is not a key factor either as it does not necessarily define quality as the overall weight of the grass can easily be influenced by the thickness of the backing. Density Rating is the key.
More Technical Detail
When purchasing artificial grass, it’s important to ask about the manufacturing specification, because that’s often what differentiates one product from another. It’s also equally important to select the specification of grass that’s appropriate for your application requirements.
You need to consider the durability, texture and visual appeal of the grass, so that the installed grass will last well – and look good – year after year.
Choosing a grass only from how it looks on the roll is not a wise, because what’s important is to know the manufacturing specification – this is what determines how the grass will look and work in future.
Artificial Grass must not look like a flat green rug in the garden after just a few short months because then it really will look really “artificial”.
We’re very proud of the high density of our LazyLawn products. Our full specification sheet is available for download here.
How do we define the Quality of Artificial Grass
The quality of Artificial Grass is measured using several factors such as Dtex, pile height, gauge, stitch rate and the backing – but just what do all these things mean?
What does Dtex Mean?
Dtex is probably the least understood factor (an abbreviation of Decitex), which is a manufacturing term used to measure the weight, of a single blade of grass, in grams, assuming that it was 10,000m long.
The Dtex rating is very important as it affects the durability and suitability for each application. For example, if you’re installing grass in a heavy-duty, high traffic area, you should consider using a higher Dtex, but that comes with a downside.
The higher Dtex rating will mean that the grass will be tougher, less friendly to the touch and will feel stiff and rough. So, it is important to find a balance between durability and user friendliness.
What is a good Dtex Rating
Dtex ratings between 6,000 and 12,000 are good for domestic and medium duty commercial applications. Higher ratings are available, but ironically the higher the Dtex rating the more artificial the grass starts to look, and the harder and less friendly it feels.
At LazyLawn we believe that it’s important to know what the Dtex rating is, regrettably most supplier do not quote Dtex ratings so you may have to depend on how the grass feels.
What does Pile Height mean?
A tuft of artificial grass is a collection of yarn fibres that collectively make up one stich in the grass backing. Generally between 10 and 14 strands per tuft.
The Pile Height is the average height of each upright blade of grass, in a tuft, if standing straight upright. LazyLawn incorporates 12 to 16 strands of 4 different colours of yarn in each tuft, some of which are light-coloured curly yarns which are designed to sit down at the root of the tuft, to look like dead grass (for authenticity).
What do Gauge & Stitch rate mean (Density)?
It is the Gauge and Stitch rate that defines the Density of grass and it is this that largely defines the quality of the grass. So, make sure that you know what the density of the grass you are buying is, before committing to a purchase, and compare these against other products in the market.
When Artificial Grass is stitched to the backing it is done in straight lines. The distance between these lines is known as the Gauge. The combination of the Gauge and Stich rate is what how many stitches (or tufts) there are in a square metre of grass.
In simple terms the higher the density of the grass the better the quality (and generally the higher the cost).
Premium quality artificial grass should have a density higher than 14,700 stitches per square metre. Cheap artificial grass tends to have densities around 6000 stitches per square metre. Short pile Green Carpet type grass has a much lower density.
What constitutes a quality backing?
Backing consists of woven fabric, which is reinforced with threads and has added layers of Latex rubber to ensure stability of the finished product. The backing has to be resilient to the variety of weather conditions that we experience in South Africa, including rain, wind, strong sun and frost.
During the manufacturing process to secure the artificial grass fibres in the backing, a liquid mixture is spread across the back. This mixture is usually made of latex. A good thick latex is essential to ensure the blades of grass remain fixed in place for a long period of time. The backing used by LazyLawn is a superior high-quality Latex rubber Styrene-Butadiene.
The backing is fitted with drain holes (generally 50 per m2) to ensure that water can drain through the grass when installed on an earth based.
