It depends on what you’re looking for.
Both 30mm and 40mm thicknesses are a good option for upgrading your garden space, and so selecting between the two should depend on preference, available budget, and the requirements of your garden.
Typically, you will find that a grass roll becomes more durable and authentic as the thickness increases. However, shorter pile grasses can be a great solution for family use or homes with pets. You’ll also notice a mixture of options in 35mm and 38mm, as an ideal mid-way compromise.
When it comes to artificial turf, the thicker the better, and our 40mm thick grass is generally the most popular choice with customers looking to transform their garden space. Our ranges are extremely durable, keeping your lawn looking fresher for longer.
