Artificial grass is very durable and when installed correctly can withstand all UK weather variations, however, during the summer months (and heatwaves) the grass surface, in some cases, is susceptible to damage through extreme temperatures.
As part of a site survey you or your installer should look out for any potential hot spots We have listed the main factors below.
They have a large surface area for sunlight to reflect off for a sustained period. You may notice burn marks on the lawn as a result. To solve you need to install a protective film to the window(s).
Any item in the garden with a shiny surface could pose a risk to the lawn. This includes but is not limited to mirrors, planters, ornaments, water features, gutters, light fittings etc which can reflect sunlight at a high intensity.
On doors, sheds, outbuildings etc. These can also have a big surface area which light can reflect off for a long time to cause damage on the surface.
Either through vandalism, stray embers from a barbecue or fireworks and cigarettes. This kind of intense heat applied directly onto an artificial lawn can burn and melt the grass.
Synthetic turf can melt through the direct application of left heat on the surface. Anything that generates heat left directly on the grass e.g. hose pipes (water inside being heated), metal garden furniture, garden tools such as hedge cutters, blowers and mechanical brushes etc.
Finally, rolls of grass should never be left uncovered in direct sunlight/extreme heat as this can cause the black backing to become very hot and damage the grass through several layers. Always make sure that the roll is covered by a tarpaulin or similar.
You can sometimes repair a small patch if required so we recommend keeping any off-cuts from your lawn project should you need to do this in the future.
In very hot weather & heatwaves yes, artificial grass does warm up.
Please reassure the customer, however, in our tests, after 2 hours the surface gets to approx. 41.2 degrees. In these instances, like most surfaces will in periods of hot weather common sense is advised, e.g. putting on shoes, slippers or flip flops before walking on the grass or using a blanket to sit on, lightly hosing the grass with cool water.
In 35 years trading, we haven’t had a case of any injuries due to heat. The products are widely used across Europe in much hotter temperatures too.
