We understand that artificial grass is an investment that is expected to last for years to come. So we have come to expect enquiring customers to approach us with an array of questions about our products and their requirements, one of which being ‘Can artificial grass melt?’. Put simply, in extreme cases, yes. Now with temperatures set to rise once more this summer, we felt now would be the best time to raise awareness about the factors which can potentially contribute to artificial grass melting.

How can artificial grass melt?

The technology required for manufacturing artificial grasses has improved vastly over the last 20 years. In 2021, most artificial grasses have a melting point of around 175-200 degrees Fahrenheit, are designed to withstand freeze and thaw conditions, and have a specialist backing lining to prevent the colours fading from UV exposure. The blades of artificial grass are usually made up of a combination of polyethylene and polypropylene, for its light weight and flexibility but it’s worth noting both materials are plastic based, therefore are susceptible to melting in extreme conditions. This does not mean the grass is faulty or cheap. If you find what you believe to be patches of your artificial grass fibres melting, read on to find out how to identify the cause(s) and remedy the problem.

Identifying Causes

If you discover parts of your artificial grass lawn have melted in any way, heat is ultimately the cause. Finding the source of heat is the key to preventing any further damage to your lawn. Reflective surfaces, for example windows, mirrors, polished gutters, lawn equipment and mirrored décor can all be the catalyst for hotspots of extreme heat being directed at your lawns fibres. Look out for these key signs your artificial grass may have melted: fibres fused together, fibres that have become frazzled or brown, any areas which feel particularly hot to touch. If you spot any of these signs it’s imperative you take immediate action to prevent further damage to the lawn.

Low-E Windows

In recent years the rising demand for ‘low-e’ – or low emissivity – windows has caused an increase in the number of damages reported to artificial grass as a result of excessive heat exposure. Low-E windows are specifically designed to allow light to pass through whilst reflecting both UV and infrared light (i.e. heat). This reflection can create a magnifying effect when the heat being reflected is allowed hit conductive surfaces like plants or artificial grass for an extended period of time.

Preventative Measures

Luckily there is an array of preventative measures you can take to ensure your artificial lawn stays in optimal condition for years to come. Even if your artificial grass has already succumb to extreme head conditions, this can still be remedied fairly easily if a qualified landscaper is hired to remedy the situation.

Prior to installation

The best way to prevent your artificial grass from being exposed to extreme heat is by doing thorough site survey prior to installation. Identify any reflective surfaces and check the temperature of potential ‘hotspots’ – ideally at the hottest point in the day. If you are still unsure whether an area will be suitable for your artificial grass, it may be worth laying a sample or offcut out in the desired area and monitor the results. Once potential problem areas are discussed, your landscape can be designed accordingly to ensure artificial grass is not laid in areas which may be exposed to extreme heat. Some popular solutions include: adding a garden path with pavers or gravel, including a soiled area for a flowerbed or to plant a tree, additionally larger gardens may benefit from a water feature or small pond.

Following installation

If you notice hotspots in your garden area may be causing damage to your artificial lawn following installation, the first thing to do is check the surrounding area for reflective surfaces which could be responsible for the excess heat (this includes neighbouring properties!) once identified, remove the reflective surfaces immediately. If the surfaces can not be removed, for example Low-E windows, it’s fairly easy and inexpensive to install a protective film which will limit the reflection of heat onto your artificial lawn. You may need to contact your installer to arrange a patch repair if your lawn has already become damaged. Patch repairs are not usually covered by your warranty.
