How To Take Care Of An ETFE Cushion Roof?


ETFE cushions have a smooth surface, which means lesser opportunities of dirt to be retained on the roof surface. And, during the rainy season, all forms of dirt and bird droppings are easily washed away. This means that there is less maintenance required when it comes to the aspect of cleaning such roofs as compared to other traditional roof surfaces. However, this does not mean that you don’t at all need to look after the cleaning as it is a self-cleaning material. No material is entirely self-cleaning; and same is the case with ETFE cushions. So, here are some steps you need to follow when it comes to maintaining your ETFE roofs.

External cleaning

Because it is not entirely, but is to a large extent highly self-cleaning, you needn’t clean your roof every half or full-yearly, but make it a point to have it cleaned externally every 2-3 years. Especially, when you live in a city full of vehicles, smoke, and pollution, you need better and more careful maintenance and cleaning of the exterior of your roofs.

Internal cleaning

Cleaning your roofs is not limited only to the outside; it needs cleaning on the inside too – although far less frequent as that on the outer side. Depending upon the dirt collected in the internal environment, you will have to get your roofs internally cleaned every 8-10 years. You may see roofs not needing underside cleaning for their entire lifetime, but there is no harm in spending a little time, money, and effort once in 8-10 years, is it?


The above mentioned maintenance is restricted to only the aspect of cleaning. Now, let us come to the maintenance regarding the functioning of your roofs. The cushions and inflation units should be serviced every year to make sure that the roofs are functioning as they should be. After all, the main purpose of ETFE is to provide insulation, transparency, warmth, protection, and to resist wind loads. Multiple layers of ETFE are inflated with low air pressure to provide all the above functions, thus proving best for humidity-controlled environments. And, if there are any holes, leaks, or damage in the cushions, it will start to deflate, thus ruining it’s functioning. Therefore, you must check for any visible damage to the internal and external foil layers of the roof, and also the distortion of their shape. Also, the capping elements, welded joints, plenum and associates joints, brackets, clamps, and other connections must be checked for integrity, fixity, and leakage. Any kinds of even the most minor holes and tears should be repaired, and damaged or worn-out parts must be replaced. The best part about replacing the damaged areas of an ETFE cushion roof is that if only a single cushion is damaged, it can be individually removed and replaced, without disturbing the rest of the roof!
