What is single ply?

What is single ply? Single ply is a thermo plastic material. It comes in rolls 2 meters wide and 20meters long. It is welded together using a hot air gun that fuses the thermo plastic material together giving a weld that is stronger that the material itself.

Why use the Envirotech EVA single ply waterproofing membrane?

Envirotech EVA single ply membrane has proven itself as a first class product. It has been on the market for 20 years and over 50million m2 has been installed in that time. Some of the benefits of Envirotech EVA single ply include the fact that it is a roofing material that looks good and gives a sleek modern finish.

It is exceptionally durable which gives it a long life span, in excess of 25 years. The seams are heat welded together meaning that the roof acts like one monolithic sheet on your roof. The material is flexible so if there is any slight movement between the roof and the walls the single ply will move with it.

Is single ply a new product?

No. Single plys have been in the market for over 25 years now but only recently has it become more widely available. Over the last 25 years just like all new products a lot of research and development has gone into them and these modern materials offer numerous advantages over other traditional waterproofing systems.

How much will it cost?

Unfortunately there is no straight forward answer to this question and the price depends on several things including size of roof, height, complications, whether the roof is in reasonable condition or in need of complete replacement.

However Envirotech EVA single ply membrane is a competitively priced waterproofing system. The product itself is of an equal price to the better quality waterproofing systems on the market place, but beware there are many different types and qualities of waterproofing.

What other waterproofing systems are there and why choose single ply?

There is a range of waterproofing solutions available to property owners now. It used to be in the past that the only product available was bituminous felt roofing, but as with most building materials over the last few decades there have been huge advances made, and now improved waterproofing products are now available.

Each product offers and promotes benefits over one another but undoubtedly single ply is by far the most widely used flat roofing waterproofing system in the new building sector today. The reason for this is that it has proven over the last 20 years to the industry, professionals and clients that it is simply the best solution.

Single ply membranes are the most widely used flat roofing material in the new build commercial sector today but only recently have they become more available to the domestic and refurbishment market place.

Single plys have proven to Architects, Surveyors Engineers and Builders that they have many benefits over other flat roofing products such as felt.

Is it environmentally friendly?

Envirotech EVA contains no volatile organic compounds (VOC’s) which can leach out of some other PVC single ply products, making Envirotech EVA more environmentally friendly. The amount of plasticizer used to produce the product is far less that other single plys which is better for the environment and the product can be readily recycled.
