Working at Cocoon is not just something. It is special, varied and cannot be explained in 1 sentence. Jed Lee, who has been with us for 11 years, shares his experiences as a Cocoon technician.


Can you tell us something about yourself?

“My name is Jed and I joined Cocoon in 2008, through my colleague Richard.. Before this I worked for more than 2 years as a lift / reach truck driver, but I was looking for more variety and challenge. And I have certainly found that and more at Cocoon. I started in 2008 and after 6 weeks I already went to Japan, Korea and Thailand to carry out projects there.”

“When I just started working, I didn’t know the product well. I now have extensive experience and have been able to do a wide variety of projects. When someone asks me like at a birthday party or so, what kind of work I do, it cannot be explained in 1 sentence, it is too special for that. I get puzzled looks when I try to explain all the things we can do.”

What exactly do you do at Cocoon?

“I am one of Cocoon technicians meaning I apply the Cocoon (flexible PVC coating) via our spraying method. Together with my colleagues we do very nice projects, where we often make use of Cocoon for sealing seams and making spaces airtight. We do this at hospitals, laboratories, but also many special projects such as in high voltage pylons and at the Amsterdome. Or like with our latest project Iter.”

“I have always found Cocoon a very special product. Take, for example, what we call ‘webbing’. Then we spray spider web-like strings with a certain spray gun (which has been set correctly), so that we can bridge and close openings and / or holes.”

What is the most recent project you have done?

“I also think our most recent project is our most special project, namely the Iter project. It has been ongoing for the past 2 years and we have spent a total of 6 weeks onsite in France with 4/5 colleagues.”

“Alexander, Richard and I went to France earlier to make the preparations. We first laid the entire piping system on the cryostat, with the aim of dehumidifying. A week later the other team arrived and then we all stuck the large sheets of foil onto the cryostat. These pieces of foil weigh as much as 350 kilos each and we made this in advance in the Netherlands. With our own hoisting system, we attached the foil to the steel construction with our own primer.”

“After the sheets were hung and the cryostat was transported outside, we could start finishing. That means spraying the seams and applying the thicknesses. Finally, we connected a drying system so that we could continue to follow the statistics from Amsterdam.”

Which assignment has made a lasting impression?

“Then I immediately think of a project in Korea. We carried out work there for 8 weeks. Architect Rem Koolhaas designed a steel frame for the LG, Prada and Hyundai brands so that they could hold their exhibition there. The steel construction had different views: hexagon, cross, rectangle or square.
The construction was always rotated by means of 4 times 400-ton cranes. These literally came to lift the structure and turn it to a different view. We were allowed to provide the construction with a seamless and transparent Cocoon, because daylight had to shine through and so it could give the construction a lively effect. In this case, our Cocoon was not only functional, but also aesthetic.”

“Another nice project was for TenneT. There we were allowed to seal the seams of the high-voltage pylons from Beverwijk to Berkel and Rodenrijs. The special part of this was having to work at a height of no less than 70 meters. We were trained by IRATA for this. For 2.5 years we climbed in the masts to seal seams.”
