In the world of greenhouse construction and horticulture, where efficiency and sustainability are essential, sandwich panels now come with a new waterproof coupling. WNL Horti Insulation is its inventor. The name of this patented coupling is Easyjoint.
Czander Dubbeld, co-director WNL, explains that it is fundamentally designed to reduce installation costs and provide a safe, durable, and waterproof solution for sandwich roofing systems, "Caulking is no longer necessary; the joint is designed to be wind and waterproof." Gert Hollaar, founder WNL Horti Insulation, saw a need for this: "Labor is scarce. Quality is required. The two are now combined. We have been able to 'translate' that into Easyjoint." 
The rubber slats at the top stop water from outside. And the gutter at the bottom drains condensation water.
Recently, WNL celebrated the opening of its new premises. In case you were not there, here are some photos to get an impression of the production hall.
