Time to Upgrade - Greenhouse coverings
Sibylle Viz of Roehm explains the importance of upgrading your greenhouse coverings.
The whole idea behind a greenhouse is that the plants are indoors and covered, so whatever material a grower is using to cover their greenhouse is crucial.

But, if you haven’t updated your own greenhouse covering in a while, you could be missing out on some of that precious sunlight that’s supposed to be coming in through the roof.

Stretched ACRYLITE® Meets Quality Specifications
February 07, 2020
Successful MIL-P-25690 Qualification for Stretched ACRYLITE®
- Stretched ACRYLITE® meets the quality specifications of the US standard MIL-P-25690B for Class 2 (improved moisture-resistant) material.
- Material particularly suitable for use in aviation
- Produced in the world’s most advanced acrylic production plant in Weiterstadt, Germany
Stretched sheets of polymethyl methacrylate (PMMA) from POLYVANTIS are qualified to MIL-P-25690B in sheet thicknesses up to 0.800” (20.3 mm). The qualification attests to the material's chemical resistance, impact strength (for example, against bird strikes), resistance to cracking, and fulfillment of optical requirements.
PMMA has been used for decades in areas of the aviation industry where the highest requirements are placed on the material. These include passenger cabin windows, windscreens, and cockpit windows.
The sheets are produced and stretched in Weiterstadt, Germany. In 2018, to meet the demand for materials for the aviation industry, our Acrylic Products Business Unit started up the world’s most advanced production facility for stretching PMMA. The plant produces sheets up to 5.0 m x 3.0 m (200” x 120”), which is double the current industry size. Since the end of 2018, the first customers in the aviation industry have been supplied with samples of the new material.
As Falk Majert, head of the business unit, explains: “With this successful certification, we are consolidating our position as a leading supplier of aviation materials and a driver of innovation in the sector. We offer the customer cast and stretched PMMA of the highest quality from a single source. With the now certified stretched material, we’re opening up new design and innovation options, and thus also further growth prospects, for customers.”
