Earlier this year Coulisse B.V., world-wide supplier of window decoration, took over the double roller blind division of JTB Sunprotection GmbH from Ganderkesee, Germany, supplier of interior sun protection. With this take-over Coulisse extends its offering in systems and collections for this innovative and growing product group with new hard and software. With this development Coulisse offers the market an even broader and complete range which allows Coulisse to serve the increasing demand for this new roller blind variety even more adequately.
