ThermaGlas Plus is made with an exclusive manufacturing process that results in one of the the industry's best condensate control mechanisms and it features a 10-year condensate control warranty. To review what causescondensation and the adverse effects it has on a greenhouse production.  Because effective condensate control is such a critical need for greenhouse growers, the "Plus" condensate control feature is now built-in to every ThermaGlas product, unless otherwise noted.
