Rigorous testing
All Decko products are subject to a gauntlet of tests, not only to ensure their superior quality, but to guarantee that they meet or exceed applicable industry norms. Our various models undergo minute examination in order to evaluate their imperviousness to air and water leakage, wind-resistance, deterrence to forcible entry and thermal-retention—all closely monitored at our on-site R & D testing facilities. We can thus guarantee that our patio doors will satisfy the strictest of building codes and stand out for their maximal energy efficiency.
