We first deliver an energy calculation and proposal based on drawings or window photos; the on-site survey is scheduled per project — distance never slows the decision.

Process: free on-site measurement → energy calculation report → factory fabrication → professional installation & acceptance · Lead times are typical schedules, subject to project assessment.
