Building More Than Just Homes
Nagy Bros has deep roots in the Okanagan and for the last 30 years the Nagy’s have thrived in the blistering heat the Okanagan brings each summer. Our team of window experts has over 100 years of fenestration experience and comes from all over BC. The Okanagan’s heat and winter temperature swings require windows that provide both excellent solar heat mitigation while providing great insulation for the winters. BC’s dense costal region excellent wind and water ratings and drainage systems. Windows in Northern BC require excellent U values, reinforced frames and additional weatherstripping. Our team of experts is trained to provide the best comfort, efficiency and value for every project.
