Here in the South, humidity makes it tough on windows. In fact, 25% of all the energy used for heating and cooling is lost — literally. Leaky windows and heat flow mean rising energy costs each month — drafts in the winter and rising temperatures in the summer. LAS Weathergard windows will eliminate air leaks and keep those utility bills in check. Low E-glass reflects 40% – 70% of the sun’s energy right back where it came from, and that means your home will stay cooler.
