Climatic Issues

Pennsylvania is lucky enough to experience a full range of annual weather-including hot, sunny beach weather in July, a white Christmas in December, and everything in between. Loewen windows are designed and manufactured on the Canadian prairies, built to withstand all types of weather conditions and fluctuations. In addition, Loewen offers a StormForce™ Series of windows and doors built in three grades to provide extra comfort and security from Mother Nature’s worst. In Chester County, fluctuating humidity levels are a concern, and something to keep in mind when you’re choosing building products. Learn more about the effects of condensation on windows- as well as practical tips and guidelines- at the Window and Door Manufacturers Association Web site:
