5 Reasons why you should replace your windows
New Science: Your upgrade should bring you abundant light, fresh air, soundproofing, and decorative beauty. Advanced technology has discarded the use of highly conductive metal materials, like perimeter spacers made of aluminum or steel. Instead, thermo-set rubber spacers - made entirely from polymer structural foam - deliver not only precise indoor environment control, but also superior sound insulation, as well as suppleness to create and window shape and size. Perhaps more importantly, foam spacers help control condensation, which is a trigger for unhealthy mold growth.
Lower Energy Bills: To reduce heat loss, look for a "no-metal" component and for units made with glazed glass, argon gas fills and low-e coatings to conserve the radiation of heat and light. Energy efficient windows and doors control home operating costs.
Help Conserve: High performance windows and doors with durable materials help to cut back on energy use. To maintain the warmest overall surface temperature, avoid metal materials as mentioned above. The all-foam, Super Spacer for example, conducts heat (and cold) at a rate over 950 times lower than aluminum and 85 times less than stainless steel
Top Quality: For long-lasting durability along window edges, avoid metal, but also avoid plastic. Spacer material must allow expansion and contraction at the edge of the glass. The ridgity of plastic can cause seal failure and it can literally crack the glass edges on extremely cold or hot days.
The Environment: High performance windows conserve energy and therefore help to reduce polluting greenhouse gas emissions. Durable window materials will last longer and minimize future waste.
