Although replacing your old windows with newer ones provide a lot of benefits, most homeowners today switch windows for its biggest advantage – improving your home’s energy efficiency. Energy costs are on the rise, after all, and air leaks from failing windows greatly contribute to it. Replacing windows helps stabilize indoor temperature in your home, keeping your HVAC system from working doubly hard and needlessly guzzling power. How does a replacement window achieve energy efficiency exactly? It’s thanks to the sum of its parts.
What a lot of people don’t realize is that windows also let in heat alongside natural light. When too much heat is let in, it becomes a problem because it makes it harder to cool a home. Multi-pane window glass addresses this problem by limiting the amount of heat that passes through. This is why double-glazed windows have better thermal performance than single-glazed windows.
Part of the reason why multi-pane glass works is the space between the glass panels. Air within that space is replaced with an inert gas, which works to further prevent heat transfer and improve window insulation. Many manufacturers use argon gas but xenon is also an option.
Some replacement windows have frames consisting of two main parts: the outer surface, which could be made of vinyl, metal, or wood, and a “core” consisting of foam. The foam core has plenty of air pockets that work just like the gaps between multi-pane glass, absorbing heat and reducing heat transfer. Foam is also a lightweight material so frames remain functional without the heft when it is used.
Airtight Frame Seals
Window frames can offer great insulation on their own, depending on the material they are made from, but they won’t be as effective if they don’t feature airtight seals. Filling the gaps between the window frame and glass, seals help ensure that air leaks don’t occur. As they must keep up with the window, seals must also be durable enough to withstand wear and tear for years.
