Prevent Window Air Leaks and Maximize Energy Efficiency

Sealing air leaks, along with good insulation, is the fastest and most cost-effective way to keep your energy bills down.

Air leaks work against your home’s energy efficiency in that it lets heat escape from your house during cold days and lets the heat in during warm days. Consequently, your HVAC system is forced to work more than it should, resulting in higher energy bills.

Imagine your house is a sealed box. Every time you cut an opening – a door here, a window there – the less sealed the box becomes. It’s impossible to live in a box-like structure, so the next best thing is to ensure that every opening — door, window and vent — is designed to minimize air leakage.

Windows are one of the biggest openings in the house, after doors. They provide views, daylight, ventilation, and solar heat during winter. They can also account for as much as 25% of your heating bill if not built well and installed properly.

If you are looking into new San Francisco window installation, look for energy efficiency features such as:

• It must be ENERGY STAR®-certified. The glass should have an ENERGY STAR label attached to it, and should be visible after window installation in San Francisco.
• It must have at least two panes of glass and low-e coating. This will minimize the chances of heat being conducted from one side to another.
• It must have a low U-factor for better insulation in colder seasons. This means heat is kept where it should be: inside when it’s cold outside, and vice versa.
• It must have a low solar heat gain coefficient (SHGC) value. This means it won’t get too hot inside during hot days, ensuring less work for your AC.
