People often complain about high energy bills and drafty, uncomfortable living spaces. Wouldn’t it be nice if you could drastically reduce those bills and feel warm and cozy inside your home without having to put on an extra sweater? In this blog, you will learn how to do just that! Did you know…
On average, windows and doors account for 35-40% of a home’s heat loss in the winter, and an even larger heat gain in the summer – according to the Minnesota Dept. of Commerce website.
The US Department of Energy reports that an average household spends 40% of their annual energy budget on heating & cooling costs.
Energy costs in US homes could be reduced by up to 15% by installing more energy efficient windows – US Department of Energy.
What makes a window energy efficient?
- U Factor – Measures how well a product prevents heat from escaping – the lower the U Factor the better the insulating value. Look for a rating of 0.20 – 1.20.
- Solar Heat Gain Coefficient (SHGC) – Measures heat blocking capabilities of a window – the lower the number, the better the product is at keeping out the heat of the sun. Look for a number between 0 and 1.
- R – Value – Also measures resistance to heat loss – however, in the case of windows the U Factor and SHGC are more important measurements.
- Proper Installation – It is very important that windows are measured, installed and sealed properly to prevent air and water leaks which reduce the effectiveness and lifetime of your energy efficient window. Hire a professional – the extra money you spend up front could save you from a multitude of costly mistake.
When should you consider replacing your windows?
If you feel a draft of warm or cool air coming through your windows
If you see peeling paint on exterior of house
If you notice frost or ice build up on your windows during the winter months
Simple tests you can do yourself to check for inefficient windows:
Soft or rotted wood – Gently tap the window frame with a screwdriver – if pieces of the wood are extra soft or break off, you may have rotten wood.
Caulk or seal failure – Use a flashlight and shine it around the edges of the window from the outside of the house. Have someone inside who can tell you if any light were seen coming through the other side.
Tests you should hire a professional to perform:
Blower Door Test – This test is used to measure the airtightness level of building envelopes, diagnose and demonstrate air leakage problems, estimate natural infiltration rates, estimate efficiency losses from building air leakage, and certify construction integrity – The Energy Conservatory website -As stated previously, windows and doors can account for 35-40% of this air leakage
Infrared Testing – An infrared camera is used to sense hot and cold spots and detect any air or water leakage around windows. -This test is also good for detecting faulty building insulation and leaks anywhere in the home that cannot be seen by the naked eye.
