Cutting down on household expenses is one of the many ways a person can save money. Luckily, there are a bunch of home improvement projects that can prevent energy loss and help you save money in the long run. If you’re concerned about skyrocketing heat and cooling bills due to changing weather, then you might want to invest in installing Low-e glass into your windows.
When the air inside of your home escapes outside, or cold drafts and desert winds enter your home, your air conditioning and heaters will have to run more to keep your house at a consistent temperature. This can really drive up your energy bills.
Your windows in particular are susceptible to large amounts of energy loss. While experts estimate that 70% of all energy loss is due to poorly insulated doors and windows, 90% of window heat loss is through the window glass. If you live in a cold climate, the wrong type of glass will let heat escape outside. However, if you live in a warm environment, infrared and ultraviolet light will enter through the glass and not only heat-up your house, but also fade your upholstery and wall trimmings.
So, what is low e glass? Low-e, or “low emissivity” glass, is the energy-efficient solution to this problem. It has a microscopically thin metallic oxide coating. It’s transparent and heat-reflective to minimize the amount of infrared and ultraviolet light entering into your home without blocking natural light. It keeps heat from entering your home during the summer and keeps heat circulating inside your house during the winter.
To simplify, Low-e glass works just like your favorite thermos. If you have hot coffee, it will reflect the heat of your drink to keep it constantly warm. If you have ice-cold water, it’ll reflect the cold to keep your ice from melting. And it does all this while keeping outside temperatures out. Low-e glass doors will help maintain the temperature of your house while keeping cold and heat out.
There are two types of Low-e glass: hard-coat and soft-coat. Both low-e glass door options are energy efficient, but hard-coat glass (also known as passive control) had its metallic oxide coating added during production, making it hard to scratch. Soft-coat Low-e glass (also known as solar control) is applied after the glass is made, making it more delicate. Generally, both hard-coat and soft-coat Low-e glass are effective, but soft-coat has a higher thermal resistance value (R-value), meaning it is better at heat insulation.
There are a few more factors used to measure the effectiveness of Low-E glass:
We know that not every pet door out there does well in extreme weather conditions. Most are not well-insulated, the flaps are easily damaged and do not seal, and sliding glass door inserts do not protect against cold drafts.
When making our sliding glass inserts, we made sure that our pet door has the greatest energy efficiency value out there. Not only do our flaps have an airtight magnetic seal and our frames are lined with insulating weatherstripping, but the glass we use in the majority of our sliding door and window panels has a Low-e coating.
