A well-insulated home is comfortable, energy-efficient and eco-friendly, which makes proper home insulation a good investment. Read on as general contractor 3JM Exteriors, Inc. shares some tips about how to improve your home’s insulation.
Understand Why You Need Home Insulation
We’ve established that home insulation is a good thing, but not many people ask why, or how it works. Every home has an enclosure called the energy envelope, which consists of the attic, exterior walls and fenestrations: windows, entry doors and skylights. All of these components are insulated in one way or another, which creates an enclosure that is designed to reduce heat transfer.
Heat tends to move towards spaces with lower temperatures. In an uninsulated enclosure, this means heat can escape during cold days, while it can intrude during hot days. With insulation, the indoor temperature stays more or less the same, regardless of outdoor conditions. This reduces the need for the HVAC system to compensate for the temperature difference, resulting in energy savings.
Plan Your Insulation Upgrades
Many homes are “built to code,” which means the home insulation, particularly in the walls, have the minimum insulation as required by local building codes. This means there’s very little headroom in case it gets too hot or too cold outside. Even if you have purchased and installed the most energy-efficient replacement windows, they won’t perform as expected if the other parts of the energy envelope are not properly insulated.
It is, therefore, important to plan your insulation upgrades accordingly. Working with a contractor who performs home energy inspections can be beneficial. A full assessment of your home’s energy efficiency lets you pinpoint problem areas, which lets you set your priorities.
Inspect the Labels Before Upgrading
Energy ratings are common with electronics, but they can also be found on replacement windows and entry doors. It only makes sense to check the energy rating label if your aim is to improve your home’s energy efficiency. One of the ratings you should pay attention to is the U-Factor, which how much heat can pass through a particular product. The lower its value, the better.
You may find R-Value in place of U-Factor in some products, and it’s important to know the difference: R-Value indicates heat resistance, therefore, a replacement window with a low U-Factor will have a corresponding high R-Value.
