Unless your home was built especially for energy efficiency, you can probably lower your energy bills by adding more insulation. Many older homes have less insulation than houses built today, but even adding insulation to a newer home can pay for itself in a few years. A properly insulated basement can save you money on heating and provide a dry and comfortable living space. In most cases, an insulated basement installed on its outer walls should be considered a conditioned space.
Even in a house with an unconditioned basement, the basement is more connected to other living spaces than to the outside, making basement wall insulation preferable to roof insulation. For most homeowners, it pays to upgrade a home with poor insulation. It is an improvement that will pay off both in reducing energy bills and in improving the value of housing, and it has the additional benefit of reducing greenhouse gas emissions. Take the time to evaluate and develop a plan that will allow you to have a properly sealed and insulated home.
When combined with a proper air seal, the insulation contributes to additional savings in heating and cooling costs. Properly insulating your home also allows for a quieter space from outside noise. Any surface in your home that separates the interior from the outside must be insulated. There are several ways to properly insulate your home, depending on your budget and level of comfort with projects related to home energy.
Yes, building a house with better insulation costs more, but that's only half the equation. It also costs less to operate and additional construction costs can be instantly offset by savings on heating bills. So there's more money in your jeans at the end of each month, starting right away, and tons of tons waiting for you at the end of your mortgage. The location of your home that needs insulation can also greatly affect the overall cost.
To be as energy efficient as possible, a house must be insulated from top to bottom in areas such as the garage, basement, attic, roof and walls. If done correctly, air sealing and insulation work hand in hand to reduce the risk of moisture-related mold and rot, increase interior comfort by eliminating drafts and reducing outside noise, among many other benefits. A basement doesn't usually need as much insulation as the rest of the house, since the surrounding land helps keep the area cool in summer and warm in winter. This type of insulation is designed to fit the standard width between wall studs, beams and beams, making it incredibly easy to install, especially before walls, ceilings and floors have been sealed during the construction of a new home.
A ventilation deflector must be installed between the insulation and the roof cover to maintain the ventilation channel. If radon is a problem where you live, you'll also need to consider radon- and radon-resistant construction techniques when researching foundation insulation options. The best way to determine if your insulation is up to par is to evaluate the existing insulation (its type and thickness) to compare its R value with that of the U. When it comes to insulating an old house, there are some misconceptions about the need, the cost and the best way to complete the process.
If you're remodeling and your wall cavities will be open, look for two-part spray foam or wet cellulose spray insulation. Foam board, or rigid foam board insulation, is best for insulating the outside of your home and is installed under siding. If you are in a conditioned part of the house, remember to also insulate and seal the access to the attic with air. How well it does it is measured by a number called the “R value”, and the higher the number, the better the insulation will be to resist heat transfer, assuming it is installed correctly, that is.
If you have or will have an unventilated mezzanine, it's best to seal and insulate the foundation walls rather than the floor between the mezzanine and the house. This will largely depend on the amount of current insulation in existence and on the severity of energy leaks throughout the home's thermal envelope. In unfinished attic spaces, insulate between and above the floor beams to seal the living spaces below. You can request hemp insulation through Ecohome, and hemp is a natural, non-toxic insulating material that will protect your home's air quality.
