The concept of ‘going green’ has gained significant traction in recent years, particularly when it comes to home improvements. One of the most efficient methods to save energy, money, and reduce our carbon footprint is by ensuring our homes are well-insulated. By applying some simple DIY tricks, you can create an insulated home that conserves energy.
Understanding Energy Loss in Homes
A comfortable home environment does not only depend on an efficient heating and cooling system but also how effectively the home can retain the controlled temperature. Uninsulated or poorly insulated houses are synonymous with substantial energy loss, contributing to an overworked air conditioning or heating system and, consequently, high energy bills.
Heat loss or gain in homes primarily occurs through conduction, convection, and radiation. For instance, during the cold winter months, the heat in our homes escapes through walls, roofs, windows, and doors to the outside cooler environment. Conversely, during the hot summer, the heat from outside is conducted into our homes. Ensuring your home is well-insulated can help reduce these heat exchanges, conserving energy significantly.
Adding Insulation to Walls
One of the main areas for heat loss or gain in a home is through the walls. Fortunately, insulating walls is a manageable DIY project that provides an excellent opportunity for energy conservation. There are different types of insulation you can use, such as fiberglass, cellulose, or spray foam.
Fiberglass insulation, available in batts or rolls, is the easiest to install without professional help. It requires measuring the space between the studs and cutting the insulation to fit. Staple the bats into place, ensuring no spaces are left for air to seep through.
Cellulose insulation, although a bit more complex, is another great DIY option. This insulation is blown into the wall cavities with a rented insulation blower. The dense pack technique used provides exceptional insulation, preventing both air and heat movement in and out of the house.
Improving Attic Insulation
Another main culprit for energy loss is the attic. During winter, heat naturally rises in your home and escapes through the attic. Conversely, in the summer, heat permeates into your home from the hot roof.
Using spray foam insulation is a great way to handle attic heat loss or gain. This insulation both insulates and seals air leaks, providing a value of R6 per inch of thickness. Though its installation may seem complicated, it’s an easily followable process that you can DIY following safety precautions, including wearing proper personal protective equipment.
Sealing Windows and Doors
Windows and doors can be significant contributors to energy loss in a house. While full replacement might bring the highest energy-saving rewards, it’s not the only option. Simple weatherstripping can seal the gaps responsible for drafts, while a window film can act as a barrier to radiant heat. Additionally, hanging thermal curtains can provide an extra layer of insulation.
Sealing and Insulating the Basement
A significant amount of a home’s total heat loss happens at the basement level. Therefore, adding insulation to your basement walls can help conserve energy. The rigid foam insulation board is a great option for basement walls since it resists moisture and is easy to cut and install.
Applying Radiant Barrier in the Attic
A radiant barrier, a type of insulation that reflects heat, can significantly decrease cooling costs in hot climates. It works by reducing the radiant heat transfer from the underside of the roof to the other surfaces in the attic.
Installing a radiant barrier is a simple process. The radiant barrier is usually a film attached to an air infiltration barrier that you install directly onto your roof sheathing. Most radiant barriers come with a reflective side and a non-reflective side. Ensure the reflective side faces the roof.
Investing in a Smart Thermostat
A smart thermostat can learn your schedule and preferences, making your house comfortable when you’re home and saving energy when you’re not. It can conserve energy by heating or cooling your house only when it’s needed.
Air Sealing Your Home
Air leaks around holes and cracks can be a major source of energy loss. Using caulk or weather stripping to seal air leaks around movable joints, such as windows or doors. Expandable spray foam is great for sealing larger gaps around windows and baseboards.
Insulating your home is an effective way to reduce energy consumption and save money on utility bills. Most of these suggested projects are simple enough to DIY, proving that you don’t always need to invest in major renovations to improve your home’s energy efficiency. The trick is knowing where to focus your efforts for the most significant impact.
With these DIY tricks, you’re well on your way to an insulated home that’ll serve you well year-round, keeping you warm in winter and cool in summer while conserving energy and saving money. Additionally, these small steps to a more sustainable lifestyle are every homeowner’s contribution to a safer and healthier planet.
