One of the best ways to insulate an exterior wall is to clad it with rigid polystyrene foam. This insulation can attach to a wall and hide under siding, or adhere directly to a concrete wall that is free of cracks or any signs of moisture. Structural insulated panels were a major advancement in post-and-beam and timber-framing insulation. These panels are essentially two pieces of OSB with a thick piece of foam in-between, and they provide strength and insulation for open wall space that might not otherwise have any. They feature tongue-and-groove connections, and installers can run electrical wiring, pipes, and other utilities through the foam.
This system creates walls with a high thermal resistance, typically about R-20. Even though ICF homes are constructed using concrete, they look like traditional stick-built homes. It is more effective to install insulation over the surface of the blocks either on the exterior or interior of the foundation walls. Placing insulation on the exterior has the added advantage of containing the thermal mass of the blocks within the conditioned space, which can moderate indoor temperatures. It is important to know which material would work best for your individual home and lifestyle. Overall, insulating your home is an efficient choice and will benefit you, your wallet, and the environment.

An added bonus on top of this ultimate heat insulation is that it works as an excellent sound barrier. You can block out any unwelcome sounds when using this radiant barrier. Moreover, the polythene layers make the panel strong and will protect it from damages and mice problems. It’s 24 inches by 50 feet, giving you a lot of insulation to work with, and with it being so lightweight, it makes installation easy for any homeowner.
Cellulose is one of the oldest insulation materials available on the market. It can be either installed as loose-fill on the attic floor or as a blown-in material. As the ThisOldHouse.com experts affirm, there are many ways to retrofit a house with insulation.
Blanket: Batt and Roll Insulation
Creating an air barrier with insulation can block air movement throughout the home. That air barrier will prevent air leakage into and out of your home, which can account for nearly 30 percent of a home’s heating and cooling costs, according to the U.S. In our honest opinion, insulation should be properly installed by a professional to ensure the peak performance of the materials. So, if your attic doesn’t have good insulation, it will allow heat to escape through the roof. According to the Department of Energy, homeowners can save between 10 to 50% of their average heating bill when insulating their attics. It’s an essential way to reduce heat loss — which in turn helps lower your energy bills and stops your pipes from freezing in cold weather.
When touched, it can irritate the skin and eyes, becoming very itchy and uncomfortable. If inhaled, the small fibers can become lodged in the lungs, causing serious respiratory issues. While this may be an issue mainly for the person installing or removing it, those fibers can also get pulled into your air ducts. It features the thickest EPA foam insulation available (up to 1.5 inches).
Q. What is the best insulation for walls?
It is intended to help add insulation in hard-to-reach areas of existing insulation or to seal leaks or gaps in areas at risk of air leaks. If you are looking for some organic way to insulate your home, cellulose insulation will work best for you. This type of insulation is mainly made from recycled paper, mainly newspapers and sometimes cardboards and other kinds of papers, and comes in loose fills. Cellulose insulation materials are treated with chemicals to make them better in protecting the home from moisture, heat, and pests. Some less common loose-fill insulation materials include polystyrene beads and perlite. Loose-fill insulation can be installed in either enclosed cavities such as walls, or unenclosed spaces such as attics.
This affordable radiant barrier features two foil-faced sides and a closed-cell foam to provide insulation and fire resistance. It depends on the type of insulation you have and the condition of the insulation. If you have fiberglass batt insulation and it looks to be in good shape, you can add new insulation without removing the old insulation. However, do not place faced insulation on top of existing insulation because the face or paper part of the insulation can trap moisture and lead to moldy insulation. Those who have used Knauf Insulation ECOROLL love it and report little to no itchiness when installing it. Some, in fact, think it has a better consistency than competitors.
Spray Foam Insulation
Foam board insulation is offered in multiple varieties, but the most common are Expanded Polystyrene , Extruded Polystyrene, and Polyiso . When installed according to manufacturers' recommendations, SIPs meet all building codes and pass the American Society for Testing and Materials standards of safety. Today, most foam materials use foaming agents that don't use chlorofluorocarbons or hydrochlorofluorocarbons , which are harmful to the earth's ozone layer. Obtain written cost estimates from several contractors for the R-value you need, and don't be surprised if quoted prices for a given R-value installation vary by more than a factor of two. Insulating your home will have outstanding comfort and energy efficiency impacts for years to come.
However, a very experienced DIYer may find their installation manageable. They’re also built to order, so DIYers determined to install their own will have to contact a shop or retailer to place an order. TAP’s Registered PEst Control Blown–In Insulation is made from cellulose and has an insulation range between R19 and R60.
Fiberglass insulation is one of the best options for soundproofing your home. These two are both top-notch insulations for absorbing sound by preventing it from traveling through the air. The R-value of insulation tells you the amount of heat flow that is resisted by a material.
Nothing beats the toasty feeling of sitting in front of the fireplace in winter or the cool of the A/C during a long, hot summer. A well-insulated house will make sure you get to enjoy both, and it will help ease the pain you might feel in your wallet at the end of the month.

Insulating outside of concrete block wall places mass inside conditioned space, which can moderate indoor temperatures. Fiberglass is another traditional form of insulation found in many homes across the country. While it is the least expensive option, which makes it attractive, it is the least effective. Let’s take a look at the best insulation for new construction homes starting at the top of the house down to the bottom.
