If you feel you're hitting something soft and pillowy, you've got insulation. If you immediately hit something hard, you're probably bumping into a wall stud -- try the other side, top, or bottom. If you can wiggle the skewer around and touch it to the inside face of the exterior wall -- bad news, no insulation.
These days, it's strange to think of a home with no insulation. However, insulation is a relatively recent feature for residences, and homes that are 60 years or older might not have insulation.
The vast majority of houses have some sort of insulation, but homes built before the 1970s tend to not have enough insulation. If you think you may need more insulation, call the experts at OJ Insulation! We have been insulating Southern California homes for decades. Contact us today to learn more!
Based on new research, the North American Insulation Manufacturers Association (NAIMA) estimates that roughly 90% of existing U.S. homes are under-insulated. That means that the occupants are less comfortable, and both energy and money are being wasted.
It's called the touch test. Go around your home and touch the walls. If you notice that the walls are much colder to the touch than the ambient temperature of the room, or if they feel damp, you have good reason to suspect insulation problems.
You don't have an obligation to insulate the walls in an older home, nor do you have to disclose the lack of insulation in most states. Most buyers of older homes are aware of the various charms and pitfalls of owning this type of property. However, that doesn't mean that adding insulation has no value.
A lack of exterior wall insulation can lead to cold drafts coming through electrical outlets and light switches. These cold drafts contribute to high energy bills, as the furnace is constantly running. Filling the external wall cavity with insulation will help reduce the drafts depending on the material used.
Without adequate wall insulation, you could be losing as much as 25% of your home's heat in winter and gaining up to 25% more heat in summer. If your home is uncomfortably cold in winter, unbearably hot in summer and difficult to heat up or cool down, chances are you need to replace your wall insulation.
It's not that uncommon to find that these beautiful old houses don't have any insulation in the walls at all. Or if there is insulation in the exterior walls it has shifted, settled, and sagged over time. Whether you want your older house to be more comfortable or energy-efficient, RetroFoam insulation can help.
Heating and cooling systems work hard to keep the home at the desired temperature. When a home has inadequate insulation in the attic, a lot of air is lost through the roof. Energy bills skyrocket, and it's impossible to keep the temperature in the house regulated.
Mold Control: Eliminating Sources of Moisture
Homeowners can utilize an assortment of measures to control and eliminate this issue. Yet, insulation is an integral first line of defense. A lack of insulation in your house can cause mold because you have no moisture management strategy against the outside.
You can check insulation in walls by removing an outlet cover or light switch to take a quick peek inside the wall to determine if there is any existing insulation in there. Another option is to drill a hole somewhere inconspicuous, like in the closet or under the baseboard, to take a look.
Lacking proper insulation in a home can lead to many uncomfortable living conditions, significantly impacting the quality of life for its inhabitants. In the winter, the absence of insulation means that warmth inside the house escapes, leading to cold and draughty interiors.
Insulate all exterior walls, including (3A) walls between living spaces and unheated garages, shed roofs, or storage areas; (3B) foundation walls above ground level; (3C) foundation walls in heated basements.
Unless your home was specially constructed for energy efficiency, you can probably reduce your energy bills by adding more insulation. Many older homes have less insulation than homes built today, but even adding insulation to a newer home can pay for itself within a few years.
Deferred Maintenance. The last thing a buyer wants to see when walking into a potential home is a leaky faucet or peeling paint. While a seller might want to put their old home in their rearview mirror, minor repairs and updates might be necessary to close a sale.
State and local building codes typically include minimum insulation requirements, but your energy-efficient home will likely exceed those mandates. To optimize energy efficiency, you should also consider the interaction between the insulation and other building components.
Check Behind a Baseboard
But it's also important to think of what lies behind the baseboard. Baseboards cover up a gap at the bottom of your drywall. Since they're just nailed in place, you can check to see if there's insulation in the walls by prying a nail out and looking for foam or wool.
A: Yes, you can potentially sue your landlord for the issues you've described. In California, landlords are required to provide habitable living conditions, which include proper insulation, heating, and sealed windows.
In most cases, interior walls are not insulated during construction. Unlike exterior walls, which must meet local and state codes for insulation, interior wall insulation is rarely required. This is because interior insulation has much less impact on your home's energy efficiency – but it can still play a role.
