If you're looking to insulate your home or business property, you will certainly want to cover the attic, basement/crawlspace, and ceilings. But without a doubt, a large proportion (probably a majority) of your building's insulation will likely be located inside of the walls.
And without walls insulation, heat will "leak" out of your home in the winter and raise your heating bill, and leak into your home in the summer and raise your AC expenses. Exterior walls must be air sealed and insulated to create an effective "envelope" to trap in the heat or the cool at the right time.
At Pure Eco, we can install new insulation in your walls, both for new construction or additions and for older construction, and we can do it without having to tear up your drywall or make a "big mess."
We have helped numerous home and business owners in the Los Angeles Area upgrade their energy efficiency levels, stay more comfortable all year long, and do their part to lower human impacts on our natural environment. Contact us today by calling 877-778-2551, and we can do the same for you!
Which Walls Do I Need to Insulate?
Any wall with an exterior face needs to be properly insulated to maximize your energy savings year-round. Even if your siding has built-in insulation attached to it, you need insulation inside your walls too if you want to reach optimal energy efficiency.
Additionally, if you want to heat or cool specific rooms instead of always the entire house, then you also need to install insulation inside of room-dividing walls that don't even have an exterior face.
Attic walls will normally get batts insulation, as will walls in unfinished basements/garages and in crawlspaces.
A wall between your living space and an unheated garage definitely needs some effective insulation in it.
Installation Methods for Walls Insulation
Both batts and blown in (loose fill) insulation is often used inside of wall cavities. Typically, batts is used on new construction while blown in insulation is more common with existing walls. But this can vary.
Blown In Insulation For Walls
Blown in insulation can be installed in your walls either from the inside of the house or from the exterior.
To blow insulation in from outside, we first lift up any siding that might be in the way, and then drill two-inch diameter holes between adjacent wall studs (about every 16 inches.) A hose is inserted into each hole and we fill in the inter-stud cavity compactly.
It's easy to plug up each hole before putting the siding panel, or other exterior wall covering, back in place. And you can use the cut-outs plus patching compound to ensure a solid plug-job.
To blow insulation into your walls from inside your house, the same basic procedure is followed, only holes must be made in the drywall. We do not take care of the patch and paint process ourselves, but we can recommend to you a top-tier professional who does. And all of the holes can be fully repaired with drywall tape and compound, plus appropriate sanding and painting.
Batts Insulation for Walls
You really can't put batts in old walls without tearing apart the drywall and completely redoing it. So, if it's a home renovation project where the walls are already opened up, an addition, or new construction, batts is a viable option. Otherwise, blown in insulation is the way to go (and you can, of course, blow insulation into new construction as well.)
Batts are sized by manufacturers to fit snugly between standard sized wall cavities (between studs). Thus, each batt need only be cut to length and pressed gently into position.
The paper backing of batts extends beyond the insulation around an inch, so that the pieces can be stapled to the studs and overlap with each other there, thus forming a complete wall envelope.
One should never compress batts insulation when installing it since that can make it lose much of its R-value. And also realize there are fiberglass batts with different R-values that are recommended for exterior walls, interior walls, attics, and basements.
Fiberglass is the most common form of batts installed in walls (and the least expensive type), but there are other alternatives like cellulose, cotton (recycled denim), mineral wool, and more, that may offer a higher R-value and have a greater percentage of recycled material in them.
When installing batts in walls, you must notch around electrical boxes and cut around pipes and cables. But you never press batts behind pipes since that would compress it.
Sometimes, it's best to also use spray foam to fill in small gaps inside the wall that might allow for air to pass through or for condensation to build up. Many batts have a paper backing that acts as a vapor barrier, but open faced batts are also sometimes used.
And for exterior facing walls, a vapor retardant poly film may be installed over the batts and stapled to the studs to keep it in place - this will help maximize energy efficiency with the walls that could potentially be the coldest otherwise.
Which Type of Insulation Should I Put in My Walls?
At Pure Eco, we deal primarily in three different types of insulation: fiberglass, cellulose, and Roxul Soundproof.
Fiberglass is the most affordable type of walls insulation, and it will give you enough insulating power for most situations. The fibrous material creates many air pockets that make for a high R-value, while the tiny glass shards scattered throughout give the material greater strength and durability. Fiberglass is also fire resistant.
However, fiberglass can be very itchy and needs to be handled with gloves, full protective clothing, and a face mask. It should not be left open face in a room you frequently use.
Cellulose is manufactured from recycled paper and cardboard, making it very eco-friendly. It packs tight, allowing little oxygen within the material, and it is treated to make it fire, mildew, and insect resistant. Cellulose costs a little more than fiberglass, but it also lacks the "itchy" quality of fiberglass.
If you want to not only heavily insulate a room but also soundproof it, Roxul Soundproofing Insulation is an excellent insulation to have installed in your walls. You can dampen sound a little bit even with batts, by caulking between top plates and along the bottom plate, but that is limited in its effects.
Roxul is made out of volcanic basalt rock and recycled metal slag. The resultant material is resistant to virtually everything, and its R-value is huge. This is also a very eco-friendly product that uses natural and recycled materials. But the main purpose for getting Roxul is that it is today's top-of-market sound barrier insulation product.
How Much Money Can I Save With New Insulation in My Walls?
Given the diversity of energy usage, building sizes and shapes, types and amounts of insulation used in walls and elsewhere, and other factors, there's no way to give a single one size fits all answer to the question of how much you would save by putting insulation in your walls.
But suffice it to say that uninsulated walls are constantly leaking energy and driving up your heating and cooling bills dramatically every single month.
Lack of proper or sufficient insulation, along with air leakage and inefficient HVAC systems, is a major cause of energy loss and high electric and gas bills.
Consider that the average US household spends over $150 a month on utilities. Heating and cooling account for almost 55% of the average electric bill. If you reduced your home heating/cooling costs by, say, 30%, even that could save you hundreds of dollars per year, every year for decades on end.
Around 35% of heat loss from buildings occurs when heat leaks out through the walls. It's true that heat rises and that it naturally would exit through the attic (25% of heat loss does occur there), but many more people have their attics well insulated than their walls, which helps account for these statistics.
The bottom line is, you are losing hundreds of dollars every year needlessly if your home has uninsulated walls.
And uninsulated walls also increase the demands placed on power plants that burn fossil fuels and increase our collective impact on the environment.
The Importance of Air Sealing
At Pure Eco, we offer full insulation services, including of course insulation of walls. But we also offer a number of important "accompanying" services, chief among them being that of air sealing.
If you have drafts in your home, be it in the walls, attic, ceilings, or wherever; that is going to counteract the effect of your insulation to a degree, lowering its R-value.
Especially before insulating attic walls, it's important to inspect for air leaks and seal them. We at Pure Eco can provide this service for you at the same time we install the insulation itself.
Deciding on How to Insulate Your Walls
Once you've made the decision to have your walls insulated, the next step is to decide which kind of insulation to use and whether it will be blown in or batts. And if blown in, you have to further decide on if you want it blown in from the inside or outside of the wall.
If you don't want to damage your drywall (although, again, the holes can be fully repaired), you might want insulation blown in from the outside. But if you have stucco instead of easily removable and re-position-able vinyl, wood, or aluminum siding, you might rather blown your insulation in from the inside.
And the choice between batts and blown insulation is very real when you are talking about newly built construction or a wall opened up for a home renovation project.
There are many factors that go into deciding these matters, as well as into deciding on an insulation type that delivers enough R-value, is environmentally friendly, and still fits your budget.
We at Pure Eco are experts in all of these matters. We have a lot of experience in helping home and business owners understand and weigh all of these competing factors so as to make an informed decision on their walls insulation that they'll benefit from for many years to come.
