Sidewall Insulation

Insulation for the largest part of your Cleveland home, The Walls

Cleveland Home Insulation is proud to offer Sidewall Insulation to our Cleveland Ohio Neighbors

Exterior wall insulation is especially effective in homes built before the 1970s

  While the attic, basement, and crawlspaces are the most targeted areas for insulation, there is a fourth contender, and its the largest one of all, your walls.  Many of our callers tell us that they feel a draft or cold spot coming from a wall, or around an outlet, and especially around or under window frames.  Which is a clue to us, saying that you need sidewall insulation. 


  Drafty rooms and rooms with cold spots are an important detail, and when we do our inspections, a thermal camera is especially useful for uncovering the causes of the drafts.  Thermal cameras give several temperature measurements: they show room temperature as a whole, and the temperature where they are pointed using special lasers.   


  These cameras identify cold areas inside of walls and areas that need more insulation appear as cooler purples and blues instead of warmer yellow, orange and reds.  They allow us to come up with a plan of action to insulate and air seal your sidewalls.


If you have an older home, and notice that you feel drafts or cold spots while moving from room to room, its time to call Cleveland Home Insulation.  We will put a stop to air leaks, cold rooms, and provide your home with the best insulation at honest prices.  Call (216) 264-0848 to get your free quote and inspection booked

Insulation for the inside of your walls - or Sidewall Insulation as we say in the business


Sidewall insulation is fairly straight forward, its like filling up a cup, but the cup is your walls.  We make entry points, and fill them up full with densely packed insulation, then seal the entry points, in the most basic of terms.  But lets get a bit more in-depth!


First:  We will lay down drop cloths to make clean up a breeze, saving time and energy.  The other step for prep is to examine the structure of the home to determine how we will make entry points into the walls.  For brick structures we must make the entry points from the inside, through the drywall, rather than through the brick front of the home (you cannot patch up a brick like you can with drywall).  For homes with vinyl siding, wooden siding or panels, and other types of siding, we remove the panel or, when were able to, the entire course of siding (the whole strip of siding, in other words) to expose the wooden frame underneath. 


Second Step: Once the wooden frame under the siding is exposed, we drill holes 16 inches apart to make sure that we get access to every hollow space between the studs.  Then we insert our blower tube (like a big, reverse vacuum) and blow insulation into the walls.  We pressurize the vacuum to make sure that the insulation is densely packed into the walls, which give extra R-value over regular packing and does a much better job at getting the insulation into air gaps to seal them shut.  A thermal camera helps us guide the blowing hose to get into all areas of the wall cavity.  Many of our customers like to view the thermal camera as the stud wall cavities are filled, and we must say, its pretty neat to watch.


Third Step: We repeat the blowing insulation and dense packing every 16 inches until the entire lower layer of the house is complete, letting gravity assist us in the process.  Then we move up a couple of feet, remove the siding, drill more holes and gain access to other hollow stud cavities in the wall.  This is done all the way to the bottom of the attic (The attic requires its own, separate insulation, because attic's are constructed differently than walls).  As we complete one area and move to another, we will patch up the holes to keep all of the insulation in place, inside of the walls of the home. 


Fourth Step: Now we are able to replace all of the siding on the home that was removed and set aside.  As the final and last step: We clean up our drop cloth, laid down to catch all of our messes, from sawdust and escaped bits of insulation.  This keeps clean up swift and easy, saving you money in man hours.  All that is left to do is enjoy your home!

What insulation do we use inside of your existing walls?


Since pre-existing walls must be 'blown' with insulation, to avoid totally removing the drywall, there are two types that qualify, Fiberglass Loose-fill and Cellulose Loose-Fill. 



  • Cellulose is a big up and coming insulation, it is made from fiberized recycled paper, upwards of 80%, with one home full of cellulose insulation being equivalent to 40 years worth of recycled newspapers.  It does a fantastic job of insulating, and when densely packed into exterior walls, there is no setting over time.  Cellulose is the most Eco-friendly insulation type currently on the market.  Dense packed cellulose will give you an R-value of 4 per square inch.


  • Fiberglass is the reining world champion of insulation.  Since its invention in the 1930's, more and more homes have been insulated with fiberglass.  Made from super-heated glass fibers, fiberglass is good at trapping air between the fibers and will keep home temperatures stable for many years.  Fiberglass is an affordable option and performs just about as good as its cellulose counterpart with a dense packed R-value starting at 3.7

If you've noticed cold rooms and cold spots radiating from your walls, it may be time to have your insulation inspected and replaced.  Cleveland Home Insulation offers free inspections and free quotes for new sidewall insulation.  Give us a call today at (216) 264-0848 and schedule now!  Don't make do for another year!
