Blow-in Insulation Installation

Blow-in cellulose insulation seals thermal leaks far more efficiently than laid fiberglass.

BWR is a full-service heating and cooling company.

We don’t mean to belabor the point, but short of planting shade trees in the yard, we’ll do whatever it takes to properly regulate the temperature of your home or business and keep you in comfort.

This includes insulation — sealing your attic, walls (where accessible), windows, and doors for thermal leaks that drive up your energy costs and lead to drafts that can make some areas of your home feel like Greenland during the winter.

Thermal Leaks Lead to Higher Energy Bills

New homes and businesses in Southern California are usually well insulated. But this isn’t the case with many older buildings, unless the owner has made an effort at some point to reduce thermal leakage and upgrade the insulation.

As a full-service heating and cooling company, BWR installs blow-in insulation to seal attic leaks. And we do this for a very reasonable price, not much more than a DIY job where you might purchase insulation from a box store (are you sure you would choose the best kind?), rent a clunky machine, learn to operate that clunky machine on the fly, and crawl into your attic space, all the while praying that you don’t fall through.

Or you might hire a handyman, but are do you know if that handyman is competent and adequately insured? If anything happens to your hired help on the job, you the home or business owner could be liable. California.

Blow-in Cellulose Insulation vs Laid Fiberglass

R-value is “the capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power” (Oxford Dictionary).

The R-value of blown-in cellulose is 23% better per inch than fiberglass batts. Fiberglass loses up to 50% of its R-value in very cold conditions, and during the summer, fiberglass loses three times more R-value than cellulose when attics reach 110 degrees F.

Blow-in cellulose also offers a tighter seal. It plugs all nooks and crannies of an attic floor or wall space, as opposed to fiberglass batts placed between joists, which leave small spaces for air transfer.

Air leakage through gaps in insulation is responsible for approximately one-third of heat loss in a home. It also leads to discomfort regardless of temperature, as anyone who has felt an indoor draft during a January cold snap can attest.

Another problem with fiberglass is “wind washing,” which occurs when wind-driven air moves through your wall and attic insulation, depositing dirt and dust and lowering its R-value. Because cellulose insulation is denser than fiberglass, it’s more resistant to wind-washing, and it retains its insulating properties longer.

Cellulose Insulation Is Environmentally Friendly (Comparatively)

Cellulose insulation is made of 80% post-consumer recycled newsprint. Treated for fire resistance, of course! (That’s the good news in the newsprint.)

It’s also treated with borate minerals to discourage insects and rodents. And because it won’t rot, decay, or mildew, it doesn’t support fungus or mold growth.

The Cellulose Insulation Manufacturers Association claims that if all new homes were insulated with cellulose, this alone would remove 3.2 million tons of newsprint from US landfills every year.

Cellulose Insulation & Moisture

Wet insulation of any kind is never a good thing. But whenever cellulose encounters moisture, say, through the roof leak that was missed during your last inspection, it disperses that moisture rather than allowing it to pool. Thus, it can actually help to dry out wood beams, flooring, and other materials in contact with it and prevent mold growth.

Cellulose Insulation & Fire Safety

Counterintuitively, although it’s made of 80% recycled newsprint, cellulose insulation is a least as fire-safe as fiberglass and probably safer! Mineral treatment gives it permanent fire resistance, but the other important thing to consider is that fire needs oxygen to combust.

Cellulose fibers are densely packed, far more than fiberglass, and even without the mineral treatment, cellulose insulation would never burn especially well.

In any case, the cellulose insulation we install has been thoroughly tested under a variety of conditions and meets the standards of all city building codes in Southern California.

My AC went out on the hottest week of the year. BWR was at my house at 8PM and got the job done within the hour. The repair was very affordable and the team was very knowledgeable and professional. There were no sales gimmicks and no pressure tactics.

I would definitely recommend them to family and friends. Everyone if you need help with your AC or Heater please call BWR… Misty, Riverside.

Why You Should Hire BWR to Seal Thermal Leaks

BWR Heating & Cooling doesn’t hire contractors to do the hard or dirty work. Every job we do is performed by a professionally trained BWR technician with an average of 5 years of work experience in HVAC, heating, and air conditioning.

  • We’ll choose the right sort of insulation for your home or business.
  • We’ll perform the job much faster and with less inconvenience to you than a general contractor could.
  • We’ll do the job correctly and efficiently. Believe it or not, even blow-in attic insulation work can be performed badly!
  • We’ll check your home thoroughly for thermal leaks, and seal any additional leaks if you want us to.

As a result, you’ll save money on your heating and air conditioning bills. And you’ll be far more comfortable in a stable environment free of drafts.

Air Duct Sealing, Repair & Installation

Leaky or damaged air ducts can be a significant source of energy loss in your home, driving up energy bills, reducing the efficiency of your HVAC system, and forcing your air conditioner and furnace to work extra hard.

All air ducts deteriorate over time. 20 to 25 years is the maximum life you can expect, and even after 15 years, it’s time to consider replacing sections of your ductwork or even all of it.

Call us to inspect your ductwork.

  • Your air ducts may need a thorough cleaning — another service we provide.
  • But maybe there are leaks throughout your ductwork, which we can seal if the ducts are still in good condition.
  • Very old air ducts could be past the point of repair or cleaning. They should simply be replaced.
  • We can design new and improved ductwork for you, install it faster than you thought possible, and have your HVAC system running so efficiently that you’ll wonder why you didn’t call us sooner.

Why BWR & Not the Box Store, the Plumber, or the Fix-It Guy?

The contractor who installs your heating and cooling system is responsible for all warranties, including labor and materials.

Suppose you purchase a pricey HVAC appliance, only to discover that the seller has subcontracted installation to someone who arrives in an unmarked vehicle? Are you still confident the job will be done right?

Subcontractors are normally paid piece work. The faster they work, the more money they make. Shortcuts become a virtual certainty. Jobs are rushed.

Then there’s the question of liability and workman’s compensation. If something goes wrong and the subcontractor is underinsured, you the homeowner could be liable. So much for the 50 bucks you saved at Big Jim’s Cut-Rate Appliance last weekend.

All BWR team members have passed drug and background checks. They’ll show up on time in a marked BWR vehicle and wearing a BWR uniform. They’re trained to respect your property and your home, always removing debris when the job is complete.
