Residential Home Insulation

A home insulated with fiber glass, rock wool, and slag wool insulation is one of the most cost-effective ways of saving energy and reducing heating and cooling bills. In fact, if your home is as little as 5 to 10 years old, you likely have one of the 46 million under-insulated homes in the U.S. according to the Harvard School of Public Health.1 Adding batt or blown-in insulation is easy, and it is one of the lowest cost options for improving the energy efficiency of your home. Fiber glass, rock wool, and slag wool insulation also:

  • Improves comfort
  • Provides a healthier environment
  • Provides added sound control
  • Helps lower energy bills
  • Provides a lifetime of energy saving

Things to consider when choosing an insulation product include:

  • Ease of application
  • Thermal performance
  • Value

However, you should also consider the overall lifetime performance of an insulation product as well as its related safety aspects prior to purchase and installation.

Cellulose Insulation or Fiberglass Insulation ?

Pros for using either cellulose or fiberglass insulation

Cellulose Insulation:

1. Made from recycled materials so it is eco-friendly and green.

2. No adverse health effects from cellulose have been identified to date.

3. Cellulose has a high resistance to air flow and fluctuations in temperature do not decrease the effectiveness of the insulation.

4. The chemicals used to make the cellulose fire retardant are safe for humans but does repel rodents, insects and mold.

5. Cellulose will settle better than fiberglass and therefore has a settled R-value of 3.0 per inch compared to the R-value of fiberglass at 2.1 to 2.7 per inch.

Fiberglass insulation:

1. Fiberglass does not support combustion and requires no other chemicals for fire retardation.

2. Fiberglass is not absorbent and will not hold water. If it does become moist, it will dry out and return to its original R-value.

3. Fiberglass insulation includes recycled glass materials and uses sand as its main material, which is a “rapidly renewable resource” as defined by the U.S. Environmental Protection Agency.

4. Fiberglass does not settle much over time thereby maintaining its R-value with age.

5. Fiberglass is a reliable, tested insulation material that provides energy saving benefits.

Cons for using either cellulose or fiberglass insulation

Cellulose Insulation:

1. Cellulose is made from recycled paper and naturally produced fabrics, which, even though they are treated with chemicals, are highly susceptible themselves to fire and combustion.

2. Even though manufacturers say this is a “green” product for using recycled paper, more trees will then be used to create other products for consumption because the insulation is not recyclable.

3. Cellulose will absorb and hold moisture thereby reducing its energy saving potential.

4. Cellulose tends to settle more than fiberglass, which can reduce its R-value over time.

Fiberglass insulation:

1. The glass used in fiberglass can become airborne during installation and can cause health issues when inhaled. Extreme caution must be taken when installing fiberglass insulation. Furthermore, if fiberglass insulation is disturbed after installation then airborne glass particles will be hazardous.

2. Although the glass itself will not burn and is not combustible (it will melt if the fire is hot enough), the materials used to incase the fiberglass will burn if exposed to fire.

3. Fiberglass insulation is susceptible to changes in temperature, which will reduce the R-value but as much as 50% at times. You have to install fiberglass batt insulation of the top of loose fill or blown insulation that increases the cost and time of installation.

Before You Hire an Insulation Contractor

Before you hire a contractor for any insulation work:

  • Check references: Ask the contractor for references, including other homeowners for whom he has done work.
  • Ask trusted sources for a reference: The Department of Energy has a listing of resources for finding certified contractors. You can also check with the local Better Business Bureau for a contractor, or ask your bank to get a report on the contractor’s credit rating. Remember that you want good quality materials and labor as well as price. When you talk to a contractor, talk of R‑values. Don’t forget that R‑values are determined by material type, thickness, and, in the case of loose-fill insulation, by installed weight per square foot (or density), not by thickness alone.
  • Ask questions about how the contractor’s installers are paid: Does the contractor pay them by the number of square feet they cover or by the hour? If he pays them by square footage, they might do a hasty job on your house just so they can get on to the next one.
  • Check if the contractor has appropriate insurance coverage: Does the contractor have insurance to protect his own men if they are injured? Are you covered if one of his men damages your house? Ask for proof of current insurance.
  • Check bag labels: When you talk to a contractor or his salesman, ask him to show you a sample of the bag label for his brand of insulation and ask him to explain it to you. If a contractor uses insulation packed in bags that aren’t labeled, don’t hire him. The quality of the material will be unknown. Always deal in R‑values, not inches. Every type of insulation has a different range of R‑value per inch, and the Federal Trade Commission does not allow insulation to be marked by its R‑value per inch, except in very limited cases. You want a guarantee of a specific R‑value.

Managing Contractors

After you have hired a contractor, there are a few things to do to manage him:

  • Make sure the contractor gives you a contract or receipt for the insulation installed. This is required by law.
  • Check that the proper amount of insulation is actually installed. Ask the contractor how many bags of loose-fill insulation were installed.
  • After the job is finished, inspect your home to make sure the insulation was installed correctly.

Each item is described in more detail below

Check that the Proper Amount of Insulation is ActuallyInstalled

Each bag of insulating material used by the contractor should be marked with an R‑value. For loose-fill, the bags will tell you the R‑value for the area to be covered. It is important that you check that the proper amount is installed in your home. Ask the contractor to attach vertical rulers to the joists prior to a loose-fill installation in your attic to help you see that the proper depth was installed. Look for the R‑value printed on the batts, rolls or the facing.

Inspect the Insulation Work

Inspect your home to make sure the insulation was installed correctly. Demand quality from your installer and question anything that looks wrong. If this is new construction, ask if you or a professional can inspect the insulation before the drywall is put up. Some builder sand contractors do not want to do this, but after the drywall is up,it’s hard to tell if any mistakes were made, and much more expensive to fix. Don’t compromise. It’s your house, and you are the one that will have to live with any mistakes?

Air Sealing Milwaukee

Air Sealing

Air leakage, or infiltration, occurs when outside air enters a house uncontrollably through cracks and openings. Properly air sealing such cracks and openings in your home can significantly reduce heating and cooling costs, improve building durability, and create a healthier indoor environment.

It is unwise to rely on air leakage for ventilation because it can’t be controlled. During cold or windy weather, too much air may enter the house. When it’s warmer and less windy, not enough air may enter. Air infiltration also can contribute to problems with moisture control. Moldy and dusty air can enter a leaky house through such areas as attics or foundations. This air in the house could cause health problems.

The recommended strategy in both new and old homes is to reduce air leakage as much as possible and to provide controlled ventilation as needed.

Insulation Milwaukee? Do more with Weatherization!

Weatherization procedures

Typical weatherization procedures include:

  • Sealing bypasses (cracks, gaps, holes), especially around doors, windows, pipes and wiring that penetrate the ceiling and floor, and other areas with high potential for heat loss, using caulk, foam sealant, weather-stripping, window film, door sweeps, electrical receptacle gaskets, and so on to reduce infiltration.
  • Sealing recessed lighting fixtures(‘can lights’ or ‘high-hats’), which leak large amounts of air into unconditioned attic space.
  • Sealing air ducts, which can account for 20% of heat loss, using fiber-reinforced mastic(not duck/duct tape, which is not suitable for this purpose)
  • Installing/replacing dampers in exhaust ducts, to prevent outside air from entering the house when the exhaust fan or clothes dryer is not in use.
  • Protecting pipes from corrosion and freezing.
  • Installing footing drains, foundation waterproofing membranes, interior perimeter drains, sump pump, gutters, downspout extensions, downward-sloping grading, French drains, swales, and other techniques to protect a building from both surface water and ground water.
  • Providing proper ventilation to unconditioned spaces to protect a building from the effects of condensation. See Ventilation issues in houses
  • Installing roofing, building wrap, siding, flashing, skylights or solar tubes and making sure they are in good condition on an existing building.
  • Installing insulation in walls, floors, and ceilings, around ducts and pipes, around water heaters, and near the foundation and sill.
  • Installing storm doors and storm windows.
  • Replacing old drafty doors with tightly sealing, foam-core doors.
  • Replacing older windows with low-energy, double-glazed windows.

The phrase “whole-house weatherization” extends the traditional definition of weatherization to include installation of modern, energy-saving heating and cooling equipment, or repair of old, inefficient equipment (furnaces, boilers, water heaters, programmable thermostats, air conditioners, and so on). The “Whole-House” approach also looks at how the house performs as a system.

When to insulate?

No matter what kind of insulation you currently have in your attic, one quick way to determine if you need more is to look across the span of your attic. If your insulation is just level with or below your floor joists (i.e., you can easily see your joists), you should add more. If you cannot see any of the floor joists because the insulation is well above them, you probably have enough and adding more may not be cost-effective. It is important that the insulation be evenly distributed with no low spots; sometimes there is enough insulation in the middle of the attic and very little along the eaves. If your attic insulation covers your joists and is distributed evenly, you probably have enough.
