Attic Insulation

making your home a comfortable place

According to energy.gov

Having a well-insulated attic and house is a great way to not only stay comfortable throughout the year, but also save a substantial amount of money over the lifespan of owning the home. The average homeowner can expect to save 30% on heating during the winter. The U.S. Energy Information Administration estimates that, on average, a homeowner can expect to save over $170 on natural gas and over $500 on heating oil to stay warm during the winter months. With the National Association of Realtors estimating that the median length of time that a family lives in a home to be about 9 years, that’s a lot of savings by having a properly insulated home and attic! 

One of the most cost-efficient and cost-effective ways of keeping your house comfortable year-round is to install insulation in your attic.

Heat Movement

Heat can transfer in and out of your house through three different methods: convection, conduction, and radiation. Convection is the most powerful and common way in which the inside currents launch the heat out of gaps in your home. When your walls have leaks and openings in them, the cold air will rush in to replace the warm air. 

Air Flow

These drastically different temperatures meet each other in walls, roofs, and insulation, located at the exact place where temperature and humidity contacts the new air outside of your home. This is known as a “weatherization problem” if your walls and roofs, etc. are not able to handle this transfer and meeting point point.

Difference Between insulation and barriers

Air Barriers:

Air barriers are systems of materials designed and constructed to control airflow between a conditioned (indoor) space and an unconditioned (outdoor) space.

Air barriers can be mechanically fastened building wraps, adhesive membranes, fluid-applied materials, insulating board stock, non-insulating board stock, spray polyurethane foam, poured concrete, metal, glass, and a host of other materials.

Traits of a good Air Barrier:

  • impermeable to air flow;
  • continuous over the entire building enclosure or continuous over the enclosure of any given unit;
  • able to withstand the forces that may act on them during and after construction;
  • durable over the expected lifetime of the building.

Vapor Barriers

Vapor barriers are materials used to slow or reduce the movement of water vapor through a material. Vapor barrier materials are installed on the warm side of the insulation in a building assembly, as determined by climatic conditions. In warm climates, it will be on the exterior and in cold climates, it will be on the interior.

A vapor barrier can be a mechanically fastened sheet-material, adhesive membranes (depending on composition), fluid-applied materials, insulating board stock or medium density spray polyurethane foam. The thickness of the material will impact whether it is a vapor barrier or not.

Does This Really Matter?

Yes! Air pressure and moisture control in buildings have become a very important element in constructing durable and energy-efficient structures.

Air leaks can cause havoc because air not only short circuits insulation, but air is a “carrier” for unwanted elements inside a home (i.e. noise, dust, vapor and heat/cold). When there is uncontrolled air movement from outside to inside (and visa versa), there is an increased risk for building failure or lackluster performance.  Moisture in all three states (vapor, liquid, solid) is a hazard to a building.

Here are 4  tangible benefits to air barriers:

1. Preventing the Loss of Conditioned Air

2. Lower Utility Bills

3. Preventing Moisture

4. Improved Indoor Air Quality

What Kind Of Attic Do You Have?

Insulation

Cathedral Ceiling Insulation

It can happen… well-built vaulted ceilings, complete with vents and fiberglass insulation, have moisture problems. The drywall becomes stained, the insulation becomes damp and the roof wood can even begin to rot.

Our crew is no stranger to this and depending on the situation foam insulation can be a solution to this problem.

Insulation

Conventional Ceiling Insulation

Dropped (or suspended) ceilings are among the simplest and most affordable ways to cover ceiling defects, wiring and overheard ducting. Lowering high ceilings also reduces heating and cooling costs. Dropped ceiling grids are typically 2-foot-by-2-foot or 2-foot-by-4-foot, so they accommodate standard 24-inch fiberglass insulation batts. For the best results, use batts that have paper facing on one side. The paper offers limited vapor barrier benefits and faces downward during installation.

"Recently did my home. Tim and the Addison crew came out and did my attic properly as it should’ve been done the first time. Explained every single question (i had a lot) i had before and during the job. Tim made sure during the job they were doing the air sealing properly because that’s what makes the biggest difference in keeping the cool/heat in the house and so that it doesn’t get lost in translation somewhere in in the attic. Highly recommend and speak with Tim when doing work in your property!"

James is prompt, thorough, and personable -- responded to my website inquiry right away and made it easy to schedule an appointment (still haven't heard back from the competition -- that was three days ago). He provided a detailed and professional quote within minutes of being on site and saved me from spending $20k on an unnecessary new roof! I'm glad I contacted Green Attic.

Tim and his crew then came out to remove the old insulation, clear/kill all the mold in the attic, remedy issues that were causing the mold in the first place (insufficient ventilation and blocked soffits), and finally re-insulate our attic/basement. The work was intense, but Tim's transparency with the process and willingness to educate us on the problems that we were having were what sold us. We also appreciated that Tim was able to work in some added value into his services without charging us the difference.

Related Topics To Attic Insulation

Insulation is material used that reduces heat loss or heat gain by providing a barrier between the inside of your home and the significantly different temperature outside.

It can cost between $1.50 and $3.50 per foot to insulate an attic depending on what insulation material you choose. 

The right insulation to use directly relates to the specification to the job at hand. Talk with our specialist and schedule a free inspection to determine the right course of action for your home.
