The Seasons, They Are A-Changin’: Three Ways to Insulate Your Home

September 20th, 2010 | Posted by tjones in Air Quality | Environment | Green Building | Green Homes

Here in the Northeast, the first signs of autumn have arrived: brisk evenings, golden leaves on the trees, the smell of wood smoke.  As days grow shorter and the weather colder, we’ll be turning to our furnaces and stoves to keep us warm.  Of course, we should keep in mind that however we choose to heat our homes – with wood, oil, or gas – there will be an environmental impact.

The more we heat our homes, the more money we spend, the more resources we consume and the more greenhouse gases we emit into the atmosphere.  The EPA estimates that in the United States, approximately 4 metric tons of CO2 equivalent are emitted each year from residences – a major percentage of which is related to home heating.  Since most homes rely on furnaces and boilers that burn fossil fuels, it is essential to ensure that our homes are heated as efficiently as possible, saving the individual both energy and money.  Hence, the importance of insulation!

Using conventional insulation can only go so far in achieving environmental sustainability.  Conventional fiberglass insulation is a suspected carcinogen, and is typically produced using new materials, by melting down glass and spinning it into tiny fibers.  Those fibers are painful – touching fiberglass insulation leaves an itching, burning sensation as those fibers lodge themselves below the skin.  Fiberglass insulation dust becomes airborne during installation and can become embedded in the lungs.  Finally, the chemicals used to bind fiberglass batting together are often petroleum-based and are suspected to “off-gass” toxic phenol, formaldehyde, and VOCs (volatile organic compounds).

It’s fortunate that there are several green products available that can help keep homes well-insulated (indeed, better than conventional insulation), their inhabitants safe, and are more environmentally-sustainable in their use of recycled materials.  They are exceptional products – composed of recycled paper, cellulose fibers, and blue jeans.

Three of these green products are featured below:

1. Bonded Logic Ultratouch Recycled Cotton Insulation is constructed from recycled blue jean material – and is remarkably soft.  While touching fiberglass insulation can result in pain, cotton fiber insulation is soft enough to use as a pillow.  Bonded Logic insulation in particular is chemically-treated by anti-fungals and fire retardants that are EPA-registered and environmentally sound.  The R-Value (that is, a measurement of insulation efficiency.  The higher the R-value, the better the material retains heat) is notably higher than that of fiberglass insulation – 3.5”-thick fiberglass insulation has an R-Value of 10.9, while Ultratouch is rated at 13.

The product is also LEED-certified and can installed easily at home.  Green Depot is also able to quick ship Ultratouch Recycled Cotton Insulation in pallets to specific states.  For more information on where this product can be shipped as well as all technical specifications, please click here.

2. Knauff’s EcoBatt Glasswool is an comfortable option for homeowners wanting to insulate their homes with a more familiar – and significantly safer – fiberglass option.  While conventional fiberglass insulation has any number of problems – it is energy- and material-intensive in its production, it puts out significant amounts of dust during installation, and outgases formaldehyde – EcoBatt is far more kind of people and the environment.  Constructed out of a minimum 30% post-consumer recycled glass bottle content, EcoBatt as contains no formaldehyde and is low-dust.  Conventional fiberglass uses binding materials that are petroleum-based; EcoBatt, on the other hand, uses a binder that is made from renewable organic materials.  All told, EcoBatt’s production practices and materials are more mindful of the environment and the individual – up to 70% less energy-intensive than traditional binders.

EcoBatt is also a bit more versatile than Ultratouch – it comes in a number of widths, R-values, densities, and facings.  For technical specifications, you can either visit Green Depot here, or view the product brochure here.

3. National Fiber Cel-Pak Cellulose Insulation is a third option.  Cellulose insulation is notably different from familiar batten insulation — it is fill insulation, meaning that it is pumped in with vacuums into walls, attics, and ceilings.   Cellulose insulation is made from 100% recycled newspapers and treated with non-toxic borate fire retardant.  A substantial benefit of cellulose insulation is that it fills every nook and cranny.  Batten insulation, and especially fiberglass insulation, leaves large gaps between pipes and beams that can reduce insulating efficiency for the home, costing energy and money.
