significant facts

Cellulose insulation outperforms other insulations in certain key areas for you the homeowner. The goal is clear:  unnaturally keep your home cool in the summer and warm in the winter ( opposing temperature of exterior climate ). Cellulose is the clear winner when all categories are considered.

Blow in Cellulose Insulation is covered by the American Society for Testing and Materials Standard Specifications (ASTM). The ASTM covers several material properties, including:

  • R-Value
  • Flame spread
  • Smoldering combustion
  • Density
  • Corrosiveness
  • Odor emission
  • Moisture vapor absorption
  • Fungi resistance
  • Adhesive/cohesive strength (spray on only)

Blown In Cellulose

Cellulose is superior to other insulation materials and benefits and cons must be considered separately on each home project. 

Good for your home
and environment!

Blown in cellulose insulation is produced primarily from post-consumer wood pulp (recycled newspapers), typically accounting for roughly 85 % of the insulation by weight. Cellulose insulation is treated with fire-retardant. Borates and boric acid are used most commonly and account for the other 15 % of the cellulose insulation by weight.

Mold Resistance

Cellulose significantly decreases the risk of mold even beginning to form. Thanks to its chemical treatment, mold doesn't grow on cellulose insulation. Cellulose insulation absorbs moisture, redistributes it and lets the attic/wall/ceiling dry in a controlled manner.

Pest Control

Cellulose insulation is pest-resistant insulation that is a great addition to your pest prevention plan. This insulation works on most common household pests such as cockroaches, ants, beetles, earwigs, silverfish, termites, etc.

Air / Vapor Barrier

Air infiltration is almost as important as R-value in the thermal performance of a building. Infiltration of unconditioned ambient air means that heating and cooling systems must expend more energy to compensate for the infiltration.

Sound Control

Cellulose provides very effective sound control to minimize outside noises and between rooms (if the interior walls are insulated). Many people only focus on the energy savings that can be achieved with blow in cellulose insulation but overlook the benefits that come from improved sound insulation. If you have ever walked into a house that is not insulated you will immediately notice that noises from outside of the house are “louder” than in an insulated home.

Fire Resistant

Besides saving you money, cellulose insulation also provides extremely effective fire protection capabilities. Tests conducted by Underwriters Laboratories Inc.® show that Cellulose insulation provides an effective 1 hour fire rating. This will slow the spread of a fire allowing you more time to escape any danger. This is because cellulose is specially treated using Borate Compound Chemicals as a fire retardant in the manufacturing process to meet or exceed all fire safety requirements.

Premium Plant Based

Cellulose insulation is one of the greenest products in the world. Green Attic Insulation Sources Its Cellulose From Wisconsin, USA learn more about Champion Cellulose @ Loose Fill Premium Class 1 Cellulose Insulation is the best choice for attic floors. It is blown in with high pressure truck mounted machines. This R-Value ( Resistance Value) protection against heat escape from the living space while providing superior heat protection in the hot summer by preventing heat to travel through the insulation to the living space ceilings.

Why Green Attic Uses Cellulose?

Blow-in Cellulose Insulation is installed in empty spaces in the structural framing to slow down the transmission of heat out in winter and reduce drafts/cold. Cellulose Insulation is used to control heat flow for the following reasons:
Cellulose Home Durability benefits:

Eliminates cold spots that may cause condensation problems resulting in the growth of mold and mildew and the staining of structural components as well as finish materials

Cellulose Comfort benefits:
Cellulose creates warmer surfaces and reduces chills and drafts caused by radiation and convection.

Prevents overheating due to excessive solar gains.
Cellulose Energy Efficiency Benefits:

Insulating with Cellulose = Results:  never before seen instant monthly energy savings which costs less as prices rise. Cellulose Insulation Creates Air Trapped Between Layers and divides the air space to reduce heat transfer in winter from the living side and heat intrusion from the attic side in summer. 

Here are considerable significant facts: cellulose insulation outperforms other insulations in certain key areas for you the homeowner. The goal is clear:  unnaturally keep your home cool in the summer and warm in the winter ( opposing temperature of exterior climate ). Cellulose is the clear winner when all categories are considered. 

Insulation Principles: 1. Heat moves from hot to cold Cellulose Prevents This Transfer 2. Air and water move from high pressure to low-pressure Cellulose Balances Room Temperature by Eliminating Cold Spots In Winter And Hot Spots On The Ceiling In Summer  3. Moisture migrates from wet to dry Cellulose Dense Packs The Framing Assembly / Stud Cavity eliminates drafts and moisture resulting from opposing temperatures.  

  1. Cellulose Manages Moisture
  2. Reduced BTU’s during manufacturing / Recycled Production
  3. Blocks Radiant Heat Transfer
  4. Quiet Home Through Sound Absorption  
  5. Cellulose Is The Highest Recycled Content Among Its Peers 
  6. Cellulose Disperses Moisture and increases building component longevity. 
  7. Eliminates Convective Air Movement 
  8. Plant Based Material 
  9. Higher Density = Better R-Value
  10. Cellulose Insulation Blown-in Method uses high pressure to completely fill gaps and voids around irregular objects such as conduit, pipes , framing etc. .

If you are looking for a company that couples outstanding work with outstanding customer service, then Green Attic Insulation is who you should definitely call. I truly wish I would have called them years ago as I have been putting off suspected issues that centered around extreme temperature fluctuations between winter and summer, along with poor ventilation, within my attic.

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.

Highly recommend! Green Attic is thorough, responsive, and professional. Although it has only been a month since we had the work done, the results are clear. Our house is more comfortable, while our gas consumption is down ~30% and electricity is down ~25%.
