Our cellulose insulation is so effective it can cut your energy bill significantly.
Spray cellulose insulation roof.
Open or closed cell spray foam is applied to the underside of the roof sheathing and additional fiberglass or cellulose insulation is blown in as a cost saving method for meeting high insulation requirements and filling in the cavity space between the rafters to the ceiling deck.
Amongst all of the popular types of insulation currently used by the industy spray foam insulation features the highest r value per inch.
Most low slope roof construction using spray foam use a hybrid approach where a combination of high density closed cell spray foam is used with fiberglass or cellulose insulation.
The r value of the impermeable layer depends on climate.
Cellulose is often the easiest choice to upgrade.
Typically fiberglass or cellulose are the material choices.
Control over noise where.
For example energy star recommends r 30 for a roof in the southern united states r 38 for the middle of the country and r 49 for the northern part of the country.
Spray foam insulation r values.
Comfort all year greenfiber keeps your home cooler in the summer and warmer in the winter.
Again the thickness or thermal resistance of the high density closed cell spray foam is specified by the international residential code irc based on climate zone.
Building insulation is low thermal conductivity material used to reduce building heat loss and gain and reduce noise transmission.
Benefits of cellulose insulation.
R25 is required for climate zone 6 in maine.
Cellulose has an r factor of at least 3 8 per inch moderately higher than fiberglass batts.
Often installed into wall cavities as a way to retro fit walls lacking insulation it can also be blown into unfinished attic spaces.
The word cellulose comes from the french word cellule for a living cell and glucose which is a sugar.
R value for loose fill per inch is between r2 and r4 higher value with.
Loose fill cellulose is relatively inexpensive yet still has an r value of about 3 5 per inch of thickness compared to fiberglass r value between r3 to r4 per inch.
This is one of the two most common types of insulation.
Cellulose insulation is plant fiber used in wall and roof cavities to insulate draught proof and reduce free noise.
Unvented roofs the code the 2009 irc section r806 4 makes explicit the requirement for impermeable insulation eg rigid foam board or closed cell spray above permeable insulation eg blown cellulose or fiberglass.
Because the loose particles blown in fill any and all odd shaped areas of the attic floor cellulose offers superior coverage without the need to custom fit pieces.
