Attic Insulation

The 1st place to invest - But how much is enough?

The code for attic insulation in the State of Illinois is a minimum of R49 value.

What is R-value?

R-value is a unit of measurement of resistance to heat flow. The higher the R-value the more heat you retain in the winter and the more heat you keep out in the summer.

How can I tell if I have enough R-value insulation?

R49 translates into 16 1/4" of blown in fiberglass insulation.

Won't that much insulation block my eave vents?

It can if not properly dealt with. Eave venting is critical to your homes well being. Lack of eave venting can cause ice dams, roof deterioration, insulation degradation, roof deck rot, and mold growth. That is why a professional in home estimate/evaluation is recommended.

What type of insulation do we recommend?

All Comfort Insulation recommends Owens Corning Pro Pink Fiberglass. It is clean, lightweight, noncombustible, non hydroscopic, and won't support mold or mildew. It has the texture of cotton & contains no chemical by-products. Additionally, Pro Pink Fiberglass is a certified GreenGuard material containing an average of 58% recycled glass content. Other products simply do not measure up.

BENEFIT LOOSE-FILL (BLOWN) BATT
FULL COVERAGE IN ALL AREAS TO ELIMINATE HEAT LEAKAGE YES!    

 PROVIDES FULL AND UNIFORM COVERAGE OF AREAS, INCLUDING THOSE DIFFICULT AREAS BETWEEN CROSS BRACING AND TRUSS BRACING.ALSO COVERS ENTIRE AREA OVER TRUSSES AND JOISTS, THEREBY FILLING GAPS TO ELIMINATE ANY POSSIBLE HEAT LEAKAGE.

NO!

DIFFICULT TO PROPERLY FILL AREAS BETWEEN CROSS BRACING AND TRUSS BRACING.BATTS WHICH ARE PRE-CUT TO STANDARD WIDTHS CAN LEAVE GAPS AND OPENINGS THAT ALLOW HEAT LEAKAGE.

OPTIMUM R-VALUE YES!

ALLOWS OPTIMUM R-VALUE TO BE INSTALLED.CAN ACHIEVE AN R-VALUE AS HIGH AS R49 OR R60 TO MEET ENERGY CODES FOR THIS AREA.

NO!

MAY REQUIRE CUSTOMER TO USE MORE OR SLIGHTLY LESS THAN OPTIMUM R-VALUE THAT JOB REQUIRES.THIS CAN COST THE CUSTOMER MORE MATERIAL THAN IS ECONOMICALLY DESIRABLE, OR IF AN UNDER-RATED BATT IS USED, IT CAN COST THE CUSTOMER ENERGY SAVING DOLLARS.

PREVENTS MOISTURE BUILD-UP YES!

DOES NOT PERMIT MOISTURE ACCUMULATION IN INSULATION.PERMITS USE OF VENT CHUTES TO MAINTAIN OPTIMUM EAVE VENTILATION.

NO!

IF BATTS WITH A VAPOR BARRIER ARE NOT PROPERLY INSTALLED, THE VAPOR BARRIER CAN CAUSE MOISTURE ACCUMULATION, WHICH CAN RESULT IN WATER DAMAGE.AT LOW SLOPE ROOFS, BATTS MUST BE COMPRESSED AT EAVES.

PROFESSIONAL INSTALLATION YES!

ALMOST ALWAYS INSTALLED PROFESSIONALLY DUE TO COST OF EQUIPMENT (BLOWERS,HOSES, ETC.)THE PRO KNOWS HOW AND WHERE TO INSULATE, AND HE HAS THE RIGHT MATERIALS AND TOOLS TO DO THE JOB.THE PRO KNOWS ALL THE SAFETY HAZARDS TO AVOID.

FURTHER, "PRO PINK" LOOSE FILL IS MANUFACTURED UNDER STRINGENT QUALITY CONTROL, WITH ITS COVERAGE AND DENSITY LABELED ON EVERY BAG.

NO!

MOST OFTEN INSTALLED BY DO-IT YOUR SELFERS WHO NOT ONLY LACK THE RIGHT EQUIPMENT, BUT USUALLY THE SKILL AND EXPERIENCE TO DO A COMPLETE AND PROPER INSTALLATION.ALSO, THE DO-IT YOUR SELFER IS OFTEN UNAWARE OF SAFETY HAZARDS IN THE ATTIC.

COST SAVINGS YES!

PREFERRED BY MOST CONTRACTORS FOR INSULATING ATTIC AREAS BECAUSE IT SAVES INSTALLATION TIME LABOR AND MATERIALS.SINCE MOST JOBS ARE COMPETITIVELY BID, THESE SAVINGS CAN BE PASSED ON TO THE CUSTOMER.

NO!

DIFFICULT TO INSTALL PROPERLY IN TIGHT ATTIC AREAS, TAKES LONGER, USES MORE MATERIALS, AND MORE LABOR.THE RESULT: ADDED COST RATHER THAN COST SAVINGS.

RETROFIT INSULATION YES!

CAN BE QUICKLY, CLEANLY, AND ACCURATELY INSTALLED IN EXISTING HOMES.CAN BE INSTALLED UNDER FLOORED AREAS MORE EFFICIENTLY.

NO!

PROPER APPLICATION, WITH CORRECT STAPLING ON FLANGES, NOT ALWAYS POSSIBLE AFTER COMPLETION OF DWELLING.MOREOVER, SOME ACCESSES TO ATTICS ARE NOT LARGE ENOUGH TO ACCOMMODATE THE STANDARD BATT PACKAGING.TO INSULATE FLOORED AREAS, FLOORING MUST BE REMOVED & REINSTALLED COMPLETELY.
