(Practice)Standard Practice for Installation of Mineral Fiber Batt and Blanket Thermal Insulation for Light Frame Construction
Standard Practice for Installation of Mineral Fiber Batt and Blanket Thermal Insulation for Light Frame Construction
SIGNIFICANCE AND USE
This practice recognizes that effectiveness, safety, and durability of insulation depend not only on the quality of the insulating materials but also on their proper installation.
This practice provides general procedures that will help to ensure installation of insulation in a safe and effective manner. It shall be noted that actual conditions in existing buildings vary greatly and in some cases additional care shall be taken to ensure effective and safe installation.
SCOPE
1.1 This practice covers procedures for the installation of mineral fiber batt and blanket thermal insulation in ceilings, attics, floors, and walls of new or existing housing and other light frame construction.
1.2 This practice covers the installation process from pre-installation inspection through post-installation inspection. It does not cover the production of the insulation materials.
1.3 This practice is not intended to replace manufacturers' installation instructions, but it shall be used in conjunction with such instructions. This practice is not intended to supersede local, state, or federal codes.
1.4 This practice assumes that the installer possesses a working knowledge of applicable codes and regulations, safety practices, tools, equipment, and methods necessary for the installation of thermal insulation materials. It also assumes that the installer understands the fundamentals of construction that affect the installation of insulation.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4. Significance and Use
4.1 This practice recognizes that effectiveness, safety, and durability of insulation depend not only on the quality of the
insulating materials but also on their proper installation.
4.2 This practice provides general procedures that will help to ensure installation of insulation in a safe and effective manner.
It shall be noted that actual conditions in existing buildings vary greatly and in some cases additional care shall be taken to ensure
effective and safe installation.
5. Safety Precautions
5.1 The installer shall wear proper clothing and equipment as recommended by the insulation manufacturer.
5.2 Inareaswhereinsulationistobeinstalled,componentsoftheelectricalsystemshallbeingoodcondition.Ifthereisreason
to believe the electrical system is faulty, do not install insulation in such areas until the owner has been informed and repair has
been accomplished.
NOTE 1—The CPSC Product Safety Fact Sheet No. 18 has identified the following signs of electrical deficiencies: lights dimming, fuses blowing,
circuit breakers tripping frequently, electrical sparks and “glowing” from receptacles, light flickering, and coverplates on switches and outlets that are
warm or hot to the touch.
6. Pre-installation Inspection and Preparation
6.1 Inspect the roof, walls, ceilings, and attic floors to identify areas where previous or existing moisture problems have caused
paint peeling, warpage, staining, visible fungus growth, rotting, or other structural damage. Do not install insulation in such areas
until the owner has been informed and has certified that these conditions have been corrected and their source(s) of moisture
eliminated.
6.2 Provide proper attic ventilation in accordance with local building requirements or practices, such as the ICC International
Residential Code.
6.3 When the attic has soffit vents at the eaves, make provisions to prevent insulation from blocking the vents and restricting
attic ventilation.
6.4 Where insulation is to be installed beneath floors over crawl spaces or on crawl space walls, cover the ground surface with
a vapor retarder.
6.5 Provide proper crawl space ventilation in accordance with local building requirements or practices, such as the ICC
International Residential Code.
6.6 Inspect attic floors for openings that might permit entrance of air from conditioned spaces below. Do not install insulation
in such areas until the owner has been informed and has certified that these conditions have been corrected.
7. Installation Procedures
7.1 General:
7.1.1 Handle the insulation material in accordance with the manufacturer’s instructions and keep free of extraneous materials.
Keep materials dry, off the ground, and protected from water.
7.1.2 It is difficult to describe every situation that will be encountered by the insulation installer. In general, however, the
installer shouldshall be guided by the need to reduce heat flow around or through obstructions and to protect mechanical systems.
Wherever insulation is installed in a building, it is very important that it fit snugly on all sides. If the insulation is too long for a
space, cut it to the correct size. If it is too short, cut a piece to fill the void.
7.1.3 Installtheinsulationinsuchawaythatthethicknessspecifiedbythemanufacturerismetorexceeded.Avoidcompression
of the insulation where ever possible. Failure to achieve the manufacturer’s labeled thickness will reduce the R-value.
