DEFINITION Insulation Insulation Insulation is a substance that resists the transfer of heat, generally by incorporating small pockets of air. It does not stop heat transfer, simply slows the rate of transfer. Insulation is a substance that resists the transfer of heat, generally by incorporating small pockets of air. It does not stop heat transfer, simply slows the rate of transfer. Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness and density. Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness and density. Insulation is made from many types of materials. Fiberglass, rock wool, urethane foam, polystyrene, cellulose, glass wool, cotton or wood fibers. Insulation is made from many types of materials.

Heat Flow Heat flows naturally from a warmer to a cooler space. Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements - wherever there is a difference in temperature. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements - wherever there is a difference in temperature. During the summer, heat moves from outdoors to the house interior. During the summer, heat moves from outdoors to the house interior.

To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner.

R-VALUE The level or performance of an insulation product is measured by its Thermal Resistance or R – Value. The level or performance of an insulation product is measured by its Thermal Resistance or R – Value. The R-value is the measure of resistance to heat loss through a material. The greater the R-value, the more effective the insulation is. Preventing heat loss through winter and preventing heat flow through summer. The greater the R-value, the more effective the insulation is. Preventing heat loss through winter and preventing heat flow through summer. Materials with the same R-value have the same insulation performance no matter what materials are used. Materials with the same R-value have the same insulation performance no matter what materials are used.

BATTS & ROLLS Batts and rolls are either fiberglass or rock wool spun together to form a continuous piece of insulation. Batts and rolls are either fiberglass or rock wool spun together to form a continuous piece of insulation. Pre-cut pieces of insulation designed to fit in standard walls and ceiling cavities. Pre-cut pieces of insulation designed to fit in standard walls and ceiling cavities. Framing members are 16 ” or 24 ” Framing members are 16 ” or 24 ” on center. Insulation is usually 15 ” on center. Insulation is usually 15 ” or 23 ” wide and 3 ½ or 5 ½ thick. or 23 ” wide and 3 ½ or 5 ½ thick. Standard fiberglass insulation has a thermal resistance or R-values between R-2.9 and R-3.8 per inch of thickness.

LOOSE-FILL Loose-fill poured or pumped into a wall cavity or the roof space. Loose-fill poured or pumped into a wall cavity or the roof space. No cutting, fitting or stapling of the insulation, one of the fastest and easiest forms of insulation to install. No cutting, fitting or stapling of the insulation, one of the fastest and easiest forms of insulation to install. Loose fill materials include mineral wool and cellulose. Cellulose fiber is made from recycled paper which has been chemically treated to resist fire, rot and vermin. Loose fill materials include mineral wool and cellulose. Cellulose fiber is made from recycled paper which has been chemically treated to resist fire, rot and vermin. The advantage of loose fill insulation is that it is not restricted to standard sizes or shapes. The advantage of loose fill insulation is that it is not restricted to standard sizes or shapes.
