  1. INSULATION CHRIS JACKSON & ALEXANDER GULIK

  2. LESSON OBJECTIVES • Able to correctly define what thermal insulation is without the use of reference material • Match the type of insulation with their properties with 100% accuracy. • Explain the use of insulation in current technology and predict the uses of the further. • To solve the math problems to an accuracy of 80%.

  3. DEFINITION • 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 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.

  4. Heat Flow • 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. • During the summer, heat moves from outdoors to the house interior. http://www.ornl.gov/sci/roofs+walls/insulation/ins_01.html http://change.ie/Global/General%20Content%20Images/insulation-heatloss.jpg

  5. INSULATION • 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. • Insulating ceilings, walls, and floors decreases the heating or cooling needed by providing an effective resistance to the flow of heat

  6. 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. • Materials with the same R-value have the same insulation performance no matter what materials are used.

  7. TYPES OF INSULATION • Batts • Rolls • Loose-fill • Rigid foam boards • Blanket • Reflective www.kyanite.com/newimages/insulation.jpg starbulletin.com/2001/05/19/features/artc.jpg www.rsarecycle.com/images/insulation.jpg www.hamiltonsupply.com/images/JM%20Roll%20Insulation.gif

  8. BATTS & ROLLS • 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. Framing members are 16” or 24” on center. Insulation is usually 15” 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. 3 ½ fiberglass = R 11 5 ½ fiberglass = R 19 • Protective equipment must be worn when installing. http://www.morrisblack.com/grafx/insulation2.jpg Click safety guy for equipment http://images.doityourself.com/stry/a/atticinsulationdojob.jpg

  9. LOOSE-FILL • 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. • 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. • Can only be professionally installed. http://www.marshallsinc.com/images/owens_c/oc_loose.jpg garsideinsulation.com
