Fiber Glass Insulations for Residential and Commercial Envelope Applications

Fiber GlassA material consisting of glass fibers used in making various products, including yarns, fabrics, insulation, and structural objects or parts. Fiber glass is resistant to heat and fire. Insulations for ResidentialPertaining to a home or homes where people reside on a permanent basis. & CommercialA building classification - related to business as in commercial building. Envelope Applications:

 

Insulation reduces average heating and cooling costs by around 20 percent.

“Insulating Your Home: Save Energy and Money,” Better Homes and Gardens Home Information System, 1995.

Savings vary. Find out why in the seller's fact sheet on R-valuesMeasure of resistance to heat flow. Insulation materials have tiny pockets of trapped air. These pockets resist the transfer of heat through material. The ability of insulation to slow the transfer of heat is measured in R-values. The higher the R-value, the better the insulation material's ability to resist the flow of heat through it. The Federal Trade Commission prohibits expressing R-value in terms of inches, because R-value is not a linear measurement. R-values can be added togehter for a total system R-value.. Higher R-values mean greater insulating power.

 

There are several types of fiber glass insulation used for home and building envelopeThe exterior assembly that encloses the interior space of a building. It serves as the outer shell to protect the indoor environment as well as to facilitate its climate control. Building envelope design is an application area that draws from all areas of building engineering, especially building science and indoor climate control. Building envelope design includes four major performance objectives: Structural integrity; Moisture control; Temperature control; and control of air pressure boundaries (this includes air movement into and out of the interior space and through the components of the building envelope-interstitial). The physical components of the envelope include the foundation, roof, and walls, along with the insulation encompassed in these components, as well as the doors and windows. applications:

Fiber Glass Loose Fill (Blown In)

Fiber glass loose-fill (blown-in) insulation is available in two forms – either processed from a by-product of manufacturing battsPre-cut pieces of insulation in standard sizes; batts may have a facing of kraft paper, aluminum foil or poly (plastic) or no facing at all. or rolls, or from “prime” fibers produced especially for blowing applications. Both must be applied through pneumatic means using a mechanical blowing machine. There is no difference in the energy saving performance of the two as long as they are installed according to the manufacturer's instructions.

Fiber glass loose-fill insulationInsulation in granular, nodular, fibrous, powdery or similar form designed to be installed by pouring, blowing or hand placement. is designed for “open blow” applications such as attic spaces or closed cavityThe empty space between studs or joists typically filled with insulation. applications such as those found inside walls or covered attic floors.

Dense-Pack Wall Insulation

Loose-fill fiber glass insulation, specially designed for blowing or “dense-packing”, uninsulated or under-insulated walls is available from several manufacturers. These products have been tested to verify they resist air flow through wall cavities when installed according to the manufacturer’s recommendations and are labeled for this specific application. This type of installation usually requires cutting holes in either the exterior or interior side of the wall and inserting a hose to blow the insulation into the cavity at a minimum densityThe mass of a substance per unit of volume of a substance.. This type of installation should be done by individuals specifically trained for this type of work.

Fiber Glass Blanket InsulationA relatively flat and flexible insulation in coherent sheet form furnished in units of substantial area.

Fiber glass blanket insulation comes in either batt or roll form. The basic materials, sand and glass, are melted and then spun into wool-like fibers. These are processed into batt or roll insulation, with or without facingsDefinition One: A thin layer of laminate, usually factory applied, on the surface of an insulating material. Definition Two: A protective or decorative (or both) surface applied as the outermost layers of insulation..

Batts and rolls are designed for use in framing members of residential and other light-frame constructions. Standard widths are available for 16 and

24-inch on-center spacing; special widths (slightly wider) are available for steel studs so they fill the void in the steel studA vertical framing member (metal or wood) used in both exterior and interior walls.. A batt is a pre-cut piece of insulation, usually 47 to 96 inches in length. Rolls are available in lengths up to 70 feet.

Fiber Glass Metal Building Insulation

Fiber glass metal building insulation or NAIMANorth American Insulation Manufacturers Association, a trade organization representing manufacturers of fiber glass and rock and slag wool insulation products in North America. 202-96 Certified Metal Building Insulations are fiber glass blanket insulations that are manufactured to fit the widths and spacings of metal building girtsA girt is a horizontal structural member usually located on the wall in a framed wall - used as a term in metal building construction. and purlinsA purlin (or purline) is a horizontal structural member in a roof. Purlins support the loads from the roof deck or sheathing and are supported by the principal rafters and/or the building walls, steel beams.  Term used frequently in the construction of metal buildings..

These insulation blanketsInsulation which is typically wider than batts and is supplied in rolls. It may have facing of kraft paper or aluminum foil backed paper. are unique in that they are over-engineered meet the code requirementsThe criteria an applicant or project must meet in order to receive an incentive, or steps that must be taken in order to receive the incentive, such as having a home energy audit performed or using an approved contractor. specific to metal buildings and to maintain their R-value after the lamination, handling and installation process.

Latest Energy CodeLocal requirement that outlines the minimum level of insulation and other energy-efficiency measures for new construction. Energy Codes are updated on an ongoing basis, and minimum levels of insulation are set by considering the cost of energy and what level provides a reasonable payback. Requirements
