The replacement of ~R20 batt insulation
between the steel studs with ~R15 THERMAX[TM] ci Exterior Insulation on the outside of the steel studs increased thermal performance of the wall by 14%.
Now, primarily on the east and south walls, the batt insulation
became wet as a result of the storms, but in most cases, the vapor barrier prevented the wet insulation from coming into contact with the drywall.
Also, some fiberglass insulation batts are encapsulated to prevent workers from inhaling the fibers, and some manufacturers now use safer binders that replace the typical formaldehyde resin in fiberglass batt insulation
1 Stuff fiberglass batt insulation
into the space around the plumbing vent pipe as a backer for the expanding foam.
The RenewOVE employs the same framing methods as the MinOVE case and retains the use of exterior wood sheathing as in the conventional design, but substitutes cellulose insulation (produced from recycled newspaper) for the fiberglass batt insulation
in the wall cavity.
Rapidly renewable materials include bamboo and cork floors, wheatgrass cabinets, sunflower seed board, cotton batt insulation
and wool carpet.
It is easier to install, safer for the environment, and more energy-efficient than traditional batt insulation
, according to "Insulation Alternatives: Sprayed Foam Insulation," a report by ToolBase Services, a technical resource division of the NAHB Research Center in Upper Marlboro, Md.
Spray polyurethane foam insulation offers several advantages over traditional fiberglass batt insulation
steel, architectural wood casework, solid surface countertops, batt insulation
, metal roofing and metal siding, gutter & downspout, hollow metal doors & frames, doors, door hardware, aluminum storefront, aluminum windows, glazing, drywall, acoustical ceilings, resilient flooring, carpet, painting, signage, toilet accessories, toilet & shower compartments, lockers, fire extinguishers, plumbing, hvac, fire protection, and electrical and low voltage.
Current fiberglass batt insulation
provides R-values around 11 in the wall cavity of an exterior wall framed with 2x4 studs.
The correlation equation and the expressions developed in this paper provide a relatively simple way to calculate the U-factors for the single layer fiberglass batt insulation
assemblies without the necessity for doing detailed numerical simulation.
They started with copious amounts of super-efficient fiberglass batt insulation
from Johns Manville--R-38 in the ceiling and R-21 in the walls.
