Modern modular homes are typically insulated with strands of fiberglass batten strips. In the fall season, insulated sidewalls keep the warmth within the home and prevent icicles. Contrarily, the attic gets insulated with thick fiberglass batten strips during summer to keep the living temperatures down.
In fact, the fiberglass insulation has good R-Value and a price of its own exclusive to the modular home prices. Further, the U.S. Department of Energy has also asserted separate insulation cavity for modules attic, ceilings, sidewalls, and floor.
Fiberglass blankets come in separate sizes, so that dwellers could insulate all parts of the home, conserve energy spend on modules, and get savings on energy bills. The fiberglass batten strips fill the standard stud cavity and fill floor joists cavity with insulation. However, fiberglass batten strips cannot be used as an insulation material on water lines since fiberglass doesn’t hold water. So to weather-strip the belly wrap of modern modular homes, general contractors would drill holes through floor joists in the blow-in method.
The blow-in insulation method works perfectly if the contractors could access floor joists, and ideally, if the belly wrap is aligned crosswise. Blow-in insulation method fully fills fiberglass around the pipes and wires and seals the air gaps in the prefab’s underside. If the belly wrap were aligned lengthwise, contracted employees would drill multiple holes through the joist bay from beneath the prefab home foundation and fill the floor joists with fiberglass.
The fiberglass batten strips tend to have between 20 to 30 percent recycled glass content, and is considered as a “loose-fill” insulation material. The strips may tear off after considerable wear and tear and prolonged usage of the prefab home. The fiberglass blankets, however, are also blown-in to the sidewalls by certified general contractors.
Relevant studies have shown that sidewalls last for longer periods if fiberglass blankets are used on the sidewalls of a prefab home. Yet again, fiberglass blankets tend to cost high when compared to standard insulation materials and uses blowing equipment to weatherize the home exterior.
The fiberglass blankets with R23 cavity shall be used on 2 x 6 sidewalls to airtight the exterior and to prevent moisture. To know more about things that influence modular home prices in that way, contact a prefab dealer in your area.
