Fiberglass Installation – Retrofit Processes

At Everlast Insulation, we take great care and precision to ensure each job is done right.
We trust Blown-In-Blanket fiberglass insulation when adding or replacing insulation in existing homes. The following describes processes we use for installing insulation in existing spaces.

EXTERIOR INSTALLATION FOR WALLS WITH SIDING (Vinyl or Aluminum):benefits

In cases where the house is sided, there will be no evidence of the holes; it will be under the siding.

  • Walls are first prepped for insulation by removing specific rows of siding (not all the siding is removed).
  • Holes are drilled to provide access to the wall cavities between studs.
  • Every cavity is then filled by pneumatically blowing the pure fiberglass into each and every wall cavity.
    Plum bobs and wires are used to determine where the studs and fire breaks are so that no cavity is missed.
  • Holes are plugged and siding is reinstalled.
  • Wood shavings and debris from the drills are swept up by brooms and/or shop vacs.

 

EXTERIOR INSTALLATION FOR WALLS WITH BRICK OR STONE:

  • For brick or stone, we can remove specific bricks from the exterior.
  • Holes are drilled to provide access to the wall cavities between studs.
  • Every cavity is then filled by pneumatically blowing the pure fiberglass into each and every wall cavity.
    Plum bobs and wires are used to determine where the studs and fire breaks are so that no cavity is missed.
  • Holes are plugged.
  • Wood shavings and debris from the drills are swept up by brooms and/or shop vacs.

 

INTERIOR INSTALLATION FOR WALLS:

In some cases, the most cost-effective way is to insulate is from the interior of the house. An Everlast Insulation representative
should meet with you to review your home’s exterior to determine the best method for installation.

  • Holes are drilled to provide access to the wall cavities between studs.
  • While the holes are being drilled, shop vacs are continuously run to collect debris during the drilling to minimize dust.
  • Every cavity is then filled by pneumatically blowing the pure fiberglass into each and every wall cavity.
    Plum bobs and wires are used to determine where the studs and fire breaks are so that no cavity is missed.
  • Holes are plugged with foam plugs, and two to four layers of plaster are applied and finished so that you do not see the holes.
  • Wood shavings and debris from the drills are swept up by brooms and/or shop vacs.

 

ATTIC INSULATION:

  • Attics are properly ventilated with baffles, where necessary.
  • Rulers are inserted throughout to monitor the correct level of insulation.
  • Insulation is blown throughout the attic to the R Value specified during the consultation.
  • Attic accesses are also insulated so that there are no voids in your ceiling.

Note: About 40% of the walls we insulate are from the interior, since other insulation companies are not trained or skilled to finish holes.
We pride ourselves in leaving a home the way we found it and can provide excellent references.
