Fiberglass Installation – New Construction Processes

At Everlast Insulation, we take great care and precision to ensure each job is done right. For new construction projects, we typically install loosefill fiberglass insulation using the Blown-In-Blanket® System. It is a fast, efficient way to achieve excellent energy performance from the start. Mesh is easily installed over the exposed interior framing and injected with insulation prior to drywall installation. The following sections describe the process used for installing Blown-In-Blanket® fiberglass insulation in a new-construction application.


  • Seal around windows and doors with foam or batt insulation.
  • Mesh is applied by gluing or stapling to the wood or metal studs according to Blown-In-Blanket® specifications.
  • A nozzle is inserted behind the netting and blown fiberglass is blown throughout the cavity.
  • Work areas are cleaned.
  • Drywall can be hung immediately due to the insulation being dry, not wet unlike wet spray cellulose
    which requires at least 24 hours of drying time (or 25% moisture is reached).




  • 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.
  • Work areas are cleaned.
