Blown-In Insulation

Blown In Blanket System (BIBS)

The Blown In Blanket System (BIBS) is a high performance fiberglass insulation solution for walls, ceilings, and floors. Unlike traditional fiberglass, which comes in pre cut batts, BIBS uses a proprietary fabric netting that is stapled to the framing. Specially manufactured loose fill fiberglass is then blown behind the netting at high density to fill every void and cavity.

Structo Insulation is a certified installer of BIBS, offering a custom fit insulation solution that maximizes thermal performance and minimizes air leakage.

What Is the Blown In Blanket System

BIBS creates a seamless thermal blanket within the wall cavity. The system relies on:

• Fabric retention
  A strong, breathable netting that holds the insulation in place.
• High density fill
  Insulation is blown in tight, preventing settling and ensuring complete coverage.
• Custom fit
  The insulation conforms perfectly around pipes, electrical boxes, wires, and odd shaped framing, eliminating the gaps common with standard batts.

Key Benefits of BIBS

Superior R value
Because of its high density, BIBS achieves a higher R value per inch than standard fiberglass batts.

Reduced air infiltration
The dense pack method significantly reduces air movement within the wall cavity, improving overall energy efficiency.

Complete cavity fill
BIBS eliminates "voids" and "compression" issues often found in batt installations, ensuring the insulation performs as rated.

Sound control
The dense fiber structure provides excellent sound dampening, making homes quieter.

Where BIBS Is Installed

BIBS is versatile and can be used in:

• New construction exterior walls (2x4 and 2x6 framing)
• Cathedral ceilings and challenging rooflines
• Floor systems
• Interior walls for sound control

Why Professional Installation Matters

BIBS is a specialized system that requires trained installers and specific equipment. Proper density is critical to performance; if the material is not packed tightly enough, it can settle. If packed too tightly without proper technique, it can bulge drywall.

Structo Insulation technicians are trained to install BIBS to manufacturer specifications, ensuring a smooth, flat surface for drywall installation and long term thermal reliability.
