Batt Insulation & Poly Vapour Barrier

Batt Insulation and Poly Vapour Barrier Installation

Performance installs batt insulation and poly vapour barrier for framed wall and ceiling assemblies, following the confirmed material, target R-value, and detailing requirements for the project.

How Batt Insulation and Poly Vapour Barrier Work Together

Batt insulation is fitted within framed wall and ceiling cavities according to the material, thickness, and target R-value specified for the project. Correct placement matters because gaps, compression, and incomplete coverage can reduce the intended performance of the assembly.

Poly vapour barrier is installed where required by the specified wall or ceiling assembly. Its placement and detailing around seams, corners, openings, penetrations, and transitions should follow the project plans and specifications.

How Batt and Poly Work Together

The insulation fills the framed cavities, while the poly forms the specified vapour-control layer within the assembly. Because the poly covers the insulated cavities, the batt placement and poly detailing need to be considered together before the wall or ceiling is closed.

Batt Insulation Installation

Batt insulation is fitted within the specified framed cavities according to the project requirements.

Poly Vapour Barrier Installation

Poly is installed where specified, with seams, openings, and transitions detailed according to the project documents.

One Coordinated Installation

Handling the confirmed batt and poly work together reduces handoffs between the two parts of the assembly.

What Batt and Poly Installation Needs to Address

The exact assembly comes from the project documents. These are the main parts of the installation that need to work together across the specified walls and ceilings.

Framed Wall Cavities

Batt insulation is fitted between framing members in the wall areas identified in the project documents.

Ceiling Assemblies

Batt and poly requirements for ceilings follow the assembly details and areas shown in the plans.

Specified Insulation Performance

The selected product, thickness, and target R-value are taken from the confirmed project requirements.

Poly Vapour Barrier

Poly is installed where required by the specified wall or ceiling assembly.

Seams and Transitions

Poly detailing at seams, corners, and transitions follows the applicable project documents.

Openings and Penetrations

Requirements around openings, electrical boxes, and service penetrations are reviewed against the specified assembly.

Send Us the Details. We’ll Review the Scope.

Provide the available project information, and our team will review the batt insulation and poly vapour barrier requirements and follow up about the next steps.

Helpful information to include:

  • Plans and assembly details
  • Approximate wall and ceiling areas
  • Specified product, thickness, or target R-value
  • Project location, access, and staging information
  • Target installation date and designated site contact

A Coordinated Installation Process

1

Review the Project Requirements

We review the specified areas, insulation material, target R-value, poly requirements, and relevant assembly details.

2

Confirm Site Readiness

Framing, services, openings, penetrations, access, and staging are confirmed before installation.

3

Install the Batt and Poly

The crew completes the confirmed batt insulation and poly vapour barrier work for the specified areas.

4

Complete the Handoff

Any outstanding items are communicated to the designated contact. Project-specific documentation or handoff requirements should be confirmed before work begins.

Coordinate the Surrounding Envelope and Interior Work

When your project includes additional insulation or interior work, Performance can discuss those requirements alongside the batt and poly scope.

Keeping related conversations connected can help clarify scope boundaries, sequencing, and which information is needed for each service.
