Simpson Strong Tie IS16-R100 Insulation Support Wire 100 Pack

Product Description

The SIMPSON STRONG TIE IS16-R100 is a 16-inch insulation support wire designed to hold batt insulation firmly in place between floor joists and ceiling joists. Formed from 14-gauge wire with mitered ends that grip tightly against framing members, these supports prevent insulation from sagging and maintain the thermal barrier over time. Each package contains 100 supports, providing enough quantity for full-scale residential framing runs or renovation work. Licensed contractors and experienced DIYers working on insulation retrofits or new construction install these supports by friction-fitting them between joists at regular intervals.

The IS16-R100 is suited for residential and light commercial applications where batt or blanket insulation must be secured between joists in floors, ceilings, and crawl spaces. The 16-inch length targets standard 16-inch on-center joist spacing, the most common framing layout in residential construction. The 100-count pack reduces job-site restocking and is well-suited for contractors handling multi-room or multi-unit insulation scopes.

Key Features

• 14-gauge wire construction resists bending and holds insulation load without deforming
• Mitered ends grip joists to stay in position without fasteners
• 16-inch length sized for standard 16-inch on-center joist spacing
• 100-count pack supports large-scale or multi-room installations
• Reduces insulation sagging that leads to thermal loss and reduced energy efficiency

Compatibility

Designed as an OEM-style replacement and standard-fitment support for residential batt and blanket insulation installed between 16-inch on-center framing members in floors, ceilings, and crawl spaces.

Installation Notes

Insulation supports of this type are installed by building contractors, insulation specialists, or qualified DIYers as part of thermal envelope work governed by local energy codes and the International Energy Conservation Code (IECC). No fasteners are required; the mitered wire ends are compressed and released between framing members to create a friction hold. Ensure insulation batts are cut to proper width before installing supports at regular spacing intervals to prevent gaps. Do not overtension the wire during installation, as this can cause the ends to slip off the framing face.
