The Attic Insulation Ruler is a must-have tool for achieving accurate coverage and R-value compliance when installing blown-in insulation. Designed for professional insulation contractors, this ruler features large, easy-to-read measurement markings that clearly indicate installed depth from the attic floor.

These rulers help ensure your cellulose or fiberglass blown-in insulation meets specified R-values, prevents underfilling, and provides proof of correct installation for inspections. Simply staple the ruler to rafters or joists before blowing insulation, then use the depth markings to visually confirm consistent application across the entire attic.

Durable, lightweight, and easy to install, attic rulers are essential for residential and light commercial insulation work where accuracy and documentation matter.
