Overview

ROCKWOOL Insulation is a versatile mineral wool product crafted for comprehensive building envelope protection. Its dense, fibrous matrix traps air pockets that provide effective insulation, significantly reducing heat transfer and energy consumption. Unlike fiberglass insulation, Rockwool is naturally fire-resistant without added chemicals, offering peace of mind in building safety and compliance with stringent fire codes.

This insulation performs exceptionally well in cold and humid climates due to its hydrophobic yet vapor-permeable nature, which prevents moisture accumulation inside wall cavities and ceilings. This unique balance supports healthier indoor air quality and protects building materials from mold and rot, extending the service life of the structure.

Builders and contractors value Rockwool for its easy installation — panels and batts cut cleanly and fit snugly into framing cavities. The product’s sound-absorbing qualities also make it a preferred solution for multi-family housing and commercial projects where acoustic separation is critical.

Compared to traditional foam and fiberglass insulation, ROCKWOOL offers superior long-term performance in thermal resistance, fire safety, and durability. Its sustainable manufacturing process uses recycled materials and is fully recyclable at the end of its lifecycle, aligning with green building certifications and environmental standards.

Guide

Installation

Step

01

Prepare the installation area by ensuring cavities are clean, dry, and free of debris or sharp objects that could damage the insulation.

Step

02

Cut ROCKWOOL batts or panels to fit snugly into wall, floor, or roof cavities using a sharp utility knife or insulation saw.

Step

03

Place insulation firmly without compression to maintain its insulating properties. Avoid gaps, voids, or overlapping for optimal performance.

Step

04

Install vapor barriers or air barriers as specified by project requirements to complement Rockwool’s moisture management properties.

COMPARATIVE TESTING

When measured against fiberglass, cellulose, and foam board insulation, ROCKWOOL consistently provides higher fire resistance ratings, superior sound absorption, and better moisture control. Independent lab tests show ROCKWOOL’s thermal conductivity remains stable over decades, whereas some foam products degrade with age and UV exposure. Its fire resistance helps projects meet or exceed building codes for passive fire protection, reducing risk and insurance costs.
