Roll / Twin Roll / Rollbatt - Insulation

ROCKWOOL® Roll consists of a single 1200 mm width roll, Twin Roll is a single width roll pre-split into two 100 mm layers, enabling fast-fitting into and over the top of loft joists. Rollbatt is a single thickness roll pre-split into 400 mm or 600 mm widths. The rolls all provide excellent medium-density thermal, fire, and acoustic insulation.

Features and benefits:

• Lightweight, water repellent and rot proof stone wool insulation, suitable for installation between roof and floor ties/ joists in domestic, commercial and industrial buildings.
• Provides thermal, acoustic and fire resilient properties.
• Thermal, fire and acoustic properties in one product.
• Euroclass A1 non-combustible.
• Multi-application.
• Dense, durable and robust rolls reduce slumping and sagging.
• Lightweight and easy to cut and fit.
• U-value: 0.14 W/m²K (in a traditional loft application at 300 mm thickness).
• Rockwool rolls are CE, Key and Kitemarked in accordance with BS EN 13162:2012+A1:2015.

Acoustics:

The incorporation of ROCKWOOL Roll, TwinRoll and Rollbatt within suitably designed constructions provides improved levels of sound reduction.

Durability:

ROCKWOOL stone wool is highly resilient, durable and dimensionally stable, maintaining its thickness and shape over time. Moreover due to its fibre structure and overall flexibility, stone wool can easily fit into available spaces, helping in avoiding unplanned air gaps, cracks or other installation errors in the final construction, ensuring stable performance over time.

Water repellence:

ROCKWOOL Insulation products work with the fabric of the building, preventing water from penetrating, but allowing moisture vapour to pass through.
