Rockwool Flexi Slab

Rockwool Flexi Slab

The Rockwool Flexi Slab is one of several revolutionary Rockwool sound insulation systems. For many years, Rockwool has manufactured insulating materials for homes, trades, fire protection, industrial insulation, and even marine and offshore insulation. You may trust that a Rockwool product will be produced to the highest possible quality level to provide excellent thermal efficiency.

What is Rockwool Flexi slab?

Rockwool flexi slab insulation is a slab-shaped multi-use insulation product made from renewable volcanic rock. Rockwool is extremely fire resistant due to its natural source of volcanic rock and its renewable features, reducing the carbon footprint of buildings considerably. Stone wool is also an excellent insulator since the tiny strands trap numerous air bubbles between them, preventing heat from passing through and keeping the structure warmer on cold days and colder on warm days.

The benefits of using Rockwool Flexi Slabs

Thermal, acoustic and fire resistant

Rockwool Flexi Slabs have excellent thermal, acoustic, and fire resistance properties, making them suitable for a wide range of applications. Furthermore, Rockwool Flexi Slabs are non-combustible to Euroclass grade A1.

Patented flexible edge

The Flexi slabs include a one-of-a-kind and patented flexible edge along one side of the insulation slab. This flexible edge ensures that adjacent insulating slabs have a firm friction fit with the supporting framework, reducing the likelihood of air gaps developing, which may lower the insulating effectiveness and allow air to flow through.

Semi-rigid structure

The insulation slabs in the Rockwool Flexi line have been designed to be semi-rigid, which means they will not slump down over time, even if the studs within which they are placed shrink. This significantly improves the product's longevity and ensures that the flexi slabs remain highly insulating over time.

Wide range available

Rockwool Flexi Slabs are available in a variety of thicknesses and widths to suit a variety of tasks, including acoustic and fire insulation for walls, separating walls and floors, and thermal insulation for suspended floors, walls, roofs, and more.
