What Is UKS Bautherm Rock Wool? A Fire-Resistant Insulation Solution for Walls, Roofs, and Floors

UKS Bautherm Rock Wool, manufactured by UKS Yapı, is a high-performance insulation material that provides thermal, acoustic, and fire insulation in a single solution. Thanks to its A1 non-combustible fire classification, low thermal conductivity, and excellent sound absorption performance, it is widely used in both residential and commercial construction projects.

Modern buildings demand high energy efficiency, sustainability, and fire safety. Bautherm Rock Wool addresses all three requirements, improving both the safety and comfort of buildings.

What Is Rock Wool? What Makes Bautherm Rock Wool Different?

Rock wool is a mineral insulation material produced by melting volcanic rocks such as basalt and diabase at approximately 1,400°C, then spinning them into fine fibers.

Its fibrous structure provides:

  • Excellent thermal insulation
  • Outstanding fire resistance
  • Superior sound absorption

Bautherm Rock Wool is manufactured in accordance with TS EN 13162 standards. Its homogeneous fiber structure, balanced density, and precisely formed boards ensure easy installation and long-lasting performance.

Installation Guide

External Wall Installation

  1. Clean and prepare the substrate.
  2. Fix the rock wool boards using insulation adhesive.
  3. Reinforce the system with mechanical anchors.
  4. Apply reinforcing mesh and finish with the exterior coating system.

Partition Wall Installation

  1. Install the metal stud framework.
  2. Fit the rock wool boards tightly between the studs.
  3. Cover both sides with double-layer gypsum boards.
  4. Finish all joints using joint tape and filler.

Advantages

Superior Fire Protection

Its A1 non-combustible classification means it does not ignite, drip, or produce toxic smoke. It is an ideal solution for hospitals, schools, shopping centers, and other buildings where fire safety is critical.

High Energy Efficiency

Its low thermal conductivity significantly reduces heat loss, lowering heating and cooling costs while improving overall energy performance.

Excellent Acoustic Performance

The fibrous structure effectively absorbs sound waves, reduces echo, and creates quieter, more comfortable indoor environments.

Breathable Construction

High vapor permeability minimizes condensation, helping prevent mold and moisture-related issues within building assemblies.

Durable and Environmentally Friendly

Bautherm Rock Wool maintains its shape and insulation performance for many years, contains no harmful chemical additives, and is recyclable.

Frequently Asked Questions

What is the difference between EPS and Rock Wool?

EPS primarily provides thermal insulation, while rock wool offers thermal insulation, fire resistance, and acoustic insulation in one material.

Does rock wool absorb water?

Water-repellent additives help prevent surface water penetration, while the fibrous structure remains vapor permeable, allowing the building to breathe.

Which density should be selected?

For external wall applications, densities of 80–100 kg/m³ are commonly used. For floor systems and service shafts, densities of 120 kg/m³ or higher are generally recommended.

Is Bautherm Rock Wool certified?

Yes. Bautherm Rock Wool products are manufactured in compliance with TS EN 13162 and carry CE certification.
