Technowool Terrace Roof Board is a high-density stone wool insulation board designed to provide outstanding thermal insulation, acoustic performance, and fire protection for flat and terrace roof systems. When installed together with vapor barriers and waterproofing membranes, it forms a complete and highly efficient roofing insulation system.
Since flat roofs are continuously exposed to harsh weather conditions, they require durable insulation materials with long-term performance. Technowool Terrace Roof Board is specifically engineered to improve energy efficiency while enhancing fire safety in residential, commercial, and industrial buildings.
Technowool Terrace Roof Board is an unfaced, high-density stone wool insulation board developed for flat roof applications. Used in combination with waterproofing systems, it provides excellent thermal and sound insulation while offering superior fire resistance. Its robust structure makes it a reliable, long-lasting solution for modern roofing systems.
Designed to withstand roof loads, providing reliable performance in flat roof applications.
Reduces heat loss, improves energy efficiency, and minimizes external noise transmission.
Manufactured from A1 non-combustible stone wool, offering maximum fire protection without contributing to flame spread.
Its high-density composition maintains structural stability and insulation performance over many years.
Works efficiently alongside vapor barriers and waterproofing membranes to create a complete roofing insulation solution.
Technowool Terrace Roof Board is suitable for:
The insulation boards should be installed over the vapor barrier layer.
The boards may be installed in a single layer or in a staggered double-layer configuration to enhance thermal performance.
Secure the boards using mechanical fasteners appropriate for the specific roof construction system.
Complete the roofing system by installing a suitable waterproofing membrane over the insulation boards.
The board has water-repellent properties, but a waterproofing membrane must always be installed above the insulation to achieve complete waterproof protection.
It is manufactured from A1 non-combustible stone wool, providing outstanding fire resistance and contributing to building safety.
It can be installed on concrete, aerated concrete, and trapezoidal metal roof systems.
The board offers high compressive strength; however, suitability for frequent or heavy foot traffic should be evaluated according to the specific project requirements.
The insulation boards are placed over the vapor barrier, mechanically fixed with appropriate fasteners, and then covered with a waterproofing membrane to complete the roofing system.
