With rising demands for energy efficiency and comfort in modern architecture, interior wall insulation has become an essential part of both residential and commercial building projects.High-quality Stonewool Board Insulation not only significantly reduces indoor heat loss but also improves the wall’s fire resistance and sound insulation, creating a healthier and more efficient environment.

CCEWOOL® Stonewool Board is specifically developed for interior wall insulation. Made from natural Stonewool material, it features low thermal conductivity, high fire resistance, strong sound absorption, and moisture resistance. It is widely used in interior wall systems of residential buildings, apartments, office spaces, schools, and more—supporting the creation of energy-efficient and eco-friendly modern spaces.

Four Key Advantages of Stonewool Board Insulation

1. Long-lasting thermal insulation for stable indoor temperatures
The main goal of interior wall insulation is to minimize the exchange of hot and cold air between rooms and ensure stable indoor temperatures.
CCEWOOL® Stonewool Board features an extremely low thermal conductivity, effectively filling cavity spaces in wall structures and blocking heat transfer. Whether for keeping warm in winter or staying cool in summer, it helps maintain consistent room temperatures, reduces HVAC usage, and boosts energy efficiency.
2. Fire-resistant material tailored for interior walls
Walls without proper fireproofing can become “hidden pathways” for rapid fire spread during a fire emergency.
As a Class A non-combustible material, CCEWOOL® Stonewool Board maintains structural stability under high temperatures, forming a flame-resistant barrier that prevents fire from penetrating walls. It protects wall structures and electrical systems, making it a key material for interior wall fire safety.
3. Effective sound absorption for a quiet indoor experience
In residential and office environments, noise transmission between rooms can be a major concern.
By filling wall cavities with Stonewool insulation, CCEWOOL® Stonewool Board absorbs airborne noise and reduces sound reflection, significantly enhancing soundproofing. Whether for bedrooms, meeting rooms, or multi-family homes, it effectively minimizes noise interference and ensures privacy and peace.
4. Moisture-resistant and mold-proof for extended wall system lifespan
Moist air infiltration into interior walls can degrade insulation and lead to mold growth, compromising building health.
CCEWOOL® Stonewool Board is highly water-repellent and resists vapor penetration, while its breathability prevents moisture buildup inside walls. Ideal for high-humidity areas like kitchens, bathrooms, and basements, it helps extend the lifespan of interior insulation systems.
