Internal Wall Insulation & Partition Systems
Internal wall insulation is utilized to increase the thermal resistance of exterior walls from the inside (when external facade insulation is restricted or impossible) and to deliver superior acoustic isolation between adjacent rooms.

Cement-Bonded Particle Boards (CPB)
Product Description
Cement-Bonded Particle Boards (CPB) are versatile, high-strength building materials that perfectly combine the structural solidity of cement with the flexibility of wood particles. Unlike wood-based sheets that rely on synthetic adhesives (such as OSB or chipboard), CPB boards are manufactured through eco-friendly compression without the use of toxic resins, phenols, or hazardous chemical additives. This process makes the material exceptionally durable, moisture-resistant, bio-stable, and entirely safe for indoor air quality and human health. The flat, dense surface provides an ideal substrate for various finishing options, including painting, plastering, or tiling.
Product Application
Engineered for multi-functional performance, cement-bonded particle boards (CPB) are heavily utilized across a wide spectrum of construction and retrofitting workflows:
- Framed Construction: Applied as a rigid material for both exterior sheathing and interior wall lining, providing a stable, heavy-duty, and fire-resistant structural core.
- Exterior & Interior Finishing: Used as a reliable, moisture-resistant substrate for modern facade systems, partition walls, suspended ceilings, and protective cladding.
- Structural Fire Safety: Deployed to significantly improve the fire-resistance rating of load-bearing assemblies, utility shafts, and spatial enclosures.
- Flooring & Interfloor Decks: Perfectly suited for dry floor screeds, continuous subfloor decking, and interfloor partitioning under various topcoats.
- High-Moisture Environments: Due to its excellent water resistance, CPB is an outstanding solution for lining bathrooms, showers, commercial kitchens, laundries, and unheated facilities.
- Roofing Systems: Utilized as a continuous rigid substrate for flat or sloped roofs, delivering additional mechanical strength and structural fire protection.

System Purpose
- Internal Thermal Insulation: Minimizing heat loss through perimeter walls when external alterations are prohibited (e.g., historical landmarks, architectural heritage, or local zoning restrictions).
- Acoustic Insulation: Ensuring maximum acoustic comfort by absorbing airborne sound within interior partitions and apartment-separating walls.
- Surface Leveling: The stud-and-runner frame configuration easily conceals structural irregularities of the existing backup wall.
Applications
Internal thermal and acoustic insulation systems are vital when external access to the facade is restricted or when creating custom interior microclimates is the priority:
- Inter-Room and Partition Walls: The core application focuses on acoustic insulation. Specialized sound-absorbing stone wool is placed within drywall frames to guarantee privacy in residential apartments, hotel rooms, and commercial offices.
- Internal Insulation of Exterior Walls: Choosing internal wall insulation is necessary when exterior facade insulation is technically impossible (e.g., zero-lot-line buildings, adjacent structures) or due to strict building preservation laws. Note: This system strictly requires a continuous, sealed vapor barrier to eliminate interstitial condensation risks.
- Non-Load-Bearing Partitions: Utilizing lightweight, high-performance slabs to eliminate the “hollow wall” resonance effect in metal or timber stud systems.
- Commercial & Specialized Zones: Perfect for building soundproof meeting rooms, executive offices, and isolated medical compartments within larger commercial footprints.
Frequently Asked Questions (FAQ)
What is the best material for internal partition wall insulation?
For stud partition frames and internal wall insulation, mid-density stone wool slabs (30–50 kg/m³) are ideal. Their open, fibrous structure provides the highest sound absorption coefficients, effectively capturing airborne noise and ensuring quiet interior spaces.
