HOLCIM VENT EXTRA FB
Product Description
HOLCIM VENT EXTRA FB are non-combustible stone wool boards with a disturbed fiber arrangement, designed for use in ventilated facades where the highest level of safety, durability, and aesthetics are essential. Thanks to their increased density and durable black glass veil, they are the ideal solution for the most demanding projects, including those involving slotted and transparent facade cladding.
They are perfect for applications where the design requires the best thermal, acoustic, and fire protection – without compromise.

Główne zastosowania i kluczowe właściwości
Usage
Key properties
- Outer layer of thermal and acoustic insulation for ventilated facades with semi-transparent cladding or visible gaps (e.g., perforated panels, aluminum slats, facade boards)
- Buildings with the highest technical requirements – multi-family, office, industrial, and public utility buildings
- New investments and thermal modernization
- Frame walls and other vertical structures exposed to wind and changing weather conditions
- Highest technical class – excellent performance, strength, and durability
- Black glass veil – improves aesthetics and protects against air leakage from the stone wool space
- High density and rigidity of the boards – ideal installation stability, even at high altitudes
- Fire reaction: class A1 – non-combustible product
- Declared thermal conductivity coefficient λD = 0.034 W/mK – the most effective barrier against heat loss
- Very good acoustic properties – reduction of external noise, improved user comfort
- Vapor permeability – allows the partition to “breathe,” reducing the risk of water vapor condensation
- Water repellency – the boards do not absorb water, maintaining their thermal insulation properties
