Introduction

This document provides detailed technical specifications and performance data for Fermacell independent wall linings, focusing on steel and timber frame systems. It covers fire protection, sound insulation, thermal performance, and installation guidelines for various wall lining configurations.

System Specifications and Performance Details

The document categorizes wall lining systems by grades (e.g., 3S01, 3S11, 3S12, 3S21, 3S31) and provides key parameters including wall weight (kg/m²), wall height (m), wall thickness (mm), fire rating (minutes), sound insulation improvement (ΔR dB), and thermal resistance (m²·K/W). The systems use DIN standard studs at 600 mm centers with varying stud depths (50 mm, 75 mm, 100 mm, 125 mm) and different Fermacell board facings (12.5 mm, 15 mm, 10 mm layers).

Steel Frame Wall Linings

• Grades 3S01 to 3S31: These systems vary in stud size, board thickness, and insulation type (mineral wool densities from 30 to 40 kg/m³). Fire ratings range from non-rated to 90 minutes, with sound insulation improvements up to ≥22 dB.
• Facings: Single or multiple layers of Fermacell boards, including Powerpanel H2O for wet areas.
• Insulation: Mineral stone wool insulation thickness varies from 20 mm to 100 mm depending on system and performance requirements.

Wet Area Wall Linings

• Use of Fermacell Powerpanel H2O boards designed for moisture resistance.
• Systems such as 3S01 H2O, 3S02 H2O, and 3S11 H2O provide fire ratings up to 30 minutes with appropriate insulation.

Wall Liner Systems (3WS Series)

• Designed for severe conditions with stud walls and mineral wool insulation.
• Fire ratings up to 60 minutes and sound insulation ratings (RL,W) up to 62 dB.
• Thermal resistance values range from 0.53 to 1.31 m²·K/W.

Variable Cavity Wall Linings (3WH Series)

• Use battens of varying sizes (30x50 mm, 40x50 mm, 60x40 mm) at 600 mm centers.
• Facings include one or two layers of Fermacell boards with mineral wool insulation.
• Fire ratings up to 60 minutes, sound insulation up to 63 dB, and thermal resistance up to 1.57 m²·K/W.

Key Parameters and Recommendations

• Stud Spacing and Size: Standard 600 mm centers with stud depths from 50 mm to 125 mm depending on system.
• Board Thickness: Typically 12.5 mm or 15 mm Fermacell boards; some systems use additional 10 mm layers for enhanced performance.
• Insulation: Mineral wool densities between 20 and 40 kg/m³, thickness from 20 mm to 100 mm, critical for fire and sound performance.
• Fire Ratings: Systems provide fire resistance from non-rated up to 90 minutes, with some classifications from both sides.
• Sound Insulation: Improvements (ΔR) range from 20 dB to over 22 dB; sound reduction levels (RL,W) up to 63 dB.
• Thermal Performance: Thermal resistance values (k/W) vary by system and insulation thickness, with higher values indicating better insulation.

Installation and Additional Information

Installation details are referenced to the Fermacell Handy Guide, emphasizing correct fixing and finishing techniques for optimal performance. The document also mentions components and accessories relevant to wet areas, rainscreens, timber frames, fire protection, flooring, ceilings, linings, and partitions.

Summary

This technical document serves as a comprehensive reference for selecting and specifying Fermacell wall lining systems in steel and timber frame constructions. It provides critical data on fire resistance, sound insulation, thermal performance, and structural parameters to guide design and installation decisions in various building applications, including wet areas and high-performance partitions.
