Product innovations and technical attributes of Knauf Insulation
Thermal, fire, and acoustic performance of Knauf Insulation materials
Knauf Insulation is unique in the UK market for manufacturing both glass and rock mineral wool, enabling tailored solutions for different building needs. Its glass and rock wool products achieve robust thermal performance characteristics, with U-values commonly from 0.035 to 0.040 W/m·K—vital for reducing heat loss. They’re classified as non-combustible (A1 Euroclass), delivering peace of mind for fire resistance properties in homes and public buildings. Acoustic insulation products, including Knauf Acoustic Roll, excel at limiting sound transmission, fostering quieter, more private environments.
Product-specific features: Rocksilk® RainScreen, OmniFit®, DriTherm®, and advanced insulation boards
Rocksilk® RainScreen Systems feature dual-density slabs. These permit render application externally while masking wall irregularities inside, benefiting both performance and aesthetics. OmniFit® stands out as a lightweight, low-carbon alternative to conventional rockwool, delivering thermal, fire, and acoustic ratings suitable for residential and commercial walls, lofts, and floors. DriTherm® Cavity Slabs combine moisture management with effective insulation, ideal for cavity wall installations.
Technical specifications including U-values, thickness, and dimensions; comparison with alternative brands
Insulation roll options are available from 10mm up to 20mm thickness, with larger roll packs serving broad coverage needs (up to nearly 200m² per pallet). Knauf’s boards and slabs adapt to various spaces: 455mm-wide cavity slabs, 2.4m-long plasterboards, and specially sized advanced insulation boards to meet specific project criteria, providing a practical advantage in both renovations and new builds.
Sustainability, Installation Guidance, and Application Benefits
Sustainability and Eco-Friendly Credentials of Knauf Insulation
Knauf Insulation prioritizes sustainability by incorporating both recycled and natural raw materials into its products. Glass and rock mineral wool solutions are manufactured with eco-friendly intent, utilising high proportions of recycled glass and basalt rock, along with repurposed materials from industrial processes such as steel production. The adoption of innovative Ecose® technology—a binder made from rapidly renewable materials—reduces embodied carbon and enhances the green profile of their offerings. Knauf’s commitment to carbon-neutral manufacturing and minimised environmental impact is underscored by BBA certification and a transparent stance on resource conservation.
Step-by-Step Installation, Handling Best Practices, and Regulatory Compliance
Insulation rolls and boards from Knauf are designed for easy handling and precise fitting. Installers are advised to cut materials with sharp tools, wear protective equipment, and avoid compressing the mineral wool to maintain thermal and acoustic properties. For both new builds and renovations, compliance with UK building regulations—including fire and height safety standards—is ensured by product certifications, such as the Euroclass A1 rating for fire-resistance. Detailed guides support safe storage, transport, and installation, enabling both professionals and DIYers to achieve optimum results.
Practical Benefits for Residential and Commercial Properties
Knauf’s mineral wool and rock wool insulation deliver substantial advantages:
- Energy efficiency: Enhanced thermal resistance lowers heating costs.
- Soundproofing: Acoustic rolls and boards reduce noise transfer between rooms.
- Moisture resistance: Slabs and panels resist condensation, mold, and mildew.
- Longevity: Durable construction assures effective performance for years under demanding conditions in both homes and commercial spaces.
