What is Wood Fiber Insulation?

Wood fiber insulation is a high-performance, eco-friendly material made from natural wood fibers, often sourced from sawmill by-products. It’s manufactured using sustainable processes that retain the wood's natural insulation properties while enhancing durability and resistance to the elements. Whether in the form of rigid boards or flexible batts, wood fiber insulation offers excellent thermal, acoustic, and moisture control — ideal for those seeking a green building solution.

Our collection features industry-leading products designed to meet diverse insulation needs:

• TimberHP TimberBatt: High-performance batts with R-4 per inch, ideal for walls and ceilings.

• TimberHP TimberFill: Loose-fill insulation offering ~R-3.8 per inch, perfect for attics and hard-to-reach areas.

   

Benefits of Wood Fiber Insulation

• Sustainable & Renewable: Sourced from FSC-certified wood, it’s biodegradable, recyclable, and produced with minimal environmental impact.
• High Thermal Performance: Provides superior thermal insulation, reducing energy consumption and maintaining comfortable indoor temperatures year-round.
• Excellent Acoustic Insulation: Naturally dense structure effectively dampens sound, making it perfect for both residential and commercial environments.
• Breathable Material: Allows water vapor to pass through without retaining moisture — ideal for timber frame buildings and breathable wall systems.

• Carbon Negative Potential: Acts as a carbon sink during its lifecycle, contributing to a lower carbon footprint in construction projects.

   

Wood Fiber Insulation Selection Guide

When choosing the right wood fiber insulation, consider the following:

• Application Area – For internal walls opt for flexible batts; for roof and façade insulation, rigid boards like Gutex Multitherm or Steico Universal are ideal.
• Thermal Conductivity – Look for low lambda values (typically around 0.038–0.043 W/m·K) for better insulation.
• Board Thickness – Ranges from 20mm to 200mm. Thicker boards offer enhanced thermal resistance (R-value).
• Installation Method – Choose boards with tongue and groove profiles for tight-fitting exterior applications.

• Fire & Moisture Resistance – Consider water-repellent and fire-rated variants for exposed or high-risk areas.

   

Practical Applications of Wood Fiber Insulation

• Roof Insulation – Rigid boards like Gutex Multitherm are ideal for sarking beneath tiles or metal roofing.
• External Wall Insulation (EWI) – Used in render systems or ventilated cladding façades to improve the thermal envelope.
• Internal Wall & Floor Soundproofing – Flexible batts dampen noise in partition walls and between floors.
• Timber Frame Construction – Provides breathable insulation within wall cavities and sheathing layers.

• Retrofit Projects – Lightweight and easy to cut, making it suitable for upgrading existing buildings without a structural overhaul.
