WALL INSULATION THICKNESS OPTION

Choosing the Right Thickness: 70mm, 90mm, or 140mm Wall Insulation

Home wall insulation is available in three main thicknesses to suit the depth of your wall framing: 70mm, 90mm, and 140mm. Selecting the correct thickness is crucial for a secure fit and optimal performance.

 

Why is Matching Insulation Thickness Important?

  • Ensuring the insulation matches the depth of your wall cavity guarantees a snug fit, preventing gaps and reducing the risk of insulation slumping or losing effectiveness over time.

  • Avoid compressing thicker insulation into smaller cavities, as this diminishes its insulating properties 

 

Where to Install Each Thickness:

  • 70mm Residential wall insulation: Best suited for older homes with narrower framing. Limited R-value options, typically ranging from R2.0 to R2.2.

  • 90mm Wall insulation products: The most common option for standard timber framing in modern construction. Available in R-values from R2.2 to R2.8.

  • 140mm Energy-efficient wall insulation: Ideal for homes with deeper wall framing, often used in high-performance or energy-efficient builds. Provides superior thermal performance with R-values from R2.9 to R4.3.



How do you choose the right Sized Wall Insulation?

- Choose the highest R-value available for your framing depth to maximize energy efficiency and comfort.

- Consider your climate zone to determine the minimum R-value requirements, ensuring compliance with local building codes.

 

Available in R-values from R2.2 to R2.8. 140mm thermal barrier for walls: Ideal for homes with deeper wall framing, often used in high-performance or energy-efficient builds. Provides superior thermal performance with R-values from R2.9 to R4.3. How do you choose the right Sized Wall Insulation?
