This product has multiple variants. The options may be chosen on the product page While all insulation will improve acoustic performance to some extent, purpose-designed acoustic insulation between floors is more effective for serious noise control. Another option is to install ceiling insulation between floors. Although typically used for ceilings, these products can also work well between floors, enhancing both acoustic and thermal comfort. Whether you choose acoustic or ceiling insulation for your mid-floor section, both will help improve energy efficiency, create distinct zones in your home and reduce noise transfer.
Thermal Insulation Options for Between Floors
Thermal insulation between floors helps regulate temperature across the space and improves energy efficiency.
- Fibreglass Batts: Affordable and a popular choice. They are widely used for their thermal performance.
- Polyester Batts: Perform well, are soft, easy-to-handle and are often made from recycled materials, making them ideal for eco-conscious builders.
- Foam Boards: Offer high R-values in slim profiles, making them great for tight spaces or extreme climates.
How Acoustic Insulation Reduces Noise Between Floors
Acoustic insulation between floors reduces noise transmission between levels, enhancing comfort and privacy.
- Glasswool: Great for absorbing airborne noise.
- Polyester: A soft, easy to handle option with noise-reducing properties.
- Mineral Wool/Rockwool: Excellent for both acoustic and thermal control.
- Acoustic Foam Panels: Often used as an additional treatment in media rooms or home cinemas for targeted surface sound control. However, they are typically installed alongside bulk insulation, not as a substitute for it within mid-floor cavities.
Understanding R-Value for Insulation Between Floors
An R-value measures how well insulation resists heat flow, the higher the R-value, the better the thermal performance. For insulation between floors in Australia (for a general home), R2.5-R3.5 is typically recommended. You are required to use at least the minimum R-v
