• Secure in place using staples, wire, or friction fit as appropriate

What is Earthwool Insulation?

Earthwool insulation is a high-performance mineral wool product made from recycled glass and sand, using ECOSE Technology, a bio-based binder. It delivers superior thermal insulation and acoustic soundproofing, helping to reduce energy bills and create quieter interiors. Non-combustible and safe, it is designed for easy handling and installation, being softer and free from added dyes or formaldehyde. Ideal for walls, floors, and ceilings, Earthwool supports sustainable building practices while improving comfort and safety in both residential and commercial projects.

Why is it called Earthwool?

It is called Earthwool because the insulation is made primarily from natural and recycled materials, like recycled glass and sand, combined in an environmentally conscious way using ECOSE Technology, a bio-based binder. The name highlights its eco-friendly, sustainable nature (“Earth”) and the fibrous, wool-like structure of the material (“Wool”), which gives it softness, flexibility, and easy handling compared to traditional insulation.

In short, “Earth” = sustainable/mineral-based, “Wool” = soft, fibrous insulation.

What does APR stand for?

APR stands for Acoustic Performance Roll. It indicates that the insulation is specifically designed to enhance soundproofing and reduce noise transmission in buildings. The APR designation highlights that the product is optimised for acoustic applications, such as walls, floors, and ceilings, while still providing thermal insulation and fire safety.

Why is APR insulation better than other insulation products on the market?

When comparing APR insulation like Knauf Earthwool Acoustic APR to “others on the market,” we are generally referring to other common insulation types used for walls, floors, and ceilings, including:

1. Traditional fiberglass insulation rolls or batts – Often less soft, may contain formaldehyde or dyes, and can be harder to handle.
2. Standard mineral wool / rock wool insulation – Good fire resistance but may be denser, harder to cut, and less comfortable to install.
3. Foam board or rigid insulation panels – Excellent thermal performance but limited acoustic absorption and can be difficult to fit in irregular spaces.
4. Blown-in cellulose or fibreglass insulation – Effective in filling cavities but requires professional installation and may settle over time.

The key advantages of APR insulation over these alternatives are:

• Softer, easier handling with no added formaldehyde or dyes
• Enhanced acoustic performance for noise reduction
• Fire-safe A1 rating
• Quick installation in roll format
• Sustainable, eco-friendly materials
