Acoustic performance
The superb acoustic performance of Isonat helps to substantially surpass the requirments of the Building Regulations.

Fire performance
The fibres used in the production of Isonat are treated with a harmless ammonium salt to achieve a Euroclass E (B2) fire performance rating. Isonat complies with the fire performance requirements of the Building Regulations.

Technical Approvals
Isonat has been extensively tested in the UK and France, and has been approved for use by the French building and construction technical approval body (Centre Scientifique et Technique du Batiment - CSTB)

Durability
When used appropriately Isonat can be expected to last for the life of the building. Isonat does not attract rodents or moths.

Resistance to settlement
The high density, fibre toughness and bonding structure of Isonat creates a product with high loft and an inherent ability to resist settlement.

Moisture control
The ability of Isonat to absorb and release humidity actively assists the control of moisture in buildings without any loss in thermal performance, and without affecting the durability of the insulation.

How to use
Isonat is designed for use as thermal and acoustic insulation in walls, roofs and floors. The high density and high flexural strength makes the product tight-fitting and slump resistant.

Environmental Performance
The need for more sustainable approaches to the construction and use of buildings is now almost universally recognised. Isonat has been developed to enable home owners and specifiers to meet exceptionally high performance and environmental standards

Human Health
Isonat is made from healthy natural fibres which do not irritate the eyes, skin or respiratory tract. The use of natural non-toxic building materials will make your home a healthier place to live.

Research and Development
We are committed to a continuous programme of research and development activity. The key aims of this programme are technical improvement, cost reduction and performance analysis.
