DANOSA

Enhance sound performance in partitions, drainage systems, and mixed-use builds with Danosa’s advanced acoustic membranes:

• M.A.D. (Mass Acoustic Damping) PRO: An aluminised bituminous sheet for acoustic insulation designed for low-frequency acoustic absorption in floors and linings.
• ACUSTIDAN PRO is a three-layer acoustic membrane designed to block both low and high-frequency noise. Made with recycled fibres, a dense elastomeric sheet, and an aluminised finish, it offers excellent sound insulation and strong fire resistance.
• FONODAN: A self-adhesive bitumen/polyethylene strip installed between stud frames and plasterboard, reducing airborne sound and vibration in partitions.
• IMPACTODAN: Cross-linked polyethylene foam membrane ideal under floating screeds to minimise impact noise transmission.

Robust, torch-applied or self-adhesive SBS membranes that deliver long-term protection against water ingress:

• ESTERDAN Plus: A self-protected SBS capsheet with mineral finish, ideal for flat and inverted roof systems. Trusted in BBA-certified products.
• GLASDAN 30P Elast: A 3 kg/m² SBS underlay (torch applied), reinforced with fibreglass, used in roof waterproofing or as part of multilayer systems.

These products deliver strong tear resistance, UV protection, and wind uplift performance in both new-build and retrofit applications.

Complementary primers and membranes designed for efficient waterproof detailing:

• Bitumen Primer (e.g. Impridán, Curidán, Maxdan): Applied before membrane installation to ensure optimal adhesion of torch-on systems. Enhances long-term system integrity.

Danosa rigid XPS insulation boards deliver high compressive strength and minimal water absorption — perfect for inverted roofs, ground floors, and buried structures:

• DANOPREN TR: Closed-cell XPS available in standard and high-density grades (up to 300 kPa load resistance). Ideal for insulation beneath inverted roof finishes and heavy-duty flooring applications.

Durable drainage membranes combined with geotextile layers designed to protect waterproofing and manage moisture:

• DANODREN Garden: HDPE nodular drainage sheet with pre-bonded non-woven geotextile. Engineered for inverted green roofs and horizontal drainage applications.
• DANODREN H25 Plus: Deep profile HDPE drainage sheet, ideal for vertical basement walls and foundation drainage. Often used with Danofelt geotextile for subsurface moisture control.

Danosa combines innovation and technical performance across multiple building fabric solutions — from acoustic comfort to structural waterproofing to underground drainage. Its systems are BBA-certified, CE-marked, and widely supported in major UK building specifications.
