About

Rainscreen cladding at 50mm thickness plays a vital role in contemporary building construction. It functions as a protective barrier against weather exposure whilst supporting thermal efficiency and interior comfort levels. This specialised insulation product is positioned behind the exterior cladding, establishing a ventilated air gap between the outer cladding layer and the building fabric.

A key advantage of 50mm rainscreen cladding insulation is its superior moisture management capability. The ventilated cavity permits air movement between the cladding and insulation, preventing moisture accumulation and reducing risks of mould, decay, and structural damage. This moisture control system significantly extends the durability of the building envelope.

Installation

1. Unilin 50mm Stonewool panels arrive in polythene-wrapped packaging suitable for short-term outdoor storage. For longer storage periods, keep packs elevated and protected from weather conditions. When specified within the system design, breathable membranes provide additional protection. The high-density composition allows reasonable exposure during installation, though standard construction practice recommends weather protection whenever possible.
2. Key considerations when installing 50mm Unilin SW/RS panels:
3. These panels are lightweight and can be trimmed using a fine-tooth saw or sharp utility knife. Accurate fitting against adjacent boards and around openings is essential for maximising thermal performance.
4. Tight joints between adjoining boards maintain continuity of the insulation layer.
5. During installation, arrange boards in a staggered break-bonded pattern with all joints firmly closed.
6. Use metal and polypropylene 'mushroom' type fixings with a minimum 70mm diameter to secure panels until the main cladding system is fitted.
7. Account for all penetrations through the insulation layer in thermal calculations, particularly at floor interfaces and openings.

Handling, Cutting, and Storage:

1. Unilin Rainscreen Cladding Insulation should be stored on a clean, level, raised surface and kept under protective covering.
2. Note that polythene wrapping alone does not provide adequate protection against weather exposure.
3. Take care to prevent damage to the insulation during storage and throughout the construction phase.
4. When handling the insulation board, always use appropriate personal protective equipment (PPE).

Certification and Standards:

1. BBA Certification Number: 10/4803.
2. Compliance with BS EN ISO 9001 Quality Management System.
3. Adherence to BS EN ISO 14001 Environmental Management System.
4. Conformance with BS EN 13166 standards.
