About

Rainscreen cladding at 75mm thickness plays a vital role in contemporary building construction. It functions as a protective barrier against weather exposure whilst supporting improved energy efficiency and indoor thermal regulation. This insulation is purpose-designed for installation beneath exterior cladding, establishing a ventilated air gap between the cladding layer and the structural envelope.

A key advantage of 75mm rainscreen cladding insulation is its superior moisture control capability. The ventilated cavity permits air movement between the cladding and insulation, preventing moisture accumulation and reducing risks of dampness, decay, and structural damage. This moisture management system significantly extends the durability of the building's external envelope.

Installation

1. Unilin 75mm Stonewool panels arrive in polythene-wrapped packs suitable for temporary outdoor storage. For longer-term storage, keep packs on raised platforms and protected from weather. When specified in the system design, additional membranes can provide extra protection. The high-density panels tolerate reasonable exposure during installation, though standard building practice recommends weather protection during construction whenever possible.
2. Key considerations when installing 75mm Unilin SW/RS panels:
3. These panels are manageable in weight and can be cut precisely using a fine-tooth saw or sharp utility knife. Accurate fitting between adjacent boards and around openings is essential for maximum thermal efficiency.
4. Creating tight joints between adjoining boards maintains continuity of the insulation layer.
5. During installation, arrange boards in a staggered break-bonded pattern with all joints firmly seated.
6. Use metal and polypropylene 'mushroom' type fixings with a minimum 75mm diameter to secure panels until the main cladding is fitted.
7. Account for all penetrations through the insulation layer in thermal calculations, particularly at floor edges and openings.

Handling, Cutting, and Storage:

1. Unilin Rainscreen Cladding Insulation should be positioned on a clean, level, raised surface and kept under protective covering.
2. Note that polythene wrapping alone does not provide adequate weather protection.
3. Take care to prevent damage to the insulation during storage and throughout the construction phase.
4. When handling 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.
