Ventilated Façade Systems (Rainscreen Cladding)

Ventilated façade systems—commonly referred to as rainscreen cladding—are high-performance external wall solutions designed to deliver superior thermal efficiency, moisture control, and architectural flexibility. These systems are widely used in both new-build and retrofit projects, particularly where modern aesthetics and compliance with fire safety regulations are essential.

System Overview

A ventilated façade is a dual-layer cladding system that separates the insulation and weather protection functions. The outer cladding acts as a shield against rain and wind, while a rear ventilation cavity allows air to circulate between the cladding and the insulation. This airflow helps regulate moisture, prevents condensation, and promotes a healthier building envelope.

Insulation Layer

The insulation layer typically consists of Mineral Wool, chosen for its non-combustible properties, excellent thermal performance, and breathability. It is mechanically fixed to the substrate and forms a continuous thermal envelope that significantly reduces heat loss and improves energy efficiency.

Mineral Wool: Fire-resistant, vapour-permeable, and ideal for buildings requiring enhanced safety and sustainability.

Subframe System

A metal subframe is installed over the insulation to support the cladding panels. This framework includes vertical and horizontal profiles, brackets, and wall holders, often incorporating thermal breaks to minimise cold bridging. The subframe allows for concealed fixing, improving aesthetics and simplifying installation.

Cladding Panels

The outer layer consists of cladding panels made from a variety of materials, including:

Fibre cement

High-pressure laminate (HPL)

Ceramic

Natural stone

Metal composites

Glass

These panels are available in a wide range of colours, textures, and formats, offering extensive design flexibility. Fixing methods include undercut anchors, mechanical clasps, or adhesive systems, depending on the material and design intent.

Ventilation Cavity

The rear ventilation cavity is a critical component of the system. It allows ambient air to flow behind the cladding, creating a chimney effect that removes moisture and helps dry out the external wall. This improves the longevity of both the insulation and the building structure.

Ventilated façade systems offer a combination of technical performance, aesthetic versatility, and long-term durability. They are ideal for projects requiring compliance with fire, acoustic, and thermal regulations, and are especially suited for buildings where modern design and high energy efficiency are priorities.
