Ventilated rainscreen facades

What is a ventilated rainscreen facade? The cladding is fixed to the wall on a metal substructure, and an air gap is left between the cladding and the insulation through which moisture escapes. Such a facade protects the wall and insulation, allows cladding to be installed in a wide range of weather conditions and lets individual elements be replaced. Russian project documentation often lists it (NVF) next to SPK — glazed translucent structures; together they form the building envelope.This section has articles on ventilated facade build-ups and substructures made of aluminium, galvanised steel and stainless steel; on cladding with GFRC (glass fibre reinforced concrete), stone, porcelain stoneware, composite and fibre cement; on insulation, wind barriers and fire breaks; on load calculation and anchor testing; and on facades for high-rise housing, business centres, hotels and public buildings.Ventilated facade installation is covered on the Construction and facade works page.

Ventilated Rainscreen Facade: Structure and How It Works

A ventilated rainscreen facade is an external cladding system in which the finishing material is fixed to the wall via a metal substructure, set away from the insulation. A ventilated air gap remains between the insulation and the cladding, through which moisture escapes from the wall and insulation. Cladding options include porcelain stoneware, glass fibre reinforced concrete (GFRC), natural stone, fibre cement and metal panels.The main criterion for choosing a system is that the substructure, insulation and cladding are compatible with each other and meet the fire safety and load requirements for the particular building. Rainscreen facades are used on multi-storey residential buildings, office and public buildings, in refurbishment, and on private houses. All articles on the topic are in the section Ventilated rainscreen facades.

Rainscreen Substructures: Aluminium, Galvanised and Stainless Steel

A rainscreen substructure is a metal framework fixed to the load-bearing wall that holds the cladding away from the insulation, forming the ventilated gap. It consists of brackets, rails, anchors and cladding fixings and is made of aluminium alloys, coated galvanised steel or stainless steel.The main selection criterion is calculation: the substructure must carry the weight of the cladding and the wind load of the particular building with a margin, must not corrode in service, and must have confirmed compliance with the requirements for facade systems. The choice depends on the cladding, building height, climate and substrate. All articles on the topic are in the section Ventilated rainscreen facades.

Ventilated Rainscreen Facade Clad in GFRC

A GFRC (glass fibre reinforced concrete) ventilated facade is a rainscreen system in which the cladding consists of thin-walled panels and architectural elements made of GFRC, fixed to a metal substructure with an air gap over the insulation. The material is chosen when a facade needs plasticity — cornices, pilasters, window surrounds, rusticated surfaces, large relief panels — while the cladding must remain non-combustible and relatively light.The key selection criterion is not the panel itself but the combination of panel, cast-in fixings and substructure, engineered for a specific building. The solution suits residential complexes, hotels, public and office buildings where the architect works with a classical or neoclassical order or with a sculptural contemporary form.General principles of rainscreen systems are covered in the Ventilated rainscreen facades section; this article focuses on what sets GFRC apart.

Natural Stone Ventilated Facade

A natural stone ventilated facade is a rainscreen system in which stone slabs are fixed to a metal substructure with clips or anchors, leaving an air gap between the cladding and the insulation. The stone is not bonded to the wall, so it is unaffected by the wall's moisture and movement, and the wall works with insulation on the outside.The key selection criterion is the stone type and slab thickness for a specific fixing detail: not every stone that looks good indoors will withstand wind, frost and point loads on its edge. This solution is chosen for buildings with a long life cycle — premium residential buildings, public and office buildings where the texture of real stone matters.The general logic of rainscreen systems is covered in the Ventilated rainscreen facades section.

Porcelain Stoneware Ventilated Facade

Porcelain stoneware cladding in a ventilated rainscreen facade means fixing porcelain slabs to a metal substructure with an air cavity in front of the insulation. Porcelain stoneware is dense fired ceramic with very low water absorption, so it withstands frost and rain, and a flat slab of standard format makes installation predictable.The main selection criterion is the combination of format, slab thickness and fixing method: it determines the look of the facade and the weight and cost of the substructure. Porcelain stoneware is chosen for residential complexes, office and public buildings that need a flat, maintainable facade without complex modelling, and for plinths and individual surfaces combined with GFRC or stone.General principles of rainscreen systems are covered in Ventilated rainscreen facades.

Composite Cassette Ventilated Facade: Pros and Limitations

Composite facade cassettes are cladding elements folded from aluminium composite material (ACM): two thin aluminium sheets with a core of polymer or mineral filler. Cassettes are fixed to the ventilated facade substructure on hooks or rivets, form a flat plane with crisp joints and put almost no load on the wall.The key selection criterion is the core type and the confirmed fire hazard class of the system: it determines where composite can be used at all. Composite cassettes are chosen for retail and office buildings, petrol stations, inserts and portals that need light cladding with a bright plain surface, where modelling and stone texture are not required.Composite's place among other claddings is described in the Ventilated rainscreen facades section.

Fibre Cement Panels for Ventilated Facades

Fibre cement panels are flat facade boards made of cement reinforced with cellulose or synthetic fibres, with mineral fillers. In a ventilated facade they are fixed to the substructure with screws, rivets or concealed clips and provide a flat painted or textured surface at moderate weight.The key selection criterion is the building's use and height: fibre cement suits residential buildings, detached houses, administrative and warehouse buildings that need inexpensive non-combustible or low-combustibility cladding without modelling. If three-dimensional elements or stone texture are required, GFRC or natural stone is usually chosen.Fibre cement's place among other claddings is in the Ventilated rainscreen facades section.

Ventilated Facade Installation: Stages of Work

Installing a ventilated rainscreen facade is a sequence of work in which each layer covers the previous one: preparation and survey, brackets, insulation and membrane, rails, cladding, acceptance. A mistake made at an early stage cannot be corrected later without dismantling, so quality is determined not by how fast panels are hung but by control of concealed works.The main criterion for choosing a contractor is whether they work to the design and the system's technical details manual and hand over concealed works with signed inspection records. This article is useful for clients, general contractors and technical supervision planning and accepting rainscreen facades on multi-storey and public buildings.The system itself is described in Ventilated rainscreen facades.

Ventilated Facade Insulation: Materials and Thickness

Insulation behind a ventilated rainscreen facade is made with non-combustible mineral wool boards fixed to the wall with insulation dowels and, where required, covered with a wind barrier membrane. A ventilated cavity is left over the insulation to remove moisture, so the board stays dry and keeps its thermal performance.The main selection criteria are the density and intended use of the board (for rainscreen facades, not for rendered facades or roofs) and a thickness confirmed by thermal calculation for the specific region and wall. This article is useful for designers, clients and technical supervisors of multi-storey and public buildings, and for private home owners choosing an insulated rainscreen facade.The general logic of the systems is covered in the Ventilated rainscreen facades section.

Wind Barrier Membrane in a Ventilated Facade

A facade wind barrier membrane is a vapour-permeable sheet laid over the insulation in a ventilated rainscreen system. It prevents the airflow in the ventilation gap from eroding fibres and cooling the mineral wool, protects it from water droplets, and at the same time lets water vapour pass from inside the wall to the outside.The key selection criterion is not the price per roll but whether the membrane matches the facade system in vapour permeability, UV resistance and, above all, fire performance. The question is relevant to designers, general contractors and technical supervisors, as well as to clients comparing rainscreen facade estimates.The membrane's place in the overall construction is described in the Ventilated rainscreen facades section.

Fire Barriers and Ventilated Facade Fire Requirements

Fire barriers in a ventilated facade are steel elements that close off the air gap between the insulation and the cladding around window and door openings and, in some systems, at every floor. Their job is to stop flames from a burning room getting into the ventilation gap and spreading up the facade as if through a chimney.The key criterion is that fire barriers must match the album of technical solutions of a system that has passed fire tests: material, thickness, projection, fixing spacing and locations are not chosen by eye. The topic matters to designers, technical supervisors and general contractors, as well as to clients who will go through design review and commissioning.The general construction of rainscreen facades is in the Ventilated rainscreen facades section.

Technical Certificate and Technical Assessment for a Ventilated Facade System

A technical certificate for a facade system is a federal-level document confirming that a ventilated rainscreen system is fit for use in construction in Russia. It is issued not for an individual bracket or panel but for the system as a whole: substructure, cladding, insulation, membrane, fasteners and details described in the album of technical solutions. Alongside the term "technical certificate" (TS), the industry uses the notion of a technical assessment of fitness (TO) — check the current form of the document and the procedure for obtaining it in official sources of the Russian Ministry of Construction.The key criterion is that the facade on site must match what is described in the certificate and album: materials, details and scope of application. This topic matters to designers, reviewers, technical supervisors and clients who want to avoid comments during design review and commissioning.Context is in the Ventilated rainscreen facades section.
