Petrarch reconstituted stone rainscreen panels are predominantly created from by-product material. Balancing natural beauty and the technical advantages of a modern man-made material, perfectly.
Petrarch reconstituted stone rainscreen facade in application:
As a cladding material manufactured from 80% by-product crushed marble and stone, Petrarch offers all of the beauty of real stone, with the added advantage of a modern material. Designed to withstand the most demanding of environments, Petrarch is highly durable and resistant to impact, graffiti, scratch and fire.
Petrarch reconstituted rainscreen cladding is suitable for a range of applications across every sector.
For rainscreen cladding applications:
Petrarch has been designed and installed as a rainscreen cladding system with open and closed joints in many developments across multiple construction sectors throughout the UK, Europe and the US.
The air gap from face of insulation to rear of the Petrarch reconstituted stone panels must be a minimum of:
Petrarch cladding - Over 1500 colours and 5 distinctive textures:
There are an astounding 1500+ colours in our Petrarch rainscreen colour palette, offering a plethora of versatile design options. Whether you want to blend in, or stand out, this flexible rainscreen cladding solution offers so much potential.

Technical Advantages of Petrarch engineered stone rainscreen cladding:
Petrarch is a reconstituted stone rainscreen facade, created primarily from natural by-product materials such as stone and marble. Technically strong, Petrarch rainscreen panels offer an A2-s1,d0 reaction to fire rating (EN 13501-1).
Highly durable and impact resistant, it is considerably lighter than natural stone and cement based systems. This unique alternative to stone cladding is highly weather resistant, yet just like natural stone, Petrarch reconstitutes stone rainscreen facade mature over time, giving character and depth to any architectural scheme.
Petrarch reconstituted stone rainscreen facade is manufactured in the UK where the product has been supplied to the rainscreen industry for over 50 years and to this day remains the natural choice when specifying rainscreen cladding which balances competing and exacting specification criteria.
Features and benefits of Petrarch reconstituted stone panels:
Unique Surface Characteristics:
An aesthetic as unique and appealing as natural stone. Thanks to Petrarch rainscreen panels' unique manufacturing process, the surface takes on an open texture, which can be seen on the face of the panel post pressing, whilst in production the surface pattern emulates distinctive marble effects - creating completely random patterns meaning that there will be areas with a higher or lower density of each marble colour.
These nuances enhance its ‘natural stone’ aesthetic and does not affect its integrity. Matt or honed finishes are achieved by removing the surface layer of Petrarch rainscreen cladding panels; exposing the core texture for a distinctive stone- like look.
Petrarch Reconstituted Stone Rainscreen Facade Core & Surface:
As Petrarch is manufactured with a homogeneous reinforcement the product will not delaminate and is immune to both insect and vermin attack. Additionally a pressure moulded manufacturing process creates a high-density panel which is unaffected by freeze-thaw degradation due to a surface which is virtually non-porous with a water absorption ratio of less than 0.2% after a 24h immersion. Petrarch reconstituted stone cladding panels are hereby ideal for the UK construction market thanks to these excellent weather resistant qualities.
Petrarch rainscreen facade in application:
A non-loadbearing external wall assembly comprising two layers.
A protective outer skin of rainscreen cladding panels and an insulated and airtight backing wall both separated by a ventilated cavity.
Types:
Closed jointed - back ventilated and drained system
Ventilation is achieved by openings at top and base of the rainscreen cladding. Moisture build-up at rear of panels will be either drained at the base or thermally evaporated.
Open jointed - Pressure equalized system:
When the outside air pressure is transferred to the air cavity behind the cladding panel, the cladding is exposed to a near-zero pressure differential thus avoiding wind driven rain getting into the cavity through the open joints. A compartmented air cavity is required.
