P-55 Evolution

Watertight, without silicone !

The P-55 Evolution offers lasting quality. Thanks to the patented OTOBLOCK-55 gaskets, glass walls built with the P-55 Evolution system are watertight, without the use of any sealant. Made with the closed cell foam technology (EPDM), joints seal guaranty a watertight installation every time.

The curtain wall that exceeds all standards

The P-55 Evolution’s unique design gives it a 55% higher energy efficiency than a conventional curtain wall frame. Thermal conductivity is limited so users inside the building are comfortable, even when close to the mullion, whatever the outside temperature.

This system has best energy efficiency. It helps reaching standards like NOVO CLIMAT 2 and Energy Star as well as getting LEED points.

Peace of mind ensured by a job well done

The P-55 Evolution is easy and fast to install, with the use of only one tool. All its components are thoughtfully designed to reduce the risk of errors on site. Extraordinary performance should never be overshadowed by installation problems.

Quietude for all

The P-55 curtain wall frame reduces sound transmission by up to 11.2 dB* on frequency 

spectrums less impacted by glass (ex: Urban traffic).

Improves STC (Sound Transmission Class) by up to 2 STC* in comparison with a traditional curtain wall.

* tested by an independent lab

 

Ideal for multi-storey buildings

Where comfort and quietude are priorities, the horizontal patented FLEXJOINT-55 expansion joint creates a rupture in the vertical mullions, reducing the spreading and transmission of noise between floors.

No maintenance necessary

No more water marks on glass surfaces! The patented integrated and invisible EVAC-55 water exhaust system directs the water flow towards the evacuation holes, forcing it to flow downwards along the vertical pressure plate and evacuates it at the base of the system, without creating water marks on the windows!

Reducing the risk of errors and surprises on site

The patented FLEXJOINT-55 expansion joint is designed to provide on site flexibility. It allows for a greater movement of 38mm (versus 12mm for regular systems) and can act as a floating head. Made of long-lasting EPDM, requiring no sealant and, just like the other components of the P-55, easy to install.

Freedom of design

All Prévost products are compatible with the P-55 Evolution system. Integrate opening vents, doors, skylights, choose caps and finishes that fit your vision… We believe your creativity should have no technical boundaries
