P-55 Evolution

Water tight curtain wall, no silicone required !

The P-55 Evolution is a durable choice. Since its sealant gaskets do not deteriorate over time, they keep their amazing properties. Made of closed-cell foam (EPDM), they are auto-sealing and ensure a flawless and fast 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 risks of errors and surprises on site

The patented FLEXJOINT-55 expansion joint is designed to provide on site flexibility. Made of long lasting EPDM and requiring no seallant, it allows for a greater expansion (38 mm vs 12mm for a regular system) and can acct as a floating head. Just like the rest  of this system, it is easy to install.

Design flexibility

All Prévost products are compatible with the P-55 Evolution curtain wall system. Opening vents, skylights and doors can all be integrated flawlessly, we offer a wide variety of caps and finishes to suit your vision. We believe creativity should not be limited by technical considerations.
