The P-55 Evolution curtain wall system makes your life easier. 33% faster to install, with the use of only one tool and without sealant !

Impressive energy efficiency

You get a 55% higher energy efficiency than with a conventional curtain wall frame. This system meets equivalent energy performance to Energy Star 2016 standards. 

100% watertight, without sealant !

Simplify and accelerate on site installation time ! With 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.

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!

Simplified installation and greater expansion

  • Easy installation and perfect adjustment, thanks to specially designed factory installed fixing pins
  • Sealant free and water tight horizontal expansion joint made of EPDM
  • Expansion joint offers a greater expansion (38 mm vs 12mm on a regular system) and can act as a floating head

Innovative acoustic absorption

The P-55 curtain wall reduces sound transmission by up to 11.2 dB* on certain frequency spectrums (ex: Urban traffic).  

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