ES 45Pa

Eco System 45 'Parallel' window

A new dimension of affordable quality

Eco System® 45Pa is a non-insulated system for inward and outward opening windows, designed according to the highest European quality standards. To guarantee superior quality and performance in every situation, the window system has three gasket levels for inward and outward opening windows. Through intelligent application, these multiple gaskets meet even the high air- and water tightness requirements of tropical regions. This simple, yet highly innovative design offers a very cost-efficient solution thanks to its optimised fabrication process.

ES 45Pa can be realised with all types of inward and outward opening windows, with an extensive choice of accessories. The numerous combinations of elements and the perfect match with the ES 45Pa door –and sliding system, make ES 45Pa extremely suitable for all types of building concepts. As with all Reynaers systems, a 10-year guarantee is offered.
