Energy efficiency and sustainable development: curtain walls that make all the difference!

These days, architecture is about much more than beauty and design. Buildings need to be smart, efficient, and green. That’s where Epsylon curtain walls come in. These glass façades that adorn myriad modern buildings don’t just make them visually pleasing. They play a key role when it comes to energy efficiency and sustainable development.

A curtain wall is a type of exterior cladding, usually in glass and aluminum, which offers maximum fenestration which is very efficient in terms of resistance to temperature, air, rain, condensation or any other weather.

At Epsylon, our curtain wall is prefabricated in our factory, and then installed on site. It’s made up of modules which are stacked, and which arrive at the site already ready with all the components, including the sealant. Once the module arrives on site, it is therefore ready to be installed quickly.

Otherwise, there is also the conventional curtain wall, which is used less on a large scale with us. This is manufactured but not assembled in the factory; and it will therefore be necessary to assemble it during installation on the site.

MAXIMIZING NATURAL LIGHT

One of the greatest advantages of curtain walls is that they maximize natural light within the entire building. Thanks to their large glass surfaces, they ensure interior spaces benefit from a ton of natural light which reduces the need for artificial lighting. The results speak for themselves: lower electricity bills and work and living spaces that are much more inviting. Furthermore, natural light has a positive effect on a person’s mood, their ability to focus, and their overall health and well-being.

LOWER ENERGY BILLS

Curtain walls do more than let in natural light, they also help regulate a building’s indoor temperature. State-of-the-art glazing technologies (low-emissivity, solar control, double or triple glazing) retain heat inside during the winter and prevent overheating in the summer. That means lower energy bills which turn into long-term savings.

Some systems do even more, integrating features such as sunshades, blinds, and even smart sensors that adjust the brightness according to the time of day. In sum, a curtain wall is the perfect solution for anyone who cares about sustainable energy performance.

EPSYLON’S ENVIRONMENTALLY RESPONSIBLE APPROACH

Choosing a curtain wall means doing your part for the environment. That’s because the materials used (aluminum, glass, etc.) can be recycled a nearly endless number of times. Curtain walls are also manufactured and assembled in a manner that minimizes losses and maximizes the product’s life span.

At Epsylon, we believe that energy efficiency and design can go hand in hand. That’s why our curtain walls are built with comfort, efficiency, and elegance in mind. All while adhering to an environmentally friendly approach.

Simply put, choosing a curtain wall is synonymous with choosing a cost-efficient, sustainable solution that maximizes the power of natural light. The three foundations of an architecture that is truly responsible and inspiring. An architecture that breathes in harmony with its environment.
