INTUS means 'Within' or 'Inside' in Latin

INTUS creates high performing windows and doors that conserve energy, increase thermal performance, and reduce noise. By balancing superb energy efficiency, affordability, and versatility, INTUS is making sustainable building attainable for any type of commercial project in the U.S.

The source of nearly 48% of the world’s greenhouse gas emissions are from buildings; windows and doors are key to dramatically increasing the energy efficiency of buildings and decreasing wasted energy. INTUS is committed to providing innovative solutions whether for a modern PHIUS certified multi-family buildinga luxury Marriott Moxy Hotel, or Senior Residence in NY. Through our customizable solutions it is now possible to balance costs, long-term performance, and secure savings on the ever- rising cost of energy.

The Team

The INTUS team originates from over 16 nations with the majority being bilingual or trilingual. Our team is made up of engineers, drafters, thermal analysts, project coordinators, estimators, technicians, business developers, and supporting staff in passive house and sustainable building consulting, accounting, marketing, graphic design, IT, administration, human resources, and more. We use our diversity to crush the box, innovate, and improve to provide the highest level of service to our clients — our core focus.

Offices Covering the Northeast and Mid-Atlantic

We are headquartered right outside Washington, D.C. (the world’s first LEED Platinum city) in Fairfax, Virginia. Through our regional offices in New York City, Boston, Chicago, Philadelphia, and D.C., and our National Accounts department, we are proud to service the entire United States.

INTUS Principles

Our philosophy started with conservation. We believe we must first eliminate waste to improve our planet, our communities, our buildings, our lives. By decreasing the carbon output of a building, sustainability automatically increases. This equates to buildings that perform better, last longer, are more enjoyed, and are better for the planet — our home. On the parallel, funds previously wasted on unnecessary energy bills can be used elsewhere — to increase a hotel’s profit margins, a school’s educational budget, or a multi family building’s occupancy rate.


To create modern, light-filled energy efficient buildings, innovation is imperative. INTUS is dedicated to constant innovation which requires flexibility, adaptability, and strict standards. By being at the forefront of energy efficient building standards since our inception we continue to be a step ahead and the top choice for Passive HouseLEEDNet-Zero, green buildings, and the environmentally focused builder.

To support humans on this planet, sustainability is fundamental. Buildings are currently one of the most wasteful sectors on the planet, but INTUS is proud to be reversing this through sustainable building. We achieve this by providing incredible energy efficient fenestration designs, recycling polymer in our manufacturing process, and providing affordable, practical, diverse solutions. Furthermore, we prioritize continuous education internally, and externally with those in the building and energy industries to ensure the best solutions are not only invented but implemented.

Why Polymer Windows?

Polymer window and door assemblies perform 2-3 times better than aluminum windows, with up to a 40% savings, while also reducing sound and conserving energy. Moreover, buildings are the source of nearly 48% of the world’s greenhouse gas emissions; windows and doors are key to dramatically increasing the energy efficiency of buildings, and decreasing wasted energy.

INTUS’ customizable polymer solutions balance affordability, long-term performance, and secure savings on the ever-rising cost of energy. Creating an energy efficient building is not just the eco-friendly way, but the best approach to ensure a high return on investment.
