INTUS Windows

INTUS Windows INTUS unites extreme energy efficiency with affordability and versatility. INTUS means ‘within’ or ‘inside’ in Latin.

We create high performing windows and doors that conserve energy, increase thermal performance, and reduce noise. Since 2010, INTUS Windows has been a pioneer in manufacturing and distributing extremely energy efficient windows and doors in the United States. Our windows have been essential components in the U.S.’ first Passive House Certified church, the first LEED-Platinum mixed-use residential/

retail building, Maine’s first Passive House school, NY’s largest Passive House co-housing project, and dozens of LEED, Passive House, and Energy Star Certified building projects. From our products to our team, we are innovative and diverse. The INTUS team is made up of over 14 nationalities with the majority being bilingual. Our team includes engineers, drafters, project coordinators, estimators, technicians, business developers, and supporting staff in consulting, accounting, marketing, graphic design, administration, and more, to ensure that our clients receive the service they need and deserve. Our main office is right outside Washington, D.C. in Fairfax, V.A., and we service the entire United States, with offices in New York City, Boston, Philadelphia, and Baltimore. By 2036 we aim to offset carbon emissions enough to recover the absorption rate of 5 billion trees through our energy efficient products!

We're excited to announce our participation in Greenbuild 2026.

From October 20–23, we’ll be joining architects, developers, sustainability leaders, and green building professionals at the Javits Center in New York to discuss high-performance building solutions and the future of more resilient, efficient buildings.

For teams focused on energy performance, building envelope strategy, and long-term project value, Greenbuild is a valuable opportunity to connect and explore what’s next.

As we enter the start of the Hurricane season it’s a good time to reflect on the importance design plays in being prepared.

For architects and developers, early decisions around wind resistance, water performance, structural requirements, and verified testing data can affect how well the building envelope is prepared for severe weather conditions.

The goal is not to react once storm season is already underway. It is to understand performance requirements early enough to make better decisions during design, documentation, and procurement.

For developers, envelope performance is not just a design detail.

It can influence operating demand, occupant comfort, marketability, durability, and long-term asset value.

Windows and façade systems are a major part of that equation. When thermal performance, airtightness, acoustic control, and installation coordination are addressed early, projects are better positioned to perform after occupancy — not just at handoff.

Better envelope decisions can support stronger buildings, fewer performance issues, and more resilient long-term investments.

When project teams think about acoustic performance, glass is often the first thing they focus on.

But glass is only one part of the system.

Frames, seals, airtightness, and window-to-wall installation details can all affect how sound moves through the building envelope. For architects and developers working on urban residential, hospitality, education, or mixed-use projects, that distinction matters.

A stronger acoustic strategy starts by looking at the full assembly — not just the glass package.

July 26 marks the 36th anniversary of the Americans with Disabilities Act.

For architects, it is a reminder that accessible design should be integrated from the earliest stages of a project — not treated as a late-stage compliance item.

Entrances are one of the most important places where inclusive design becomes visible. Clear access, coordinated thresholds, durable door systems, and reliable operation all help create spaces that are easier and more comfortable for more people to use.

At INTUS, we support project teams with entrance and door options that help align accessibility, building performance, and long-term usability. ❤️

Window performance is not determined by glass alone.

For developers and sustainability consultants, understanding the full window system matters because each component can affect energy efficiency, airtightness, durability, comfort, and long-term building performance.

Glass packages, frames, spacers, seals, hardware, and installation details all play a role in how a building performs after construction — not just how it looks on paper.

In our latest article, we break down how window components work together and why early coordination can help project teams make better performance decisions.

When temperatures rise, occupant comfort depends on more than air conditioning.

Window performance directly impacts solar heat gain, cooling loads, and how consistently indoor spaces stay comfortable throughout the day.

For architects and developers, designing for summer comfort means thinking beyond aesthetics and considering how the building envelope performs under real-world conditions.

In our latest article, we explore the role window performance plays in creating more comfortable, efficient buildings during peak summer conditions.

High-performance buildings don’t fail only because of poor products. They often fail because installation quality doesn’t match the performance expectations of the system.

Small issues around sealing, tolerances, flashing, or window-to-wall transitions can create long-term problems that impact energy efficiency, moisture control, occupant comfort, and durability.

That’s why installation shouldn’t be treated as the final step of a project—it should be part of the performance strategy from the beginning.

At INTUS, our field support team works directly with project teams to help address installation challenges, answer technical questions, and support proper ex*****on in the field. Because achieving high performance requires more than the right system—it requires the right coordination throughout the project lifecycle.

When occupants complain about noise, the first assumption is often: ""We need better glass.""

But glass is only one part of the equation. In many cases, air leakage, poor detailing, or installation gaps can have a bigger impact on acoustic performance than the glazing specification itself.

That's why architects and developers are increasingly looking at acoustic comfort as an envelope design challenge—not just a window selection decision.

Urban projects are facing increasing pressure to improve occupant comfort—not just energy performance.

Noise from traffic, transit, and dense city environments can directly impact how people experience residential, hospitality, and mixed-use buildings.

That’s why acoustic performance is becoming a more important part of envelope design discussions early in the project lifecycle.

In our latest article, we explore how window system selection and envelope performance contribute to better acoustic comfort in urban buildings.
