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!

New York City’s building regulations are continuing to push the industry toward higher-performing, lower-emission buildings—and Local Law 97 is part of that shift.

For architects and developers, this means building performance can no longer be treated as a late-stage consideration. Decisions around the building envelope, glazing, and airtightness increasingly impact long-term energy efficiency, operational costs, and compliance readiness.

As standards evolve, project teams are under greater pressure to:
• Reduce operational energy demand
• Improve envelope performance
• Future-proof building assets
• Deliver measurable performance outcomes

At INTUS, we support architects and developers with high-performance window systems engineered for modern building envelopes—helping teams integrate performance into the design process with greater precision and confidence.

Did you know the built environment accounts for roughly 40% of global CO₂ emissions?

For architects and sustainability consultants, improving building performance starts with the envelope—and windows play a much bigger role than many teams realize.

In our latest article, we explore how high-performance window systems support lower operational energy use, better airtightness, and more efficient building design.

🚫 Most NYC compliance issues don’t start at inspection.

They start much earlier — during specification, documentation, and coordination.

Here are 3 of the most common mistakes that delay projects:

1️⃣ Wrong window performance specs
Incorrect U-values, air leakage issues, and non-compliant glazing selections can quickly create approval problems.

2️⃣ Missing documentation
No testing reports. Missing certifications. Incomplete shop drawings.
If the paperwork isn’t complete, the system isn’t compliant.

3️⃣ Poor envelope coordination
Window-to-wall transitions, thermal bridging risks, and disconnected teams often create costly performance gaps.

The good news? Most of these problems are preventable with earlier coordination and the right performance strategy.

High-performance buildings demand more from window systems than ever before.

For architects, success today means balancing ambitious façade design with thermal performance, airtightness, acoustic comfort, constructability, and evolving energy standards — all within increasingly complex building envelopes.

At INTUS, engineering is not treated as a product feature. It’s part of how we help project teams reduce complexity and move from concept to construction with greater clarity and confidence.

As performance expectations continue to rise, precision engineering and collaborative problem-solving become essential to successful project delivery.

Unitized façade systems continue shaping the way teams approach performance, coordination, and construction timelines on modern projects.

We put together a few practical considerations architects should keep in mind when evaluating unitized curtain wall systems — from installation sequencing to early-stage coordination and performance planning.

What challenges are teams seeing most often today when coordinating façade systems across disciplines?

Retrofitting an existing building doesn’t mean sacrificing performance.

With the right high-performance window system, retrofit projects can significantly improve thermal efficiency, airtightness, occupant comfort, and long-term energy savings — approaching the standards typically associated with new construction.

The right upgrade can completely transform how a building performs.

Most architects don’t need another product presentation.

They need clearer answers to real project challenges.

The best Lunch & Learns help teams better understand:
• Building envelope performance
• Thermal bridging risks
• Code compliance requirements
• Installation coordination
• Long-term energy efficiency

Because decisions made early in design often determine how well a building performs later.

The most valuable conversations happen when education comes before promotion.

When comparing polymer and aluminum windows, performance depends on far more than appearance.

uPVC systems are known for strong thermal insulation, lower heat transfer, and excellent long-term energy efficiency — making them a common choice for high-performance residential and Passive House projects.

Aluminum systems offer slim sightlines, structural strength, and the ability to support larger openings, which is why they’re often used in commercial and contemporary architectural applications. However, thermal breaks are critical to improving their energy performance.

The right material depends on the specific goals of the project:
• Energy efficiency
• Structural requirements
• Design aesthetics
• Building scale
• Long-term performance expectations

There’s no single “best” option — only the right fit for the application.

"What causes more project problems: the façade design itself — or choosing the wrong system for how the building actually needs to perform?

The decision between stick-built and unitized façade systems impacts far more than aesthetics.

It can affect:
• Installation speed
• Site coordination
• Labor efficiency
• Construction sequencing
• Long-term performance

Stick-built systems can offer greater flexibility and easier field modifications — which can be critical on more customized or complex projects.

Unitized systems can help reduce installation time, improve quality control, and simplify on-site ex*****on — especially on larger-scale developments.

So what actually matters most?

The answer depends on the project priorities:
• Faster timelines
• More flexibility
• Better performance coordination
• Reduced construction risk
• Improved site efficiency

There’s no universal “best” façade system — only the best fit for the project constraints.

Windows can account for over one-third of a commercial building’s heat gain and loss—making them one of the most critical decisions in high-performance design.

That’s why polymer window systems are becoming a cornerstone of Passive House projects. With inherently low thermal conductivity and exceptional airtightness, they consistently outperform traditional materials in real-world performance.

Join Sam Kintzele (INTUS Windows) at the upcoming Passive House Accelerator event for a technical deep dive into:
• Why window selection defines your energy model
• Key performance advantages of polymer systems
• Latest developments in Passive House-certified solutions (Supera 74, 83 & Passive+)

Expect practical insights, real project experience, and yes—things might get a little geeky.

Choosing the right window system isn’t just about meeting performance targets—it’s about how the system integrates into the overall building design.

The Supera Series is developed for projects that demand both:
strong thermal performance and clean architectural detailing.

It’s particularly well suited for:
– Multi-family residential projects
– High-performance homes
– Commercial buildings with strict energy goals

What matters most is not just the product itself, but how it supports the broader façade strategy—balancing performance, flexibility, and design intent.

The takeaway:
Better window systems contribute to better buildings—when they align with the needs of the project.
