Yes! We have several certified AIA presentations. Learn more about the current presentations we offer and to schedule a lunch and learn here.
uPVC is PVC with no plasticizers, or unplasticized polyvinyl chloride – sometimes known as rigid PVC or Polymer in the U.S.
uPVC is made with a special formulation in which modifiers and lead-free stabilizers are added to PVC so it becomes rigid, making it suitable for window frames
uPVC is a rigid, chemically resistant form of PVC used for pipework, window frames, and other structures
Not all polymer or uPVC is the same. INTUS takes steps to ensure our polymer is free of toxins like lead, BPA, and phthalates. Plus, we offset the carbon from our buildings through our One Window, One Tree program.
Polymer (uPVC) windows, such as those in the INTUS Supera series, deliver a powerful combination of energy efficiency, cost-effectiveness, and long-term durability. They are ideal for multifamily, institutional, and commercial projects where sustainability and ROI are critical.
Key benefits include:
Superior thermal insulation – low U-values reduce HVAC loads and energy bills.
Excellent air and water tightness – supports Passive House and energy code compliance.
Cost-effective production and installation – deliver long-term savings for developers.
Low maintenance - no painting, warping, or corrosion over time.
Strong acoustic insulation – perfect for high-noise urban environments.
Environmentally responsible – 100% recyclable and free of lead or heavy metals.
Yes! Polymer is a self-extinguishing material. It has been validated through ASTM E84 testing to be used in mid-rise and high-rise applications.
Yes! The polymer that INTUS uses can be recycled up to 7 times, and the steel and glazing components can also be recycled.
No! Our products do not off-gas or contain any of these contaminants. We have a lead-free certificate available upon request and our products are eligible for the following LEED points within the Building Product Disclosure & Optimization category:

Material Ingredients (2 points)
In total, INTUS Windows can gain a project 44 LEED point!
Aluminum windows are known for their strength, slim profiles, and design versatility, making them the go-to choice for commercial, multifamily, and high-rise applications.
Key benefits include:
Slim, modern frame profiles allow larger glazing areas and more natural light.
High structural strength - ideal for mid- and high-rise buildings, commercial loads, and large openings.
Durable and low maintenance - resistant to rust, warping, and corrosion in all climates.
Thermally broken for energy efficiency - meets or exceeds energy code requirements when combined with high-performance glazing.
Recyclable and sustainable - aluminum is 100% recyclable with low embodied carbon when reused.
Yes, aluminum is 100% recyclable - and it can be recycled infinitely without losing quality. Using recycled aluminum requires only 5% of the energy needed to produce new aluminum from raw materials, making it an excellent choice for sustainable construction. INTUS Windows’ XLine aluminum products are manufactured with this in mind, contributing to LEED® credits, lowering embodied carbon, and aligning with circular economy principles.
Aluminum windows achieve energy efficiency through thermally broken frame technology insulating barrier, typically made of polyamide, that separates the interior and exterior aluminum profiles. This design minimizes thermal bridging, reducing heat loss in winter and heat gain in summer.
INTUS aluminum windows enhance this performance with high-performance glazing, warm-edge spacers, and airtight construction. Together, these elements provide outstanding thermal insulation, low U-values, and excellent acoustic performance, making them ideal for energy-efficient buildings in urban, high-traffic, or noise-sensitive environments.
iWALL is a modular façade system where each façade panel is manufactured, glazed, and insulated in a controlled factory environment. The assembled elements arrive at the construction site sealed and ready for installation, significantly reducing labor costs, delays, and quality issues compared to traditional timber façades.
iWALL delivers gains in:
Reduced Labor Costs. Fewer installers, less equipment, and shorter timelines.
Quality Control. Manufactured for unmatched precision, consistency, and quality.
Urban-Friendly. Faster installations mean less noise, dust, and traffic.
Overlapping Timelines. Install façade units before upper floors are built - saving months on the schedule.
Construction Cost Control. Less time, fewer trades, fewer unknowns, better budget predictability.
Fast Installation. Pre-assembled units cut on-site work, speed timelines, and boost revenue with quicker delivery.
Sustainability Built-In. Up to 75% recycled aluminum- eco-smart and high-performing.
These benefits make iWALL ideal for large-scale, time-sensitive projects.
Yes. iWALL offers a wide range of finishes (e.g., Anthracite Gray, Warm Stone), flexible panel dimensions, and custom glazing configurations - allowing architects to meet aesthetic and performance goals without compromising speed or precision.
Absolutely. iWALL features thermally broken frames and high-performance glazing to support low U-values and minimize HVAC demands. Panels can include up to 75% recycled aluminum, aligning with LEED, Passive House, and Net-Zero certification requirements.
