Windows

At Duratherm, we believe windows are far more than just glass in a frame. They are essential to the identity of a space—inviting natural light, framing the outside world, and defining both interior and exterior aesthetics. Every Duratherm window is meticulously handcrafted to meet precise specifications, delivering the performance, durability, and beauty that discerning architects, designers, and clients demand.

Our windows are handcrafted from start to finish, with unwavering attention to detail. Available in all-wood, split-species, or wood with aluminum-clad exteriors, they are built to last—and to elevate the spaces they occupy. Whether your design calls for clean modern lines or traditional profiles, when you partner with Duratherm, we ensure your vision comes to life without compromise. We do not provide off-the-shelf solutions. Instead, we collaborate closely with you to understand your goals, and then create a window system that enhances your vision rather than limiting it.

We offer a wide range of commercial glazing options tailored to meet your project’s unique needs—whether that means increased thermal efficiency, privacy, low reflectivity, or anything in between. Every element is chosen with performance and design in mind.

Wood is at the heart of what we do. While our clad windows may have an aluminum exterior, they are wood at the core. This core is important and that is why we have thoughtfully selected wood species that are best suited for interior and exterior applications. These options provide a range of tones and textures—from the rich character of ribbon-sawn sapele to the soft, neutral hues of white oak and maple. Our split-species windows allow you to pair a durable exterior wood with an interior wood that aligns with your interior preferences.

Just as important as the materials, is the finish. We offer both traditional oil-based finishes and high-performance, environmentally friendly waterborne film-forming finishes that fully encapsulate and protect the wood while enriching its natural beauty. The clad option has four standard finishes, or you can specify a custom RAL color to align perfectly with your exterior palette. With the wide array of options, tone, sheen, durability, and maintenance are all considered—so you can select a finish that fits your needs and your style.

Beyond the essential glazing and gasketing, we offer customizable profiles to align with your design intent. Whether your project calls for sleek contemporary edges or timeless traditional detailing, we will match the architectural characteristic desired.

As you consider Duratherm for your next window project, remember… we are not just a window manufacturer—we’re a design partner.

From material selection and finish options to custom design and attentive collaboration, we are here to help bring your vision to life with exceptional craftsmanship and performance you can count on.
