Therma Web™ · Patent pending
A different wayto build asteel window
The weakest part of many thermally broken steel windows isn't the steel. It's the poured or crimped polyamide plastic holding the two halves of the steel frame together. The plastic reduces heat transfer, but it also forms part of the structural connection. Under extreme heat or stress, that connection can weaken, potentially causing the entire window to fail. So we created Therma Web™, Revyn's patent-pending technology that combines three engineering innovations.
How it works
Three innovationsin one frame
01
A welded stainless steel truss
We precision-cut American 316 stainless steel sections and join them with strategically welded internal webs. Together they form a continuous H-shaped truss that spreads structural loads through the frame. It resists twisting, warping and movement, even under demanding conditions.
02
A next-generation thermal break
It reduces heat transfer without the plastic structural connectors used in other thermally broken steel windows. The truss provides the strength. The thermal break provides the insulation. Neither has to do the other's job.
03
Five adaptable performance cores
Fire, thermal, hurricane, sound and ballistic. The same truss and thermal break accept different cores, selected or combined to suit the conditions each building will face.
Side by side
Conventional steelversus Therma Web™
| Conventional thermally broken steel | Revyn Therma Web™ | |
|---|---|---|
| Structural connection | Two halves of a steel frame joined by poured or crimped polyamide plastic, which also forms part of the structure | A welded 316 stainless steel truss that provides its own strength |
| Under extreme heat | The plastic connection can weaken, potentially causing the window to fail | Strength comes from the steel, not from a plastic connector |
| How frames are made | Rolled or extruded profiles with multiple manufacturing and assembly steps | Laser-cut from stainless steel sheets, joined with internal structural welds |
| Gaskets | Often adhesive-backed, which can loosen or fall out | Designed to eliminate the common use of adhesive-backed gaskets |
| Finish | Commonly liquid paint, as the polyamide plastic thermal breaks soften and blister when heated in a powder coat oven | High-temperature powder coat, C4 corrosion rating standard, C5 on request |
| Sizes and configurations | Often a different system for different sizes | Parametric design adapts one frame structure across a wide range of sizes |

Are we playing with fire by overlooking windows and doors?
Written by the team behind Revyn, it explains what really happens when fire reaches a window, what today's tests do and don't tell you, and the questions to ask before you specify. Including the ones to ask us.

Performance cores
One technologyFive cores
A home in wildfire country faces different conditions from one in a hurricane zone, a noisy city or a high-security building. Traditionally, that meant specifying entirely different window systems. Therma Web™ meets them without reinventing the frame.
Fire
Engineered to resist extreme heat and prolonged exposure to open flame in wildfire-prone areas.
Thermal
Reduces heat loss in winter and heat gain in summer, for comfort in extreme climates.
Hurricane
Designed to withstand high winds, impact and severe coastal conditions.
Sound
Improves acoustic insulation against traffic, aircraft and other unwanted noise.
Ballistic
Enhanced protection for buildings with high-security requirements.
Our initial focus is wildfire protection and energy efficiency. Other configurations require their own engineering, testing and certification.
Made smarter
Cut fromstainless sheets
Conventional steel windows are often assembled from separate profiles, with exposed corner welds and joints that can become points of corrosion, paint failure or weakness. We cut our frames from stainless steel sheets and join them with internal structural welds.
- Greater precision: tolerances within a fraction of a millimeter, so windows fit with less shimming, trimming and callbacks
- Less waste: cutting software gets the most from every sheet, and clean offcuts are recycled or repurposed
- Fewer steps: fewer components and assembly operations than conventional thermally broken steel windows
- Design flexibility: one process produces a wide range of sizes, shapes and configurations
Therma Web™ questions
Askedand answered
What is Therma Web™?
Revyn's patent-pending technology behind every Revyn window and door. It combines a welded 316 stainless steel truss, a next-generation thermal break and five adaptable performance cores.
Why does it matter that there are no plastic structural connectors?
In many thermally broken steel windows, poured or crimped polyamide plastic holds the two halves of the steel frame together. The plastic reduces heat transfer, but it also forms part of the structural connection. Under extreme heat or stress, that connection can weaken, potentially causing the entire window to fail. In Therma Web™, the welded stainless steel truss carries the structure, so the thermal break only has to insulate.
Can Revyn frames be powder-coated?
Yes, because Therma Web™ doesn't rely on a conventional polyamide thermal break. Our stainless steel frames receive a full powder coat finish encapsulating the entire frame and sash before assembly. The powder is baked at high temperature. Our finish carries a C4 corrosion rating, with C5 available on request.
Is Therma Web™ used in both series?
Yes. The Extreme Climate Series and the Legacy Series share the same Therma Web™ technology and performance cores. The Extreme Climate Series comes in a focused range of standard sizes. With the Legacy Series, architects can choose the level of design flexibility their project requires.
