What a Live Burn Test Taught Us
About Glass Specification
In a live burn test, a Viking DK22 with fully tempered triple glazing was compared with a double-pane annealed vinyl window. The results highlighted why glass specification deserves closer attention.
One real-world test, not a controlled scientific study.

"Axel has been an absolute joy to work with over the years, and the products he reps (most notably Viking windows & doors) are superior. He has been a valuable team member on every project we've worked on together, and it's clear he cares deeply about getting things right. Axel continually brings his tremendous knowledge base and positivity to all interactions with the team; I know clients and contractors appreciate his insights."

"Our prefab company recommended we reach out to Axel and we are so glad that we did. It was apparent from our first conversation that he was immensely knowledgeable and had our best interests at heart. I cannot fathom navigating the complexities of selecting and ordering windows without his guidance. I only wish I had “an Axel” for all the other aspects of our home build! We knew from the start that we wanted the best windows we could afford. Our Viking windows beat out two other companies - not just in performance, but also in price. We are so excited for our new windows and doors and look forward to living with them for the rest of our lives!”

"Axel Brodermann has been outstanding to work with. He delivers what he promises, keeps you informed along the way, helps you make the right decisions for you, and stays on top of things all the way through completion and beyond. The products he works with are top of the line – in my case I ordered Viking windows and I could not be more satisfied with the result, which in no small part was thanks to Axel for making the recommendation and supporting the whole process."

OUR PROJECT WORK
Common Questions About European Windows & Doors
What type of projects does E Windowtastic support?
E Windowtastic supports high-performance homes, Passive House projects, design-build work, ADUs, remodels, and residential projects that require durable European window and door systems.
Do you offer free quotes?
Yes. You can request a project quote by sharing your project type, location, window or door requirements, and any available plans or measurements.
Are your windows and doors custom made?
Yes. E Windowtastic offers custom-fit European window and door systems.
Do you have a showroom I can visit?
Yes. E Windowtastic has a showroom in Denver where most products can be viewed by appointment.
Which product system is right for my project?
It depends on your project goals, opening sizes, material preference, and performance requirements. Viking, AluProf, and AluPlast each serve different use cases, so the best option is usually confirmed after reviewing the project details.
Do you work with architects and builders?
Yes. E Windowtastic supports architects, builders, developers, energy consultants and homeowners who need guidance on European window and door systems, product specifications, and project fit.
Do you support Passive House projects?
Yes. E Windowtastic works with systems designed for high-performance and Passive House level goals, including strong insulation, airtightness, and energy efficiency.
Is oak stronger than laminated pine for window frames?
Oak has greater raw density and screw retention. Viking’s laminated pine, however, is engineered for dimensional stability, resistance to warping, and supporting the weight of double- or triple-glazed units. Oak is primarily chosen for its distinctive grain and premium appearance, while laminated pine is the practical choice when engineered stability is the priority.
Are all systems suitable for large openings?
No. Some systems are better suited for large glass openings, while others are designed for standard or smaller residential openings. E Windowtastic helps guide you toward the system that fits your project.

Whether you’re planning a high-performance home, Passive House build, remodel, ADU, or design-led project, E Windowtastic can help you find the European window and door system that fits your goals, your budget, and your build.
