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.

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.
