Glo European Windows & Doors

Mark and the team at Glo have exceeded our marks when it comes to high quality, passive house high performance windows. Their product stands for itself with highly durable and functional hardware, coupled with extremely good U-values. The concealed hardware and modern frames have shown beautifully in our homes, and will continue to work with.

As a window professional, we were very pleased with our experience with Glo. the before the sale experience, communication before delivery, and on site technical support they provided was second to none. Mark was excellent with our design challenges, Russ provided very detailed technical support and complete shop drawings, and Tom was a key part of the onsite delivery and construction of our very large window units. The specialty doors are incredibly easy to assemble. I would suggest taking their advice on using lift and slide doors as they are effortless to operate. All said and done, the product is beautiful and should be considered for any higher end residential or commercial projects.

We are architects who design high performance passivhaus architecture exclusively, and work with many excellent, passionate members of the Passive House community. Within this group, Energetechs stands out due to their knowledge, service, and commitment to providing the best possible outcomes for customers... which is why they took the initiative to undertake the GLO project to begin with. Put your trust in these guys.

Energetechs has been a trusted partner for us in numerous high performance and off grid projects. They are prompt, professional and do high quality work. When you HVAC, insulation or windows need to be just right in order to make your project work they are definitely the people to call.

NDA has been fortunate to work with Energetechs and Glo for a few years now. They always provide excellent product & support, and are great team members! A newly completed home by NDA features patio doors and front entry doors supplied & installed by Glo. They provide both great energy efficiency and aesthetic for the residents. I will continue to work with Glo and highly recommend them!

Gaddy Construction has been working with Mark and Russ since 2013 and we have been very impressed by their professionalism and experience. The products and services offered are unmatched and we would highly recommend them for your next project.
