To help you accomplish a successful installation of your new Windows and Doors, Glo European Windows offers on and off site technical assistance through our Installation Support Program. This program is an optional service provided at additional cost over and above the cost of the window package, which will be of great benefit to anybody who is planning on installing our windows and is not familiar with the European style window and door.



Our Installation Support Program will provide you with the following important step-by-step instruction:

  • Proper waterproofing or flashing techniques for preparing rough openings.
  • Attaching the windows and/or doors securely to the building structure while maintaining level, plumb, and square window and door frames.
  • Creating proper airtight connections between the interior of the window frame and the airtight layer of the building.
  • Applying appropriate insulation between the window and/or door and the rough opening.

Glo European Windows are available in three different attachment method systems: Screw System, Clip System, or an integrated Nail Flange System. Rough opening preparation recommendations will vary depending upon the system selected.

This service includes a consultative phone call prior to the day of installation to discuss the selected method of install and review the installation details. At this time, our technician will also recommend the required manpower and equipment to complete a safe and efficient install.

Window and door Install details for many common wall types are available from Glo European Windows. If install details for your project have been provided by your architect or contractor, Glo European Windows will require submission of these details for approval prior to installation.
