Fortress Installation Systems creates a concealed moisture management chamber that redirects water away from the rough opening—eliminating weak points at the corners. It integrates effortlessly with flashing tape and spray foam, forming a complete, code-compliant seal. Designed to work with all major window brands, including Pella, Fortress ensures long-term protection with minimal effort.

The Fortress Installation System once installed paired with flashing membrane and expandable foam allows for a window, door or PTAC unit to integrate with a buildings envelope system but also, operate independently from the walls assembly, its building envelope-based design principles is what determines its moisture management surety and protects the wall assembly.
Yes, the Fortress system is fully compatible with all window and door installations in commercial and residential projects.
Yes, the Fortress system is fully reviewed for the LEED Program with all window and door installations in commercial and residential projects, remarkably by only using Fortress on your LEED Project it obtains the programs minimum requirements by itself offering over 41 points.
The Fortress Corner Guard eliminates the need for the installation of multiple over lapping layers of sill flashing membrane as required to achieve a moisture tight corner.
Simply fit the Corner Guard into the bottom sill corners of the rough opening and staple or nail into position and the corner is moisture tight.
The Corner Guard simplifies and speeds up the installation of the back dam and support shims and requires less flashing membrane.
No,the Fortress Corner Guard eliminates the need for accurately cutting and fitting of the flashing membranes.
The sill flashing membrane can be cut ½” to 1” short of the sill corner and will still maintain +4” of bonding surface for the sill flashing to bond down to the top side of the Corner Guard for full bond adhesion.
At the jamb, the jamb flashing can be cut ½” to 1” short and still maintain a 2” outwards shingled overlap onto the Corner Guard. The fact that the flashing membranes do not need to be accurately cut and carefully fit is easier and faster for the installer and speeds up the installation
A primer-less flashing membrane can be used with Fortress. If primer-less flashing membranes are used, primer is eliminated from the installation speeding up the installation time required.
The Fortress Installation Systems warranty requires using/applying FORTRESS SUPER SEAL low expansion spray foam insulation in the perimeter cavity for all fenestration installations with their products. As the bottom sill flange is not sealed to allow for drainage of the rough opening, air infiltration or leakage can occur behind the sill flange. Spray foam seals against air infiltration or air leakage and provides additional strength around a window or doors frame.
At Fortress we have invested a significant amount of time and resources consulting with building officials, building consultants, window manufacturers, installers, and analyzing fenestration installation failures and related issues throughout the industry. Based our findings, the most common building envelope failures are generally located around penetration through the weather resistive barrier:
– windows
– doors
– skylights
– deck and/or roof connections
– Packaged Terminal Air Conditioners (PTAC) units
Fortress is solution for 3 of the 5 most common building envelope failures or 75% of all building envelope failures.
Yes, the Fortress system is fully warrantied with registration for the life of the building (50years) with our ‘Products and Completions’ Insurance policy/warranty at $1M per occurrence.
Fortress is not compatible with skylights. But Fortress either meets or exceeds the requirements of ASTM E2112-19C. Refer to our document Fortress Technical Review of Fortress Installation System’s Fenestration Rough Opening Details.
PTAC installation failures are as common as window installation failures, if not more common on a percentage basis. These result in costly repairs as well. Fortress can be used for any PTAC installation rough opening moisture protection installation for in-wall Packaged Terminal Air Conditioners (PTAC) units.
