Fenster replica sashes for hail damage.

In the case of hail damage, the exterior skin, or "cladding" of a window sash cannot be replaced. With many brands obsolete, the original components are not available or restricted. Fenster replica sashes are an after-market sash replication of many major brands guaranteed to exceed like, kind, and quality requirements of the insurance industry.


Fenster replica sashes are NOT a universal, one size fits all replacement sash. Each model is precisely engineered to resemble in appearance, and function exactly as the original brand product did using today’s technology and available components.


Fenster replica sashes are made of solid, eastern white pine treated with woodlife 111, the industry standard for millwork grade wood preservatives. Fenster replica sashes aluminum cladding are industry standard .019 gauge roll formed aluminum to match the existing windows. In some cases, non-wood components proprietary to the original manufacturer are not available, specifically exterior side vinyl glazing beads and rubber glazing boots, causing minor appearance differences that will not affect the performance or function of the window.


Fenster replica sashes come standard with lowE glass that meets 2016 energy star 2.0 performance ratings. In most cases, Fenster replica sashes will upgrade the existing window’s quality and energy performance. lowE w/ Argon, safety tempered glass, internal grills, surface applied grills and wood grill inserts are available options. Fenster replica sashes are available in six common standard exterior colors with perimeter weather-stripping applied where applicable.


From a performance, function, and quality perspective, there are no limitations to Fenster replica sashes when engineered for the proper application. However, it is notable that existing removable interior wood grills will NOT fit in new Fenster replacement sashes. Quiksash double hung kits are designed to fit a window with compression style jambliners ONLY. Our double hung kits will NOT work with a static, easy-tilt system that has sliding sash locks on the sash tops.


A pre-finished interior option is available to make installation even more convenient on larger volume, whole house projects. Finished product can be shipped prefinished ready for final install eliminating the need for additional painting contractors and reduced service issues after installation. A minimum order of 20 units is required for pre-finishing services.

Full 10 year warranty.

No fineprint guarantee.

Casement profiles are re-engineered to accept Fenster cladding shapes while maintaining the fit and function of the original design. Depending on the original specifications, our 1-1/2", 1-3/4" or 2" wide cladding is applied to match the original face width as closely as possible. This design change does affect the glass sizing, but does not affect the over-all net sash size hence why we do not accept glass sizes for measurements.
