Quiksash 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. Quiksash is an after-market sash replication of many major brands guaranteed to exceed like, kind, and quality requirements of the insurance industry.


Quiksash is 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. All Quiksash models are designed to resemble the original window as closely as possible using today’s technology and available components.


Quiksash products are made of solid, eastern white pine treated with woodlife 111, the industry standard for millwork grade wood preservatives. Quiksash aluminum cladding is 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 causing minor appearance differences that will not affect the performance or function of the window.


Quiksash comes standard with lowE w/ argon glass that meets 2016 energy star performance ratings. In most cases, Quiksash will upgrade the existing window’s quality and energy performance. High performance lowE, internal grills and safety tempered glass are available. Quiksash is available in three industry standard exterior colors, with dozens of custom color match options. Synthetic cPVC bottom sash rails are available as a premium upgrade for extended life and added protection from wood rot.


From a performance, function, and quality perspective, there are no limitations to Quiksash when engineered for the proper application. However, it is notable that removable interior wood grills will NOT fit in new Quiksash replacement sashes. Grills between the glass must be substituted for removable wood grills, or wood grills deleted. Fenster does not offer re-sizing of existing wood grills.


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. Pre-finishing stationary sash prior to install is recommended to guarantee all edges are sealed to reduce water absorption into the wood. Pre-finishing is required by Fenster at production, or other painting contractor prior to installation when ReWindow is hired to perform the install.
