CRL-Sash Mill Universal Storm Window Frame
The CRL-Sash Mill Universal Storm Window Frame is a popular retrofit solution designed to replace or augment existing sash systems. It offers a no-adhesive installation approach, which simplifies retrofits on various window profiles. The system is marketed as sturdier than vinyl options and outperforming magnetic alternatives, making it suitable for long-term performance. The 12 ft length accommodates typical sash spans, enabling fewer joints and a cleaner installation when upgrading multiple windows on a single project.
CRL-Sash White Universal Storm Window Frame
This white-framed version emphasizes a clean, low-profile aesthetic while delivering the same retrofit benefits as the other CRL sash frames. With its claimed sturdiness and adhesive-free panel retention, it supports both glass and acrylic inserts. The 12 ft length minimizes field cuts and seam points, helping maintain thermal and wind resistance across multiple windows in a single project. The white finish also blends with many home exterior styles, reducing the need for repainting choices when installed in older homes.
CRL-Sash Bronze Universal Storm Window Frame
The bronze variant offers a distinct finishing option for exterior styling while maintaining the same core retrofit features: no adhesive required to hold panels and a focus on durability. It’s positioned as a robust alternative to magnetic or vinyl storm frames, suitable for retrofits where long-term stability and weather resistance are priorities. Like its white and mill counterparts, it supports glass or acrylic panels up to 1/8 inch thick and is designed for 12 ft spans, reducing the need for additional joining pieces on larger windows.
Gordon Glass Universal Retrofit Storm Window Frame
The Gordon Glass frame, branded by TechnologyLK, emphasizes customization with lengths tailored to single or double-strength glass and up to 1/8 inch thickness. It includes pre-installed vinyl gaskets to secure panels without adhesive, reducing installation complexity and potential panel movement. The option to create custom lengths makes it suitable for varied window sizes, including irregular openings where standard 12 ft frames would waste material. This frame aligns with retrofit projects seeking a balance between performance and tailored fit.
CRL White Standard Storm Window Frame
This CRL white standard frame is designed for adhesive-bonded installation and surface mounting. It provides a straightforward retrofit option for projects where an adhesive bond is acceptable or preferred due to window style or historical accuracy. The white color complements lighter exterior tones and aligns with CRL’s broader storm window family, offering a familiar mounting method for installers and homeowners alike. The 12 ft length facilitates efficient installation across typical multi-window runs.
Buying Guide
- Materials and finishes: Choose a frame finish that complements your exterior design (white, bronze, or custom tones). Consider long-term resistance to corrosion and weathering based on your climate.
- Panel compatibility: Verify that the frame accepts glass or acrylic panels up to 1/8 inch thick. Confirm whether pre-installed gaskets are included or if separate sealing is required.
- Adhesive requirements: Non-adhesive systems simplify removal and reinstallation, but ensure the chosen frame provides reliable panel retention. Adhesive-bonded frames may offer a tighter seal in some scenarios.
- Length and fit: Most frames are offered in 12 ft lengths to cover standard sash spans, reducing field cutting. For unusual openings, consider customizable length options where available.
- Installation approach: Some frames are designed for surface mounting, while others rely on existing sash channels. Assess whether you need a retrofit that minimizes changes to the existing window frame.
- Durability and warranty: Look for frames marketed as sturdier than vinyl or magnetic options. Check any included hardware, such as gaskets, for resilience and ease of maintenance.
- Cladding and aesthetics: For visible exterior frames, finish options and color matching can impact curb appeal and property value, especially on historic homes or heritage projects.
- Vendor support: Prefer brands with clear installation guides and customer support to assist with sizing, cutting, and gasket selection.
