Key Installation Considerations
Installation of Crystal windows and doors involves several critical steps that must be executed with care to ensure proper function and long-term performance. These include site preparation, product handling, framing, flashing, and final sealing.
1. Site Preparation
Before installation begins, the site must be prepared to ensure that the structure is ready to receive the new windows or doors. This includes verifying that the opening dimensions match the product specifications and that any existing framing or materials are in good condition. For new construction, Crystal recommends that windows and doors be installed during the early stages of the build to avoid damage and ensure seamless integration with the structure.
2. Product Handling
Crystal windows and doors are designed to be durable, but they must be handled with care to prevent damage. All products should be stored in a dry, level area with adequate support to avoid warping or distortion. Installers should also follow the manufacturer’s recommendations for lifting and positioning the units to prevent stress on the frames.
3. Framing and Support
Proper framing is crucial for ensuring the structural stability and performance of the window or door. Crystal windows and doors require a solid, level frame that is properly aligned with the opening. For vinyl and UPVC units, the manufacturer recommends using a continuous nailing fin or optional nailing fin to secure the frame to the wall structure. Aluminum products typically require a heavier-duty frame due to their larger size and weight.
The following are key dimensions and specifications for some of Crystal’s most commonly used window and door models:
| Product Line | Jamb Depth | Frame Type | Additional Features |
|---|---|---|---|
| Series 300 (Single-Hung) | 2-5/8” | Vinyl | Tilt-in bottom sash, continuous head and sill |
| Series 310 (Picture) | 2-5/8” | Vinyl | Fixed, factory-mulled, integral nailing fin |
| Series 235 (Casement) | 3-1/4” | Vinyl | Outswing, crank operator, multi-point locking |
| Series 1500 (Sliding Glass Door) | 4-5/8” | Vinyl | Adjustable steel tandem rollers, locking handle |
These specifications are based on Crystal’s official documentation and are critical for ensuring proper fit and function. Installers should always verify these details before beginning the installation process.
4. Flashing and Weatherproofing
To ensure long-term performance and prevent water intrusion, Crystal windows and doors must be properly flashed and sealed. The company recommends using a combination of weatherstripping, caulk, and flashing materials to create a watertight barrier between the window/door and the surrounding structure. All products are factory-fitted with double weatherstripping, but additional sealing may be required depending on the climate and local code requirements.
Flashing should be installed behind the window or door frame to direct water away from the opening. This is especially important in areas prone to heavy rain or high humidity. Crystal also recommends using a continuous nailing fin to provide additional support and a surface for attaching flashing material.
5. Adjustments and Final Checks
After the window or door is installed, it must be adjusted to ensure proper operation and alignment. This includes checking the sash for smooth movement, verifying that all locking mechanisms function correctly, and ensuring that the unit is level and plumb. For casement and sliding glass doors, the manufacturer recommends adjusting the rollers and hinges to ensure even weight distribution and prevent sagging over time.
Once adjustments are complete, a final inspection should be conducted to verify that all components are functioning as intended and that the unit is properly sealed against air and water infiltration. This is also an opportunity to train the end user or property manager on how to operate and maintain the window or door to extend its lifespan.
Installation Best Practices for Specific Products
Crystal offers a range of window and door models, each with unique installation requirements. The following sections provide detailed guidance for some of the most commonly used products.
Vinyl Replacement Windows
Vinyl replacement windows are designed for retrofitting existing openings and offer excellent energy efficiency and ease of installation. These windows can be installed using a nailing fin or by direct framing into the wall. The key to a successful installation is ensuring that the window is properly aligned with the opening and that all gaps are sealed with caulk or foam insulation.
Crystal recommends using a level and plumb to ensure the window is installed straight and that the sash opens and closes smoothly. For older homes with irregular openings, additional framing or shimming may be required to achieve a secure fit.
Aluminum Doors
Aluminum doors are ideal for commercial applications due to their strength, durability, and resistance to corrosion. These doors require a heavy-duty frame and precise installation to ensure proper operation and longevity. Crystal recommends using a door threshold to prevent water infiltration and provide a smooth transition between the interior and exterior.
For multi-story buildings, it is essential to use a thermal break in the door frame to prevent heat transfer and maintain energy efficiency. Installers should also follow local code requirements for door clearances, thresholds, and accessibility features.
UPVC/Passive Windows and Doors
Magnus UPVC/Passive windows and doors are engineered for maximum insulation and energy efficiency. These units feature a thick frame and multi-layered glazing to minimize heat loss and reduce energy consumption. During installation, it is important to maintain the integrity of the thermal barrier and ensure that the unit is properly sealed against air leaks.
Crystal recommends using a continuous nailing fin and flashing material to secure the frame and prevent water infiltration. For passive projects, it is also important to verify that the unit is installed at the correct angle to maximize solar gain and minimize thermal bridging.
Case Study: The Arboretum Development
To illustrate the importance of proper installation, consider the Arboretum development in Nashville, where Crystal supplied over 4,261 windows and doors. The project included a mix of vinyl and aluminum products, with the majority being Crystal Series 300 single-hung and fixed picture windows.
The Series 300 windows were installed using a continuous head and sill master frame, with a 2-5/8-inch depth and a tilt-in bottom sash. This design allowed for easy cleaning and maintenance while maintaining a high level of energy efficiency. The windows were rated R-PG25 with a U-value of 0.30, indicating strong thermal performance.
The project also included over 300 Series 235 vinyl casement windows, which feature a 3-1/4-inch jamb depth, double weatherstripping, and a crank operator. These windows were installed with multi-point locking to ensure security and weather resistance.
For patio access, the development used Crystal Series 1500 vinyl sliding glass doors. These doors have a 4-5/8-inch jamb, adjustable steel tandem rollers, and a locking handle. The doors were rated SGD-R35 with a U-value of 0.30, making them an energy-efficient solution for both residential and commercial use.
All windows and doors were fabricated with 5/8-inch colonial-style between-the-glass grids and Vitro SB-60 low-E glass with argon gas filling. The insulated glass units (IGUs) were 7/8-inch thick for the windows and 1-inch thick for the doors, further enhancing their energy efficiency.
This case study demonstrates how Crystal’s products can be successfully integrated into large-scale projects when installed according to manufacturer specifications. The use of thermal breaks, proper flashing, and high-performance glazing played a key role in achieving the desired energy efficiency and aesthetic outcomes.
