The CRL (CR Laurence) brand is widely recognized in the construction and architectural industries for its high-performance glass systems, including windscreen systems, storefronts, and sealing solutions. These products are engineered for durability, precision, and ease of integration into modern building designs. This article provides a comprehensive overview of the installation instructions for CRL products based on information from official manuals, technical documentation, and certified guides. The focus is on three primary product categories: CRL AWS Aluminum Windscreen Systems, CRL Laguna Series Sliding Glass Door Systems, and Roxtec CRL Sealing Solutions.
Overview of CRL Installation Requirements
The installation of CRL products demands attention to detail, adherence to manufacturer guidelines, and a clear understanding of the materials involved. Whether it is a windscreen system for a rooftop pool area or a sealing solution for telecom shelters, each product has specific installation requirements that ensure both functionality and longevity.
Installation procedures often include steps for preparing the site, assembling components, securing hardware, and ensuring structural integrity. CRL products are typically compatible with both glass and reinforced wall mounting, offering flexibility for a variety of architectural designs. However, the method of installation can vary significantly depending on the product type and the specific model.
CRL AWS Aluminum Windscreen System Installation
The CRL AWS Aluminum Windscreen System is designed to provide protection against wind and weather while maintaining an open, unobstructed view. This system is often used in commercial and residential rooftop areas, such as the rooftop pool in Brooklyn, New York, referenced in the source material.
Key Installation Steps
Preparation of Stanchions and Posts
The system consists of 72-inch high aluminum posts that are slipped over steel stanchions. These stanchions are set into core-drilled holes in the footing. The posts are then positioned over the stanchions, allowing the glass panels to be inserted into the post channels.Glass Panel Installation
The glass panels, typically 72 inches by 48 inches and 0.5 inches thick, are designed to be slipped into the post channels from above. However, the source material notes that this method can be impractical due to the amount of play between the stanchions and the posts. As a result, hoisting the glass panels into place may be dangerous and difficult.Alternative Installation Method
A CRL representative recommended the use of silicone to secure the panels in place. However, the alternative method detailed in the source material was used for the Brooklyn installation. This method involves adjusting the alignment and securing the panels with alternative means to ensure stability and safety.Adjustments and Safety
To ensure the system functions correctly, adjustments may be necessary. This includes ensuring the posts are level and properly aligned with the stanchions. Safety precautions, such as the use of protective gear and proper lifting techniques, are also emphasized during installation.
CRL Laguna Series Sliding Glass Door System Installation
The CRL Laguna Series Sliding Glass Door System is designed for both residential and commercial applications. It features an "anti-lift" mechanism that enhances security and prevents unauthorized access. The system is compatible with tempered glass of varying thicknesses and can be mounted either to glass or to a reinforced wall.
Key Installation Steps
Kit Selection and Preparation
The Laguna Series offers four standardized kits: two for wall mounting and two for glass mounting. Each kit includes fasteners for either flush mounting (requiring a countersunk hole) or surface mounting (requiring a straight hole). The selection of the appropriate kit depends on the installation requirements and the structure being used.Cutting and Aligning the Sliding Tube
Before installation, the sliding tube must be cut to the appropriate length. This is typically done on a flat surface to ensure precision. The Wall Mount Clamps are then loosely assembled and hand-tightened before the sliding tube is inserted.Mounting the Door Stops
The left and right door stops are slid onto the sliding tube. It is important to ensure that each stop clears the outboard clamp to prevent any interference during operation. Once the tube is level, the glass clamps are tightened.Adjusting the Top Roller and Anti-Lift Mechanism
The top roller must be loosened to allow it to move freely up and down. The Anti-Lift Block is then removed and stored safely. The mounting fittings are also removed for later use.The top rollers are mounted onto the door using either countersunk or straight holes. The recommended tightening torque is 11 ft-lbs (15 Nm), and the use of Blue Loctite Threadlocker is advised to prevent loosening over time.
Leveling and Final Adjustments
Once the top rollers are in place, the sliding tube is supported at the appropriate level. The Set Screw at the top of the roller is tightened to secure the door in place. The door is then adjusted to ensure it is level and plumb. The floor guide is also adjusted to fit the thickness of the glass (either 3/8" or 1/2") and positioned to align with the wall.Final Assembly and Testing
After all components are in place, the door is rehung to ensure it engages with the floor guide. The Anti-Lift Block is then installed under the sliding tube and tightened with the Spanner Head Tool. The Anti-Lift Block must be adjusted so that the roller moves freely through the mounting clamps.A final test is conducted to ensure the door operates smoothly and that the anti-lift mechanism functions correctly. Any necessary adjustments are made at this stage.
Roxtec CRL Sealing Solutions Installation
The Roxtec CRL Sealing Solutions are designed for use in telecom shelters, cabinets, and enclosures. These seals are engineered to provide a secure and flexible sealing solution for a variety of cable, pipe, and fiber optic configurations.
Key Installation Steps
Selection of the Appropriate Seal
Roxtec offers several configurations for 4" and 5" holes. Each configuration is designed to accommodate different numbers and sizes of cables or pipes. For example, the CRL 4"/1 configuration is suitable for a single cable with a diameter between 24.0 and 54.0 mm, while the CRL 4"/9 configuration can accommodate up to nine cables with diameters between 4.0 and 16.5 mm.The external and aperture dimensions of each seal are specified to ensure compatibility with the installation site. For instance, the CRL 4"/1 has an external dimension of 115 mm and an aperture dimension of 98–99 mm.
Preparation of the Installation Site
Before installing the seal, the installation site must be prepared. This includes ensuring that the hole is clean, free of debris, and properly sized. The square packing space within the frame is used to house the sealing modules and the cables, pipes, or fiber optics.Installation of the Seal
The seal is installed by inserting the sealing modules into the frame. The modules are then compressed using the integrated compression mechanism to ensure a tight and secure fit. The light-weight design of the seal makes it easy to handle during installation.Adjustments and Final Checks
Once the seal is in place, adjustments may be necessary to ensure that all cables or pipes are properly seated and that the seal is functioning as intended. A final check is conducted to ensure that there are no gaps or leaks and that the seal is properly aligned with the installation site.Certifications and Compliance
The source material notes that certificates for these sealing solutions are continuously updated. Users are advised to visit the official website regularly to ensure compliance with the latest standards and regulations.
Additional Notes and Recommendations
Surface Protection and Maintenance
For products made from satin stainless steel, such as the CRL Laguna Series, maintenance is important to preserve the finish. Damaged areas can be repaired using abrasive pads like CRL Cat. No. SB7447F - CRL 3M™ Scotch-Brite™ Fine Pad. The direction of the grain should be followed during polishing to avoid further damage.
For long-term protection, CRL offers a two-step surface treatment system: CRL 6K Hydrophobic Surface Protection. This system includes a pre-clean solution and a protectant formula that, when applied correctly, provides three years of surface protection. More information can be found on the official CRL website.
