This system comprises several vital parts that work together to provide an effective adjustable continuous insulation solution.
Base Brackets:
GreenGirt CMH Delta Adjustable base brackets, consisting of a composite metal hybrid material, come in two profiles – Z-profile with a front flange and L-profile without a front flange. They also come in two types: expansion base brackets and fixed base brackets. Both are utilized within a complete wall system to allow for expansion. These base brackets form the system’s foundation and are designed to be installed vertically according to shop drawings. The base brackets offer adjustability for up to 10.5″ away from the substrate, catering to varying insulation systems and plane deviations.
Expansion Base Bracket
Fixed Base Bracket
All base brackets come equipped with a pre-punched metal insert in the flange installed against the substrate, enhancing structural integrity and ensuring a firm and secure installation without sacrificing thermal performance.
A unique feature of these base brackets is the Dual Grip™ technology. This state-of-the-art technology is designed to securely hold the clip or L-rail in place while adjusting to the required plane before side-stitching. The result is a firm and robust connection that facilitates the smooth installation of the system and enhances its overall stability and durability. In addition, the Dual Grip technology assists in an efficient story pole installation technique, saving labor and time.
Mineral Wool Insulation:
Insulation is the core material that provides thermal resistance and enhances the energy efficiency of the building. Base brackets, rails, or hat channels hold it in place on the wall, forming a continuous layer of insulation across the building’s exterior.

L-Rails:
L-rails, available in steel, aluminum, or composite metal hybrid materials, attach to the base brackets using side-stitch fasteners. Standard L-rails come in 8′ lengths but can be customized as needed. L-rails allow for a quick and easy installation process of base brackets with the story pole technique. L-rails also serve as the secure mounting platform for the cladding application. They should not cross movement joints and must leave a ½” gap at all joints.

Aluminum L-Rail
Clips:
Clips are 6″ long and have a similar L-profile to an L-rail. They are typically used in place of L-rails for horizontal applications. They are also available in steel, aluminum, or CMH.
Hex Head Screws:
These screws are used to secure base brackets to the substrate, providing a stable structure when assembled.
Washered Side-Stitch Fasteners:
These fasteners attach the L-rails to the base brackets. They must be centered in slots on expansion base brackets to allow for expansion.
Each component has a unique role in the system and contributes to providing an adjustable continuous insulation solution. Understanding the functionality of each element is essential to installing the GreenGirt CMH Delta system and maximizing its benefits effectively.

Step-by-Step Installation Process
Installing the GreenGirt CMH Delta Adjustable continuous insulation system requires careful attention to detail and adherence to instructions. Here’s a step-by-step guide to help you through the process.
Preparation of the Installation Site:
Start by preparing your installation site. Ensure the area is clean, clear of debris, and ready for installation. This includes checking the substrate for any irregularities that might affect the installation.
Installation of Base Brackets:
Begin the installation with the base brackets. These should be installed vertically per shop drawings and project-specific requirements, using the pre-punched metal insert in the flange closest to the substrate for structural integrity. The shop drawings and sample layout show the placement and order of expansion brackets vs. fixed brackets. Base brackets can be installed using a story pole installation method for a quick and easy way to consistently and evenly place the base brackets against the substrate. Remember to use the Dual Grip technology to hold the clip or L-rail securely.
Placement and Attachment of L-Rails or Clips:
Place the L-rails or clips into the base brackets. Shim and level the L-rail or clips out to the required plane. This adjustment must accommodate varying insulation thicknesses, cladding systems, and building requirements. Remember never to leave an L-rail or clip non-mechanically attached to a base bracket.
Use of Side-Stitch Fasteners:
Use two side-stitch fasteners per every base bracket to secure the L-rails in place, ensuring a firm and robust connection. Side-stitch fasteners should always go from the fiber-reinforced polymer (FRP) material and bite into the metal L-rail or clip. The purpose of this is to maximize fastener retention. Install side-stitch fasteners in the center of the pre-punched slots on the expansion base brackets to allow for expansion.
Ensuring Thermal Expansion Accommodation:
Finally, ensure the system can accommodate thermal expansion. Leave a ½” gap (or as specified in the drawings) between L-rail joints. Use three fixed brackets per 10′ steel rail, with the rest as expansion brackets. For aluminum rails, use two fixed brackets per 10′ rail, with the remainder as expansion brackets. Steel rails less than 6′ long and aluminum rails less than 4′ long do not need expansion brackets.
Installation of Insulation:
Remember, the success of your GreenGirt CMH Delta Adjustable continuous insulation system installation lies in following these steps accurately and carefully. Always refer to the installation guide for detailed instructions and additional pro tips through the installation process.
Post Installation Checks
- Checking for Proper Alignment: Check the alignment of the base brackets and L-rails. The base brackets should be vertically aligned per the shop drawings and sample layout, and the L-rails should be adjusted to the required plane. It is crucial to ensure everything is aligned correctly.
- Verification of Secure Attachments: Next, verify that all attachments are secure. This includes the attachment of the base brackets, L-rails, and insulation. Check to ensure that all fasteners are secured and that there is no movement or looseness in the attached components.
