IV. Step-by-Step Installation Process

Installing the GreenGirt 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 for maximum fastener retention. Side-stitch fasteners should be installed in the center of the pre-punch slots on the expansion base brackets to allow for expansion.

Ensuring Thermal Expansion Accommodation:

Finally, ensure the system can accommodate thermal expansion. This can be done by leaving a ½” gap (or as per drawings) between L-rail joints. For steel rails, three fixed brackets are needed per 10’ rail and the rest must be expansion brackets. For aluminum rails, two fixed brackets are needed per 10’ rail and the rest must be expansion brackets. Steel rails less than 6’ long and aluminum rails less than 4’ long do not need expansion brackets.
