Different installation options for FleeceBack TPO membrane

FleeceBack TPO membranes can be installed using various methods according to the specific needs of a roofing project. The primary
installation options include:

1. Fully Adhered System: This method involves applying adhesive to the roof deck or insulation and to the fleece backing of the membrane itself. After the adhesive is spread and allowed to become tacky, the FleeceBack TPO is rolled out onto the surface and pressed into place. The fleece backing provides a strong bond to the adhesive, creating a secure, watertight roofing system.

2. Mechanically Fastened System: In this approach, the membrane is attached to the roof deck using fasteners and stress plates. Although the fleece backing doesn't play a direct role in the mechanical attachment, it can provide an extra cushion and help protect the TPO membrane from potential damage from the fasteners.

3. Ballasted System: Ballasted installations involve laying the membrane loose and then holding it in place with a layer of ballast, such as river rock or pavers. The weight of the ballast keeps the membrane secure. While this method is not as common for FleeceBack membranes due to their adhesive-friendly nature, it can still be used in certain designs where appropriate.

4. Self-Adhered System: Some fleece-backed membranes come with a pre-applied adhesive layer protected by a release film. During installation, the release film is removed, and the membrane is rolled onto the substrate. This method can offer a cleaner and quicker installation process with fewer fumes compared to traditional adhesives.

5. Induction Welded System: With the induction welding method, specially designed plates are placed underneath the membrane, which are then fastened to the deck. An induction welding tool is then used to heat the membrane and the plate, causing the two to fuse together. This system allows for a high-performance bond and is good for roofs with high wind uplift requirements.

The choice of installation method for a FleeceBack TPO membrane depends on the building design, the local climate, the roof deck type, and other factors such as cost, labor efficiency, and desired performance characteristics. Each method has its benefits and considerations, and a professional roofing contractor can help determine the best option for a particular project.
