Rainscreen attachment systems are made up of fasteners and sub-frame components that connect the exterior components of a building directly to the interior framing. The shortfall of metal fasteners is that they create thermal bridging. Because metal is a good thermal conductor, thermal bridging occurs when these components create a path of least resistance allowing heat to escape in the winter, and cold to escape in the summer. Rainscreen attachment components fabricated from non-conductve glass fiber reinforced resin composites such as the StronGirt™ System manufactured by STRONGWELL, eliminate thermal bridging as well as condensation, and are structurally stronger than steel. Zero thermal bridging composite rainscreen attachments systems are environmentally friendly, create significant energy savings, and reduce carbon emissions.
Benefits:
- Lightweight 100% FRP system (no metal to rust or react).
- Thermally efficient replacement to metal cladding attachment systems.
- Superior pullout strength and can be installed vertically or horizontally depending on construction requirements.
- Works with all non-proprietary insulation.
- No in-field fabrication required.
- Invisible in rainscreen cavities.
- Double fastening system on front flange.
- Code compliant
Zero thermal bridging composite rainscreen attachment systems are environmentally friendly, create significant energy savings, and reduce carbon emissions.
STRONGWELL's StronGirt™ is the ideal continuous insulation (CI) cladding attachment support system. This all-FRP (fiberglass) pultruded composite uses a custom fire-retardant resin system and unique laminate design to offer superior pull out strength, excellent thermal efficiency, and the ability to work with any non-proprietary insulation (no routing or fabricating of rigid insulation is required). The geometry of STRONGIRT™ offers self-draining to clear rainwater, and weep holes can be pre-fabricated or added in the field for additional drainage needs. The product has been engineered for strength and stiffness to support cladding, insulation, and wind loads, while offering a simple, durable, cost effective solution for installers.
