The Thermory Cladding Installation Guide (2025 PDF) provides complete instructions for installing Thermory’s thermally modified wood cladding systems. This guide covers rainscreen requirements, ventilation, furring strip options, board spacing, attachment methods, and long-term care so your cladding performs as designed in every climate.
The document begins with storage and acclimation guidelines. Boards must be kept dry, elevated, and protected from sunlight before installation. For exterior use, cladding should acclimate for several weeks on-site, while interior applications require acclimation in a conditioned indoor space. The guide emphasizes inspecting all boards prior to installation, as installed material is considered accepted.
A rainscreen system is mandatory for all Thermory cladding. This includes continuous airflow behind the boards, created using vertical or horizontal furring strips depending on orientation. The airflow must remain open at the top and bottom of the wall and around all fenestration. The manual notes that drainage mats and non-vented barriers do not provide adequate ventilation.
Thermory specifies minimum furring thickness, spacing, and proper orientation for both horizontal and vertical installations. Vertical cladding requires a double-layer furring system to ensure full airflow. Horizontal cladding requires a single vertical layer. Windows and doors must maintain a 1/4″ clearance above and below for drainage and airflow.
Attachment options include stainless steel Solida screws, hidden fixing profiles, and PaCS aluminum strips for C7J and C23J profiles. The guide explains correct screw placement, minimum distances from edges and ends, and why nails and staples are not recommended. Detailed diagrams show proper tongue-and-groove engagement and expansion spacing.
Later sections outline maintenance expectations, including color evolution, oiling recommendations, hairline checking, and how to manage natural variations in grain and tone. A troubleshooting section addresses common issues such as cupping, humidity imbalance, and staining.
