The NewTechWood All Weather Siding – Ceiling Installation Guide (2025 PDF) provides complete instructions for installing NewTechWood UltraShield siding boards as a ceiling system. This guide covers furring layouts, AW02 starting trim, AW08 locking clips, expansion and contraction requirements, butt joints, cutting details, and final trim installation.
The manual begins with safety guidance, required tools, and environmental notes, including storing boards on a flat surface and avoiding colored chalk during layout. Installers are reminded that NewTechWood boards cannot be installed directly onto a solid surface—proper ventilation requires a minimum 1″ continuous airspace beneath the ceiling system.
Furring installation includes spacing furring strips no more than 12″ apart and choosing appropriate stainless-steel screws (#8 × 3″ for furring, #8 × 1″ or #8 × 1¼” for clips, depending on substrate). Separate tables outline recommended screw types for **wood furring** and **aluminum furring**.
A critical section explains NewTechWood’s expansion and contraction behavior. Ceiling boards must be locked at **only one point per board**, using the AW08 clip’s designated locking hole. Horizontal installations require locking the clip at the center of each board; vertical installations require locking at either the bottom or top depending on layout. The guide includes a full temperature-based expansion chart to determine correct gapping at walls and butt joints.
Installation steps show how to fasten the AW02 starting trim, slide the US09 ceiling board into the trim, attach AW08 clips at furring intersections, and properly gap boards based on temperature. Butt-joint installations use the US45 I-Trim and follow the same single-locking-point rule to prevent buckling.
Cut-board installation at the final row includes measuring remaining space, cutting US09 boards to length, adding the T-7 rubber stopper, pre-drilling expansion holes, and face-screwing the final piece into the furring strips.
Trim installation is completed with US05 fascia boards, miter cuts at corners, and spacing for movement.
