The NewTechWood All Weather Siding – Vertical Installation Guide (2025 PDF) provides complete, step-by-step instructions for installing NewTechWood UltraShield boards in a vertical cladding layout. This guide outlines furring requirements, AW08 clip placement, inside and outside corner details, bottom locking rules, butt-joint spacing, and finishing techniques for a clean and long-lasting vertical installation.
The manual begins with safety recommendations, proper handling of composite boards, and substrate preparation. Installers are reminded that NewTechWood must be installed on a flat, plumb wall surface and cannot be applied directly over existing siding. If the wall is uneven, the guide requires building a furring structure using either pressure-treated wood or aluminum furring strips spaced no more than 12″ on center.
A key rule unique to vertical installation is that **each board must be locked only at the bottom**, using the locking hole in the AW08 clip. The first two clips at the base of every board must be locked with screws, while all other clips remain floating to allow for expansion and contraction. The guide includes a full temperature-based expansion table to help installers determine proper end-gap spacing.
Installation begins by fastening inside or outside corner trims (US47 or US46) and inserting the first US09 siding board. A box-beam level is used to ensure the first board is perfectly plumb before continuing up the wall. Each additional board is inserted into the previous groove and fastened with AW08 clips.
Instructions are provided for installing last boards at both outside corners and outermost edges. These steps include measuring the remaining space, ripping the final board to size, pre-drilling oversized holes for movement, face-screwing the top with stainless steel fasteners, and installing F-Trim (US44) or Outside Corner Trim (US46). Cutting diagrams show correct measurements, aluminum angle placement at the base, and proper sequencing for trims.
The guide concludes with butt-joint options (with or without cut F-Trim), minimum bottom-clearing requirements, and two finishing methods for the top—metal flashing or modified F-Trim.
