SECTION 097753 – LIVING WALL SYSTEM (ALTERNATE BID)

PART 1- GENERAL

1.1 SUMMARY

A. Scope

1. Work includes furnishing and installing the VerTexx® LivingScreen System;

including all mounting components, planting trays, GardenSoxx®, plants, and irrigation components, as designated on the construction drawings and as specified herein (BASIS OF DESIGN).

B. Description

1. The VerTexx® LivingScreen System is made of galvanized wire panels and sturdy planting trays to easily create custom vegetated vertical screens.

VerTexx trays hold 5” diameter GardenSoxx units in typical 24” lengths and can be pre-grown with vines to the specified height (typically to the top of the

VerTexx Trellis wire panel). The GardenSoxx mesh keeps weed seeds out, and added optional irrigation creates a completely low-maintenance growing system. Typical VerTexx Trellis (wire panel) dimensions are 4’ wide x 6’ tall with openings of 4” W x 6” T; however, 4’ and 8’ tall panels are available by special order. The VerTexx LivingScreen System is designed to be installed in accordance with these specifications and the Filtrexx installation manual.

VerTexx LivingScreens utilize open bottom VerTexx trays along the bottom edge of the wire panel, to allow for roots to grow through, and vines to populate the blank wire above.
