Product Overview

Introduction As an alternative to standard aluminum storefront systems, Pacific presents the curtain wall

system with wood interior. This system is ideal for applications where one desires a structural

window wall with the warmth and richness of wood on the interior, with the durability and low-

maintenance of aluminum on the exterior. Wood exterior caps are also available for a more

natural appearance, without compromising any of the performance integrity of the system.

When viewed from the exterior, the Curtain Wall System from Pacific Architectural Millwork

resembles typical aluminum storefront, with nearly unlimited configurations and multiple

aluminum cap options. The wood interior can be milled out of a variety of species and in nearly any profile, and is engineered

according to the structural and performance needs of the opening. The system has been AAMA tested for air, water and structural

performance and is also highly efficient in terms of thermal performance (NFRC test data available upon request).

Once the framework of the Curtain Wall System is established, the openings can be glazed with a variety of fixed and operable units,

including casements, awnings, swing doors, or any of our sliding and folding View-Wall systems. The openings can also be glazed

with aluminum clad wood panels, spandrel glass, or triple-glazed insulated units. Multiple installation options exist for Curtain Wall

Systems to span multiple stories and incorporate into any building system, which is why early planning in the design phase is critical.

All systems can be sold with third-party engineering and installation, to ensure proper performance and provide a turn-key solution.

Technical Overview The Curtain Wall System

by Pacific Architectural

Millwork consists of a non-

load-bearing structural

wood interior with a triple

layer of interior gaskets

and precise inner sealing

channel. The base profile

wood is fixed to the wood

with a direct screw connection. A variety of exterior caps are

available, which also assist to channel water away from the

glazed openings.

The interior wood components are 56mm (2-3/16”) in

thickness, with a variable depth depending on the structural

needs of each opening.

A structural core is used for stability and consistency in the

interior wood components, with ¼” veneer in a variety of

wood species. Vertical and horizontal lengths can be

configured to create nearly any desired combination and

span multiple stories. Angled corners and segmented radius

systems are also available.

Exterior Aluminum Cap Options

The Curtain Wall System can be configured with a variety of aluminum exterior cap options to meet any design. The exterior is

available with an anodized or custom color-matched Kynar™ finish for durability and low maintenance. Additional cap profiles are

available.

STANDARD VERTICAL CAP PROFILE: 15mm x 56mm (5/8” x 2-3/16”)

STANDARD HORIZONTAL CAP PROFILE: 12mm x 56mm (1/2” x 2-3/16”)



Exterior Exposed-Screw Options

Choose an exterior exposed-screw option for a more industrial look. Additional profiles are available.



Exterior Wood Cap Option

An exterior wood cap lends a more natural appearance to the Curtain Wall System, without relying on the integrity of the wood

material for the weather performance of the system. The wood cap can be custom-milled to suit your design.

Vertical/Horizontal Mullions: Aluminum Cap

See below for the vertical and horizontal mullion profiles with standard 12mm/15mm aluminum caps. The depth (T1) of

the interior wood component varies according to structural requirements (50mm min.), and can differ between the

vertical and horizontal mullion. The profile of the interior wood can be customized to meet your design needs.

Vertical/Horizontal Mullions: Wood Cap

See below for the vertical and horizontal mullion profiles with a sample wood cap. The depth (T1) of the interior wood

component varies according to structural requirements (50mm min.), and can differ between the vertical and horizontal

mullion. The profile of the interior wood and exterior wood cap can be customized to meet your design needs.
