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.
