WALL PANEL: A non-structural element that forms a curtain wall with loads transferred from the wall panel to a structural frame.
WALL PANEL ADVANTAGES: The cost and maintenance is low for metal wall panels since there is possibilities for customization and availability. It is quick and easy to install and there is a small amount of scrap after it is installed. Its lifespan is from 20 to 40 years and doesn’t require as much replacement as other wall systems. They are strongly resistant to fire so insurance cost is lower for metal panels and lower cost of utility since they are insulated to resist heating and cooling. If constructed right, the metal panel seams help keep water out. Another great benefit is its lightness compared to materials like brick. It is also sustainable and energy efficient because it can be 100% recycled and still remains strong as its original state.
COMPOSITE WALL PANELS
INSULATED METAL PANEL
TRADITIONAL METAL PANEL(SECTION)
A traditional metal panel system is connected to a metal wall stud. On the exterior of this wall system is the metal panel and on the interior is a piece of gypsum board. In between these two is a layer of air permeable waterproofing. Then there is a sheathing layer and stud cavity insulated with batt insulation. Following the batt insulation and metal studs is a vapor barrier/air barrier to block off moisture from entering the wall.
What is a rain screen?
Our project site, the Dream Hotel in NYC, consists of a stainless steel rain screen. A rain screen is essential to manage moisture in a facade. A rain screen wall should include a water-resistant barrier, an air gap between the water-resistant barrier and the back of the siding, flashing at vulnerable penetration areas, and weep holes at the bottom of the wall.
Types of rain screens.
A rain screen can be a “pressure equalized system” or a “drained and vented system.” The first type of rain screen deals with external wind loads and pressure equalization within the cavity. This system minimizes force on the wall and moves moisture through the outer wall.
The second type if rain screen system requires water to be collected and drained out of the wall. Water that penetrates the outer wall is collected and directed out of the cavity by using flashing and weep holes. If the outer wall is more airtight, pressure builds up and causes water to penetrate the interior wall and can cause decay.
