light weight easy installation EPS foam cement sandwich panel

Sandwich Panel
1. Introduction
Kam Chung sandwich panel is a new building material composed of calcium
silicate panel, Portland cement and EPS foam. Compared with traditional brick
wall, it is light in weight and can save a lot of construction space. Besides,
it is waterproof, soundproof, weatherproof and fire-rated, which makes it
versatile in applications.
2. Application
Kam Chung sandwich panel could be used as interior partition wall for
apartment, office, factory, residential complex, shopping mall, KTV center,
refrigerated storage etc. It’s excellent for buildings with special
requirements on sound and temperature. Also its advantages of light weight and
weather resistant make it a good exterior wall for warehouse, bungalow,
temporary house, labor house, security guard room and so on.

5. Installation Processes for Sandwich Panel
(1). Draw lines on wall and floor according to drawing plan.
(2). Cut Kam Chung sandwich panels into suitable sizes with a circular saw.
(3). Mix cement and sand (ratio 1:2) and make it starchy. Then wet panels’
sides which are to be connected and put cement mixture on them.
(4). Fix the panels according to drawn lines and keep them upright. Use a jimmy
to move the panels from bottom and make them tightly connected to each other.
(5). Push panels so as to again make sure they are tightly combined and squeeze
out the cement mixture from connecting joints. Then use wedges to fix them.
(6). Use a 2-meter long guiding rule to check the flatness and perpendicularity
of panels. Adjust them with a jimmy and fix them with wedges and steel bars.
(7). All joints between two boards must be reinforced with steel bars in size
6*200mm at 45 degree angle.
(8). After adjusting panel connections, use 30*30mm wedges to fix them. Then
use a drill to make holes through panels and floor at a 45 degree angle. Hammer
6*200mm steel bars into the holes to tightly fasten panels on the ground.
(9). When adjusting and fixing are finished, fill all joints with cement
mixture, including those connected with ceiling and floor. Pull out the wedges
and stuff the holes with cement mixture.
(10). If embedded channels are needed, use a circular blade to cut on panels
and cover them with cement mixture once embedding is finished.
(11). Last step is to cover the walls if necessary. Wallpaper can be pasted,
wood plate nailed and ceramic tiles directly stuck on them with cement mixture.
Door and windows could be fixed right on them as well.
