EPS Cement Sandwich Wall Panel Advantages

● Energy-saving, environment-friendly

Green and environment-friendly, non-harmful substance, no radiation, reusable, no construction waste, widely used in various places.

● Lightweight and economy

The core material of EPS cement exterior wall panel is filled with lightweight EPS. The volume-weight is about 600-800 kg/m3. Freely plastering and the weight is only 1/6 of the traditional wall.

● Fireproof

The non-inflammability of the Ojunda board can be reached national A level standard. Under the high temperature of 1000 degrees, the fireproof feature can last four hours, do not radiate toxic gasses.

● Waterproof and wetproof

The water container is made of Ojunda material without any waterproof plaster with no leakage at all. The tests show that the material has good waterproofness and dampproof. Ojunda material can be used in the wet area such as kitchen, toilet, and basement.

● Anti-pressure, anti-quake and anti-impact

Because of fabricated construction, 3-in-1 structure and using tongue and groove to join panels, the anti-pressure, anti-quake and anti-impact all meet the national standard.

● Sound insulation

Good sound insulation, sound absorption and noise reduction functions. For example, the amount of sound insulation is up to 40dB with the 90mm thickness of the wall board, which is 2 or 3 times than the traditional wall.

● Simple construction, high efficiency

Dry work, fabricated construction. EPS cement sandwich panel can be arbitrary cut according to specification. During the construction of transportation concise, pile up, no need of mortal health file, greatly reduction the time duration, and the calibration material, reducing the low construction waste. Easily transported, clearly stack and no mortar batch file largely shorten the construction period. Besides, the construction waste can be reduced by the lowly loss rate.

● Heat preservation

Wall materials mainly are made from environmental protection and energy saving heat insulation material. With a good heat insulation and preservation function, it can keep the indoor temperature at a stable range and make the environment much more comfortable.

● Spiking and stickability

EPS cement sandwich panel can be nailed directly and install expansion bolt to hang heavy loads, such as TV, air conditioner, water heater. single point of hanging strength is above 45kg.

● Easier for decoration

can be decorated by ceramic tile, wall paper, wood panel and other materials due to the smooth and ash-free features.

● Increased the usable area

The thickness of the board is between 50mm-200mm. It largely saves the construction space compared with the traditional block.

● Reusable

Can be reused in the movable interior wall such as supermarket, office, etc. The lightweight energy-saving wall board can be reusable. Dismounting and installation are simple and improved usage rate and economy saving. Also it has no construction waste and no affect other people's normal work.

EPS Cement Sandwich Wall Panel installation stEPS

1. Setting the line and carrying the board into position

Make base lines on the floor, ensure the panel and the beam is vertically, two peope carry the panels to the right position.

2. Sawing board

Using hand-hold electric saw freely according to the specification of wall, which can reduce the loss rate.

3. Sizing

Sizing the bump slots and then spread the baseline and the bump slots with the special adhesives.

4. Installation

Carrying the board prepared to be installed to the installation place, correcting the wall board by Special tools, and making it close tightly, and let the polymer mortar squeeze out into full and then fixing it with a wedge temporarily

5. Correcting, fixing 

Using a guiding rule of two meters to check the verticality and leveling correction. Then using 6mm or 8mm reinforcing steel bar and ribs adding with construction sealant to fix.

6. Grouting and filing starch

Using the special adhesives to fill the gaps between boards one day after correcting wall. Then putting the chock out and letting the corrected wall smoothly with polymer mortar.

7. Grooving and piping ,Sticking anti-cracking tape

Cutting a groove by a hand-hold electric saw for burying the concealed wire and switch box. Then filling with polymer mortar after installation. 

After finished grouting 3 or 5 days, then sticking anti-crack tape or attaching fiber mesh cloth if need second decoration

8. Door and window

Preparing a door and window hole on the installed wall, anchoraging it with splint or lines.

9.  Facing ceramic tile, decorative sheet, coating and wall paper

Sticking ceramic tiles, or wood facing panels and coating directly on the installed wall without plastering.
