Structural Insulated Panel (SIP)
Strong, durable, lightweight, heat-insulating, and fast installation
Say goodbye to old problems with ConTel Wall, an interior heat-insulating prefabricated structural wall (Sandwich Panel / Structural Insulated Panels – SIPs). This technology has been developed in the United States for over 50 years. It combines strength, durability, lightweight properties, and excellent heat and moisture resistance, helping you save on time, labor, and electricity costs in the long run.
The secret behind the strength and premium heat insulation properties of ConTel Wall comes from sandwiching 3 main layers of engineering-grade materials together (Sandwich Panel):
If you are in the process of choosing materials for partitioning rooms or making interior walls, here is an in-depth feature comparison table that will help you clearly see which wall best meets your needs:
| Technical Features and Usage | ConTel Wall Prefabricated Wall | Isowall (General EPS Foam) | Autoclaved Aerated Concrete (AAC) Brick Wall | Red Brick / Concrete Block Wall |
|---|---|---|---|---|
| Surface Material (Skin) | MgO Board: strong, smooth, easy to paint/decorate immediately | Color-coated metal sheet | Requires plastering on both sides | Requires plastering on both sides |
| Thermal Conductivity (K-Value) (Lower = better insulation) | 0.054 (Lowest thermal conductivity) | ~0.038 - 0.060 (Similar, depending on the steel) | 0.098 (Medium thermal conductivity) | 0.436 - 1.14 (High thermal conductivity, makes house hot) |
| Thermal Resistance (R-Value) (Higher = better insulation) | 1.30 (Highest thermal resistance) | High (Good heat insulation) | 0.08 (Lowest resistance) | 0.30 (Medium resistance) |
| Installation Speed (2 workers / day) | 25 - 30 sq.m. (Fastest, dry system) | 20 - 25 sq.m. (Dry system, but beware of dents) | 15 - 20 sq.m. (Medium, must wait for cement to set) | 5 - 10 sq.m. (Slowest, many steps involved) |
| Drilling / Hanging Load | Can support up to 42.6 kg/point (Can be fixed anywhere without wall anchors) | Low load capacity, must be anchored to the internal steel frame only | Supports 30 kg/point (Brittle block material, requires specific anchors) | Supports 15 - 30 kg/point (Requires anchors, drilling mistakes can break the brick) |
| Total Material Weight (including plaster) | 19.30 - 20.23 kg/sq.m. (9 times lighter than brick) | ~12 - 15 kg/sq.m. (Very light, but low impact resistance) | 90 kg/sq.m. (Medium) | 150 - 180 kg/sq.m. (Very heavy, adds load to the structure) |
| Aesthetics and Decoration | Smooth surface ready to use. Can be painted, wallpapered, or tiled immediately. | Corrugated steel sheet, suitable for factory work, difficult to decorate further. | Requires corner rendering and smooth plastering, risking cracking problems later. | Requires corner rendering and thick plastering, risking wavy and cracked walls. |
ConTel Wall vs. Brick Walls (Red brick / AAC):
Brickwork causes a messy worksite with dust and cement waste. Moreover, bricks accumulate high heat, causing air conditioners to work harder. In contrast, ConTel Wall is a dry installation system (Drywall System) that reduces worksite waste. It is also up to 9 times lighter, helping to reduce the size of the structure, columns, and beams, which inherently saves on building costs.
ConTel Wall vs. Isowall:
Although Isowall stands out in industrial cold room applications due to a similar foam core, its exterior metal sheet surface makes it unsuitable for residential living. This is because it dents easily, produces a loud noise when knocked, and makes the building look like a factory. This is different from ConTel Wall, which utilizes MgO Board surfaces to provide a smooth texture resembling actual plastered walls. It is highly resistant to impact and can be beautifully painted and decorated to perfectly fit into homes, condos, or luxury offices.
The wall panels are large and lightweight, making them easy to lift and install. The worksite is finished 5 times faster, saving a massive amount on labor costs.
The joint system is designed for convenient side-by-side assembly. It can be used for both steel structure buildings and reinforced concrete structures.
The material is highly durable yet lightweight, weighing only 20 kg/sq.m., which is significantly lighter than traditional masonry walls.
Perfectly adaptable as partition walls for any space layout. Highly recommended for diverse projects including hospitals, restaurants, hotels, schools, residential homes, modular houses, factories, theaters, and boardrooms.
It passes the HB UL 94 fire-retardant standard, and the exterior surface prevents water penetration. Even when facing rainstorms, it will not swell or rot.
With a Thermal Resistance (R-Value) as high as 1.30, it is very difficult for external heat to pass through.
Be confident with drilling and anchoring test results, supporting weights up to 42.6 kg/point without the need for wall anchors.
The installation of the ConTel Wall prefabricated wall is a dry system that saves time and reduces complications, consisting of the following main steps:
Step 1: Install the steel frame – Fix and install a C-80×30 mm steel frame to the floor and ceiling along the designated wall line.
Step 2: Insert the first panel – Lift the ConTel Wall panel and insert it into the C-frame, starting from the innermost corner of the wall.
Step 3: Insert the joining frame – Insert a C-80×50 mm steel frame into the side groove of the first wall panel, then secure it tightly with screws.
Step 4: Assemble the next panel – Lift the next wall panel and insert it into the side C-groove, continuously joining them together until the wall line is complete.
Step 5: Apply a thin finish – Apply a skimcoat specifically to the joints between panels and screw heads, without wasting time plastering the entire wall. Once dry, it can be painted or wallpapered immediately!
