What makes sandwich panels ubiquitous in the prefab construction industry?
Wall claddings done with sandwich essentially consists of three layers – one core insulating layer which is dense and two outer layers of metal sheets. The inner layer is the one that has high insulation properties. It can be polyurethane, mineral wool, EPS, etc. The two outer sheets are pre painted galvanized iron metal, which supports the inner layer. Special adhesives and foaming techniques are applied to keep the three layers together.
Insulated sandwich panels are commonly used for wall and roof claddings in a prefabricated building. Be it industrial, commercial, institutional or any infrastructure, sandwich panels are versatile and find application in all types of building. But what are the benefits of using these panels? Let’s look at it below:
- Lightweight – easy to transport and assemble
A sandwich panel is lightweight, albeit being sturdy. This helps save a lot of weight without compromising on the structural strength of the building. The inner core insulation also helps preserve adequate room temperature.
2. Fast installation
Sandwich panels come with tongue and groove jointing systems. And being lightweight, they are quite easy to load/unload on a truck for transportation. It does not require too much time. So installation can be done fast with a handful of people.
3. High thermal insulation
Mineral wool or rockwool insulation has thermal and sound insulation capabilities, while polyurethane panels also have thermal insulation. This is one quality that makes sandwich panels the most sought after choice as it helps maintain room temperature, not allowing excessive heat to radiate in. This keeps a the working environment snug and you need not incur high electricity bills.
4. Excellent fire resistive and sound insulation properties
Rockwool insulation is known for having fire resistive capability. It can prevent fire from spreading beyond a certain area. Apart from casualties, fire damage can cause losses worth crores. So fireproofing a building is of utmost importance.
Sound insulation is another important factor, especially if your office and factory is located adjacently. Be it having a conversation or focusing at work, noise can cause massive disturbances – a factor which is often overlooked.
