Direction External Heat Insulation Wall Thailand
for Thailand The trend may be 'Increase efficiency' of fireproof materials Fireproof walls that must be fireproof for a specified period of time. Both internal heat-insulating walls (Internal Insulation Wall) and external heat-insulating walls (External Insulation Wall ) Entrepreneurs should study the law carefully and adjust accordingly through expert service providers. Because if there are gaps or leaks, problems may occur such as moisture, dirt, ineffective cold storage, etc.
How to Choose the Right External Wall Insulation
Consider these 7 features before you buy external wall insulation.
- Low heat conductivity to maintain temperature in buildings
- Customizable (Color, size, and thickness)

Types of External Wall Insulation
ผนังกันความร้อนExternal wall insulation is classified into 4 types, each with its advantages and disadvantages.
1. EPS External Wall Insulation (Expanded Polystyrene)
EPS Panel (Expanded Polystyrene Foam) is a low-cost external wall insulation. It provides average heat insulation and high water absorption. The lifespan is short (10 years). It is not weather resistant and if exposed to fire, it will melt and cause damage to the structure.
2. PU External Wall Insulation (Polyurethane)
PU Panel (Polyurethane) is external wall insulation that can protect against fire and harsher weather than EPS Panel. However, if exposed to fire, it will create a massive amount of toxic smoke mixed with Hydrogen Cyanide that can harm personnel severely.
3. WALLROC Rockwool External Wall Insulation
Rockwool WALLROC is a special external wall insulation from the collaboration between Wall Tech and the Rockwool Group. This external wall can withstand fire for more than 4 hours, has excellent heat insulation, high durability, and a Z-Lock system, a high-quality locking system that can withstand most weather conditions.

4. PIR External Wall Insulation (Polyisocyanurate)
Authentic PIR Panel (Polyisocyanurate) is an external heat-resistant wall that has a special feature of creating a carbon layer covering the surface when combustion occurs. This allows the fire to extinguish itself without smoke. Moreover, in terms of heat protection, it is also the best. Supports temperatures as low as -60 and as high as 100 degrees Celsius, combined with the use of an innovative insulation panel locking system ZIP-Lock Eliminates gaps, leaks and provides excellent protection against wind.
