Performance of EPS Sandwich Panels in Outdoor Conditions

Thermal Insulation and Energy Efficiency
EPS sandwich panels are great for keeping heat in or out. The expanded polystyrene (EPS) core stops heat from moving through. This keeps rooms cozy, no matter the weather outside. It also cuts down on heating and cooling costs. These panels help keep indoor temperatures steady, even in very hot or cold weather.
Their light weight also helps save energy. Lighter materials mean less energy is needed to move and install them. This makes EPS panels a smart, eco-friendly choice for modern buildings.
Tip: Seal the panels well during setup to avoid air leaks.
Moisture Resistance and Water Protection
EPS sandwich panels resist water, making them last longer outdoors. Unlike some materials, EPS doesn’t soak up much water. This helps it keep its insulation working well over time. Studies show EPS absorbs only 4.8% water after long exposure, while XPS absorbs 18.9%. After drying for 30 days, EPS holds just 0.7% water, but XPS still holds 15.7%.
Material | Water Absorbed (%) | After Drying (30 days) (%) |
---|---|---|
EPS | 4.8 | 0.7 |
XPS | 18.9 | 15.7 |
A 15-year study showed EPS stays much drier than XPS. It was four times drier when taken from a building base. This water resistance helps EPS panels stay strong and keep insulating, even in wet places.
Wind and Impact Resistance
EPS sandwich panels are built to handle strong winds and hits. They work well in tough outdoor conditions. Tests show they stay strong even after being exposed to heat and moisture. But, very high heat can make them less resistant to impacts. For example, panels aged at 70°C had 35.69% less contact force and 71.43% more bending.
Even with these issues, EPS panels are still dependable in windy or stressful areas. Their sturdy design helps them stay safe and effective in harsh weather.
Note: Check panels often to spot and fix wear early. This keeps them working well longer.
Fire Resistance and Safety Standards
EPS sandwich panels follow strict rules for fire safety. They are made to slow flames and keep buildings safer. The outer layers, usually steel or aluminum, block direct fire from reaching the core. This gives extra time to act during a fire.
The expanded polystyrene (EPS) core has special chemicals to fight flames. These chemicals help the core stop burning when the fire is gone. This lowers the chance of fire spreading through the panels. But remember, EPS panels resist fire but are not fully fireproof. Always follow local fire rules when installing them.
You can make the panels even safer with extra steps. Adding fire-resistant coatings gives more protection. Using firebreaks between panels stops flames from spreading. Regular checks keep the panels strong and fire-resistant.
Tip: Talk to a fire safety expert before using EPS panels. This helps meet safety rules and lowers risks.
