When people talk about thermal insulation, many automatically assume:

“The thicker the insulation, the cooler the house.”

As a result, many believe that increasing insulation thickness will always improve indoor comfort.

However, in reality, insulation performance is not determined by thickness alone.

What matters more is how effectively the material blocks heat transfer.

An insulation material can be very thick but still perform less efficiently than a thinner material specifically designed for high thermal resistance.

Common Misconception: Thicker Means Cooler

Many people choose insulation based only on thickness measurements.

But from an engineering perspective, cooling performance depends on several factors, including:

• Thermal conductivity value
• Material density
• Installation quality
• Air leakage prevention
• Seamless surface coverage

Insulation with gaps, joints, or uneven installation can allow heat to pass through, regardless of thickness.

TECO PU FOAM Works Differently

TECO PU FOAM uses a spray-applied technology that bonds directly to the metal sheet surface.

Once applied, the foam expands and adheres tightly, creating a seamless insulation layer.

Key advantages include:

✔ Eliminates gaps and weak points where heat can enter
✔ Reduces heat buildup beneath the roof
✔ Helps prevent moisture and condensation
✔ Reduces noise from rain impact
✔ Improves air-conditioning efficiency

This means high performance can be achieved without relying on excessive thickness.

Available in Only 3 Thickness Options: 3 mm, 5 mm, and 10 mm

TECO PU FOAM is designed to provide strong insulation performance while maintaining a slim profile.

Available thickness options:

• 3 mm
• 5 mm
• 10 mm

These thickness levels are suitable for various building applications while helping reduce additional structural weight and installation space requirements.

Can Reduce Indoor Temperature by More Than 40%

TECO PU FOAM creates a protective barrier that reduces heat transfer from the roof into the building.

Its seamless spray technology minimizes weak points and creates consistent insulation coverage.

As a result:

TECO PU FOAM can help reduce indoor temperatures by more than 40%.

Benefits homeowners and building owners may experience include:

• Cooler indoor conditions during hot weather
• Reduced air-conditioner workload
• Lower electricity costs
• Improved overall comfort

Thinner Design Means Lower Weight and Easier Installation

High-performance insulation does not always require large thickness.

Additional benefits include:

• Less load on the roof structure
• Space-saving installation
• Faster application process
• Reduced installation time

Suitable for:

• Residential homes
• Factories
• Warehouses
• Retail stores
• Office buildings
• Large commercial facilities

Conclusion

The belief that “thicker insulation always means better cooling” is not necessarily true.

The real factor is insulation efficiency.

TECO PU FOAM proves that even with thickness options of only 3 mm, 5 mm, and 10 mm, effective heat protection can still be achieved, helping reduce indoor temperatures by more than 40%.

Because a cooler home does not always begin with thicker insulation.
