Reduce Building Cooling Costs by 30%: Energy Efficient Window Film Solutions

1. Why Are Windows a Primary Source of Heat?​​

Windows bring in natural light but also heat. Research shows that in the world, up to 30% of home cooling energy can be lost through windows​​

. Key reasons include:

• Sunlight contains infrared (IR) radiation, which transfers heat.
• When sunlight passes through unprotected windows, it heats indoor surfaces like floors, furniture, and walls.
• Stored heat then radiates into the air, forcing AC systems to work harder.
• Large windows or south/west-facing onesare especially vulnerable in hot climates, accumulating intense afternoon heat.

2. How Does Window Film Reduce Heat?​​

Window film acts as a thermal shield for glass. Installed on the interior surface, it:

• Blocks heat-carrying infrared raysand fade-causing ultraviolet (UV) radiation.
• Reflects and absorbs solar energybefore it enters indoors.
  Result: Cooler interiors, reduced AC usage, and lower utility bills.

Our KASHIBANG Frosted Series White Out film delivers exceptional energy savings, blocking up to:

• 5% of harmful UV raysand
• 99% of total solar energy(depending on tint level).

3. Real-World Cost Savings​​

Per the International Window Film Association (IWFA), homeowners in hot climates can save up to 30% on cooling costs with professional-grade film

. For a household spending $300/month on summer AC,this means:

• 100/monthsaved to 600 saved over a 6-month cooling season.
  Many window films pay for themselves in one summer.

Savings depend on:

1.Window size/orientation (south/west-facing maximize gains).

2.Local climate.

3.Film type (e.g., ceramic vs. metal coatings).

4.AC efficiency.

Bottom line: Less solar heat gain = Lower cooling demand = Reduced bills.
