Powerdaylight Cradle Eco delivers exceptional insulation performance with a U-value of 0.7 W/m²K

At Powerdaylight, we set out to prove that natural daylight can go hand in hand with outstanding thermal performance. Independent testing now confirms that our daylight tube achieves an impressive U-value of just 0.74 W/m²K — far better than many competing systems, which often report values of 2.0 W/m²K or higher.

This significant difference matters to both homeowners and professionals.

For homeowners

A lower U-value means your home loses far less heat through the roof. This results in:

• Lower energy bills
• A warmer, more comfortable living space
• No cold spots or drafts beneath the daylight tube
• A more energy-efficient home all year round

You enjoy the benefits of natural daylight without compromising on comfort or efficiency.

For commercial partners

Installers, roofers and distributors benefit from offering a product with proven, superior insulation performance. A U-value of 0.74 W/m²K provides:

• A strong competitive advantage over systems with U-values of 2.0+
• Reduced risk of condensation, cold bridges or customer complaints
• Compliance with modern insulation standards and expectations
• A premium product that reflects high-quality workmanship

With rising energy prices and stricter building requirements, the market increasingly demands solutions that combine performance, sustainability and reliability. Powerdaylight delivers exactly that.

When considering a product, always check the u-value and ask for a copy of the test report!
