Energy Star Rating & NFRC Standards For Skylights

Several skylight brands advertise their products with the energy star logo attached, the certification and logo of energy star rating are from USA and is given to any product that can be proven to reduce energy usage.

The logo is used by many certified products and skylights is one of them, The Energy star logo is a registered trademark for USEPA and can only be used for the products that have been tested and certified to the NFRC standards.

Manufacturers that have their products tested to NFRC standards and have proven to have minimum performance requirement can then also apply to participate in the Energy Star scheme.

Consumers in USA can take advantage of the federal tax benefits when installing Energy Star qualified windows, doors, and skylights.

The usage of the energy star logo for skylights products was developed for USA climate and the qualification criteria are in the table below and can be found in the link underneath.



NFRC (National Fenestration Rating Council) is a US based organisation specialised in rating of fenestration products.

NFRC is a voluntary membership body, Manufactures can join NFRC membership to make their products visible to consumers in US.
Products tested to NFRC standards must be physically tested by an NFRC accredit laboratory like Intertek.

SolarBright Maxlight products have been physically tested to NFRC standards and its energy performance confirmed by Intertek. The U-factor & SHGC values of Maxlight skylights exceed qualification criteria set by energy star scheme, however Solarbright has not applied for the energy star program neither has listed its product with NFRC because SolarBright products are not sold in US market.

In our opinion an Energy Star Rating scheme developed for another specific country’s climate is not relevant to Australia’s market and associating its logo with skylight products outside that specific country is wrong, meaningless, and misleading.

Skylight Warranty – It Is All In The Tube!

Most Tubular Skylights Only Have A 10-Year Warranty. MaxLight’s Have 20-Years. Why The Big Difference?

If you are considering brightening your home with tubular skylights, you need to consider that not all skylights are made equal. Most so-called “industry leading” tubular skylights come with only a 10-year warranty for the customer, whereas the MaxLight skylight, designed and manufactured in Australia by SolarBright, offers the industry best 20-year warranty on the tube.

Before we explain why, let’s look at the major components that make up a tubular skylight.

All tubular skylights consist of 4 major components:

Skylight Warranty – It Is All In The Tube!

  • The Dome on the roof to collect the light for the skylight.
  • The Roof Flashing that the dome is attached to. The flashing is also attached to the roof and creates a watertight seal for the skylight.
  • The Tube that reflects the collected light down the skylight.
  • The Diffusor (or lens) in the ceiling of the room to deliver and spread the light through the room.

MaxLight Tubes Vs Laminated Tubes

Why is there this major difference in warranties between skylight brands? The answer is all in the skylight tube. Specifically laminated tubes vs the MaxLight highly polished aluminum tube.

The tubes in tubular skylights need to be highly reflective to effectively “beam” sunshine light down the tube through your roof to brighten the room they are installed in. While most skylight brands use laminated tubes, MaxLight skylights use an aluminium tube with a super reflective anodised surface inside the tube to reflect the light through.

Skylight Warranty – It Is All In The Tube!MaxLight Tubular Skylights In a Dining Area

The tubes in laminated skylights are made of aluminium, just like the MaxLight tube – however there is one critical difference. On the inside of the tube they have a laminated plastic reflective coating applied to increase the light reflectivity of the tube. This reflective coating initially offers a small gain in light reflectivity, however from the day of installation the laminated reflective coating begins to deteriorate.

With continued exposure to the ultra-violet rays in sunlight this plastic laminated coating degrades, and the skylight begins to reflect less light into the room. The coating can also delaminate, peeling away from the aluminium tube altogether. This has a major effect on the skylight performance, decreasing the reflectivity of the tube which effects the amount of light coming through to the room.

With MaxLight skylights there is zero chance of delamination as there is no plastic laminated coating. The anodised tube performance does not suffer any damage from the UV light in sunshine. The tube has a reflectivity rating of 98% and performs over its 20-year warranted life time with only minimal degradation.

The benefits to the customer? Peace of mind with double the warranty. You get better performance over time with none of the degradation that happens with a laminated coating on the tube. Who would have thought that some skylight tubes degrade with exposure to the light they are designed to bring into your home?

Well, that’s why they only have a 10-year warranty!
