The VELUX Group vs RoofLITE+

February 2026

When choosing a roof window, two names often come up:

• VELUX GGL 2070

• RoofLITE+ AAY B910

At first glance, they appear very similar.

• Both are white painted, centre pivot roof windows.

• Both offer strong thermal performance.

• Both are manufactured within the same wider corporate group.

Yet one is positioned as a premium product, and the other as a high-quality, more affordable alternative. Understanding why requires looking at both the brands and the specifications.

The Brands: Shared Manufacturing Heritage

The VELUX Group has been a global leader in roof window manufacturing since 1941. VELUX is known for:

• Long-standing brand heritage

• Extensive product development

• Wide accessory compatibility

• Strong safety credentials

• Premium market positioning

Over decades, VELUX has built significant brand recognition in both residential and trade markets. That reputation plays a role in how its products are positioned and priced.

RoofLITE+ is part of the VKR Group, the same international group behind VELUX. This means RoofLITE+ benefits from:

• Established manufacturing expertise

• Proven roof window engineering

• Group-level quality standards

However, RoofLITE+ is positioned differently in the market. Rather than focusing on brand legacy and an extensive accessory ecosystem, RoofLITE+ concentrates on delivering:

• Core performance

• Strong thermal efficiency

• Clean, modern design

• Accessible pricing

Comparing the Products: GGL 2070 vs AAY B910

1. Glazing & Safety

VELUX GGL 2070

• Laminated inner safety pane (--70 glazing)

• Toughened outer pane

• Designed for above-head-height installations

• Laminated glass holds together if impacted

This makes it particularly attractive where enhanced internal safety glazing is a priority.

RoofLITE+ AAY B910

• Energy-efficient double glazing

• Toughened outer pane

• U-value as low as 1.3 W/m²K

The focus is strong thermal insulation combined with durability and weather resistance.

2. Thermal Performance

Both windows are designed to reduce heat loss and improve indoor comfort.

• RoofLITE+ AAY B910: U-value as low as 1.3 W/m²K

• VELUX GGL 2070: Comfort glazing engineered for improved insulation and indoor climate control

In practical terms, both offer excellent performance when correctly installed with the appropriate flashing kit.

3. Finish & Aesthetic

Both models feature a white painted internal timber finish designed to:

• Reflect more natural light

• Brighten loft spaces

• Complement modern and traditional interiors

VELUX adds:

• Pre-assembly painted finish

• Anti-fungal treatment

• Subtle visible wood grain texture

RoofLITE+ offers:

• Smooth contemporary white finish

• Clean, modern aesthetic

• Durable painted timber construction

The Key Difference: Market Positioning & Price. This is where the most noticeable difference appears.

VELUX GGL 2070 - Premium Positioning

VELUX products typically sit at a higher price point. This reflects:

• Brand heritage and global recognition

• Investment in marketing and product development

• Expanded accessory systems

• Laminated inner glazing as standard in this model

Customers are often paying not only for the product specification, but also for brand reputation and long-established market leadership.

RoofLITE+ AAY B910 - Affordable Quality

RoofLITE+ is positioned as a high-quality but more accessible alternative. Because it operates with a more streamlined product range and a different brand strategy, it is generally available at a significantly lower price point than equivalent VELUX models.

Importantly:

• Lower price does not mean low quality.

• Being part of the VKR Group ensures:

• Robust manufacturing standards

• Reliable engineering

• Consistent product performance

For many homeowners and developers, RoofLITE+ offers an appealing balance of:

• Strong energy efficiency

• Durable construction

• Modern design

• More budget-conscious pricing

This makes it particularly attractive for:

• Multi-window loft conversions

• New-build developments

• Projects with strict budget parameters

• Replacements where premium glazing upgrades aren’t required

Which Should You Choose?

Final Thoughts

The comparison between the VELUX GGL 2070 and the RoofLITE+ AAY B910 is not about one being “better” than the other.

It is about:

• Premium brand positioning vs affordable quality

• Laminated safety glazing vs standard energy-efficient double glazing

• Brand legacy vs value-focused engineering

Because both brands sit within the VKR Group, they share manufacturing expertise, but serve slightly different segments of the market.

Understanding those differences helps you make a confident, informed decision for your project, whether you prioritise brand heritage or high-quality performance at a more accessible price point.
