A Trade Guide to the Stratus Flat Skylight

Summary

For the modern installer, the market for flat roof extensions is increasingly defined by minimalist aesthetics and non-negotiable thermal performance. Clients demand unobstructed views of the sky, seamless design, and exceptional energy efficiency. Our guide explores the rise of the flat glass rooflight and provides a detailed trade focus on the Stratus Flat Skylight. We cover its core benefits for installers, from its robust, thermally broken aluminium structure to its ease of installation, highlighting why it represents a superior, reliable, and profitable choice for your business.

The New Standard in Architectural Glazing

The single-storey extension has evolved. It is no longer a simple box added to the rear of a property; it is an architectural statement. As an installer, you are at the sharp end of this trend, tasked with delivering spaces that are not only functional but also aspirational. The key to achieving this is natural light, and the methods for inviting it indoors have become more sophisticated. The Stratus Flat Skylight is rapidly becoming the product of choice for discerning projects.

The market for lanterns & skylights continues to expand, but the demand for flat glass rooflights, in particular, has seen remarkable growth. Driven by minimalist design trends, these products offer a clean, contemporary alternative to traditional pitched lanterns, creating a pure ‘window to the sky’. For installers, this trend presents both an opportunity and a challenge: the opportunity to fit premium products, and the challenge of ensuring they perform flawlessly.

What is Driving the Demand for Flat Glass Rooflights?

To supply the right product, it is essential to understand the client’s objective. The demand for flat glass rooflights is primarily driven by three factors:

1. Minimalist Aesthetics: The “frameless” or “invisible” look is highly sought after. Clients want to see the sky, not the structure. A flat skylight sits low on the kerb, offering a discreet, clean finish that complements modern architecture.
2. Unobstructed Views: Unlike a pitched lantern, which has structural hips and bars, a flat skylight provides a single, uninterrupted glazed area. This “edge-to-edge” glass effect is a powerful selling point.
3. Versatility: Flat skylights are perfectly suited to the geometry of modern extensions, new builds, and refurbishments. They can be used as a single feature or in a series to create a dramatic, light-filled corridor.

Beyond Aesthetics: What Should Installers Prioritise in a Flat Skylight?

While the client may focus on the view, your reputation rests on the product’s performance. A poorly specified flat skylight can be a costly source of callbacks. Therefore, experienced installers must prioritise three technical aspects above all else: thermal performance, weather-tightness, and ease of installation.

Why is Thermal Performance Non-Negotiable?

You are fitting products in an era defined by Part L of the Building Regulations. Heat loss is a critical calculation, and the roof is a primary area of concern.

• U-Values: A flat skylight must have a low U-value (measuring the rate of heat transfer) for the whole unit, not just the glass. This is where budget products fail. A high-quality skylight features a fully thermally broken frame to prevent the aluminium elements from conducting cold from the outside to the inside.
• Condensation Risk: Cold bridging, a direct result of poor thermal breaking, is the leading cause of internal condensation on the frame. This can lead to cosmetic damage and a dissatisfied customer.
• Compliance and Comfort: Specifying a high-performance unit, such as the Stratus Flat Skylight, ensures you meet and exceed regulatory requirements, delivering a comfortable, draught-free space for the end-user.

How Does Frame Design Impact Longevity?

The integrity of the entire installation depends on the design of the frame. The materials and engineering must be robust enough to withstand decades of British weather.

• Material: Aluminium is the optimal choice. It provides the strength and rigidity to support large glass units while remaining slim and lightweight. Its inherent corrosion resistance ensures a long, maintenance-free life.
• Weather-Tightness: The bond between the glass and the frame is critical. Look for factory-bonded units where possible. The design must ensure water sheds efficiently without pooling or testing seals.
• Structural Integrity: The frame must handle wind and snow loads without deflection, which could compromise the seals or the glass itself.

• Sleek, Minimalist Frame: The slim, unobtrusive aluminium frame is the definition of modern minimalism. Available in stock Anthracite Grey or Jet Black, it provides a subtle, contemporary finish that maximises the glass area.
• Optimised ‘Edge-to-Edge’ Glass: The unique design conceals the frame, providing a stunning ‘edge-to-edge’ glass finish from the inside. This delivers the unobstructed “sky-only” view that clients demand.
• Uncompromising Security: Peace of mind is built in. The laminated inner glass pane is standard, ensuring that even if the glass were to break, it would hold in place, enhancing the security and safety of the property.

When Should You Recommend a Flat Skylight Over a Lantern?

As a trusted installer, your advice is key. The choice between a flat skylight and a lantern often comes down to the project’s architectural style.

Recommend a Flat Skylight (like Stratus) when:

• The client’s primary desire is a minimalist, contemporary, or ‘invisible’ look.
• The ceiling below is flat, and the goal is a pure, clean view of the sky.
• The property’s architecture is modern, and a traditional pitched element would look out of place.
• The roof area is overlooked, and a low-profile solution is required.

Recommend a Lantern (like the Stratus Aluminium Lantern) when:

• The client wants to create a sense of height, volume, and grandeur in the room.
• The lantern itself is intended to be an architectural feature, drawing the eye upwards.
• The property has a more traditional character that benefits from a pitched roof element.
