Trade Supply Rooflights and Lanterns. Precision Glass Roofs, Built for the Trade

The Glideline collection of flat rooflights, lanterns, lean-to systems and eaves glazing offers complete flexibility for installers, developers, and architects looking to add modern, high-performance glazed features to homes and commercial projects.

These are not off-the-shelf roof systems. Every product is made in-house by Glideline, tailored to order, and backed by the reliable service you need to deliver great results on site. We support you before, during and after installation, without competing with you for sales.

Flat Rooflights – GRL System

The GRL flat rooflight is one of the slimmest fixed rooflights available to the trade. With sightlines as slim as 0–20mm and the option for double or triple glazing up to 44mm thick, this product maximises light, minimises framing, and delivers stunning aesthetics both inside and out.

Installers benefit from:

• Frameless glass-to-glass joints, for a clean finish with no bulky borders.

• Acoustic performance up to 41dB, ideal for city properties or high-spec projects.

• Weather resistance, with Class 4 air tightness and Class 7A water tightness.

• Made-to-measure manufacturing, with custom sizes up to 1800mm wide and any length.

• U-values as low as 1.0 W/m²K, helping you meet Part L and energy targets with confidence.

Whether installed as a single module or in a run of frameless panes, the GRL is easy to specify, detail, and fit. We offer full technical support, drawings, and fast quoting to help you secure jobs and meet tight build schedules.

Roof Lanterns – Glideline Aluminium Lantern

Our aluminium roof lantern is engineered for visual impact and long-term reliability. Designed to span up to 6m x 4m without additional rafters, this roof lantern makes a statement in large extensions, open-plan kitchens, and vaulted ceilings.

Key features for installers include:

• Pre-fabricated kit design, reducing time on site and simplifying logistics.

• Sculpted die-cast components, for flush junctions and hidden fixings.

• Thermally broken aluminium, delivering U-values from 1.2 W/m²K or 1.0 with upgraded glass.

• Bespoke sizes, single or dual colour finishes, and compatibility with solar control glass.

• Factory-assembled precision, with no cutting or guesswork required during installation.

• No visible fixings

We support our trade partners with accurate, consistent product quality—no warped frames, misaligned joints or silicone-heavy installations. Glideline lanterns give you a better product to install, and a better result for your client.

Lean-To Roofs – Frameless Lean-To Glazing

Our frameless lean-to roof system delivers a contemporary architectural finish, while maintaining full weather and thermal performance. With bonded glass-to-glass joints and minimal supporting framework, this product is perfect for kitchen extensions, side return infills, and rear projections.

Installer benefits:

• Unlimited panel runs, up to 1800mm wide with near-frameless spans.

• Fast, clean installation, with fewer parts and precise construction.

• U-values down to 1.0 W/m²K, supporting SAP calculations and compliance.

This product eliminates the visual clutter of rafters or bolted joints, letting you offer your customers a roof solution that’s as modern and seamless as their new interior.

Frameless Eaves Rooflight – Glideline Integrated Eaves

The Glideline Frameless Eaves Rooflight offers a fully bonded roof-to-wall glazed connection, transforming flat roof builds with a sense of height, light, and luxury. This is a product few suppliers offer—and even fewer can fabricate at our level of quality.

Frequently Asked Questions

What’s the difference between a roof lantern and a rooflight?

A: A roof lantern is a raised, pitched glazed structure often used in large flat roof extensions. A rooflight (or flat rooflight) sits flush with the roof and offers a frameless look with light from above. Both are available from Glideline.

Can I get matching finishes across all Glideline products?

A: Absolutely. All our products—including patio doors, windows and roofs—can be colour matched and use compatible sightlines for a fully coordinated installation.

Q: Are the products available with self-cleaning or solar control glass?

A Yes. All roof products can be upgraded with solar control, self-cleaning, privacy or acoustic glass depending on your project requirements. Safety glass comes as standard throughout.

How are Glideline products delivered?

We offer nationwide delivery direct to site, with all units made to order in our facility. You’ll receive a complete product, ready for fast installation.

Can Glideline roof products be installed in commercial properties?

Yes. Our systems are suitable for both residential and commercial use. We support developers and architects with specifications, samples, and layout support for larger projects.
