Architectural Daylighting & Rooflight Solutions
As a specialist designer, fabricator and installer of glass atria and roof glazing systems, Structura UK delivers high-performance architectural rooflights and glazed atrium solutions that combine daylight, aesthetics and structural integrity. Whether you’re refurbishing an existing roof structure or specifying a new glazed feature, we bring decades of expertise in design, engineering and installation for commercial, heritage and landmark buildings.
Atria and roof glazing are increasingly important in modern building design, creating bright, inviting internal environments, improving energy performance and elevating architectural impact. Structura UK supports project teams at every stage, from technical specification to installation and aftercare.
What Are Atria & Roof Glazing Systems?
An atrium, in architectural terms, is a large open internal space, typically covered overhead by a glazed roof or series of rooflights. Modern atria flood interiors with natural daylight while enhancing visual connectivity within a building.
Roof glazing refers to glass or glazed panels installed on sloping or flat roofs to allow light into internal spaces while protecting against weather and providing thermal performance. Roof glazing can be part of an atrium roof, individual rooflights, or fully integrated bespoke glazing systems.
Structura UK’s atria and roof glazing systems are engineered to meet architectural design ambitions without compromising performance, durability or compliance.
How It Works
We’ve developed a clear, technically robust process that ensures your glazing project is delivered efficiently, safely, and to specification:
1. Initial Project Consultation
We begin by discussing design goals, site constraints, daylighting performance expectations, weather exposure and regulatory requirements.
2. Detailed Site Survey & Structural Assessment
A measured survey and structural review inform design parameters — including roof pitch, support frames and interface with existing structures.
3. Design & Specification Development
Our technical team produces detailed CAD/BIM drawings, selects glazing types (e.g. double or triple glazed rooflights) and aligns specifications with thermal and safety standards.
4. Engineering & Material Selection
Glazing panels, frames and structural support elements are engineered for load, weather and performance. Options include thermally broken aluminium framing and laminated safety glass.
5. Fabrication & Quality Control
Components are fabricated by Structura UK or partners according to precise manufacturing tolerances, with comprehensive QA and ISO-aligned systems in place.
6. On-Site Installation
We coordinate installation with contractors, ensuring safe roof access, weather management, structural integration and sealing to prevent water ingress.
7. Performance Testing & Handover
Completed installations undergo airtightness and water tightness reviews, documentation is provided, and operational guidance is shared with facility teams.

Bespoke Solutions for Design & Daylighting
We engineer roof glazing and atrium solutions to optimise natural light, improve internal comfort and integrate into architectural visions, from minimal rooflights to complex glazed atria.
Heritage & Retrofit Expertise
Many projects involving atria and roof glazing are refurbishments of existing structures. We specialise in sensitive retrofit works that balance performance requirements with architectural preservation.
Specifications & Standards
Our atria and roof glazing systems are designed and engineered in compliance with robust UK and European benchmarks:
Design Integration
Integration with structural elements such as steel or aluminium support frames ensures maximum spans with minimal obstruction and optimal daylighting without compromising structural integrity.
Material & Component Standards
Thermally Broken Aluminium Frames
Provide enhanced thermal insulation and minimise heat loss.
Laminated Safety Glass Panels
Ensure fragments remain bonded upon breakage, critical in roof glazing or atria.
Building Performance & Safety Standards
UK Building Regulations
Rooflights and glazed atria must comply with structural and safety regulations, including protection from impact and adequate fixing.
Thermal & Energy Standards
Glazed systems are specified with appropriate U-values to achieve or exceed Part L performance targets.
Safety Glazing Requirements
Laminated or toughened glass configurations are chosen to meet safety obligations under Approved Document K for overhead glazing.

Frequently Asked Questions
What is the difference between roof glazing and atrium glazing?
Roof glazing refers to glazed elements integrated into a roof structure, while atrium glazing typically describes glazed roofs spanning internal courtyard spaces or large central zones. Both deliver daylight and architectural presence.
Can glazed atria improve building energy performance?
Yes. Through daylighting and high-performance glazing specifications (e.g., low-U values), roof glazing can reduce reliance on artificial lighting and improve thermal comfort.
Are roof glazed systems safe for commercial buildings?
Roof glazing systems are engineered with laminated safety glass and robust support frames to meet regulatory safety requirements.
What materials are typically used in atria glazing?
Thermally broken aluminium frames and laminated or toughened glass are commonly specified for durability, insulation and safety.
Can atrium systems be bespoke designed?
Absolutely. Bespoke configurations can be engineered for specific spans, shapes, aesthetic goals and daylighting strategies.
Do you offer aftercare for roof glazing systems?
Yes, Structura UK provides planned maintenance and support services for long-term performance and compliance.
What are the main benefits of glazed atria?
Glazed atria bring in natural daylight, improve occupant wellbeing, create focal architectural features and can reduce lighting energy demand.
