In essence, toughened glass isn’t just an upgrade in durability; it’s a safeguard for both structure and occupants. By fusing cost-effectiveness with safety, it exemplifies a synergy that underpins the ethos of architectural innovation. Roofglaze’s dedication to quality and assurance ensures that each pane of toughened glass is not just a component, but a testament to our unwavering commitment to excellence.

Laminated Glass

Consisting of two or more layers of glass with an interlayer of plastic (PVB or SGP) in between, it’s a safer alternative to toughened glass for overhead glazing. When laminated glass breaks, the broken glass fragments remain held in-place by the PVB, drastically reducing the likelihood of falling fragments causing injury to those below. The glass also retains much of its structural strength when broken, and the types and thicknesses of the interlayer can be adjusted to suit any glazing requirement. For added structural strength an Ionomer or Sentry interlayer can be used. This layer is much stiffer and more robust than PVB. In addition laminated glass can incorporate acoustic interlayers that reduce the passage of traffic or other external sounds. The levels of decibel reduction can be tailored to suit any project.

Laminated glass presents a compelling alternative to toughened glass for overhead glazing, boasting enhanced safety features that redefine the standard. Comprising multiple layers of glass enveloping an interlayer of plastic, be it PVB or SGP, this innovative configuration is engineered to prioritize safety and structural integrity.

In the event of breakage, the interlayer assumes a crucial role – securely binding the shattered glass fragments, thereby mitigating the risk of falling debris and potential injuries. The glass itself retains a considerable degree of its structural strength even in its broken state, a testament to the resilience of this design.

Customization lies at the heart of laminated glass’s prowess. The interlayer, whether PVB, SGP, Ionomer, or Sentry, can be tailored to align with specific project requirements, tailoring the glass’s characteristics to match diverse glazing demands. Structural reinforcement finds its champion in the Ionomer or Sentry interlayer, which bestows added robustness to the glass composition.

Laminated glass’s versatility extends beyond safety and structural integrity. Acoustic interlayers can be integrated, orchestrating a harmonious symphony of tranquility within the enclosed space. By curbing the ingress of external sounds, the ambience within can be finely calibrated to cater to the specific needs of each project.

In essence, laminated glass represents a leap forward in the realm of overhead glazing, where safety, strength, and versatility converge. Beyond its utilitarian attributes, it stands as a testament to the constant evolution of architectural materials, culminating in a solution that not only safeguards but elevates the experience of the built environment.

Frosted or obscure glass

Have a matte opaque finish that disperses light, making it a common choice for rooflights in bathrooms or other spaces where privacy is necessary.

Matte opaque glass presents a transformative solution that delicately balances aesthetics with privacy needs. Its distinctive finish, characterized by a gentle opaqueness, serves as a versatile choice for a spectrum of applications, with a particular affinity for rooflights in spaces where discretion is paramount.

The magic of matte opaque glass lies in its ability to scatter and diffuse light, rendering it a natural selection for areas that require both illumination and seclusion. Bathrooms, in particular, find themselves transformed by the embrace of this glass variant, where the play of light takes on a softened, ethereal quality, while ensuring an intimate atmosphere that preserves personal space.

Its versatility extends beyond bathrooms, finding resonance in any environment where the interplay of light and privacy converge. This glass variant transcends functionality, morphing into a canvas for design expression that harmonizes with the broader architectural narrative.

In essence, matte opaque glass is a dance between light and privacy, orchestrating an ambiance that’s both visually captivating and purposeful. It embodies a delicate equilibrium, offering glimpses of illumination while shrouding the inner sanctum in an aura of seclusion. With each pane, it invites inhabitants to relish the harmony of form and function, where architectural ingenuity serves both practical needs and aesthetic aspirations.

Solar Control Glass

Intended to reflect a considerable amount of the sun’s heat away from the building, it reduces solar heat gain in the space below. Solar control coatings also include Low E so this combination reduces cooling expenses during the summer whilst still providing high levels of insulation in the winter months creating a space that can be enjoyed all year round.

Solar control coatings emerge as a strategic shield against the sun’s relentless heat, operating with the precision of a heat reflector to curtail solar heat gain within the space below. This calculated intervention translates into a tangible reduction in indoor temperatures, serving as a potent ally against the scorching grasp of summer.

Solar control coatings, however, wield a dual-edged functionality, encompassing the attributes of Low-E coatings. This dynamic pairing not only mitigates cooling expenses during sweltering summers but also accentuates insulation prowess during the frosty embrace of winter. This symphony of attributes orchestrates an environment that’s engineered for year-round enjoyment, effortlessly adapting to the seasonal whims of nature.

This pairing of solar control and Low E coatings isn’t just a technological synergy; it’s a blueprint for architectural harmony that prioritizes both comfort and energy efficiency. By harnessing the potency of solar control coatings, occupants are enveloped in an environment where the sun’s intensity is gracefully tamed, transforming spaces into havens of tranquility that transcend the seasons.

Rooflight sizes

When it comes to selecting a rooflight, there are various factors to consider. One of the primary considerations is the size of the rooflight, which can vary widely. For smaller areas such as bathrooms, hallways, or closets, rooflights are an ideal way to get natural light into these dimly lit areas.

On the other hand, for larger spaces such as living rooms, kitchens, and bedrooms rooflights can be a central feature of the design and benefit from larger more expansive sizes. These rooflights can provide a considerable amount of natural light, which reduces the use of artificial lighting during the day. Additionally, they can help to create a more open and airy feel in the space.

However, for areas that require significant natural light, such as commercial buildings, studios, or offices large rooflights are more suitable. These larger units can serve as an impressive visual feature in a building’s design while also providing ample natural light to the space.

While the size of the rooflight is an important consideration, it’s not the only one. Factors such as glazing material, frame material, and opening mechanism should also be taken into account when selecting a rooflight. Ultimately, the appropriate size of rooflight for your project will depend on the size of the space, the amount of natural light needed, the orientation of the building, building use and your budget. Therefore, it’s essential to consider all these factors before making a decision.

If you need further assistance, it’s best to consult with a Roofglaze professional who can help guide you through the process.

Rooflight Detail

When designing a rooflight for your building, it’s essential to consider the rooflight detail. This is to ensure that it’s weather-resistant, watertight, energy-efficient, aesthetically pleasing, and provides suitable ventilation if necessary. One vital part of the rooflight detail is flashing, which seals the gap between the rooflight and the roof structure to prevent water ingress. Therefore, the flashing must be designed to be watertight and weather-resistant to ensure effectiveness.

Another essential aspect to consider in the rooflight detail is weathering. This refers to the way a rooflight is designed to withstand the elements, such as wind, rain, and sun. A well-designed rooflight can withstand extreme weather conditions and prevent the accumulation of debris, ensuring its longevity. For peace of mind, all Roofglazes rooflight designs are rigorously weather tested at an accredited test house.

Insulation is also crucial for maintaining the building’s temperature and reducing energy costs. To achieve this goal and ensure occupant comfort, the insulation must be effective and energy-efficient. Our rooflights can be delivered with a thermally efficient Argon-filled cavity in the glass or an even more efficient Krypton fill. We also optionally provide a timber kerb; all are fully compliant with Approved Document Part L of the current Building Regulations.

Depending on the type of rooflight, ventilation may be a consideration. For instance, rooflights that open should allow for adequate ventilation while preventing rainwater from entering the building. This balancing act is crucial in achieving the need for fresh air with the protection of the interior.

Last but not least, aesthetics plays a significant role in designing a rooflight detail. By creating a seamless design that integrates the rooflight into the roof structure, you can create a cohesive look enhancing the building’s overall appeal.


In conclusion, rooflight detail is a critical component of rooflight design that requires meticulous consideration of various factors. These include flashing, weathering, insulation, ventilation, and aesthetics. A well-designed rooflight detail can enhance a building’s performance and appearance while creating a more comfortable living or working environment.
