Super Sealed units are Toughened Laminate Glass Specialists. Laminated glass is bonded by a Polyvinyl Butyral (or PVB) interlayer, ensuring it provides longer lasting security.

In the event of the glass breaking, it is held in place by the PVB interlayer. The interlayer keeps the layers of glass bonded together, even when broken, and its high strength prevents the glass from breaking up into larger sharper pieces.


A glass roof allows light to flood a space and can enhance the mood of the occupants within.
  • Whilst there are many visual and environmental benefits to a glass roof, there are also practical considerations such as ease of maintenance, the need to control solar radiation and safety. All panels in a glass roof must be a designated Safety Glass; either toughened or laminated.

  • In case of breakages and for safety, the internal panels of any overhead glazing should be laminated to prevent fragments of glass falling.

The glass used within roof assemblies can be single glazed if no thermal performance is needed. However, in cases where maintaining a consistent temperature is important, double or triple glazed units can be used.

Laminating Solar Control glass is also a popular glass solution for roofs as it both provides a strong G-Value and safety. Glass roofs or roof-lights are under direct sunlight during the day, a solar control coating will help reduce the amount of radiation entering the space below and will help control the comfort levels of the internal climate.

For privacy, translucent interlayers, painted borders or sandblasted glass can be incorporated to the structure to reduce visibility through the glass unit whilst maintaining large light transmission levels.

DuPont™ SentryGlas® interlayers help create lighter, safer, more structural glass that can stand up to greater loads and higher threat levels. Besides its strength, SentryGlas® retains its clarity – even after years of service. Unlike other interlayers this premium product is much less vulnerable to moisture exposure or the effects of yellowing which can appear over time. DuPont™ SentryGlas® interlayers help create lighter, safer, more structural glass that can stand up to greater loads and higher threat levels.


Glass balustrades add drama to a staircase, especially when glass treads are used.
  • Glass can be used independently as a frameless glass support or within a supporting framework to allow light to transfer between level changes on a staircase.

  • A frameless glass balustrade construction should be toughened or laminated, with two panels of Toughened (or tempered) Glass laminated together. Thus, making the construction not only structurally stronger than a single piece of Toughened Glass, but also preventing glass fragments falling onto the space below.

  • Glass can be cut and curved and manipulated to create different shapes and give the appearance of movement and fluidity to a glass balustrade.

For a stronger and safer frameless glass balustrade, we would recommend the use of a Sentry Interlayer within the balustrade construction. An interlayer such as SGP will create a robust balustrade that will remain in-tact in the event of a glass panel breakage.

A Sentry Interlayer on an external frameless balustrade will also increase the life longevity of the installation. Sentry Interlayers are much stronger and do not react to water giving greater life longevity to any external applications.

Specialist interlayers or decorative techniques can also be introduced to these elements for a unique design effect.

SentryGlas® interlayers meets society’s demand for higher security and protection too. As bullet proof and blast resistant glass is becoming mandatory in building projects, SentryGlas® interlayers meets today’s wider security needs. The SentryGlas® interlayer is five times stronger and up to 100 times stiffer than conventional laminating materials.

This industrially acclaimed and trusted product can only be supplied by certified manufacturers of which Super Sealed Units is one.


Super Sealed Units are able to laminate fabric interlayers into glass. The beauty of colour and texture are protected within the glass to provide an elegant finish.

The laminating process, provides for the opportunity to encapsulate a wide variety of metal meshes within the protective glass layers. The decorative and aesthetic qualities of this mesh, are preserved with the structural strength and practicality of glass, allowing for innovative design solutions.

This is an ideal product for use in structural, decorative and acoustic applications as the process allows for a wealth of possibilities for a wide range of applications including screens, partitions and cladding.

Laminating can be combined with other finishes such as sandblasting and painting to enhance your design and create one of the most creative architectural product

In the lamination process, as well as the PVB (polyvinyl butyl) or EVA (ethylene-vinyl acetate) interlayer, other materials such as coloured interlayers, fabrics, metal meshes and digital prints can be included, providing for a range of possibilities.

Laminating can also be combined with other decorative glass products and finishes such as kiln forming, sandblasting and colour coating to further enhance the design.
