Commonly referred to as a “SIGU”, Sealed Insulated Glass Unit’s are the most effective way to reduce air-to-air thermal transfer through the glazing.
When used in conjunction with low emissivity and/or reflective glass coatings, SIGU’s become an effective means by which to conserve energy and comply with energy regulations. Low-emissivity coatings have gradually become better at reducing air-to-air heat transfer, and spacer technology has become the focus of incremental thermal improvements. Our bendable spacer bar (6 to 20mm thickness) is composed of formed aluminium filled with molecular sieve to absorb any residual moisture inside the SIGU, thus reducing the potential for condensation to form.
Our SIGU’s comprise of a primary seal (PIB) and a secondary seal using Polyurethane or Silicone. All SIGU’s are fitted with a capillary tube which allows pressure inside the unit to equalize with atmospheric pressure by allowing air to flow in and out of the unit. While the spacer bar is a structurally strong material, the aluminium to glass contact point is a very efficient thermal conductor and can increase the potential for temperature differential between the centre of glass and the edge of glass, which can lead to condensation and reduce the overall thermal insulation (U-value) of the window.
Efficiency
Typical issues affecting energy efficiency include orientation towards north, window sizing and positioning, shading, choice of materials with regards to thermal and insulation properties, solar heating, natural cooling and day lighting.
Light
Lighting now also needs to be specified, taking in consideration light levels, energy demand and energy consumption.
Heat
Heat loss in winter and overheating in summer represent a major portion of the heating and air-conditioning (AC) load, contributing significantly to the cost of operating a building.
Glass attracts immediate attention to almost any building, and if we acknowledge that glass often defines a structure’s character, it’s not all about aesthetics because the potential energy loss associated with it is a major concern for designers and owners.
Heat loss in winter and overheating in summer represent a major portion of the heating and air-conditioning (AC) load, contributing significantly to the cost of operating a building. By trapping a layer of dried air between two sheets of glass (prevent convection currents from forming) we achieve a superior insulating medium, which is improved if we introduce Low E glass (Which also reduces the emission of radiant solar energy from a warm surface to a cold body or room).
Under standard conditions the insulation value of the double glazing with Low E is reduced by 67% in winter and 64% in summer when compared to ordinary 6.38mm laminated glass.

Phoenix Lam
Fully tempered/toughened glass is four to five stronger than annealed glass of the same type and thickness and meets break-safe requirements for safety glazing.
Fully tempered glass, when broken, fractures into hundreds of small blunt particles and this is by design and is excellent proof of a well-tempered product, not of a defective product.
It is this fail-safe characteristic of tempered glass that makes it an excellent product for safety glazing applications. Annealed glass is easily broken by mechanical stress, impact, and moderate thermal stress.
PhoenixTough fully tempered glass will withstand much greater stresses than annealed glass before failure.
However, it is the nature of fully tempered glass that it CANNOT break in the simple fashion of annealed glass but the entire panel must “release” completely into small fragments even for a very small initial fracture. Available in different thicknesses and colours.
Typical applications
- Frameless Showers & Doors
- Bolted Structural Glazing
- Double Glazed Units
- Armour Laminates
- Ovens & Fridges
- Balustrades
- Table Tops
- Pool fencing
Benefits and Features
- Resistance to thermal stress
- Enhanced strength
- Windload attributes
Phoenix ToughLam
this product combines the strength and features of PhoenixTough with the added safety features of a laminated product in so far as providing safety, security, solar control, sound dampening features and bolted assembly’s.
When using toughened safety glass in the configuration the laminate is able to remain intact after breakage because it holds the glass shards together, coupled to displaying enhanced protection from a human impact point of view. This product can and should be recommended over the use of fully tempered panels (depending on the glazing application and or safety concerns)
This advanced technology delivers extreme glazing performance, durability and reliability. In extreme conditions – hot or cold Phoenix Armour Laminates perform consistently.
Typical applications
- Balustrades
- Fins
- Floor sprung doors
- Stairtreads/bolted assembly
- Rim flows
Benefits and Features
- Thermal Resistance
- Containment after fracture
- Strength
- Safety
- Solar Performance
- UV Resistance
