Head Isolated Laminated Glass Panels
Heat-isolated Laminated Glass
The exterior glass used in all PLANAR systems is normally 6mm or 8mm thick tempered and heat soaked glass that can be either clear or tinted.
All glass complies with internatinal standart All glass, after tempering must pass a destructive quality control test, the heat soak. This test is designed to virtually eliminate spontaneous on site breakage of glass due to the possible presence of nickel sulfide.
Lamglas able to manufacturing all glass into a structural application which costumer prefered has heat soak. Heat soaking is a prudent investment in safety for all those concerned about liability on a project.
LAMINATED GLASS — Where laminated glass is required, especially in roof or layback glazing applications, 5/32" or 1/4" lites of the 
laminated unit will be supplied as heat strengthened to maintain greater panel integrity in the event of breakage.
LAMGLAS PLANAR laminated glass is manufactured by pouring a liquid resin between parallel glass panes held apart by a clear tape. The cast-in-place resin (CIP) can further improve environmental performance of the laminated unit by offering choices of excellent sound insulation, UV protection or light diffusion. The resin can be tailored to suit individual requirements such as a high level of acoustic performance and a very high level of UV protection. CIP resins allow the laminated unit to have an exposed edge to the weather and are compatible with accepted structural silicones.
LAMGLAS Skytec® PLANAR double glazing units normally have an outer lite of 6mm or 8mm thick glass. The units have a 16mm airspace which is the optimum for thermal insulation. Laminated glass can be incorporated into the Skytec glass unit.
The combination of glass types and thickness vary. Low emissivity glass as well as inert Argon filled units can be used to increase thermal performance.
To facilitate the positioning of the PLANAR fixing in the insulating unit a transparent boss acts as a separator between the two plates of glass. This in combination with newly designed clear bushes and spacers is now a standard feature in all PLANAR systems and provides clarity of vision greater than that achieved in the past.
Notes
All glasses used in the laminated pane are heat strengthened. A special acoustic laminate interlayer is used to give excellent noise reduction performances. Special UV laminate interlayers are also available to provide exceptional UV protection. All laminated glass edges are sealed to give excellent weather resistance. Silicone perimeter seals must be compatible with LAMGLAS Laminated Safety Glass.
An exceptionally wide range of glass combinations is possible with laminated double glazed units. Please refer to LAMGLAS website : http://www.lamglas.com
Specification- Single LAMGLAS Skytec® Heat-Isolated Laminated Glass Units
Composition
LAMGLAS Skytec® Heat-isolated Laminated glass Units are manufactured from one thick outer toughened glass which in roof glazing is usually to the outside and one laminated inner glass composed of two 4mm or two 6mm glasses and reference should be made to both single LAMGLAS Planar and single laminated LAMGLAS Planar specifications.

Shape capability
Rectangles and simple shapes. All tolerance will vary depending on the complexity of shape.
Edge condition
Smooth ground edges giving a flat profile with small ground arris. Shells or chips at edges will be ground out prior to toughening and do not constitute reason for rejection. Corners may be dubbed. Some variation in edgework may be discernible on exposed edges where different machines and/or hand forming is a requirement for manufacture. Such variations shall be kept to a minimum. Where the detail of a structure is such that the double glazing edge sealant is fully exposed, minor undulations in the edge seal may be discernable particularly near corners of the unit.

Glass marking
Glass will be marked with the LAMGLAS Skytec® toughening stamp and any other regulatory requirements. The mark to be on each glass usually near a corner.
Visual quality
Distortion
When laminating toughened or heat strengthened glasses together slight visible distortion in transmission due to the small lens effect will be noted with increase in viewing angle. The phenomenon is not normally a problem in roof glazing, but may be discernible in vertical glazing. The air in all sealed units expands and contracts in hot and cold weather causing the glass to bow out and in respectively and again reflections will reflect this movement. The clear tape around the edge will, or course, be totally within the edge detail of the sealed unit. Site inspection should be from a distance of 3m.
