Laminated Safety Glass

The exterior glass used in all PLANAR systems is normally 6mm or 8mm tickness Float tempered and heat soaked glass that can be either clear or tinted.

All glass complies with international standarts 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.

LAMGLAS Skytec® 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 Skytec® laminated glass is manufactured by cureable 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.

Notes

All 4 or 6mm glasses 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. A wide range of glass combinations is possible with laminated glasses.

Specification- Single LAMGLAS Skytec® Laminated Safety Glass

Composition

Thickest glass will be to single LAMGLAS Skytec® standard and reference should be made to single LAMGLAS Skytec® specification.

Glass combinations

10mm + 6mm or 4mm

12mm + 6mm or 4mm

15mm + 6mm or 4mm

LAMGLAS Skytec® Laminated Safety Glass

Interlayer: 1mm, 1.50mm or 2mm

There may be a step up on each side to 3mm

Overall thickness: +/-1mm tolerance

 

Glass size- rectangles

Maximum (4mm):	1500 x 2500mm	-0 + 4mm
Maximum (6mm):	2000 x 3900mm	-0 + 4mm
Minimum:	400 x 700mm	-0 + 4mm
Aspect ratio:	2:1 Maximum for larger sizes

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.

Position:	Normally 100mm from glass edge at corners and sometimes along edge. Other configurations subject to confirmation
Tolerance:	2+/-2mm from one datum point.

Method of production

Cast-in-place

Tempering

10/12/15/19mm glass: Toughened and Heat Soak tested avaible 4/6mm glass: Heat Strengthened

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. Multiple panes will not necessarily be marked in the same corner.

Visual quality

Clear tape

The cast-in-place process uses a clear tape 6 to 9mm wide around the edge and around the holes between the two glasses. The junction between the clear tape and the resin is just visible inboard from the edge of the glass and the holes.

Bubble

As with lamination techniques there will be minor imperfections as follows: Very fine bubble at resin/tape interface. One bubble of size 2-3mm will be acceptable per m run or per hole area. One bubble of size 2-3mm will be acceptable in the body of each plate but not in the visible area as defined by an oval touching the centre of all four sides.

Distortion

When laminating toughened or heat strengthened glasses together slight visible distortion in transmission due to the small lens effects 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. Site inspection should be from a distance of 3m.
