Introduction HansenGlass is at the forefront in the design and manufacture of painted and decorated fritted glass panels. Ceramalite™ is a high quality enamelled toughened glass, available in a range of standard colours, designed for use in the spandrel areas of curtain wall. Ceramalite™ can also be utilised as a wall cladding product in shower areas and kitchen back splashes. Ceraphic™ screen printed toughened glass, is available in a range of standard colours and patterns. It can be used both internally and externally to create striking designs, corporate logos and images, solar control and safety manifestations.

CeraGrit™ is a product that gives enhanced anti-slip characteristics to toughened glass when utilised in flooring, stair treads or landing panels. CeraGrit™ can be applied to either a dot or line pattern.

Cerocco sandblasting can be applied to either annealed or toughened glass to create areas of obscuration or defined patterns. A clear water repelling treatment can be applied after sandblasting to reduce cleaning and maintenance.

PolyLite™ edge lighting utilises the latest LED and fibre optic lighting technology coupled with an embedded pattern on the glass surface to create stunning visual effects. PolyLite™ is ideal for applications such as partitioning, balustrading, shower screens and lift cars. HansenGlass products can incorporate multiple decorative processes from the above range of products. Advantages • total obscuration of internal structure or services • capable of creating a wide range of visual effects • aids solar control • available in a wide range of standard and non-

standard colours • highly durable against abrasion, corrosion and

chemicals • minimal maintenance • no fading • impervious to discoloration by internal deposits • choice of insulation to suit performance

requirements • has a wide range of internal finishes • single and double glazed options • thermally safe • can be used for decoration • available as a heat soaked toughened glass Product Description Ceramalite™ is available in thicknesses from 6mm to 15mm as single glazing or as the inner pane of a ThermoCool™ insulating glass unit, where it can be combined with a variety of outer panes. Both versions can be supplied with an integral insulation backing, in the form of either: • foam, covered with aluminium foil • an aluminium tray, with a variety of surface finishes, containing mineral fibre or foam; or • fire retardant type insulation The U value of the insulated Ceramalite™ products can be as low as 0.2 W/m2K. Ceramalite™ is manufactured by roller coating the glass - already prepared complete with any edge working, shaping, holes and cutouts - with a water based enamelling paint. The paint is oven dried and the glass is then subjected to a heating and cooling cycle, during which the enamel paint is fired into the glass surface and the glass is toughened. When used as spandrel panels, the Ceramalite™ can be used either as a single glass or in ThermoCool™. The enamelled surface is normally glazed on surface 2 (counting surfaces from the external surface of the building) for single glazing or on surfaces 2 or 4 of ThermoCool™.

Ceraphic™ is available in thicknesses from 6mm to 25mm as single glazing or as part of a ThermoCool™ insulating glass unit.

Ceraphic™ is manufactured by screen printing - using a squeegee to deposit ceramic ink through a cloth mesh, which may be masked to form a pattern of ink. The ink is oven dried and the glass is then subjected to a heating and cooling cycle, during which the enamel ink is fired into the glass surface and the glass is toughened.

Ceraphic™ can be used to create striking visual effects for decorative, safety, obscuration and solar control purposes. HansenGlass offer a range of standard patterns and standard colours and can assist in the development of designs and colours in line with the customer’s specific requirements. CeraGrit™ is manufactured in the same way as Ceraphic™, except that a grit material, which does not subsequently melt when the enamel is fired into the glass, is added to the screen printing ink. The CeraGritTM product not only offers enhanced anti-slip characteristics but, by utilising the screen printing process, dot matrix or line patterns can provide an aesthetic appearance in different colours.

Cerocco sandblasting can be applied to give 100% surface coverage or masked to specific customer requirements. Cerocco offers obscuration for privacy and security but can also act as a manifestation for safety. PolyLiteTM edge lighting utilises low iron FortPlusTM toughened glass with an embedded surface pattern to aid the spread of light across the surface of the glass. By utilising LED and fibre optic technologies it is possible to create programmable lighting effects in different colours.

Product Performance Thermal insulation applied to Ceramalite™ All forms of Ceramalite™ can be supplied with insulation adhesively fixed to the inner surface. The options are: • foam with foil backing • mineral fibre or foam in an aluminium tray, either mill finished or polyester powder coated; or • fire retardant type insulation Some of the standard constructions are:

(i) (ii) (iii)

(i) single Ceramalite™ with stepped insulation for glazing directly into a single glazing rebate. (ii) single Ceramalite™ with stepped insulation and an aluminium channel to fit an insulating unit rebate. (iii) ThermoCool™ Ceramalite™ with stepped insulation.

Figure 1. Some standard insulated Ceramalite™ constructions

Foam insulation is available in a range of thicknesses. The foam may be bonded direct to the glass with an aluminium foil facing covering the foam, or housed in an aluminium tray which is bonded to the glass. Mineral fibre insulation can be supplied in 25, 50, 65, 75 and 100 mm thicknesses and the normal method of fixing is for it to be housed in an aluminium tray which is bonded to the glass. The thickness of insulation material required depends on the thermal insulation to be achieved.

There will be some slight colour variation within normal tolerances. It should be noted that where combinations of different glass thicknesses are used, some variation in colour might be seen, particularly with the lighter colours. A true white colour cannot be achieved due to the inherent pale green colour of glass. There are three standard Ceraphic™ colours: • 10% acid etch effect (which gives a similar appearance to sandblasting) • 20% white acid etch • Polar white There is one standard colour, graphite, for CeraGrit™. Other colours can be supplied, or specimen shades matched, subject to the limitation of the process.

The colours specified for non-standard Ceramalite™ and Ceraphic™ are assumed to be as viewed through the glass, unless clearly stated otherwise. The colours specified for non-standard CeraGrit™ are assumed to be as viewed from the printed side, unless clearly stated otherwise. There will be a minimum charge for the quantity of non-standard paint or ink required to run the process.

Appearance Ceramalite™ may have small pinholes and areas of differing density of the enamel. These should not be visually disturbing when the panels are viewed from the exterior of the building, in daylight, against an opaque background. Ceramalite™ is designed to be positioned in non-vision areas only and not where it may be viewed from inside the building against a bright sky, when the unavoidable irregularities and pinholes in the enamel finish may be evident. A special version, Ceramalite™Plus, can be supplied for use where viewed against bright light. This requirement should be clearly stated at the order stage so that it can be taken into account during production.

Ceraphic™ screen print is designed to be viewed from either surface. The printed surface has an eggshell, rather than gloss, finish. It may have a very small number of pinholes. The print may have slight variations in ink density parallel to the direction of draw of the squeegee blade. These are more obvious in large areas of print, especially when the glass is viewed against back-lighting. They are also more obvious in darker colours.



Ceraphic™ is available in a range of patterns, for example: - Micropoint 4 4mm printed points in a 5 spot pattern at 6.4mm centres giving 31% cover. Micropoint 6 6mm printed points in a 5 spot pattern at 8.5mm centres giving 39% cover. Micropoint Contour 4 4mm clear points in a 5 spot pattern at 6.4mm centres on a printed background giving 69% cover. Micropoint Contour 6 6 mm clear points in a 5 spot pattern at 8.5mm centres on a printed background giving 61% cover. Microline 5/5 and Microline 10/10 5mm printed lines with 5mm gaps or 10mm printed lines with 10mm gaps, both giving 50% cover. Microline 10/5 and Microline 5/10 10mm printed lines with 5mm clear lines giving 67% cover or 5mm printed lines with 10mm clear lines giving 33% cover. CeraGrit™ will have variations in the density of the grit coverage. This is obvious if the CeraGrit™ is printed in large areas. It is recommended that CeraGrit™ is printed in a dot pattern which makes the variation of grit coverage less apparent. Strength Ceramalite™, Ceraphic™, CeraGrit™ and PolyLite™ are four to five times stronger than ordinary glass of the same thickness. It has increased resistance to mechanical and thermal stresses. If broken it fragments into small relatively harmless pieces. For normal purposes, the allowable stress is:

Ceramalite™, Ceraphic™, CeraGrit™, Cerocco and PolyLite™ should be handledwith great care at all times. Correctly stacking and supporting of all glass products, in a manner whichprevents the glass from sagging, helps to avoid breakages. To prevent edgedamage, the glass must stand on strips of something softer than glass, such aswood or felt. Water must not be allowed to reach the edges of stacked glass as it can be drawnbetween the glass by capillary action and cause damage to the glass surfaces. Glass should be unpacked on arrival at site and checked for conformity tospecification. Any damage should be reported immediately. Use protective clothing and equipment (a minimum of gloves and safety glasses).Lift the glass in a safe manner using appropriate equipment. Note that glasssuckers are not appropriate for lifting CeraGrit™ on the gritted surface. Special care must be taken to protect Ceramalite™, Ceraphic™, CeraGrit™, Ceroccoand PolyLite™, especially the edges, from impact damage (knocks, abrasions andexcessive local pressure) which can cause breakage, scratches, scars, chips or shells. Before use, the glass should again be checked for damage and the size checkedwith the frame to ensure that the glazing can be carried out as specified.Damaged glass should not be glazed. Ceramalite™, Ceraphic™, CeraGrit™, Cerocco and PolyLite™ must be protectedfrom site contamination such as welding spatter, or cementitious or plasterproducts, or adhesives. Particular attention should be paid to protecting thesurface of CeraGrit™ from contamination as it may be difficult to remove.
