PANELS / P.

Made from shards of glass discarded during the manufacture of Brokis handblown glass lighting collections, Brokisglass has brought about a significant reduction in waste material. The transformation of these shards into a new decorative product represents an environmentally friendly and efficient upcycling of material, thanks to which the glassworks is able to employ a strategic circular economy and thus contribute to the creation of a healthy relationship between nature and humans.

Other sizes and thicknesses can be made to order. Smaller sizes and other formats and shapes are created by cutting individual panels with a waterjet.

Technical information

Nomenclature

Decorative BROKISGLASS panels are designated in the portfolio with the letter T – TILES.

Base variant

The base variant is flat material that we can subject to a fusing process to bend (curve) the glass according to customer requirements. The maximum angle of curvature is 120°.

Nominal dimensions The nominal dimensions of the panels are 700×700 mm. For a surcharge, the dimensions can be increased to a maximum of 1100×1100 mm.

Thickness Due to the manufacturing process, it is not possible to achieve precisely the same thickness across the entire panel. Thickness varies between 7–10 mm. We can custom manufacture panels with a maximum thickness of 30 mm. Thicknesses other than the standard 7–10 mm will incur a surcharge. The material has a maximum allowable variance of 2 mm.

Weight The weight of the standard 700×700 mm format is approximately 11 kg. Panels in the maximum possible dimensions (surcharge) weigh approximately 17.5 kg.

Colours The selection of colour options is based on the standard production of Janštejn Glassworks. Currently, there are 14 colours: 1 Triplex Opal BROKISGLASS (CGC2676), 2 smoke colours in combination with crystal (Smoke Grey Triplex Opal BROKISGLASS CGC2677 and Smoke Brown Triplex Opal BROKISGLASS CGC2705), and 11 colours in combination with Triplex Opal (white), see https://brokisglass.cz/brokisglass/. In the case of Light Pink Triplex Opal BROKISGLASS (CGC2722), the glass may display subtle tones of brown as a result of a slower onset of colour. For a surcharge, multiple colours can be combined within a single panel according to customer requirements.

Texture The texture varies from one piece to the next and depends on many factors, such as the fractions of the glass fragments, their orientation, dispersion, etc. BG is a special material, and each piece is a unique original. For a surcharge, customers can request a more compact texture in the material achieved by aligning the glass fragments in the piece.

Face finish Depends on use. Gloss and matte options are available.

Edge finish In the base variant, the edges are chamfered by hand, therefore the same angle cannot be declared along the entire length of the piece. The process softens the sharp edges left behind by the waterjet cutting process. The resulting appearance of the edges is matte as opposed to a polished finish. Limitation: holes cut in panel cannot be chamfered. Holes with a minimum diameter of 100 mm can be polished. Curved edges can be polished only when the curvature is 80°–100°.

Back side In the base variant, the back of the panels is sandblasted, leaving a matte finish. For a gloss finish and for safety reasons, a coating can be applied that acts as a safety film. In custom dimensions (up to 1000 mm), there is a visible joint on the back of the panel, but this has no negative effect on the properties of the material.

Material Upcycled glass from primary production of high-quality glass in Czechia with a tradition dating to 1809. No added ingredients. 100% safe, recyclable.

Applications

A wide range of uses in architecture and design. Consideration must be given to the unique properties and limitations of the glass. BROKISGLASS can be used as façade cladding, and in the interior it can fulfil the role of partitions, countertops, and shower stalls, and it can also be incorporated into interior fittings.

Bubbles in the glass

During the manufacturing process, air bubbles may appear in the glass. This is not a defect or a sign of reduced quality and therefore may not be the subject of a warranty claim. We never ship any product that does not meet our strict quality control standards. Such anomalies are unique trademarks of handmade glass, and the presence of up to 3 air bubbles 1.5–2 mm in size per segment with sealed surface is not grounds for a warranty claim.

Hairline cracks in the surface of the glass

When they appear at joints between individual fragments, they are not grounds for a warranty claim. Such cracks are superficial only and do not extend into the material, thus they have no effect on the declared properties of the material.

Visible waterjet entry point

The waterjet entry point takes the form of a subtle notch. This is entirely normal. The technology provides no way to prevent this during manufacture; however, the irregularity is minimized in subsequent operations.

Warning

BG is not intended for settings subject to rapid temperature fluctuations or high mechanical loads and may not be used in place of tempered glass. We do not guarantee the material’s properties if used incorrectly. Prior to use, always consult with our specialists to ensure the suitability of the installation.

Tempered Glass

Not at present; currently undergoing testing

Laminated glass

Not at present; currently undergoing testing

Bevel

A bevel can be created using a waterjet only in the case of flat panels and a straight trajectory at an angle of less than 45°.

Radius

Per customer requirements, the glass can, for a surcharge, be bent (curved) by means of fusing. The minimal angle of curvature is 120°.

Waterjet

Limitation – for safety reasons, the smallest dimension that can be cut out using a waterjet is 50 x 50 mm; minimum hole diameter 5 mm. Customers can request the cutting out of strips, but consideration must be given to their width and length to prevent cracking during manufacture. The general limitation for strip width is 10 mm, alternatively 7 mm for strips that are subsequently sintered into a larger format. The maximum possible dimensions can be consulted with our specialists.

Backlighting

BROKISGLASS can be backlit. We’re prepared to help customers create custom solutions, including construction and execution. Backlighting requires a minimum of 100 mm from the surface in relation to the construction, LED panels, and cooling.

Sign-Making

There are limitations to the size and complexity of custom designs. Execution must first be consulted with our team of specialists, who will also recommend the appropriate manufacturing technology (matting/template sandblasting or laser etching). Sign-making falls under custom order and is subject to surcharge.

Design data requirements

Design data must be submitted at 100% scale in vectors; acceptable file formats include .dwg and .dxf. or 3D model. If necessary, we can help customers prepare the data (subject to surcharge).
