about brokisglass
BROKISGLASS is created using a special fusing technology developed to upcycle discarded glass fragments (cullet) from Janštejn Glassworks, once seen as waste, into a valuable new material. BROKISGLASS panels are manufactured by melting the fragments in a flat mould and then precisely cutting them to the required size and shape using a water jet.
The final appearance of each panel, including its colour and pattern, can be tailored to individual customer requirements through careful selection and arrangement of the glass fragments.
EACH PIECE AN UNREPEATABLE ORIGINAL
BROKISGLASS reflects the sustainable philosophy of Janštejn Glassworks and BROKIS while introducing a new aesthetic and dimension to glass. Its versatility makes it ideal for architecture, construction, interior design, and product design.
Made from recycled glass shards, BROKISGLASS serves a variety of functions, including as a cladding material suitable for both indoor and outdoor applications. When backlit, the panels reveal a unique 3D depth effect, created by the partial melting of the glass fragments.
This makes BROKISGLASS an exceptional choice for designers and architects seeking an original, high-performance cladding material that is both functional and visually striking. Each panel is a one-of-a-kind piece with its own unrepeatable texture and colour composition.

certifications
BROKISGLASS products are certified per the Life Cycle Assessment (LCA) methodology. Following successful completion of the process, an internationally recognized Environmental Product Declaration (EPD) was issued. This comprehensive document provides measurable data on the environmental impact of the products throughout their life cycle.
At the beginning of 2025, BROKISGLASS (together with Janštejn Glassworks) completed the LCA (Life cycle assessment) certification process. LCA is an analytical comparative method for determining potential environmental impacts across the entire life cycle of products. By focusing on the entire life cycle (the so-called cradle to grave), it is possible to detect even environmental impacts that are not apparent at first glance. LCA certification is the most comprehensive and trusted type of environmental statement because it is based on the Life Cycle Assessment method, verified by a third party and certified by a mandated certifying institution. An Environmental Product Declaration is a set of measurable information about the impact of a product on the environment throughout its life cycle (e.g. energy and water consumption, waste production, climate change impact, etc.). This information is determined by the LCA method. Thus, the EPD is a detailed proof of the product on its environmental impact. Below is an overview of EPD for Boards and EDP for Mosaic.

DIFFUSION LAYER
Upon request, a diffusion layer can be applied to the back side of the panels. This special coating improves light dispersion, further enhancing the panels’ illumination properties when backlit. At the same time, it prevents the underlying mounting surface from showing through. The coating is available in white or black and can be combined with a transparent safety layer.
SECURITY LAYER
There are several options for the safety coating: front, back, or both sides. For panels larger than the standard 700 x 700 mm, the safety coating is applied automatically.
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).
SIDES, EDGES FINISH
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. The safety coating is applied to base variant panels above the standard size of 700 x 700 mm. 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.
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°.
The edges on panels larger than the standard 700 mm cannot be mechanically polished. A glossy appearance is achieved by applying a transparent safety coating.
REVERSE 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. The safety coating is applied to base variant panels above the standard size of 700 x 700 mm. 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.
SURFACE TREATMENT
Depends on use. Gloss and matte options are available.
COLOURS
The selection of colour options is based on the standard production of Janštejn Glassworks. Currently, there are 14 colours: 1 Triplex Opal BROKISGLASS, 2 smoke colours in combination with crystal (Smoke Grey Triplex Opal BROKISGLASS and Smoke Brown Triplex Opal BROKISGLASS), and 11 colours in combination with Triplex Opal (white).
In the case of Light Pink Triplex Opal BROKISGLASS, 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.
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 700x700 mm format is approximately 13 kg. Panels in the maximum possible dimensions (surcharge) weigh approximately 17.5 kg.
DIMENSIONS, BASIC DISTRIBUTION
The base variant is flat material with nominal dimensions of 700x700 mm (for a surcharge, the dimnesions can be increased to 1000x1000 mm), that we can subject to a fusing process to bend (curve) the glass according to customer requirements. The maximum angle of curvature is 120°.
