Toughened glass is a safety glass with increased strength both physically and thermally. Glass that has been toughened is 4 to 5 times stronger than annealed.
All toughened glass supplied from Cornwall Glass is kite marked to BSEN12150. We toughen from 4mm to 19mm in thickness and up to 4,500mm x 2,150mm in size in house.
Toughened glass is used in a variety of demanding applications such as stairs or balustrading. At Cornwall Glass, we have a state-of-the-art product=ions plants that ensure all our products are produced with maximum strength. This together with our technical expertise allows us to deliver specialist oversize units for your commercial, trade residential and architectural projects.
Laminated Glass is manufactured by bonding two or more layers of quality float glass together (under a heat and pressure process) with an interlayer of polyvinyl butyral (PVB). Laminated glass is an ideal glass for applications were safety is required.
Laminating glass provides a stronger, more structurally safe glass panel, that if broken, holds the glass fragments together. Perfect for any structural glass requirement. Cornwall Architectural Glass can produce laminated glass panels in sizes up to 6m x 3.2m.
Back painted glass has allowed interior designers freedom of expression when developing concepts for rooms and spaces.
Giving colour to glass, back painting is a stylish and durable solution that can be applied to a variety of your interior glass requirements. Cornwall Glass can provide back painting for glass panels of sizes up to 6m x 3.2m to any given colour, either in BS or RAL numbers. Used predominantly for glass splash-backs for great effect, back painted glass can also be applied in double glazed units. Our back painted glass can also be used for structural bonding.
The great design factor of back painted glass is complimented by its easy cleaning and tremendous durability. When painted on toughened glass, it is also heat resistant to approximately 200 degrees centigrade, ideal for customising your kitchen and bathroom spaces.
We offer straight edge polishing with cerium oxide for a high quality finish. Our state-of the art polishing will give your glass an impressive flat polish.
Our polishing process stands out for its extraordinary production speed while ensuring the best quality finish.
This technique can be used to give a highly polished edged finish to glass. The polishing angle can be altered to your exact specification. Our straight edge polishing machines can cope with massive 6m x 3m glass panel.
Finishes: Bullnose, Bevelled, Mitre, Flat and Arris, Smoothed
Maximum glass size: 6m x 3m
10 polishing and edging wheels
Glass thickness: 4-25mm
Bevelling is a decorative finish usually applied to the perimeter of the glass. Bevelled glass is typically made from 6mm float glass.
The width of the bevel can be varied depending on the desired effect. The Bevell finish acts as prisms creating an interesting colour diffraction which both highlights the glass work and provides a spectrum of colours which would ordinarily be absent in clear float glass.
Cornwall Glass has capability for drilling holes into glass of varying thickness from 4mm – 19mm.
Hole sizes start from 3mm on float glass. We can cut holes to any* size you require. Please contact us to discuss your requirements. *Please the size of the hole that can be drilled is dependent on the thickness of the glass.
Countersunk drill holes: This is where a further angle is cut into the glass, which when a drill piece/screw is used the head of the screw is in-line with the glass, essentially being a flat surface with no raises from the screw heads.
This essentially requires that the glass is heated to a very high temperature, 290°C, and left for a time long enough to fracture a large proportion of the panes which may otherwise fracture in service.
It is a process recommended for glass used in high risk areas where breakage may result in serious injury; sloping overhead canopies (inside pane only), bolt fixed structural glass assemblies and free standing balustrading. The risk is greatly reduced but due to the nature of glass it can never be completely eliminated. To read more about our heat soaked glass please click here.
A specialist process to increase the mechanical and thermal strength of glass making it twice as tough as annealed glass.
The strengthening process increases the mechanical and thermal strength of the glass making it twice as tough as annealed glass.
The glass is heated to a uniform temperature of approximately 650 °C to 700 °C in our Efco furnace. Ceramic rollers move the glass through the furnace at a regulated speed to ensure temperature uniformity and minimal distortion.
Designs are etched into the glass using acid.
By using this process it gives the glass a greater capability for pattern variety. Acid etching can be used for traditional and contemporary designs with varying transparency levels. The diffusion of light through this decorative glass gives truly creative finish.
Our state of the art Waterjet cutter can cut glass into intricate, precise shapes, quickly and economically.
Our Waterjet cutting is perfect for quick cutting of large units, special shapes and bespoke glass projects. Used predominantly for socket cutouts (wall mounted splashbacks), door hinge cut outs and notching the 3 axis cutter allows it to cut any 2D shape out of glass for design or template.
Due to its low heat conductivity and brittleness, glass is not easy to process. The risk of breakage has to be minimized during production due to tensions and micro-cracks caused during the production process.
Cutting glass with conventional methods comes with significant drawbacks due to relatively low scribing quality (micro-cracks, chipping) and accuracy.
Thickness capabilities, from 2mm to a maximum of 100mm.
Maximum pane size 3870mm x 1750mm.
* Please note this process is for annealed glass only
Sandblasted glass is produced by spraying sand at high velocities over the surface of the glass.
This gives the glass a translucent surface, which is usually rougher than that obtained by etching. During sandblasting, areas that are to remain transparent are masked for protection. The depth and degree of the translucency of the sand-blasted finishing vary with the force and type of sand used.
The sandblasting technique is used to obscure visibility through glass, but the glass continues to still transmit light as it is diffused through the surface. Patterns and designs can be created using a mask which resists the abrasive force of the grit from the sandblaster. The mask can be hand cut or computer cut depending on the design.
Traditional Stained Glass
Using traditional methods our skilled and knowledgeable team are able to produce stained glass and leaded glass to order.
We have the capability to manufacture and fit heritage and contemporary stained glass windows, listed properties, new builds and self-build projects. With many years of experience we pride ourselves in the work that we undertake, be it a simple repair to complex and intricate leaded light.
