How do you choose the right glass for a home project?
Choosing the right glass for a home project comes down to three core factors: where the glass will be installed, what safety requirements apply to that location, and what visual or functional finish you need. Safety glass, either toughened or laminated, is legally required in many domestic settings, including shower enclosures, balustrades, and low-level glazing. The questions below walk through each key decision in turn, from glass types and legal requirements to thickness, finish, and ordering made-to-measure panels.
What types of glass are used in home projects?
The most common glass types used in home projects are toughened glass, laminated glass, painted or decorative glass, and low-iron glass. Each type suits different applications depending on the safety requirements, aesthetic goals, and environmental conditions of the installation.
Toughened glass (also called tempered glass) is heat-treated to increase its physical and thermal strength. In the rare event of breakage, it crumbles into small, blunt fragments rather than sharp shards, making it the standard choice for shower screens, balustrades, glazed doors, and other high-risk locations.
Laminated glass bonds two or more glass panes together with an interlayer. When broken, the fragments tend to stay adhered to the interlayer rather than scattering, which makes it particularly suitable for overhead glazing, balustrades, and anywhere that glass retention after breakage is important.
Beyond these safety constructions, homeowners can also choose from a range of finishes and visual options:
- Low-iron glass: reduces the green tint visible in standard clear glass, offering improved colour clarity for splashbacks, shower enclosures, and premium interior glazing
- Satin and frosted glass: diffuses light to provide privacy without blocking it entirely, suited to bathroom screens, internal doors, and partitions
- Tinted glass: available in bronze and grey options, used for decorative or architectural effect in interior applications
- Painted and digitally printed glass: offers solid colour finishes or bespoke patterns, commonly used for kitchen splashbacks and decorative wall panels
- Mirror glass: used for decorative panels, bathroom mirrors, and feature walls
The visual finish chosen does not determine the safety construction. A painted splashback, for example, still needs to be made from toughened glass if it is positioned near a heat source or in a location covered by building regulations.
Where in a home does safety glass become a legal requirement?
In the UK, safety glass is a legal requirement in any critical location as defined by British Standard BS 6206 and referenced in Building Regulations Approved Document K. These locations include glazing in doors and side panels, low-level glazing below 800 mm from floor level, shower enclosures, balustrades, and staircase glazing.
The underlying principle is that glass in areas where people are likely to come into contact with it, whether through impact, a fall, or routine use, must break safely. Standard annealed glass shatters into large, dangerous shards and does not meet this requirement.
The most common critical locations in a domestic setting include:
- Shower enclosures and wet rooms: all glass must be a recognised safety glass type
- Balustrades and Juliet balconies: glass acts as a barrier against falls and must meet structural as well as safety glazing standards
- Glazed doors and door side panels: any pane within 1,500 mm of the floor in a door or within 300 mm of a door opening edge
- Low-level glazing: any pane with its lowest edge less than 800 mm above floor level in a domestic setting
- Staircase and landing glazing: glass alongside or beneath stairs where a fall hazard exists
If you are unsure whether a specific location in your home requires safety glass, the safest approach is to assume it does and specify toughened or laminated glass accordingly. Non-compliance can create liability issues and may be flagged during property surveys or insurance claims.
What’s the difference between toughened and laminated glass?
The key difference between toughened and laminated glass is how they behave when broken. Toughened glass shatters into small, relatively harmless fragments. Laminated glass holds together after breakage because the fragments adhere to an interlayer, typically a polyvinyl butyral (PVB) film, bonded between two glass panes.
Both are classified as safety glass and both meet the requirements for critical locations under UK building regulations, but they suit different applications based on their specific properties.
When toughened glass is the right choice
Toughened glass is typically the more cost-effective option and is widely used for shower screens, splashbacks, balustrade infill panels, glazed doors, and internal partitions. It is processed by heating the glass to around 680°C and then rapidly cooling it, which creates internal stresses that give it significantly greater strength than standard glass. Because it cannot be cut or drilled after toughening, all dimensions, holes, and cut-outs must be specified before manufacture.
When laminated glass is the right choice
Laminated glass is preferred in situations where glass retention after breakage is critical. Overhead glazing, roof lights, and balustrades where falling glass could injure people below are common examples. It is also used where acoustic performance or additional security is needed, as the interlayer adds sound dampening and resistance to forced entry. Laminated glass can be produced in a variety of thicknesses and constructions depending on the structural and safety requirements of the installation.
In some applications, particularly structural balustrades and frameless systems, laminated toughened glass combines both properties: the strength of toughened glass with the retention characteristics of lamination.
How thick should glass be for balustrades and shower screens?
For shower screens and shower doors, 8 mm or 10 mm toughened glass is the standard recommendation depending on the panel size, design, and supporting hardware. For balustrades, the required thickness is higher, typically 10 mm toughened or laminated toughened glass as a minimum, with thicker specifications required for frameless systems or larger panels.
These two applications have very different structural demands, so their thickness requirements should not be confused.
Glass thickness for shower screens
An 8 mm panel is suitable for most standard shower screen configurations when properly supported with appropriate fittings. A 10 mm panel provides additional rigidity and is commonly specified for larger panels or pivot door arrangements. The number of hinges also matters: two hinges are generally appropriate for standard shower doors, while doors taller than 2 metres typically require three. Always confirm thickness against the hardware manufacturer’s load limits for the specific installation.
Glass thickness for balustrades
Balustrade glass must resist lateral loading, the force applied when someone leans or falls against the barrier. The required thickness depends on the balustrade system type (frameless, post-supported, channel-fixed, or fully framed), the panel height, and the fixing method. Frameless glass balustrades that rely entirely on the glass for structural support require thicker glass than post-supported systems where the posts carry the load. For glass balustrades, specifications must be assessed for each installation rather than assumed from a single figure.
Should you choose toughened glass or standard glass for a splashback?
You should choose toughened glass for a kitchen splashback. Standard annealed glass is not suitable for splashback installations because it cannot withstand the thermal and mechanical stresses of a kitchen environment. Toughened glass offers significantly greater resistance to heat and impact, and if it does break, it does so in a far safer way than ordinary glass.
The heat generated by hobs and cookers is the primary reason toughened glass is the appropriate choice. However, the suitability of any splashback near a specific appliance must still be confirmed against the manufacturer’s installation requirements and the recommended clearances from the heat source; no glass type is unconditionally heat-proof at all distances.
Beyond the safety case, toughened glass splashbacks also offer practical advantages for the home:
- A smooth, non-porous surface that is easy to wipe clean
- Available in a wide range of finishes including solid painted colours, digitally printed designs, mirror, glitter, and clear options
- Made to measure for an exact fit, including cut-outs for electrical sockets
- Low-iron glass can be specified where colour accuracy is important, as it reduces the green tint visible in standard clear glass
One important practical point: electrical socket cut-outs must be specified and measured accurately before the glass is manufactured. Because toughened glass cannot be drilled or modified after processing, any cut-outs must be included in the original order. Measurements should be taken from the socket backplate rather than the faceplate to ensure the correct clearance.
How do you get glass cut to size for a bespoke home project?
To get glass cut to size for a home project, you need to provide accurate measurements, and in some cases a physical template, to a specialist glass supplier who offers made-to-measure processing. The glass is then cut, edge-finished, and toughened to your specified dimensions before delivery. All custom details such as holes, cut-outs, and polished edges must be confirmed before manufacture.
The process typically follows these steps:
- Measure accurately after surfaces are complete: for shower glass, measure after tiles, trays, and flooring are installed; for splashbacks, measure after worktops and cupboards are fitted. Measuring too early leads to panels that do not fit correctly.
- Account for irregular walls and floors: walls are rarely perfectly vertical and floors are rarely perfectly level. Measure at multiple points and allow for the clearances required by channels, hinges, and seals.
- Use a template for complex shapes: for non-rectangular panels or walls with unusual profiles, cutting a physical template from hardboard or MDF helps reproduce the exact shape and identify the position of any cut-outs.
- Specify all custom details upfront: holes for handles, hinges, or fixings, socket cut-outs, notches, and polished or bevelled edges must all be included in the order before toughening takes place. They cannot be added afterwards.
- Choose the right glass type and thickness: confirm which glass construction is required for the location (toughened, laminated, or laminated toughened), and select the appropriate thickness for the panel size and installation method.
CNC machining allows precision cutting to virtually any shape or size, including circular panels, angled cuts, and complex profiles. Made-to-measure glass is available in a wide range of thicknesses and finishes, so the order should specify not just dimensions but also edge finish, any surface treatment, and the glass type required for the application.
