Understand the main factors that influence EN 356 glass cost, including ratings, thickness, panel size and project-specific security requirements.
The cost of EN 356 glass depends on the level of protection required, the size of the glass panels, the laminated build-up and any additional performance features needed for the project.
Because EN 356 glass is a certified security glazing product, it is usually priced according to performance rather than by thickness alone.
EN 356 glass is commonly used for anti-bandit glass, anti-vandal glass and security glazing applications where resistance to impact or manual attack is required.
Lower ratings such as P1A to P5A are generally used for impact resistance, while higher ratings such as P6B to P8B are designed for sustained axe attack resistance.
As experienced security glass manufacturers in the UK, Tecdur designs and manufactures Tecdur Secure Glass —
a high-performance laminated glass range engineered to withstand severe levels of manual attack while delivering cost-effective, project-specific security glazing solutions.

What Affects the Cost of EN 356 Glass?
1. EN 356 Rating
The required EN 356 rating is one of the biggest factors affecting cost.
Lower classifications such as P1A to P5A are tested using steel ball drops and are typically used for impact resistance and vandal protection.
Higher classifications such as P6B to P8B are tested using repeated axe strikes.
These ratings require more advanced laminated constructions and are usually more expensive due to the increased material, testing and manufacturing requirements.
2. Glass Thickness and Laminated Build-Up
EN 356 glass is typically manufactured using multiple layers of glass bonded with specialist interlayers.
As the security rating increases, the glass build-up usually becomes thicker, heavier and more complex.
However, thickness alone does not define performance. The interlayer type, number of glass layers and tested certification all influence the final specification and cost.
3. Panel Size and Quantity
Larger glass panels, bespoke sizes, shaped panes or specialist cut-outs can increase fabrication costs.
The overall quantity also affects pricing, as larger projects may benefit from production efficiencies compared with one-off panels.
Additional Factors That Influence EN 356 Glass Pricing
Additional Performance Requirements
Some projects require EN 356 glass to provide more than manual attack resistance.
Tecdur Secure Glass can be enhanced with additional performance benefits depending on the project requirements.
- Ballistic resistance (EN 1063)
- Blast resistance
- Fire resistance (Exova, CertiFire)
- Acoustic performance
- Switchable privacy glass technology
Combining multiple performance requirements can affect the overall glass specification, thickness, weight and cost.
Framing and Installation Requirements
EN 356 glass must be considered as part of a complete glazing system.
The frame, fixings and installation method need to be suitable for the required security rating.
A high-performance glass panel will only deliver its intended protection if it is installed into an appropriate system.
This is why specification support is important when budgeting for EN 356 security glazing.
Typical EN 356 Glass Cost Guidance
As a general rule, EN 356 glass costs more than standard laminated glass because it is engineered and tested for specific levels of impact or attack resistance.
P1A to P5A ratings are typically more cost-effective than P6B to P8B ratings, which require higher levels of construction and testing.
The final cost will depend on the exact rating, glass size, quantity, system design and any additional performance features.
For this reason, the most accurate way to price EN 356 glass is to request a project-specific quote.
Why Specification Matters More Than Price Alone
Choosing EN 356 glass should not be based on price alone.
Under-specifying can leave a building vulnerable, while over-specifying can add unnecessary weight and cost.
The best approach is to match the EN 356 rating to the real threat level, project requirements and wider glazing system.
Tecdur can advise on the most suitable specification to help balance security, performance and budget.
