EVERLAM™ SUPER TOUGH, our high modulus PVB interlayer for structural laminated safety glass
EVERLAM™ SUPER TOUGH is a high modulus PVB interlayer for structural applications. This property provides superior strength, stiffness and post-breakage behavior, making EVERLAM™ SUPER TOUGH ideal for applications in glass balustrades, balconies, canopies, curtain walls and sloped and overhead glazing.
EVERLAM™ SUPER TOUGH combines a highly performing product with the superior level of technical expertise and service that has made EVERLAM’s reputation on the market of laminated architectural glass:
- Enhanced structural stability – EVERLAM™ SUPER TOUGH improves mechanical properties of laminated glass so that thinner glass can be used to reduce the weight and cost of the entire glass structure;
- Superior post-glass breakage behavior – a laminated glass structure made with EVERLAM™ SUPER TOUGH is held in place longer than one with a standard PVB, providing a higher level of safety while replacement is organized;
- Modern design – architects can recommend oversized glass panels with minimum visible frames;
- Processability – EVERLAM™ SUPER TOUGH can be processed on a standard lamination line;
- EVERLAM manufacturing standards – it is manufactured according to the EVERLAM standards of high quality and performance consistency;
- EVERLAM commitment – we will proactively test the material with you and provide immediate technical support to help with any issue you may have during the product introduction;
- EVERLAM service excellence – quick response time, on-time product delivery, problem-solving, proactive and collaborative attitude.

EVERLAM™ SUPER TOUGH Specifications
EVERLAM™ SUPER TOUGH performs as well as benchmark products on the market.
| Private Home | Commercial Application | |
| PVB Interlayer | 740 N | 1500 N. |
| EVERLAM™ SUPER TOUGH | 8.8 mm | 16.8 mm |
| Standard PVB film | 22.6 mm | 40 mm |
| Competitive stiff PVB film | 9 mm | 16.8 mm |
| Ionomer film | 8.3 mm | 15.9 mm |
Data source: test performed at KiteGlass, comparing EVERLAM™ SUPER TOUGH with a standard PVB film, a competitive stiff film and an ionomer film (all were 1.52 mm thick interlayers laminated with 10 mm tempered glass), at ambient temperature. The test consisted in applying linear forces of 740 and 1500 N on laminated panels, which caused deflections that were then measured (in mm) and reported. Test method used: BS EN 6180.
