Stiff/Rigid Interlayer Glass

Pro Lam Tuf + represents Glass Projects’ premium offering in high-performance safety and structural glazing. This advanced laminated glass is constructed using two or more lites of toughened safety glass, bonded together with a specialised stiff or rigid structural interlayer, such as an ionoplast (e.g., SentryGlas) or an equivalent high-modulus interlayer. These interlayers are significantly stiffer and stronger than standard PVB, allowing the laminated glass to behave more like a monolithic unit, offering enhanced structural performance both before and after potential breakage.

Key attributes of Pro Lam Tuf + include:

• Superior Post-Breakage Strength: Even if all glass lites are broken, the stiff interlayer can maintain significant structural integrity and load-bearing capacity, far exceeding that of PVB laminated glass.

• Enhanced Structural Efficiency: The increased stiffness allows for potentially thinner glass constructions or larger panel sizes for a given load compared to PVB laminates, leading to lighter overall assemblies and greater design freedom.

• Improved Edge Stability & Durability: Stiff interlayers typically offer greater resistance to moisture ingress and delamination at exposed edges, making them ideal for demanding environments and frameless applications.

• Exceptional Clarity and Low Yellowing: Many structural interlayers provide outstanding optical clarity and are less prone to yellowing over time compared to some PVB interlayers.

• Increased Impact Resistance & Security: Offers a very high level of resistance to impact and forced entry due to the combined strength of toughened glass and the robust interlayer.

Glass Projects specifies Pro Lam Tuf + for the most demanding architectural applications where maximum strength, post-breakage integrity, and design minimalism are critical. It is the ultimate choice for:

• Frameless Structural Balustrades: Ideal for cantilevered or minimally supported glass balustrades, especially those with exposed edges, ensuring superior safety and rigidity.

• Glass Fins and Mullions: Allows glass to be used as a primary structural element in facades, supporting significant wind loads.

• Walkable Glass Floors and Stair Treads: Provides exceptional strength and critical post-breakage support for overhead pedestrian traffic.

• Large Span Overhead Glazing: Suitable for expansive glazed roofs, canopies, and skylights where high loads and critical safety are paramount, particularly where post-breakage performance is a key design driver.

• Blast & Cyclone Resistant Glazing: Can be engineered as a component in systems designed to withstand extreme events (note: specific system design and certification required, refer to Pro Shield Range for dedicated cyclone solutions).

• Point-Fixed Glazing Systems: The rigidity of the interlayer helps to distribute stresses more effectively around fixings.

Glass Projects’ design team leverages the unique properties of Pro Lam Tuf + to engineer innovative and safe solutions for complex and structurally demanding glazing challenges across New Zealand, ensuring meticulous attention to detail in specification and installation.
