What is Laminated Glass?

Laminated glass is a type of safety glass that holds together when shattered. Unlike regular glass, it doesn’t break into sharp, dangerous pieces. Instead, the glass remains bonded by an interlayer, usually made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA).

How is it Made?

Laminated glass is created by sandwiching the interlayer between two or more layers of glass. The layers are then heated and pressed together, forming a strong bond. This process ensures that if the glass is broken, the shards stay attached to the interlayer, reducing the risk of injury.

Benefits of Laminated Glass in Composite Doors

Security

Laminated glass is much harder to break than regular glass. The 6.8mm laminated layer within the 28mm double glazing provides a robust barrier against forced entry attempts.

Even when struck with considerable force, the glass will crack but remain intact, preventing easy access. The tough interlayer significantly delays intruders, making it extremely difficult for them to gain access.

This can be crucial in deterring burglars, as the added time and effort required to break through laminated glass can discourage attempts altogether.

Safety

Laminated glass offers exceptional safety benefits. In the event of breakage, it does not shatter into dangerous shards. Instead, the interlayer will hold nearly all of the fragments together, maintaining a barrier even when damaged.

This ensures that your home remains secure, even if the glass is compromised. Another benefit is the added safety for young children. The bonding strength of the interlayer makes it difficult for intruders to create an opening large enough to gain entry, even after multiple attempts.

Impact Resistance

The impact resistance of the 6.8mm glass in composite doors is designed to withstand high impact. This makes it not only ideal for security but also for protecting against accidental damage or severe weather conditions.

Laminated Glass in Sidelights

Having laminated glass in sidelights is especially beneficial if your door has a thumbturn lock. In such cases, an intruder might try to break the sidelight glass to reach the thumbturn and unlock the door from the inside.

When the glass is laminated, this become very difficult. Even if the glass is broken, the interlayer holds the shards together, preventing easy access to the thumbturn. This added layer of security ensures that your door remains secure, even if someone attempts to exploit the thumbturn lock through the sidelight.
