As the name suggests, this type of glazing consists of two layers of acrylic, connected in a honeycomb-like pattern to make them more robust. Thus, multi-layer acrylic sheets offer a unique look and much greater stability against outside forces. Canopies made with this material are slightly heavier due to the added material, but they offer great resistance even against gale force winds, hailstorms, and even some forms of vandalism.
Laminated safety glass
Laminated safety glass is made of two sheets of glass with a film of tear-resistant material in-between. These three elements are bounded together on a molecular level by applying intense heat, creating a single thick sheet of glazing with overall increased robustness.
Thus, laminated safety glass offers all the advantages of real glass: It looks great, is robust, and easy to clean. However, despite its increased level of robustness, canopies made with these glazing elements can still be damaged. In fact, while acrylic usually takes only surface damage from hits, laminated safety glass can shatter in its entirety. On the plus side, the shards will still cling to the tear-resistant film instead of scattering around the room. This makes a broken sheet of laminated safety glass much less dangerous than normal glass.
