Manufacturing and Cutting Impact-Resistant Glass

Impact-resistant glass, or laminated glass, can be manufactured in three different ways.

The first way is by bonding two or more pieces of glass together with layers of plasticized polyvinyl butyric (PVB) resin between them. Heat and pressure ensure a tight, safe seal.

Alternatively, two or more pieces of glass and polycarbonate can be bonded together by heat and pressure with a different interlayer, one of aliphatic urethane instead.

The third method of manufacturing impact-resistant glass is to interlayer glass sheets with a cured resin.  This makes a high quality type of Impact-Resistant Windows.

As expected, these multi-layered glass products can be difficult to cut and it should only be done by trained technicians using either specially made laminated cutting tables, vertically-angled saw frames or a hot air blower or blowlamp.

Warning: Never attempt to cut both sides of impact-resistant glass by pouring flammable liquid into a crack and the lighting it in order to melt the layers into separate pieces.  Impact-Resistant Windows are the backbone of hurricane home protection, along with Impact-Resistant Doors which will be discussed in a separate blog post.
