Double Glazed units






The Types of Glazed Units Supplied by Crucial
Single Glazed units
Single Glazed units have many different uses when it comes to styling your premises. For example you can use our single glazed units to add partitions, shelving, infill panels, glass balustrades, Juliet balconies and glass doors. Creating a stylish and modern look to any environment.
For most of these uses we recommend using frameless polished edge toughened glass between 10-12mm, giving a minimalist design that is still practical whilst looking sophisticated.
Double Glazed Units
Our Double-Glazed units are manufactured in house in a variety of custom sizes. By reducing the amount of heat that may escape from a building through your windows they are contributing to making a property more energy efficient. They are the perfect choice from any building of an age that tends to have lower energy efficiency than modern builds.
