Performance Glass (Low E)

Also commonly known as Low E (Low Emissivity) or smart glass, this range of glass has a coating which provides various solar and thermal protection. Performance glass was first developed to reduce the amount of ultraviolet and infrared light that can pass through glass without lowering the amount of visible light coming through.

By reducing the amount of transferred heat, Low E glass allows a building to become more energy efficient by keeping the cool air inside in tropical climates. Other types of performance glass have the reverse benefits in colder climates.

Performance ratings are set to a SHGC (Solar Heat Gained Co-efficient) rating, a U-value rating, a VLT (Visible Light Transmittance) and a VLR (Visible Light Reflectance) rating.

Solar Heat (SHGC) is the solar radiation transmitted.
Infared Light (U-Value) is the thermal Insulation rating.
It’s important to evaluate the differences in these ratings when choosing the right glass for your application.

Splashbacks

Splashbacks are extremely popular as an alternative to tiles when building or renovating. Produced with toughened glass, splashbacks are able to be painted to your own colour choice enabling you to match colour themes within the home.

Pool Fencing

Safety fencing around pools is extremely important and now mandatory by law. With glass it’s easy to achieve a beautiful yet virtually invisible screen to protect your family and pets.

Mirrors

Mirrors have multiple uses within the home and they provide us with reflection but are also a great way to open up a space and multiply the light. Glasstech can custom make to your specific measurements and edge finish requirements.

Balustrade

Safety glass is the smart and reliable option for all balustrade applications. Heat strengthened laminate or the option of frameless toughened glass should be considered for your home, apartment or commercial application.
