Guardian® Heat Barrier

Guardian® Heat Barrier low-e glass products have been used by leading manufacturers for over 30 years to help keep consumers safe. Heat Barrier products are specially designed to manage heat within home appliances.

Oven glass that loves the heat

The Guardian Heat Barrier range of Low-E glass is specially designed to handle the considerable heat generated by ovens, particularly during the self-cleaning process. To protect consumers from this, and deliver ovens that help enhance modern kitchen design, leading manufacturers often turn to Guardian Heat Barrier™.

This is our lowest emissivity appliance coating yet, and has a subtle reflected blue color that’s especially effective with stainless steel.
