Insulated Glass Units is widely known and used in construction industry. Rather than stones or cement and wooden windows and doors, the IGU glass appearance and cost saving purpose leads to an advantage that win more people’s choices. It’s a product that uses two or more panels of glass are bonded to a perimeter spacer. Either air or argon gas fills the space between the glass panes. Their primary benefit is insulation and solar control. Can be combined with most types of glass into an insulated glass unit.
♦ COMF-E Optimum
COMF-E® Optimum is a range of highly efficient, premium IGU which uses a wide selection of Low -E glass, spacers and gases to meet our customer’s performance needs.
COMF-E Optimum is a new generation of Landson Glass IGUs that offers optimum performance via a low emissivity coating.
This is specially designed to minimise the amount of heat passing through the glass.
The clever microscopic coating keeps your space cooler in summer by reflecting heat away and warmer in winter reflecting the heat back inside without compromising the amount of light entering your space.
