The Alspec Carinya Sliding Window is an excellent and well designed residential window. With ratings up to BAL40, it can withstand wind and water pressures well above those found in cyclone prone areas. The 47mm frame uses a two sash system that provides a sleek minimalistic look. It can accommodate single glazing from 4-10/10.38mm as well as double glazing from 16-18mm. With lockable latches and adjustable height rollers coming as standard, The Carinya sliding window comes with mullion latches meaning returning tiles into the frame wont affect the operation.
