Performance you can see.
Comfort you can feel.
A high-performance window is more than a frame and a pane of glass. uPVC profiles, glazing and secure locking systems work together to improve insulation, manage heat and create a more comfortable, secure home.
Double Glazing & Better Insulation
Double glazing uses two panes of glass separated by a sealed insulating cavity. Combined with the thermal properties of a uPVC frame, it helps reduce unwanted heat transfer through your windows and doors.
U-Value & Solar Heat Gain
U-value measures heat transfer, while Solar Heat Gain Coefficient (SHGC) describes how much solar heat passes through the glazing. Choosing the right frame and glazing combination can help manage indoor temperatures throughout South Africa's changing seasons.
Multi-Point Security
Unlike a simple single-point latch, multi-point locking secures the opening at several positions along the frame. Together with robust uPVC profiles and suitable glazing, this creates a secure closing system designed for everyday peace of mind.
