This is a double glazed uPVC dual top hung window with laminated glass and has a uValue of 1.1. PPP - V top hung and pivot windows are made of aluminium steel and plastic. The window design enables the sash to be opened in outward or pivot function. The outward opening function enables the sash to be opened in any position from 0 to 35 degrees. It enables an easy approach to the opened window and ensures a wide view to the outside. The pivot function enables the sash to be rotated through 180 degrees. The patented innovative operating mechanism guarantees complete sash stability in outward and centre pivot function as well. The opening method can be selected by using the preSelect sliding switch positioned in the middle of the frame. The installed V35 air inlet ensures fresh air inflow while the window is tightly closed. The top hung and centre pivot window is intended to be installed in particular in loft rooms with elevated humidity levels (kitchens, bathrooms). The PPP - V window is made of multi-chamber PVC white profiles, strengthened from the inside with galvanized steel profiles. The roof window is durable, corrosion free, resistant to changeable weather conditions and its maintenance is reduced to an absolute minimum. The plastic used in the window production does not absorb any moisture and is resistant to acid or alcohol action. Operated by the handle positioned on the lower part of the window, opening method can be selected by using the preSelect sliding switch. Properties Window uValue: 1.1 W/m2K.
