The outer rollers are fitted to the existing joinery (they are applied to the window frame) and have a cassette on the outside. Their cassette is visible, can be oval or 45ᵒ tapered. They are made entirely of aluminum, using the highest quality components so that the resulting product is reliable. The blades are filled with polyurethane foam, which provides high-quality thermal and sound insulation.
Rollite also offers the possibility of incorporating insect netting for your rollers, as insect netting applied to the frame of current joinery is not compatible with roller mounting.
