PVC roof windows

The centre-pivot window turns about its central axis, so it opens by rotating on its own axis. The double-opening window, like the windows of the preSelect MAX series in the Fakro catalogue, opens both as a centre-pivot and as a projecting window, that is, with the sash projecting outwards. Choose the type of opening according to how the room is used and whether you can reach the window.

Start from the measurement of the existing opening in the roof slope, that is, the width and height of the hole, and consider the pitch of the slope, which affects the dimensions of the window. Measure at several points to check that the opening is square. When the measurements do not match a standard window, the product sheet gives the available dimensions.

A PVC frame does not need painting and resists moisture well, so it is suited to bathrooms and kitchens, where steam is frequent. Compared with wood it needs less maintenance. Check the product's marking and the insulation characteristics in the product sheet before buying.

The centre-pivot window turns about its centre and lets air in when it is open. The double opening is useful when you need both ventilation and access to clean the glass from inside, because it also opens in the projecting position. The choice depends on the installation height and on how the room below is used.

The term vasistas indicates a projecting opening, with the sash opening from the top edge, while the term bilico indicates rotation about the central axis (centre-pivot). The name given in the title, Vasistas Bilico, shows that the model combines the two. To understand exactly how it opens, check the drawing and the mechanism in the product sheet.

Installation involves working on the roof slope, with the risk of falling from height. Use fall-protection systems, such as anchored harnesses, and do not walk on the tiles. Follow the manufacturer's instructions, because the frame must be fixed and sealed to the roofing. For work at height, the rules of Italian Legislative Decree 81/2008 on workplace safety apply.

Yes, the PVC frame is suited to bathrooms and kitchens because it is not affected by moisture and does not need painting. For the bathroom, it is also worth checking the ventilation of the room. Check the product sheet for the intended use in the environment and for compatibility with the seal and with any glass chosen.

The PVC frame is cleaned with lukewarm water and a neutral detergent, using a soft cloth. Avoid solvents, abrasives and rough sponges, which can dull the surface. Clean the seals too, removing accumulated dirt that can make them lose elasticity.
