Main purposes of window sills

A PVC window sill prevents the penetration of cold into the room from the outside and, conversely, the leakage of heat from the inside. This structural element greatly facilitates the process of servicing metal-plastic windows (when washing glass, opening and closing transoms and windows, hanging curtains, etc.). Finally, the window sill also serves as a functional decoration of the house - here you can install flower pots, souvenirs and other pleasant and necessary little things.
A PVC window sill hides the difference between the thickness of the wall and the window frame and organizes the transition from the interior space of the room to the outside world. It’s no wonder that architects and designers are always so attentive to this seemingly modest detail.
PVC window sill is reliable. It has the same properties as PVC window profiles. The products do not rot, do not decompose, are resistant to sunlight and are absolutely waterproof. Thanks to their multi-chamber design, they are quite strong, rigid, have good heat-insulating properties, are flame-retardant and durable.
