When choosing windows for their four bare walls, the investor has a tough nut to crack. Manufacturers are outdoing one another in the design of joinery, improving the specifications of both the glazing and the profiles. It is easy to get lost in the multitude of parameters and models. A thermal frame is a universal solution that improves the quality of every window. Why? Because even if we select a frame of excellent quality and the proper glazing, heat will escape at the point of contact between them. To avoid this, MTS uses thermal frames to assure our customers’ comfort.
