VEKAVARIANT EPS Lehr is a high-quality add-on box solution for insulation boxes that is convincing in every respect. Its excellent thermal and sound insulation allows it to meet even demanding specifications for modern residential and commercial properties. The insulation box is suitable for new construction and core renovation. As usual, the insulation box is flexibly and at the same time reliably connected to the window using clips. In addition to all VEKA window systems, the common PVC-U, aluminium and timber profile systems of other well-known manufacturers are also possible here.
