A method for making a frame for a window comprising the steps of

• providing an insulating abutment list, a sealing strip, and a frame main body, the frame lain body configured as a stationary frame or as a sash frame;
• and
• attaching the insulating abutment list and the sealing strip to the frame main body at a top, bottom, or side members of the main body, the frame main body having an outboard surface configured to face a corresponding outboard surface of a frame secondary body of a window, wherein the insulating abutment list is on the outboard surface of the frame main body and configured to face the corresponding outboard surface of the frame secondary body of the window, the abutment list made from a different material than the main body and the sealing strip, the different material having a thermal conductivity of less than 0.08 W/(m·K), the frame main body further having hinge parts attached to the two side members to define therebetween a hinge axis, the hinge axis residing substantially parallel to the top member and the bottom member, and wherein the insulating abutment list substantially covers the side surfaces extending from the hinge axis to either the bottom or top member.
