The present invention relates to a window frame with a good insulation effect, wherein an insulation fame made of PVC material having good insulation capability is engaged to a pair of exterior frames made of stainless steel or steel material disposed on the indoor or outdoor side, and to connect the indoor and outdoor exterior frames thereby preventing direct contact between the exterior frame positioned on the indoor side and the exterior frame positioned on the outdoor side; thus preventing heat conduction between the indoor and the outdoor through the exterior frames. The window frame having a given length and width to support an end of glass on one side or both sides of the center in a width direction includes: an insulation frame having first and second insulation members of a rectangular frame, a glass fastening portion formed between the first and second insulation members to receive the glass therein, and a coupling member to connect the first and second insulation members; and an exterior frame having a first exterior member to cover the outer side of the first insulation member and a second exterior member to cover the outer side of the second insulation member. The first insulation member is formed in a closed rectangular frame, and the inside is divided by a partition to form two insulation spaces. The coupling member is formed with a coupling insulation space therein. |
