Uninsulated section suitable for producing insulated sections for thermal break window and door frames and associated method of assembly

An uninsulated section comprising:

• a first section element and a second section element,
• the first section element comprising a first section wall comprising fixing teeth provided at opposing ends thereof, the first section wall at least partially defining both a first cavity configured to accommodate a portion of a first heat-insulating body and a second cavity configured to accommodate a portion of a second heat-insulating body;
• the second section element comprising a second section wall comprising fixing teeth provided at opposing ends thereof, the second section wall at least partially defining both a third cavity configured to accommodate another portion of the first heat-insulating body and a fourth cavity configured to accommodate another portion of the second heat-insulating body;
• a single connecting partition which forms a sole connection between the first section element and the second section element, the single connecting partition being configured and situated to space apart the first section wall and the second section wall in a manner to provide a cutting line and also to at least partially define each of the first cavity, the second cavity, the third cavity, and the fourth cavity;
• the single connection partition comprising tapered surfaces which mirror corresponding ones of the fixing teeth and together with the corresponding fixing teeth restrict size of a mouth of each of the first cavity, the second cavity, the third cavity, and the fourth cavity.

An uninsulated section comprising:

• a first section element and a second section element,
• the first section element comprising a first section wall, the first section wall having two bends formed at positions spaced away from two opposite ends of the first section wall and further having fixing teeth provided at the two opposite ends of the first section wall, a first cavity being at least partially defined by a first bend of the first section wall and a first fixing tooth of the first section wall and a second cavity being at least partially defined by a second bend of the first section wall and a second fixing tooth of the first section wall, the first cavity being configured to accommodate a portion of a first heat-insulating body and the second cavity being configured to accommodate a portion of a second heat-insulating body;
• the second section element comprising a second section wall, the second section wall having two bends formed at positions spaced away from two opposite ends of the second section wall and further having fixing teeth provided at the two opposite ends of the second section wall, a third cavity being at least partially defined by a first bend of the second section wall and a first fixing tooth of the second section wall and a fourth cavity being at least partially defined by a second bend of the second section wall and a second fixing tooth of the second section wall, the third cavity being configured to accommodate a portion of the first heat-insulating body and” the fourth cavity being configured to accommodate a portion of the second heat-insulating body;
• a single connecting partition which forms a sole connection between the first section element and the second section element, the single connecting partition being configured and situated to space apart the first section wall and the second section wall;
• the single connection partition comprising tapered surfaces which mirror corresponding ones of the fixing teeth.
