PL184029B1 - Thermally insulating hollow shape - Google Patents

Abstract

A strip (5,6) provided on one or both sides with a heat-reflecting layer is mounted as a removable insert inside the hollow chamber section (1,2). The strip can be fitted between the reinforcement lining (4) and the inner wall of the section or between the reinforcement lining and outer wall. A groove is preferably provided inside the hollow chamber section for easy insertion/removal of the strip.

Description

The subject of the invention is a heat-insulating chamber profile, especially for windows and doors, equipped with a heat-reflecting layer placed inside the profile.

Insulating profiles of this type are known, for example, from the German patent DE-24 32 746. In this solution, the casing chambers are covered on the outside with a heat-reflecting paint. This significantly improves the thermal conductivity coefficient of plastic windows. Another solution is described in the German patent DE-OS 44 26 331. The flat surfaces of the slats of the chamber profiles are made to reflect heat or are covered with heat-reflecting materials, for example metal (reinforced profile). The German patent DE 34 20 903 presents a solution consisting in spraying the outer and inner walls of the profile with a layer of metal or a metallized foil. In the solution described by the German patent DE-GM 18 66 444, the inside of the profile is filled with plastic foam. A similar solution is presented in the patent DE-OS 29 26 487. According to this invention, the polyester foam also fills the gaps between the inner plastic wall and the metal inserts. Another solution is presented by the invention described by the patent DE-PS 43 31 816. The metal reinforcement with insulating elements is connected by gluing with an insulating element made of foamed material.

The disadvantage of these known solutions is the inability to separate the plastic and metal in the process of recovering the raw material from the profiles made in the described manner or the very high effort required to separate the various types of material.

The aim of the invention is to construct a heat-insulating chamber profile, especially for windows and doors, which will ensure a low thermal conductivity and which will allow easy separation of individual materials in the process of recovering raw materials from door and window frames to be scrapped.

This aim has been achieved according to the invention by constructing a heat-insulating chamber profile equipped with strips embedded in the interior of the profile in specially designed grooves, made of elements covered with a heat-reflecting layer.

A preferred solution according to the invention is the removable fastening inside the profile of strips covered with an insulating layer. Another advantageous solution is to arrange the batten between the profile reinforcement and the internal or external wall of the profile. It is particularly advantageous to provide the chambers of the profile with at least one groove for attaching the insulation strips. Another advantageous solution according to the invention is that the insulating strip is covered on both sides with a heat-reflecting layer.

Due to the implementation of the profile according to the invention, it is possible to achieve a low thermal conductivity coefficient (k <1.3) and to easily recover the raw material from which the profile is made. The described solution applies to both plastic and metal structures.

The invention is explained, for example, in a drawing showing a cross-section of two plastic chamber profiles forming a window structure.

The lower part of the drawing shows the frame profile 1, in the upper part the window sash profile 2, in which the pane 3 is mounted.

The sash profile 2 is provided with a metal reinforcement 4. The metal reinforcement is separated from the inner wall of the profile by means of a lath 5 covered with a reflecting layer embedded in the grooves 2a. The outer chamber of the frame profile 1 on the room side is provided with grooves 2b. Between the grooves 2b and the internal wall of the profile chamber is mounted a strip 6 covered with a heat-reflecting layer. The strips 5 and 6 are made of metal or plastic.

Before installing the chamber profiles of the frame 1 or the sash profiles 2, insert the strips 5 or 6 into the appropriate grooves' 2a or 2b. After disassembling the profiles 1 or 2, the strips 5 and 6 should be taken out, while the plastic elements can be used as a secondary raw material.
