AI Technical Summary

Technical Problem

Existing caulking methods for joinery frames, such as windows and doors, are time-consuming and complex, requiring manual application of sealants or impregnated foams, and often necessitate precise gluing to ensure effective sealing, which can be challenging and inefficient.

Method used

A pre-frame subframe is used, comprising co-extruded profiles with distinct plastic or composite materials for fixing and sealing, allowing for easy installation and compensation for irregularities without adhesives, using cohesive bonding for enhanced durability.

Benefits of technology

The pre-frame subframe simplifies caulking by providing a pre-assembled solution that compensates for frame irregularities, ensuring effective sealing and reducing installation time and complexity while avoiding adhesive drawbacks.

Abstract

A sealing subframe (30) between a window or door frame (10) and a frame (12), the subframe (30) defining a closed contour and comprising elongated profiles (32), at least some of which are joined to each other by their longitudinal ends (32a), characterized in that each profile (32) is produced by co-extrusion and comprises two longitudinal parts (34, 36) joined to each other by co-extrusion, a first part, called the fixing part (34), being made of a first plastic or composite material having a first hardness and being suitable for fixing the profile (32) to the frame (18), and a second part, called the sealing part (36), being made of a second plastic or composite material having a second hardness lower than the first hardness and being suitable for sealing between the frame (18) and the structure (12).
