Kit for, an insulating glazing

Invention relates to a kit for retrofitting Attachment of insulating glazing to existing one or multiple glazed windows, doors or the like. with a single pane of glass and arranged around its edges and thus - with the interposition of a seal - inseparably connected, hollow spacer strips that accommodate a molecular sieve, which is also permanently attached to the existing glazing with the interposition of a seal and with a lamination frame for end covering.

Isoller glazing, which consists of two im There are spacing from one another by means of spacer strips that are firmly and air- or water-vapor-tight connected glass panes. If there is single glazing in doors or windows to be replaced by such insulating glazing, a considerable amount of work is required. The before » Existing putty joints must be expanded after the existing glazing has been removed. According to special regulations the double glazing must then be reinserted into the expanded cement joints.

In order to reduce the workload and costs involved save or significantly reduce, double glazing has become known, in which in addition to the existing glazing hinged glazing on the door or window

frame is attached. This is therefore made to be as a result Contamination or moisture from leaks from the space between the two panes of glass to be able to remove. Although the existing glazing can be retained, the attachment of the additional glass pane must just like the installation of the finished double glazing, can be carried out by specialists. Would Laypeople attempting to create this double glazing using the do-it-your-eleven method would result in subsequent disruptions of double glazing will be inevitable.

f In order to create the possibility of attaching an additional pane, preferably for single-pane glazing that has already been installed, for example using the do-it-yourself method, it has become known that the additional pane forms a unit with a spacer to which it is firmly connected by an adhesive, whereby the surface of the spacer facing the single-pane glazing is provided with an adhesive compound that forms a gas-tight connection between it and the front pane when it is inserted into the single-pane glazing (DE-GM 77 19 752.) .. In the hollow spacers there is a so-called hygroscopic material Molecular sieve arranged,

C. It has been found that only experts can use this to create double glazing using the do-it-your-yourself method can be. In this case, disturbances are, for example, when applying the adhesive when inserting sealant or when the molecular sieves are introduced, when the corners of the spacers are brought together, interference is inevitable.

Multi-pane glazing was also originally known single glazed windows to double glazed windows that with an edge structure consisting of: -: spacer frame,

Sealant, a molecular sieve and an adhesive on a single pane of glass is marked, which after joining with a single pane that has already been glazed, a multi-pane insulating glazing (DE-GM 77 07 013.4).

This, too, does not give the layman enough security to create double glazing using the do-it-yourself process. The consequence of this are leaks that eventually lead to removal the double glazing lead.

Finally, a kit for insulating glazing has become known of windows, doors or the like. Which already have single glazing. This kit is marked through a single pane of glass with spacer strips arranged around its edges and thus permanently connected to the Put on the existing one. Single glazing of the window of the door or the like. or through a single pane of glass, the spacer strips for gluing on the existing single glazing of the circumferentially arranged at their edges Window, door or the like, whereas covering, fastened around its edges, closes the single pane of glass - and on the frame of the window, the door or the like. attachable cover strips, which in the assembled state have a surrounding frame form and press against the single pane of glass (DE-GM 78 23 498).

Although this is a kit for insulating glazing, especially for laypeople is offered, it has been found that it is desirable to improve this kit significantly, Above all, to enable greater security and practicality in the attachment and assembly of the individual parts.

The present invention is therefore based on the task of providing a kit for retrofitting an insulation

To create glazing of the type mentioned above, through which a layman is repaired, with great certainty one himself Double glazing to be attached to existing single or multiple glazed windows and doors.

It has been found that this problem can be solved in a simple manner in that the hollow spacer bars through in . their end openings insertable spacers are connected to one another, and facing the panes of glass Have surfaces channels for receiving sealing material.

r This makes it possible to limit at their ends by line perpendicular to the edge regions extending cuts. ■ Fermentation at the end of the spacer bars is completely avoided. The spacer bars can be offered in different lengths. They can then be shortened to the necessary length after purchase. The spacers are matched to the dimensions of the spacer bars. At the same time, they completely fill the space between the spacer bars. Because channels for receiving sealing material are provided on the surfaces of the spacer strips and spacers facing the glass panes, this sealing material is easy to apply without the hitherto unavoidable smearing, which is later visible through the glass panes, occurs;

pieces and the spacers, the spacers can be filled with molecular sieve. This molecular sieve or the moisture-azobbing material is added to the kit in the form of airtight sealed tubes. The tubes can be provided with cartridges by avoiding the molecular sieve is filled into the hollow spacer strips from moisture absorption. The intermediate pieces can have different shapes. In a first embodiment, the intermediate pieces are at right angles mutually extending spigot ends. These spacers are usually used to join the spacer bars at the corners-used.

In a second exemplary embodiment, the intermediate pieces have plug-in ends that run in a straight line with respect to one another. These Intermediate pieces are used, for example, in large windows and doors to join spacer bars Length is less than the length of the door or window glazing.

In a further embodiment, the intermediate pieces spigot ends running at any angle between 180 °. These spacers are usually used to join together used by spacer bars, which are usually shorter than the spacer bars mentioned above. These Intermediate pieces can be used to attach double glazing to arched areas of doors and window frames to fit in. Here, too, the spacers are in front of the Put together with the intermediate pieces with molecular sieve: filled.

A particular advantage is that they close to the panes of glass Areas of the middle pieces of the intermediate pieces according to the spacing strips, channels for receiving cover material exhibit.

In this way, it is possible to avoid the distant and To provide spacer frames plugged together with spacers around the circumference without the risk of smearing · with sealing material.

It is also particularly advantageous that the sealing material in the initial state as a strand or cord with a cross section is formed, which corresponds to the cross section of the channel or the channels in the spacer strips or the intermediate pieces. In this form, the strand-like or cord-like sealing material can easily be added to the kit. It can be provided with oil paper to protect it from sticking or soiling of the hands is avoided.

A special embodiment of the kit according to the invention is characterized in that each facing a pane of glass Surface of the spacer strips and the intermediate pieces each provided a channel with a semicircular cross-section and that the sealing material is used as a sealing cord formed with a round cross-section in the initial state which corresponds to the shape of the channels. Since the sealing material is soft, any layperson can simply use the circular Insert the cord into the corresponding channels and then cut it to length. When joining with the respective Glass plate, the sealing material can then cover the entire width of the spacer strip or the intermediate piece spread.

In all embodiments of the invention, sealing pieces are provided that the outer surface of the intermediate pieces and cover the adjacent edge areas of the adjoining spacer strips. This is a safe, even by layman executable Sealing of the critical areas between two spacing strips that meet each other.

The sealing pieces and the sealing material, especially the sealing strands or cords are used as a water vapor barrier educated. It is advantageous if used as a water vapor barrier known butyl is used.

IM another security against ingress of moisture The areas between the window or door frames and the spacer strips and the two panes of glass must be ensured filled with sealing strips. These can, wound up, can also be added to the kit in the required quantity. By pulling more or less hard when inserting the sealing strands into the intended Intermediate spaces, the amount of material can be adapted to the respective spaces to be sealed.

The sealing pieces on the outer surfaces of the intermediate pieces and the edge areas of the spacers can be up to Fensterbzw. Reach the door frame. Without anything at the core of the invention To change, however, sealing material can also be used between the sealing pieces and the window or door frame are provided. . .

In order to ensure an easy and safe attachment of the new glass pane to the existing glazing, spacer blocks are provided between the spacer strips and the opposite areas of the window or door frames. The spacers are placed on the window frame before the sealing strips are inserted. Then will The glass pane with the spacer strips is placed on the spacer blocks and folded in. This is how it is possible that the added glass pane can be attached to the existing glass pane without the windows or Doors need to be removed.
