DE19823081A1 - Double glazing unit installation - Google Patents

Abstract

Double glazing is bonded (6) as individual panes onto the window frame (1,2), filling the pane interval via inlets (3,4) with noble gases or dry air (extreme cold), producing a partial vacuum in the pane interval via valves (8) in the glass or glass carrier material. The glazing is installed by bonding or again by partial vacuum to suit the location and duty. Additional components include an Al diffusion profile (9) etc, not required in the case of diffusive frames and the air is expelled (5) from within the pane interval to generate the vacuum.

Description

Instead of inserting the iso panes into the frame using a complex blocking process, the individual glass panes are placed on the frame and fastened as follows:
By means of a valve integrated in the frame or in the pane, which enables the air in the space between the panes to be extracted, a partial vacuum is created in the space between the panes. Without a vacuum, the adhesive system would have to be designed accordingly - as with car windows.

If desired, another gas can be supplied via a second valve, whereby the air gap remains partially evacuated.

The process can be monitored with any commercially available manometer.

As with double glazing, defrosting is achieved by means of air extraction, in addition, a means for in the frame or in the rungs Moisture absorption can be introduced as with standard insulating glass panes.

The assembly takes place on the frame using adhesive systems such as in automobile construction or by means of rubber or silicone coating.

The extraction, or the gas exchange, can be done on site by any glazing craft operation. Repairs are also easy and on-site feasible.

For safety reasons in the event of leaks are additional Mounting brackets conceivable.

The gas medium could also be customized depending on the requirements (winter - summer) be replaced.

The larger spacing between the panes significantly increases thermal and acoustic insulation, Larger electrically operated shading systems are also protected from the wind possible, additional bars for burglar protection are no problem Can be integrated in the pane spacing, protected against corrosion.

The pane attached to the profiles protects the profile itself against the weather influences and significantly reduces additional protective measures that are otherwise required.

Wooden windows: For wooden windows, an airtight covering (rubber coating or Plastic profile) are pulled over the inner timber. Likewise is one U-metal rail (ALU) conceivable there.

Aluminum or plastic windows: this cover can be dispensed with, applied directly to Frame material.

Rungs: For static reasons (deflection), rungs would be depending on the field size and selected pane strength required. The rungs would get a technical one again and not just a design function. Instead of the rungs could go without saying any punctual spacers or other shapes can be selected (Ornaments or animal shapes such as bird silhouettes).  

Air extraction: via "inverted bicycle valve" and electr. or mechanically operated Suction pumps.

Safety: In the event of a leak, the residual strength of the individual pane can be fixed using an adhesive system or mechanical brackets at the corner points.

Checking air pressure: either by measuring the valve using a display device or optically about possible formation of condensation in the space between the panes.

Thermal and acoustic insulation: higher k-values due to larger air gap (LZR) and dB values achievable.

Accessories: electr. operated blinds, blinds etc. with small actuators between the Windows possible, all wind load problems are eliminated inside the window.

Burglar alarms in the form of metal grids etc. can be retrofitted at any time.

Repair and manufacturing: Any carpenter or glazier "around the corner" could do the simple insulation Manufacture and repair glazing.

Due to the simplicity of the construction are also quite complicated and individual Window shapes again relatively inexpensive.

Weathering: The weathering surface of the support profiles is through the glass panel itself reduced.

No complex sealing work on the window frame or support profile (e.g. Skylights, conservatories) more necessary.

The panes are made entirely by dispensing with separate glazing beads and Cover profiles lighter, the static cross-section of the support profiles can be fully utilized become.

Plexiglass or Makrolon glazing: Due to the relatively high expansion of these materials Iso glazing is not yet possible. Only double-wall sheets with elaborate Expansion joints are currently used as thermal insulation glazing, the proposed one Weg also enables flawless double glazing for this product.
