New glass door in old frame
Door frames are also known colloquially as door frames. If doors are installed in the shell or are subsequently replaced, the correct dimension of the door frame must be taken into account. What there is to consider:
Is it possible to install new glass doors in old frames?
Door frames, unlike doors, wear out less quickly and very rarely need to be replaced. Therefore, in principle, it is possible to install new glass doors in old door frames. In this case, the dimensions of the new glass door must fit the old door frame. As a rule, most doors, and therefore their door frames, are standardized and are divided into so-called DIN standard dimensions. The most common DIN norms of doors are: 61.0 cm, 73.5 cm, 86.0 cm and 98.5 cm. Depending on the Width of the wall opening, the appropriate dimensions of the door frame opens up.
| Width of your wall opening | Width door leaf (butt door leaf = glass door) |
|---|---|
| 62.5 - 65.5 cm | 58.4 cm |
| 75.0 - 79.0 cm | 70.9 cm |
| 87.5 - 91.5 cm | 83.4 cm |
| 100.0 - 104.0 cm | 95.9 cm |
Determine DIN direction of the glass door: doors are DIN-Left or DIN-Right. If the hinges or hinges are on the left side of the door frame, the door is called DIN-Left. If the hinges are on the right side, it is a DIN-Right door.
The correct glass doors DIN norm measured out
Measure the Height: Measure the folding rule from the top of the floor to the top of the lintel.
Measure Width: Measure the Width of the doorway in at least three places. At the very top of the doorway, in the middle and at the very bottom of the floor. If the measurements are different, the width is determined by the smallest measurement. Before measuring, you can also hold a spirit level, left and right, to the doorway.
As a rule, the dimensions correspond to the usual DIN norms and you can choose your new glass door suitably and without any problems. In the case of special sizes of the door width, special designs must be installed. Glass doors as custom-made products, are cheaper than you might think. The glass door can be inserted into an existing wooden frame. If you are bothered by the material mix of wood and glass, you can also replace it with a steel or aluminum frame at a later date. Whether the existing frame is suitable for the new glass door also depends on the nn existing hinges. Depending on where they are placed on the door frame, they may fit the new glass door or they may need to be repositioned. High quality door frames are important in either case to be able to support the weight of the glass door in the long run. Glass door hinges are divided into two different categories. There are Office and Studio hinges for glass doors. Office hinges are usually a little more stable and are installed in rooms where the door is often used. Studio hinges are usually used in living rooms.



More light and openness in the home
A glass door brings daylight deep into your home - and gives even dark corridors or rooms more space and lightness. Whether completely transparent or with a satin finish, it's impressive how much brightness they can provide without completely sacrificing privacy. It is particularly clever to combine glass doors with slightly tinted or lasered patterned surfaces - this maintains the flow of the room without giving up the desired privacy.
Clever reuse of frames
If a new glass door is to be installed, the old frame can often be reused - provided it is stable and conforms to standards. First measure the rebate dimensions - i.e. the inside edge to the floor and the width along the rebate profile. If the dimensions and door hinge position match, the glass door can be fitted directly. If the dimensions are not correct, the door hinges can be moved or suitable holes for the glass can be drilled precisely - glass cannot be machined on site.


Frame selection: Stability instead of bells and whistles
Glass doors are significantly heavier than wooden doors - around 20 kg/m² compared to around 15 kg/m² for wooden door leaves. You therefore need a frame that can cope with this load. Whether timber, steel or aluminum frames - reinforced hinge pockets and sufficiently strong fittings are crucial. This is the only way to ensure that the door remains reliably in position and does not jam. These additions show how you can optimally integrate your new glass door with light, conscious recycling and a stable choice of frame.
Precisely check technical compatibility
Before planning a new glass door in an existing wooden frame, check the technical compatibility in detail: Are the DIN direction, clear opening dimensions and the rebate/stop situation correct? Classic wooden frames are designed for rebate doors with hinges, whereas glass doors require special glass door hinges (clamping or screw technology) and a suitable striking plate for glass lock cases. Also check the stability and screw retention of the frame (tear-out points, softwood), if necessary retrofit with hardwood dowels/resin. Unfavorable tolerances(crooked reveal fit, uneven rebate gap) can often be compensated forusing adjustable hinges and hinge supports; allow adjustment time for this. Pay attention to the floor clearance (joint height) and any thresholds/carpet edges so that the glass does not rub and the sound insulation does not suffer unnecessarily.
Planning fittings, surfaces & suitability for everyday use
For suitability for everyday use and appearance, it is worth choosing fittings and surfaces with foresight: Choose handles and hinges that match the color of the existing frame (e.g. stainless steel, graphite black, warm brass notes) and consider the area of use - frosted glass has proven itself for privacy in the bathroom/home office; clear glass provides maximum light in the hallway. If the old frame does not have a seal, stops close to the wall, magnetic traps or sealing profiles on the opposite side help to reduce odors and draughts. Soft-close/damper elements or hinge buffers are recommended for quiet closing; for frequent use, a robust lock case with clean closing noises is worth its weight in gold. Finally, document the dimensions, hinge distances and screw patterns - this will allow you to order spare parts, glass drilling patterns and retrofit sets quickly and reliably at a later date.
