IT'S THE DEPTH THAT COUNTS
How to determine the ideal insertion depth
The insertion depth defines, so to speak, the available space within the frame and is an important criterion when configuring the picture frame. Our magnetic frames in the versions Classic, Distance and Conservo are supplied with a standard insertion depth of up to 2 mm for pictures/passepartouts. In most cases this is sufficient for a picture with passepartout, but please pay sufficient attention to the subject so that an optimal presentation of your pictures is guaranteed. Below we provide some useful information on how to determine the ideal insertion depth.
The decision on the insertion depth is less a design decision than a purely technical one. The frame must be adapted to the image on its substrate and, if necessary, to the thickness of the passepartout. The insertion depth is calculated as follows:
Image thickness + passepartout thickness = insertion depth
1.5 mm + 3.0 mm = 4.5 mm
0-2mm. Suitable for thin to very thick paper or common paper (e.g. 300g/m²) with 1.5mm passepartout.
Image thickness: 0,5mm + passepartout thickness: 1,5mm = insertion depth: 0-2mm
With insertion depth:
If the inserted material exceeds 2mm thickness, the frame must be adjusted to the total thickness. For example for Dibonds, framing with 3mm passepartout or in folding passepartout, as well as working on a carrier cardboard. An individual insertion depth allows a tolerance of up to 25 mm.
Image thickness: 1.5mm + passepartout thickness: 3mm = insertion depth: 4.5mm
On request we produce the frame or the basic element of the frame with an increased insertion depth according to your specifications, without extra charge. This may be necessary, for example, if you want to insert a 3 mm thick folding passepartout, a concealed picture on a Dibond plate or the D5 inlay frame into the frame.
However, there are two exceptions:
The standard insertion depth of the protect magnetic frame is 8 to 9 mm - depending on the type of glass selected (Mirogard Protect = 8 mm ET, all other types of glass = 9 mm ET).
The insertion depth of the magnetic display frame is 0.25 mm and cannot be varied. With this frame variant, the poster is inserted into the Posterfix module and holds the poster by the clamping effect without self-adhesive fixation or similar. The paper of the poster can be up to 0.25 mm thick - depending on the type of paper, this corresponds to a paper with a grammage of max. 300 g/qm.
The basic element of a HALBE magnetic frame is the rear wall of the frame. It consists of several components: the outer element is always a steel sheet angle frame on which the aluminium or solid wood frame is magnetically placed. The material of the actual rear wall and the construction of the basic element in detail depend on the frame type - accordingly, there are a few tips worth knowing about the insertion depth for each frame type.
Below we briefly explain the differences for the individual frame variants in the HALBE product range:
The basic element of the Classic magnetic frame is a dimensionally stable composite of a PAT-tested rigid foam plate and a sheet steel angle frame.
The sheet metal angle extends a few millimetres beyond the surface of the rigid foam panel. This ensures that picture and glass are held securely in the frame. As standard, up to 2 mm material thickness fit under the glass pane. If you want to frame thicker materials, please change the insertion depth in the frame configurator according to your wishes. The adjustment is free of charge for you.
Example: You would like to frame a picture in normal paper thickness in a folding passepartout in 3 mm thickness with 0.75 mm thick back wall cardboard: In this case you order the frame with an insertion depth of 4 mm (the frame usually offers a little more space than the ordered 4 mm in this example).
Tip: Select the insertion depth as precisely as possible. If the insertion depth is too large, there will be a gap between the glass pane and the frame profile after the magnetic assembly of the frame and there will be no glass pressure. In this case, you can subsequently insert background cardboards for "filling". Many customers also use this option specifically in order to be as flexible as possible in the long term with regard to the material thickness when exchanging images.
Depending on the variant, a 10 or 20 mm high spacer between the rear wall and the glass pane is integrated into the frame of the distance magnet frame. This "distance" should not be confused with the insertion depth. The four distance strips are magnetically equipped and can be easily removed. The photo shows the basic element without the 10 mm high strips.
The four distance strips keep the glass pane at a distance to the picture or to the rear wall cardboard, which is always part of the basic element of the distance magnetic frame. For this frame type, insertion depth means: An additional cardboard, a picture or a passepartout can be inserted under the magnetic distance strips, for example - standard thickness up to 2 mm. However, if you would like to insert a thicker material under the distance strips, please select the appropriate insertion depth in the frame configurator.
Example: You have mounted a three-dimensional object floating on a 3 mm thick museum cardboard and want to frame it without contact to the glass pane. If your mounting box is the same size as the glass pane (=order format), order the frame with an insertion depth of 3 mm.
Tip: The basic element of the distance magnetic frame does not have a hard foam plate as a surface for the picture mounting, but is supplied as standard with a Klug museum cardboard: for formats < 500 x 600 mm, the background cardboard is loose or from 500 x 600 mm fixed in the middle on the back wall to prevent the cardboard from bulging forward. As an option, the back wall carton can also be supplied loose for larger order formats. If you mount the art on an additional cardboard instead of directly on the back wall cardboard in the basic element, the exchange of your work is particularly easy.
In contrast to the Classic magnetic frame, the B1 magnetic frame does not use a rigid foam plate in the basic element, but a white coated aluminium is used - this makes the frame flame-resistant and meets the requirements of DIN 4102-1.
The image is placed directly on the surface of the white aluminium or optionally on an additional background cardboard. If you need more than 2 mm insertion depth for your picture or passepartout, you can also increase the insertion depth of the fire protection picture frame in the configurator according to your wishes. The metal components of the B1 basic element are then adapted exactly and without additional costs for you.
Example: You use the B1 magnetic frame for escape and rescue plans and have previously hung these on a 5 mm thick plate material in the corridors. Order the frame with an insertion depth of 5 mm and present it attractively framed without having to reprint your plans.
Tip: The fire protection picture frame is usually used with the standard insertion depth of 0-2 mm, for presentations with or without passepartout. Optionally, up to 9 mm insertion depth is possible - interesting for laminated prints or if you want to insert a spacer into the frame.
The basic element of the Conservo magnetic frame consists of a steel sheet angle frame and a loosely inserted KLUG cardboard.
The frame offers many useful options - especially with regard to the insertion depth: the stable cardboard is not glued to the sheet metal angle composite, but can be loosely removed and replaced by other material, for example a thinner cardboard. This means that the standard insertion depth of 0-2 mm can be increased retrospectively by inserting thinner materials - even if you have not yet considered choosing an increased insertion depth when ordering.
Example: You would like to use the frame for changing exhibitions. The maximum material thickness of your pictures/passepartouts is 4 mm, plus a 5 mm high D5 insert frame as a spacer to the glass pane. In this case you order the frame with 9 mm insertion depth instead of the standard insertion depth of 0-2 mm.
Tip: The Conservo magnetic frame can be ordered with up to 16 mm insertion depth, depending on the frame profile. In order to keep the use of the frame as flexible as possible in the long run, many customers like to order this frame type with a particularly large insertion depth. KLUG cardboard or museum cardboard, both available in different thicknesses, are suitable as compensation for filling.
The basic element of the Protect magnetic frame consists of a number of components that are very precisely matched to each other. It is, so to speak, the core of the frame and forms the basis for the airtight Protect picture frame.
The basic element consists of several levels with a surrounding integrated seal. This construction results in an insertion depth of 9 mm (exception: with glass type Mirogard Protect = 8 mm). The frame offers sufficient space for the particularly demanding assembly of works of art - often used in combination with the 5 mm high D5 insert frame as a spacer to the glass.
Example: You order the Protect magnetic frame with the optionally available D5 insert frame. In this case, 4 mm insertion depth remains under the 5 mm high spacer for the picture montage.
Tip: The basic element is made of anodised aluminium similar to a tub inside. Inside is a 6.5 mm thick Klug cardboard with recesses for ProSorb, thermohygrometer and a data logger/measuring probe (optional). A 1.5 mm thick museum cardboard box is always included. The insertion depth of 9 mm can be achieved by removing the cardboard supplied and replacing it with your material. If you leave the cardboard in the frame, the insertion depth between the cardboard surface and the glass pane is 7.5 mm.
The magnetic display frame is the alternative to simple folding frames. Similar to the Classic magnetic frame, the basic element is a composite of a PAT-tested hard foam plate and a steel sheet angle frame and is firmly screwed to the wall.
With this frame type, a Posterfix module is integrated into the basic element at the top edge. Due to the clamping effect, the poster holds by itself. There is no insertion depth in the narrower sense with this frame. The poster can have a thickness of up to 0.25 mm so that the principle works perfectly. This corresponds to paper with a basis weight of approx. 300 g/qm.
Example: You have your posters printed on 250g offset paper. The Posterfix module adapts to the paper thickness by means of a spring mechanism and holds the poster securely. When ordering, you choose whether the frame is used in portrait or landscape format. Accordingly, the Posterfix module is placed in the frame.
Tip: Use the flatness properties of the rigid foam board for the optimal presentation of your posters. The higher the grammage and the better the flatness properties of the paper, the more perfect the result at the point of sale. Tell your service provider for the printing of the posters which maximum grammage/paper thickness is possible.
