The use of vertical space in the kitchen is not just a trend, but a necessity, especially in small apartments. The space above the refrigerator often remains empty, turning into a dust collector, although you can organize a full-fledged storage system there for rarely used dishes, workpieces or household appliances. Creating a mezzanine or a full-fledged pencil case above the unit allows you to visually extend the kitchen and add several tens of liters of useful volume.
However, before taking up the tools, you need to understand that a refrigerator is a complex technical device that requires special operating conditions. Improper design can disrupt air circulation, which will lead to overheating of the compressor and failure of the equipment. In this article we will look at all the intricacies of design, selection of materials and safe installation of furniture above the refrigerator.
It is important to immediately decide on the type of construction: will it be a built-in cabinet covering the top of the unit, or a separate mezzanine shelf hanging above the level of technology. Not only the aesthetic qualities of your kitchen, but also technical parameters future furniture depend on this choice. Let's look at the key aspects that cannot be ignored when planning work.
Calculating dimensions and choosing the type of structure
The first step in creating any furniture structure is accurate measurement. You will need a tape measure, a pencil and a level. Measure the height of the refrigerator from the floor to the highest point, not forgetting to take into account possible unevenness of the floor. The distance between the top of the equipment and the ceiling should be sufficient not only to place the cabinet, but also to provide a ventilation gap ventilation gap.
If you plan to make a built-in cabinet that will tightly fit the body of the refrigerator, the depth of the furniture should be at least 5-10 cm greater than the depth of the unit itself. This is necessary so that the refrigerator doors can open unhindered, without touching the cabinet walls. In the case of built-in modelswhich initially assume the presence of a furniture facade, the requirements for gaps may differ and are regulated by the manufacturer's instructions.
There are two main types of structures for placement above the refrigerator. The first option is a blank box with hinged or sliding doors that hides the contents from view. The second option is an open shelf with sides, which looks lighter visually, but requires perfect order on the shelves. The choice depends on what exactly you plan to store there: heavy cans of preserves or light kitchen items.
When calculating the width of the cabinet, remember that the side walls should not fit tightly to the sides of the refrigerator if they are in the heat exchange zone. Usually the compressor and condenser are located at the back, but in some models heat transfer occurs through the side walls. Thermal gap on the sides should be at least 2-3 cm on each side.
Selection of materials and preparation of tools
For making a cabinet above the refrigerator, most often use laminated particle board (LDSP). This is an affordable, durable and easy-to-process material, which is available in a huge number of decors. For wet rooms, such as a kitchen, it is important to choose boards with a moisture resistance class of at least E1 or E0.5.
An alternative to LDSP can be solid wood or MDF. MDF is more environmentally friendly and holds fittings better, but is more expensive and harder to process at home. If you are making an open shelf, you can consider tempered glass or durable plastic, but these materials are less suitable for heavy loads. Load-bearing capacity material is a critical parameter, especially if you plan to store heavy equipment or food supplies there.
⚠️ Attention: Do not use drywall to create shelves inside a cabinet or load-bearing structural elements above a refrigerator. This material will not withstand vibration from the operation of the compressor and can be deformed due to temperature changes.
For assembly you will need a standard set of tools: an electric drill, a screwdriver, wood drills, a tape measure, a square and a level. If you plan to cut laminated chipboard yourself, you will need a jigsaw with a file for a clean cut, but it is better to order cutting and edging of the ends in a specialized workshop. A high-quality edge will protect the slab from moisture and give the product a finished look.
Also, do not forget about the fittings. For wall cabinets, adjustable hinges with closers are best suited, which will allow you to accurately align the facade. If the cabinet is wide, additional shelf holders and, possibly, reinforced canopies will be required that can support the weight of the structure along with the contents.
Ensuring proper ventilation
The most important technical aspect when installing furniture above the refrigerator is organizing air circulation. The refrigerator works on the principle of a heat pump: it takes heat from the internal chamber and throws it out through a condenser, located, as a rule, on the back wall. If this process is disrupted, operating efficiency will decrease and energy consumption will increase.
Ideally, there should be an air gap of at least 10-15 cm high above the refrigerator, if the cabinet is not built-in. If you are making a box that completely covers the upper part, you need to provide ventilation holes. They can be located in the top lid of the cabinet (if it is far from the ceiling) or in the back wall of the structure.
Calculation of the area of ventilation holes
To ensure natural draft, the area of the inlet and outlet openings must be at least 200 cm² (for example, 20x10 cm). If the holes are smaller, the circulation will be insufficient.
There is a common misconception that modern refrigerators do not need ventilation from above. This is true only for models with forced circulation and a forward-facing condenser, but even in this case, manufacturers recommend leaving a gap. Compressor overheating is the main reason for shortening the service life of refrigeration equipment.
To improve draft, you can use special ventilation grilles mounted in the bottom or lid closet If the cabinet is deep, sometimes it makes sense to install a quiet duct fan that will force air through, but this requires an electrical supply and complicates the design.
Step-by-step instructions for assembling the cabinet
The assembly process begins with preparing the parts. If you ordered a cut, you should have ready-made elements on hand: two side panels, top and bottom covers, a back wall (made of fiberboard or chipboard) and shelves. Check the dimensions according to your drawings. It is most convenient to assemble on a floor covered with soft material, so as not to damage the laminate.
First, we assemble the main frame. Connect the sides to the bottom and top covers. For strength, use furniture ties (Euroscrews) or confirmats, having previously drilled holes with a drill with a diameter of 4.5 mm for a confirmat drill. It is better to nail the back wall or screw it with self-tapping screws around the perimeter, as well as in the center for rigidity, if the material allows.
☑️ Assembly checklist
Next we install the internal filling. The shelves can be mounted on stationary shelf holders or used adjustable ones to change the height of the compartments if necessary. If the design includes drawers or sliding mechanisms, their installation requires special precision to avoid distortions.
The last stage of assembly is the installation of facades and fittings. Hang the doors onto the frame, but do not tighten the screws all the way. Adjust the door height, depth and plane using the adjusting screws on the hinges. Make sure that the gaps between the doors are uniform, and that they themselves close tightly and without distortions.
Installation of the structure and fastening to the wall
Installing a finished cabinet above the refrigerator is a crucial moment that requires the participation of an assistant, since the structure can be heavy. Before installation, make sure that the refrigerator is level and stable. If the cabinet is wall-mounted, you need to find a load-bearing wall or use special dowels for hollow structures if the wall is plasterboard.
For fastening, use a mounting strip (hanging rail). It is attached to the wall horizontally at a level, and the cabinet itself is hung on the counter part. This makes it easy to adjust the height and fit. If the cabinet is tall and stands on the floor (pencil case), it is still recommended to attach it to the wall through the top to avoid tipping over.
| Wall type | Fasteners | Drill diameter | Point load |
|---|---|---|---|
| Concrete / Brick | Dowel 6x40 or 8x50 | 6 mm or 8 mm | up to 40 kg |
| Hollow brick | Butterfly dowel or long dowel | 6 mm | up to 20 kg |
| Drywall | Driva or Molly dowel | Depends on the dowel | up to 15 kg |
| Air block | Chemical anchor or special. dowel | 8 mm | up to 25 kg |
When fastening, it is important not to damage communications that may pass inside the wall. Use a hidden wiring detector before drilling holes. If the cabinet is built-in and covers the top of the refrigerator, make sure that it does not rest on the lid of the unit, but stands on its own legs or is suspended above.
⚠️ Attention: Never use the top cover of the refrigerator as a load-bearing surface for the cabinet. It is not designed for such loads and can bend, damaging the insides of the unit.
Decoration and finishing touches
After the cabinet is installed, you can begin to decorate it. If laminated chipboard was used, then, as a rule, no additional decor is required, except for installing handles. You should choose handles that are comfortable and safe so that you don’t hit your head on them when walking past the refrigerator. Mortise shell handles or Gola profile are good options.
If the cabinet is too massive and visually “presses”, you can lighten it by adding LED lighting under the lower part. This will create a floating effect and make the kitchen cozier. For lighting, use LED strip with moisture protection IP65 and a power supply with power reserve.
The interior space can also be adapted to specific needs. To store cans and bottles, you can make special cutouts in the shelves or use organizers. If the cabinet is used to store equipment (for example, a multicooker or bread machine), make sure that the socket is in an accessible place and the cable does not overheat.
Regularly check the condition of the fasteners and hinges, especially in the first months of operation. Under load, the structure may “settle” a little, and adjusting the hinges will help return the doors to their ideal position. Caring for the cabinet is standard: wiping with a damp cloth and using mild detergents.
Frequently asked questions
Is it possible to completely sew up a refrigerator into a cabinet from all sides?
It is impossible to completely sew up a refrigerator, especially older models. Gaps for air circulation are required. Built-in refrigerators have a special ventilation system at the front, but they also require compliance with the gaps specified in the instructions.
What is the minimum gap between the refrigerator and the cabinet?
The minimum gap at the top is 10-15 cm for natural ventilation. On the sides, if there are heat exchangers there, - at least 2-3 cm. Always look at the exact numbers in the technical data sheet of your model.
Will the cabinet interfere with opening the refrigerator door?
If the depth of the cabinet is calculated correctly (refrigerator depth + 5-10 cm), the door will open freely. If the cabinet is made flush with the refrigerator, the door can rest against the cabinet wall when opened 90 degrees.
Is it necessary to make a back wall for the cabinet above the refrigerator?
The back wall is desirable for structural rigidity and protection from dust, but it should not block the path of air to the condenser. Often, a cutout is made in the back wall or perforated material is used.
Will the shelf above the refrigerator support heavy objects?
It depends on the material of the shelf and the method of its fastening. 16 mm thick laminated chipboard with a span of more than 60 cm can bend under weight. For heavy loads, use a thickness of 25-32 mm or install additional supports (partitions).
