Owners of apartments in old buildings often face a dilemma: what to do with the niche under the window in the kitchen, popularly known as Khrushchev refrigerator. This architectural element, conceived by engineers to store food in winter without the use of electricity, in modern conditions often becomes a source of drafts and heat loss. However, simply sealing it tightly is not always the best solution, because with the right approach, this niche can become a stylish and useful element of the interior.
Before starting work, it is necessary to assess the technical condition of the structure and determine the functional purpose of the object. Soviet refrigerator can be converted to a full-fledged cabinet, a place to install a sink, or even a decorative niche, but each option requires a specific approach to insulation and finishing. It is important to understand that the outer wall in such houses is usually thin, so issues of thermal insulation and waterproofing should be given priority attention.
In this article we will look in detail at how to refine a niche under a window, what materials are best suited for interior decoration and how to avoid common mistakes. The correct one reconstruction will not only improve the aesthetics of the kitchen, but also increase the energy efficiency of the room by getting rid of cold bridges. Let's consider the options available for implementation with your own hands without the involvement of expensive construction teams.
Audit of the condition of the niche and preparation for work
Any reconstruction begins with a thorough analysis of the current condition of the object. The Khrushchev refrigerator is essentially a recess in the brickwork with a thin inner wall, which is often only half a brick thick. The first step is to dismantle the old wooden doors and shelves, if they remain. Often, traces of mold, condensation or destruction of the plaster layer are found underneath.
Particular attention should be paid to the ventilation hole, which in the original design was led into the ventilation duct to circulate cold air. If you plan to turn the niche into a warm closet, this hole will have to be sealed. If it is designed summer kitchen with natural cooling, the channel must be cleaned and equipped with adjustable dampers.
- 🔨 Check the strength of the brickwork: tapping will help identify voids or cracks.
- 💧 Evaluate humidity level: the presence of mold requires mandatory treatment with an antiseptic.
- 📏 Measure the exact geometric parameters to order furniture or materials.
⚠️ Attention: When dismantling old structures, be careful with electrical wiring. In old houses, wires were often laid chaotically, and a junction box or hidden cable may be hidden in a niche.
After cleaning the niche from debris and old finishing materials, the surface must be primed. This will improve the adhesion of subsequent layers of plaster or insulation. If the brickwork has deep seams or damage, they must be repaired with cement mortar. Only after preparing the base can you proceed to choosing an insulation strategy.
Choice of strategy: insulate or leave it cold
The key question that faces the apartment owner is whether to maintain the function of a winter refrigerator or turn the niche into part of the living space. The decision depends on the climate zone and personal preferences. Preserving the function natural cooling is relevant for regions with long and cold winters, where this allows you to save energy and store supplies of pickles.
If you choose the option with cold, then the inside of the niche is not insulated, but, on the contrary, leaves contact with the street. However, modern requirements for energy efficiency dictate their own rules: even in this case, it is recommended to install high-quality thermal insulation of the door. For the “warm cabinet” option or installing a sink, you will need complete insulation of the back wall and side surfaces.
