How to insulate walls thermally and sound-wise without extensive renovations?

Many apartment and house owners face problems with cold walls and extraneous noise from neighbors or the entrance hall, but aren't prepared for a major renovation involving demolition, dust, and significant costs. The good news is that thermal and sound insulation can be improved without a complete renovation using modern finishing materials. One such solution is Bioplast liquid wallpaper.

In this article, we'll look at how wallpaper can make a room warmer and quieter without the need for complex construction work.

Is it possible to improve thermal and sound insulation without major repairs?

Yes, it's possible. There's not always a need to install drywall, mineral wool, or foam. These solutions:

• reduce usable area;
• require removal of the old coating;
• require significant financial and time expenditures.

Liquid wallpaper is a decorative finishing coating that also serves as an insulating layer without requiring complex repairs.

How does liquid wallpaper affect thermal insulation?

Liquid wallpaper TM Bioplast has a fibrous structure, which includes:

• cellulose fibers;
• silk fibers.

Thanks to this coating:

• forms an additional heat-insulating layer;
• reduces the feeling of a "cold wall";
• helps retain heat in the room.

The effect is especially noticeable in apartments with corner walls, on the ground floors or in older buildings.

Does liquid wallpaper really reduce noise?

Yes, liquid wallpaper has sound-absorbing properties. Its soft, cellular structure:

• reduces sound reflection;
• conceals household noises;
• reduces the audibility of conversations, television, or footsteps from adjacent rooms.

Of course, this is not complete noise insulation, as in professional acoustic systems, but for apartments and offices the effect is quite noticeable.

What are the advantages of liquid wallpaper over other materials?

Liquid wallpaper TM Bioplast combines several functions:

• decorative coating;
• thermal insulation;
• soundproofing;
• leveling minor wall defects;
• seamless surface without joints;
• maintainability.

Do I need to prepare the walls before application?

Surface preparation is minimal. Walls must be dry and clean. Before applying liquid wallpaper, it is recommended to treat the surface with a white, deep-penetrating acrylic primer. You can also purchase Aquablock acrylic primer concentrate in our store.

The ease of preparation is another reason why liquid wallpaper is ideal for updating interiors.

How is liquid wallpaper applied?

The process is simple and accessible even without experience:

1. The dry mixture is soaked in water according to the instructions.
2. The material is infused.
3. Liquid wallpaper is applied to the wall with a trowel.
4. A uniform, seamless layer is formed.

Is it possible to apply liquid wallpaper partially without renovating the entire room?

Yes, this is one of the key advantages. You can:

• decorate only the cold or noisy wall;
• update one area (for example, near the bed or work area);
• combine liquid wallpaper with other finishing materials.

Is liquid wallpaper safe for residential premises?

Yes. Bioplast TM products are:

• ecological;
• has no smell;
• suitable for bedrooms, children's rooms and offices;
• does not create a greenhouse effect.
