How to choose insulation for your home — a complete guide
Choosing insulation is one of the most important decisions when building or renovating. The right choice affects not only warmth in the home, but also comfort, heating costs and even the health of the occupants. Poorly chosen insulation is difficult and expensive to replace — which is why it's important to get it right from the start.
Many people make the mistake of choosing insulation solely on price or thickness. The result is predictable — cold walls, high heating bills, moisture, mould and noise from neighbours. The good news is that with the right choice, all of these problems can be avoided.
What you need to know before choosing
Before selecting a material, it's important to answer three questions:
— Where will the insulation be used — walls, ceiling, floor, roof or partition structures?
— What problem needs to be solved — heat loss, noise from neighbours or moisture?
— What is the building structure — new or old, brick, concrete or timber?
The answers to these questions determine the type of insulation, the thickness and the installation method. A universal solution suitable for all cases does not exist — every project is different.
Main types of insulation
Thermal insulation
Thermal insulation reduces heat loss through walls, roof and floor. The key indicator here is the thermal conductivity coefficient λ (lambda) — the lower it is, the better the insulation. When choosing thermal insulation, the thickness of the layer, the vapour permeability of the material and its moisture resistance are also important.
Good thermal insulation reduces heating costs by 30–50 percent depending on the type of building and the climate of the region.
Sound insulation
Sound insulation solves the problem of noise — from neighbours, the street or appliances. It is important to distinguish between two types of noise:
Airborne noise — conversations, music, television. Reduced using absorbent materials with a high sound absorption coefficient.
Impact noise — footsteps, vibrations, knocks. Reduced using materials with high mass and elasticity, placed between structural layers.
Correct sound insulation can reduce noise levels by 40–70 percent.
Eco insulation
Eco insulation materials combine excellent technical characteristics with ecological cleanliness. They are made from natural raw materials, are biodegradable and do not release harmful substances. They also naturally regulate humidity, which prevents the formation of mould and maintains a healthy microclimate in the rooms.
Recommended materials
Cotton Antisound is a textile sound and thermal insulation made from recycled cotton. It effectively absorbs airborne noise, improves acoustics and is completely safe for residential spaces. Suitable for walls, ceilings and partition structures in apartments, offices and studios.
Polyest Antizvuk is a modern acoustic insulation made from polyester fibres with high noise reduction effectiveness. Moisture resistant, long-lasting and suitable for walls, ceilings and complex building structures.
Hemp insulation is a natural material with excellent thermal insulation properties. It regulates moisture biologically, prevents mould and creates a healthy microclimate. Suitable for walls, roofs and floors.
Flax insulation creates a soft and healthy microclimate in living spaces. Natural, breathable and durable — ideal for people seeking eco solutions for the home.
Sheep wool insulation provides natural protection from cold and noise. It regulates moisture and improves indoor air quality.
How to make the right choice
Identify the problem — heat loss, noise or moisture.
Choose the material suitable for the specific problem and construction.
Consider thickness, installation method and vapour permeability.
Trust a specialist for more complex projects.
Combining thermal insulation, sound insulation and vapour permeability in one layer is the most effective approach for achieving a balanced and healthy home environment.
Frequently asked questions
Which insulation is best?
There is no universal answer — the choice depends on the type of noise or heat problem, the wall structure and the budget. Cotton Antisound is an excellent choice for soundproofing apartments, while hemp insulation is ideal for eco construction.
Can insulation be installed without major renovation?
In most cases — yes. Many materials can be mounted on an existing wall without any destructive work.
How much does insulation reduce heating costs?
When correctly installed, the reduction can reach 30–50 percent depending on the type of building.
