Eco Materials — What You Need to Know Before Buying

The trend toward all things natural and environmentally friendly is reflected in modern construction approaches too — new natural materials and "green" technologies are increasingly used to build residential homes. Customers are willing to pay more when they know natural materials and energy-saving technologies are used in their home — and builders are increasingly taking this into account.

But before choosing eco materials for your home, it's worth honestly understanding a few practical questions — how much it costs, how durable it is, and what "biodegradable materials" actually means.

What are biodegradable materials

Construction waste that breaks down on its own in a short time, doesn't harm the environment and doesn't require significant disposal effort — sounds like fantasy, but today it's reality.

Biodegradable materials help avoid creating huge landfills and don't pollute soil and water bodies with harmful chemical compounds. This isn't about some new technological inventions, but rather a new perspective on familiar materials — clay, straw, natural dyes.

For example, synthetic paints can easily be replaced with a mixture of mineral pigments, egg white and lime — and such a coating is in no way inferior in quality to many conventional paints.

Natural insulation materials

Given the cost of energy and the size of utility bills, energy efficiency becomes one of the key considerations when building a home. There are many examples of using reed insulation, wood wool, pressed straw, cellulose and cotton as thermal insulation materials — in quality and effectiveness they are not inferior to the best commercial products.

Many natural insulation materials contain up to 80–85% recycled material, making their production maximally eco-friendly.

Rammed earth as a building material

The use of rammed earth in construction goes back many centuries — homes were built using earth blocks even in ancient times. The production process for such blocks differs little from what was used centuries ago: earth combined with gravel and clay particles is compressed into strong blocks, which set and can be used like bricks — just like pressed straw and wood wool blocks.

Such homes achieve optimal thermal regulation — warm in winter, cool in summer. Moreover, this construction method generates significantly fewer emissions than traditional techniques.

How much does sustainability cost

The honest answer is that eco materials often cost more to purchase than traditional alternatives. Pressed straw, hemp insulation or clay plaster typically require more careful raw material processing and are still produced on a smaller industrial scale than concrete or mineral wool, which affects the price.

But the comparison shouldn't be the one-time cost of the material, but the total cost of owning the home over decades.

Natural insulation materials — straw, hemp, wood wool, cellulose — have high energy efficiency, which reduces heating and cooling costs throughout the building's service life. A home built with quality natural insulation requires less energy to maintain a comfortable temperature — meaning the higher initial material cost is offset by lower heating bills every year.

Furthermore, many natural materials are made from recycled raw materials — up to 80–85% of such insulation can consist of recycled material, which reduces production costs compared to materials requiring extraction and processing of raw materials, such as mineral wool, which is produced by melting minerals at temperatures above 1000 degrees.

The conclusion is simple: natural materials are an investment with delayed returns. They cost more at the purchase stage but reduce a home's operating costs for years to come.

How durable are natural materials

The main fear of people encountering the idea of eco construction for the first time is "won't the straw rot, won't the clay get washed away after a few years?" This is a reasonable question, and it has an answer proven by time.

Rammed earth as a building material has been used for many centuries — homes were built using earth blocks even in ancient times. The principle of producing such blocks has barely changed over the centuries: earth combined with gravel and clay particles is compressed into strong blocks, which set and serve like bricks. Homes built this way centuries ago have, in some cases, survived to this day — this is not theory, but historical fact.

Pressed straw, protected with clay or lime plaster, also demonstrates durability measured in decades when properly installed and protected from constant moisture. The key condition is following the correct technology — protecting the facade from direct rain exposure and proper foundation waterproofing.

Homes made from natural materials also provide natural thermal regulation — coolness in summer and warmth in winter — which also reduces mechanical and temperature stress on the structure compared to buildings where indoor temperature fluctuations are sharper due to less effective insulation.

In other words: with proper construction, natural materials are no less durable than traditional ones, and in some cases — such as rammed earth — their durability is confirmed by centuries of real-world use, not just laboratory tests.

What materials we offer

If you're considering eco construction or renovation, we offer hemp insulation in various densities, flax insulation, sheep wool insulation and other natural materials — each suited for different tasks, from roof insulation to wall soundproofing.

Frequently asked questions

Do eco materials really pay off?
Yes, through reduced heating and cooling costs throughout the home's service life — the total cost of ownership is often lower than with traditional construction.

How long do straw and clay homes last?
With proper installation and moisture protection — decades. Rammed earth as a material has been used for centuries, and a number of such buildings have survived to this day.

Are eco materials really more environmentally friendly?
Yes — many are made from recycled raw materials (up to 80–85% of their composition) and don't require energy-intensive processing like mineral wool does.
