Thanks to a number of positive qualities, material is demanded both for insulation works – to fill air gaps, and to insulate floor and internal walls.

HK35 or styrene granules is an environmentally-friendly, high-grade thermal insulation material made in Germany, with the latest and most advanced technology used. HK35 granules are especially suited for insulation of old buildings – apartment houses, private houses, and public buildings built until 1940, as well as Khrushchev-era buildings, which are characterized by double exterior wall constructions. Styrene granules completely fill in air gaps, cracks and empty holes in the walls, effectively eliminating heat loss and thus significantly reducing heating costs.
HK35 has convincingly passed all necessary safety and quality checks, and has received certification in accordance with European Union quality and environmental standards.

What does H35 consist of?
HK35 is graphite-treated granular foam polystyrene (70%), which has been added to the crushed polystyrene particles (30%). Graphite has an excellent moisture rejection capability as well as material slipperiness in the process of application. Thanks to the combination of HK35 components protected by the European patent, it is possible to fill in all the smallest cracks in the outer wall constructions, thereby preventing the slightest entrance of the cold air indoors, through the insulation process of the building. Thermal insulation cannot be effective enough using granules only.

Thermal insulation process
Styrene granules are applied by blowing method. With the help of a high-pressure heat insulation material blowing equipment, styrene granules are sprayed between the layers of outer walls of the building, thus thoroughly filling all cracks and empty holes in the walls while maintaining building’s ability to “breathe”.

Thermal insulation with HK35 is very convenient. It can be carried out both from the inside of the building and from the outside as well as in hard-to-reach places, and without disassembling the facade – It is only necessary to create bores in the outer wall of the building, which will serve as channels for filling air gaps with styrene granules. Typically, bores are made in such a way so that aesthetic qualities of the building would be less affected, for example, in brick seams. At the end of the thermal insulation process, bore or channel is filled and disguised without leaving visible traces on the facade of the building. It is possible to insulate a significant part of the exterior wall through a single borehole or channel.

Thermal insulation using styrene – HK35 granules is not only fast and convenient, but also economical and environmentally friendly. The working process is clean, does not create surpluses in the process, and
thermal insulation material is recyclable.

Parquet installation step by step

Parquet flooring installation and repair

Lacquered and oiled parquet floor maintenance

At your feet - high-quality parquet with a lacquered or oiled surface, which perfectly protects it from dirt.

Parquet floors are subject to different loads, depending on their exploitation. Over time, signs of wear will be visible on the parquet floor. Even very hard flooring is not protected from that. Therefore, we recommend that you regularly take care of the floor.

To protect the floor from scratches, place felt lining under the furniture (especially under tables and chairs). Place a special polycarbonate mat under the office chair. Put a rug in front of the door, otherwise sand and dirt will act on the floor like sandpaper.

Indoor climate
Provide good climatic conditions for parquet. The temperature of 20-22 degrees and the relative humidity of 50-65% will not only improve your well-being, but will also create an ideal environment for the wooden floor. A healthy indoor climate will support the value of a parquet floor and protect it from electrostatic charge. Of course, the rooms need not only to
be heated, but also to be ventilated regularly – especially in new houses, where there is an increased level of humidity due to not dried walls and floor coverings. In such cases, an air humidifier may be temporarily needed.

Underfloor heating
Parquet flooring and floor heating – are they compatible? By experience, we can say – yes – and this even has some advantages. If it is applied correctly, then rooms with underfloor heating have more stable climate than rooms that are heated by radiators.
The resistance of the thermal conductivity of three-layer parquet is small. This means that the thermal conductivity is not delayed. Therefore, heated parquet flooring is a good solution. Of course, one must bear in mind that such wood as beech, ash and maple reacts to changes in humidity more quickly than, for example, oak. Therefore, please observe the climatic indicators mentioned above. If they keep staying within these limits, it guarantees a long service of the parquet floor. If you use underfloor heating, we recommend that you glue the floor.

Varnished parquet flooring

For daily cleaning at home, it is enough to clean the floor with a damp cloth or simply vacuum with a vacuum cleaner. To clean very dirty floors, you will need to use special cleaners. Do not soak the parquet, because it can damage the floor.

There are special products for care and protection of varnished parquet and wood floors.
They restore the old layer of varnish, protect it and give it a slight sheen, and also form a moisture-repellent surface.
Before use, the floor must be clean; it should not have a wax or other layer other than varnish.

Oiled parquet floors
For daily cleaning at home, it is enough to clean the floor with a damp cloth or simply vacuum with a vacuum cleaner. To clean very dirty floors, you will need to use special cleaners. There is a highly effective, concentrated cleaner for easy and thorough cleaning of oiled parquet floors. The product does not form too much foam, so it can be used in washing machines. When washing the floor with this product, it is simultaneously cleaned and restored; the surface becomes more resistant to wear. The cleaner does not form a film.
Regular maintenance of the floor prevents slipping.
Correct dosage: 2 - 3 caps per 1 liter of water.
Wash the floor with a damp (not wet) cloth only.

In case of heavy loads, protect the floor from time to time. This is intended for floors with heavy loads and often washable floors, as well as for oil renewal. For protection, apply a small amount of the product on a cloth and wipe the floor with it. Allow it to dry and then polish the floor again. You can be sure that this eco-friendly floor cleaner won’t sacrifice the
strength of the parquet.

Recommendations for the frequency of parquet care

Varnished parquet flooring:
- floors with a small load (in the bedroom and living room) - once a year
- floors with medium load (corridor, staircase, office) 1 - 2 times a month
- floors with heavy loads (restaurant, shop, school) once a week

Oiled floors:
- floors with a small load (in the bedroom and living room) - 1 - 2 times a year
- floors with medium load (corridor, staircase, office) 1 - 2 times a month
- floors with heavy loads (restaurant, shop, school) once a week

Important notes about varnished parquet flooring
Intensively used parquet in offices, restaurants, dance halls, etc. – we recommend to polish the upper part of the varnish and re-apply a new layer of varnish (depending on wear, you can apply two layers) once a year, preferably in August, to prolong the service of a parquet.
At home, the need to apply a new layer of varnish appears after 5-15 years, depending on the load and the requirements for the appearance of the floor.

Cleaning of the most common stains
Wine, fruit, berries, juices, cream, non-acoholic beverages, beer, coffee, tea – household cleaning products
Shoe polish, black stripes from shoes, tar, oil, grease, chocolate – petrol
Ink, lipstick – ethyl alcohol
Blood – cold water

Building insulation

Ecowool is a high-quality, breathable thermal insulation material used for insulation of residential and industrial buildings, more precisely, for the insulation of walls, ceilings and floors. The material is made from recycled paper, and because of its eco-friendly properties it is called ecowool.
Ecowool is easily and quickly installed on all types of slopes and building structures by blowing or spraying. Ecowool effectively fills all the cracks, leaving no free millimetres, like stone and glass wool. Ecowool also protects the master's hands from itching.

Ecowool is an environmentally friendly and natural wood fiber made from recycled paper. Natural wood fiber provides moisture control of the material and it breathes. Paper processing saves natural resources and does not pollute the environment, as it does not create waste.
Ecowool is an effective material for thermal insulation (λ = 0.039-0.041W / mK).

The raw material of the product – natural wood fiber – provide its thermal insulation properties, as well as makes the material light, with a fine-grained structure and high air permeability. Ecowool is easily and quickly installed on horizontal, vertical and inclined surfaces, filling all the cracks and providing high thermal stability. In buildings where ecowool is used, there is no need to use building films for condensation, as ecowool regulates humidity naturally.

"BTRS" implements thermal insulation of buildings with thermal insulation materials

With ecowool, it is possible to insulate the building:
from the inside – dry and wet installation
from the outside – dry and wet installation

Wet installation is used in open structures.
Material is sprayed in a wet form or is firmly installed with special equipment for application even in hard-to- reach places. After drying, the material is firmly attached to the surrounding surfaces, which prevents possible deformation of the surface.
In addition, inserting ecowool in wet form can fill even the narrowest cracks, leaving no gaps for the wind.
After the drying of ecowool, the surface is polished to make it smooth and ready for further processing.

Dry installation is used in horizontal and inclined structures, for example, on floors or on a slope of a roof. Dry insulating material is blown into the slots and fills even the smallest structural slits. With the method of dry build-in, it is possible to fill various gaps in the walls of buildings (for example, between gypsum boards), making defects into warm effects.

Installation of ecowool is carried out with special equipment. The material is sprayed onto the surface with the help of equipment (wet installation) or blown by compressed air into pre-prepared structures (dry installation).
