Types of wood floor


Types of wood floor

Wood flooringWood is a marvelous natural material. Comfort and warmth of wooden floorings are unique. They do not go out of fashion; moreover as time goes by they become more beautiful and create a special feeling of coziness. Their artificial imitations are quite good - at accessible prices that make their replacement easy if the flooring is old or simply because it bores you.

The Royal origin of the parquet

Natural wood flooringHere is some history. Wood has been used for floorings in India, Egypt and China for the first time in the Middle Ages but only the wealthy people could afford it. In the 16th century the French started to place small wooden tiles made of spruce in the Palaces of Versailles, Sanssouci and the Louvre. They called their creation “parquet” which means a “small park”. Frederick the Great named the parquet “Royal” flooring because almost by the 18th century parquet flooring was found only in the palaces. Nowadays, due to modern technologies parquet is very popular and everyone can afford it or at least a good imitation (laminated flooring)

Natural wood

Natural wood has enough strength, long life, good thermal and sound insulating properties as well as a specific wood grain. The most popular parquet here is usually made of solid deciduous trees such as oak, beech, ash-tree, maple, walnut-tree, cherry-tree, etc. The most important properties are: grain and wood’s wear stability that is related to the rigidness and to the extent of thickness of the material. Different kinds of oak have an extent of thickness between 820-850 kg/m3, beech is in the same range, walnut - around 789 while the coniferous trees’ thickness varies from 450 to 570 kg/m3.

Natural wood

Usually the parquet that can be found on our market is in the following variations: massive/solid parquet; layered parquet (two-, three- or multilayered); the new parquet “Selenio’ and finally the well known laminated flooring. Each kind of them has its advantages and disadvantages but the price, stability, labor-consumption of fitting and conditions for maintenance are the ones that are most important.

Massive parquet

Massive parquet woodflooringMassive parquet is number one of the kind due to its perfect heat insulation and its stability. It is comparatively easy to be maintained, also is has an ideal appearance and moreover it has a very long life if it is properly fitted and well maintained. No doubt fitting is the most difficult and risky part related to this kind of flooring. Most important here is the base – it has to be firm, very well leveled, smooth and dry. Wood is like a sponge – it takes and it gives dampness all the time which leads to swelling. For this reason before fitting it, the parquet needs time to adapt itself (it has to equal its dampness to that of the premise in which it will be fitted), and this process may take a week or two. Dampness should be no more than 50-60% in the premise during the fitting and should stay within these borders throughout the time of the exploitation in order to avoid the eventual deformation. Another advantage of the parquet is that depending on the way of its arranging different figural composition can be achieved. At present, the most popular way of arranging the parquet - the so called “fish bone” is replaced by placing big, rectilinearly arranged tiles with various shades of color and different patterns thus making the whole composition more attractive and unique. There are several techniques for fitting the parquet, each of them has advantages and disadvantages. The “sticking technique” is recommended because the parquet becomes steadier if it is incidentally waterеd but it can not be removed or pre-arranged later on. By using the “forging technique” pre-arrangement and the removal of the parquet is possible but the gaps are not tight so well, while by using the “floating technique” the elements are fastened to one another without sticking to the base. This last technique is mainly used when fitting laminated parquet and it is not recommended for massive parquet.

Three-layered parquet

Massive wood flooring

Another kind of massive parquet is the three-layered parquet that consists of layers of wood fastened to one another as every following layer is placed at 90º towards the previous one. Thus a peculiar three-ply is formed with a massive top layer about 6-8 mm thick. This three-layered parquet has one big advantage that it is being offered as prepared consolidated elements, which are polished so fitting becomes easier and more quickly. However if the base is not perfectly smooth then a difference in the height of the parquet elements may appear at some places which is hardly to be seen unless you step on. The quality of this parquet depends on the thickness of the top layer – if it is thicker it could be scraped much more times. Unfortunately the price of the three-layered parquet is not too low compared to the price of the massive parquet.

Celenio wood tiles

Celenio wood tilesCelenio wood tiles offer the look or leather, stone or slate with the cool feel of wood flooring instead of the cold feel of tile. This is new and relatively unpopular system. It is made in the form of flexible, stable wood tiles cut broad wise instead of longitudinal as it is usually done with the ordinary parquet.
In a complex, patented process, this innovative wood-based product is moulded under high pressure into three-dimensional wood tiles It is fast and easy to install using an innovative peel and stick technology.

Celenio wood tiles are suitable for most rooms in your house, including the kitchen, dining room or living room, but are not suitable for wet areas like laundry or bathrooms. It won’t crack or break like stone.
This system allows arrangement of the tiles in various designs with appearance of wooden, stone or terracotta flooring or such that look like leather but still it keeps the pleasure, the comfort and the atmosphere that only natural wood can create. Fitting using “Celenio” system requires temperatures between 18-22º C and dampness between 40-60% in the premise and it is essential that they stay the same afterwards. Cleaning is always by wet cloth.

Laminated flooring

Laminated woodlooringThe cheapest and the most popular imitation of the massive parquet is the well known laminated parquet. It has several layers: the first one is very strong; the second one is decorative laminate - impregnated with melamine paper with wooden appearance, followed by water resistant layer made of firmly extruded wood fibres (MDF or HDF) and balancing layer that serves for the regulation of the internal tensions and removes the risk of hogging.
It is a disadvantage that laminated parquet can not be repaired if damaged but it is more stable to dampness and if watered incidentally it swells harder.
The laminated parquet can not create the same atmosphere and feeling especially by touch that only natural wood can bring but looked at from a distance it imitates and looks like real wood very much. Undoubtedly the most important advantage of the laminated parquet is its price and also the great variety in colors and patterns of laminates that are offered on the market.

Possible problems when building a pool

What problems should be expected when building a swimming poolIn-ground swimming pools are the most permanent constructions, so it’s important to be sure about your choice of builder for your swimming pool.


Choose a professional - Some builders offer construction services only, and you will need to hire extra a pool company to deliver and install the pool equipment separately. Here we will try to report about the problems that could arise when building a swimming pool in Bulgaria.

Just imagine your pool is ready and it is leaking or the filtration system is not working properly. The builder is blaming the pool company and the pool company is blaming the builder. If the pool company don’t work side by side with the builder this is most likely to happen. Our advice is to hire one company to build your pool which will then stand for its job and gives you the full guarantee and post guarantee repair and maintenance service.


Swimming pools in Bulgaria?
About 10 years ago there were just some swimming pools in the summer resorts and other places near the sea in Bulgaria. From Bourgas down to the Turkish border there were several communal swimming pools and private ones were hardly to be found.


At that time only a few companies were involved in the construction of swimming pools and they covered the whole country. Generally, these companies just delivered and installed the machinery and the equipment and did some of the finishing works. All major construction works were and are still carried out by companies that have no experience that is required for this type of building.


As a result of this a large amount of the swimming pools in Sunny Beach resort and along the Black Sea coast have problems keeping the water into the pool because of leaks that appeared due to of poor quality construction works and they have to be filled up with water on daily bases in order to avoid leaving the pool empty in the heat of the summer.


Everything has its price, especially with the swimming pools. If you save some money on materials and labour (skilled professionals) you will have problems in the future and instead of enjoying your new swimming pool it may bring you some negative emotions.


We believe this post will be useful to those of you who have decided to have a private swimming pool built and our professional advices will help you in taking the right decision.


Proper excavating and formworkExcavation work for swimming pool in Bulgaria
It is very important when designing the swimming pool to plan enough space in order to provide an access for the building machinery. Quite often because of such lack of space and savings, when doing the excavation works, the walls of the hole for the pool are dug vertical in order that they serve as an outside formwork. Then the wall is reinforced with steel, the inside formwork is put, and the concrete is poured in the wall.

From professional point of view this is impermissible. In this case when the concrete is poured in the wall, earth will fall in the gap between the bottom and the walls and it can not be treated against leaks. Besides, it becomes impossible to vibrate the concrete to the required extent and the wall will not be waterproof. The following hydro insulation (waterproofing) of walls and bottom will not be enough to stop water leaking; it cannot be effective if water penetrates the concrete. If the concrete shell is poured in thus miserable way then the only option will be high quality waterproofing, professionally applied. which is very expensive and this procedure will lead to additional expenses.


Waterproofing construction jointsWaterproofing construction joints
Waterstops are used to waterproof construction joints, between separately cast slabs. They are generally PVC or vinyl. Waterstops are embedded in concrete joints to create a fluid-tight diaphragm. On most occasions this waterstop tape is either saved or it is not properly installed. The consequences can be very unpleasant – water leaks and delay of the project.


PVC Tubes and fittingsPVC Tubes and Fittings into the pool walls
Delivery and fitting of the pool shell equipment (pipes, tubes, inlets, drains, skimmers, lights, etc.)that is placed at the bottom and into the walls is also very important for the quality of the construction works. The installation has to be fitted according to the technical instructions. If installed correctly there will be no risk to ruin the reinforcement and to damage the system. Otherwise the pipe installation can be partially cut off which will lead to its blockage and impossibility to perform its functions. It is recommended that the pipe installation is fitted inside the concrete and not outside it for safety reasons because the fill up with earth that will be made around pool could damage the pipes.

Checking for leaks
When the concrete shell of the pool is ready it has to be filled with water, after 28 days of pouring of the concrete (see how to work with concrete), in order to be tested. There should not be any leaks of water. Anyway if such leaks appear in some places they have to be treated according to technological requirements with the needed materials. After the leaks are removed then the next step will be applying the waterproofing, minimum two coats but three is better, and glass-ceramic tiling installed.


Possible problems that may emerge at this stage are related to the quality of their application and also to the unsuitable weather conditions - if it is very cold or very hot, or wet when the glass ceramic tiles are fitted, then they could fall down by next winter.


The Investors have to be aware that climatic conditions in Bulgaria are not very favorable for pool’s maintenance. In some areas, including the areas along the Black Sea coast winter can be very severe. Within winter period from December till March, freezing and cold may last few weeks. If the tiles are not professionally tiled and the pool itself is “unprepared” for winter season then some unpleasant surprise are quite possible such as an unexpected need of repair and additional expenses.


We have tried to point out some of the problems that may emerge when putting the swimming pool in operation.


We would recommend that you make efforts in order to find a reputable company that has the required experience in pools construction. Also it is very important when choosing a company to find out if the company will be responsible for maintenance of the pool within the warranty term and after this term expires.


Our company guarantee you that upon enquiry we will make you an offer at competitive prices in accordance with your requirements. If our offer is acceptable for you we will build your swimming pool in shortest terms and also we can take care of your pool’s maintenance on request.

How to insulate house for winter - Guide on External Walls Insulation with EPS panels

Insulation is cleverInsulation is very clever. Not only does it make your home warmer in winter, it also helps keep it cooler in summer. This is a little bit like a flask which keeps drinks hot or cold by providing an insulating layer between the drink and the outside air.

Air is a poor conductor of heat, so the tiny pockets of air trapped in insulation minimise the amount of heat which can pass between the inside and outside of your house.

Heat insulation doesn’t only work in winter: while the walls are kept warm during the cold season, in summer the heat insulation works like climate control. The outside walls are well insulated, do not get too hot, and the rooms stay comfortably cool. Without extra equipment, without extra electricity and without extra energy consumption.

Top insulation measures:

Loft insulation

Loft InsulationAround 25 percent of heating energy disappears through the roof in an un-insulated house, making insulating your loft one of the most cost-effective ways to save energy in the home.
Loft insulation acts as a blanket, trapping rising heat in the house. Without loft insulation you could be losing as much as 15% of your heat through your roof, so this type of insulation is a simple and effective way to reduce your heating bills. You can even do it yourself with a bit of planning.
Glasswool is the most cost-effective and widely used loft insulation. Made with a high proportion of recycled glass it requires no maintenance and will last a lifetime

Windows

If you have poorly sealed windows and doors you may be losing 15-20% of heat through the gaps. A replacement with new PVC windows with double glazing is probably the better solution than draught proofing (which is cheap but ineffective)
Double glazing traps air between two panes of glass to create a barrier to heat loss by approximately half.

External Wall Insulation

External insulationExternal wall insulation is a straightforward job and it’s an excellent way to save money on your heating bills.
Expanded Polystyrene (EPS)
Expanded polystyrene (EPS) is manufactured from small spherical beads of styrene which are pre-expanded with Pentane. The beads then expand to over 40 times their original size when heated by steam. The expanded beads stick together under heat and pressure inside a mould and the finished product consists of approximately 98% fresh air. Expanded polystyrene is also known as ‘bead board’.
Characteristics

  • White/grey colour
  • Lightweight
  • Suitable for temperatures up to 75°C
  • Mainly available in 2.4m x 1.2m sheets

Main uses

  • General/domestic-floor thermal insulation
  • Wall insulation
  • Packaging and fabrication

Heat loss - thermographic image

Thermographic image of a houseThermographic images clearly show that weakness in the construction, such as thermal bridges, which transfer heat to the outside, cause extreme heat losses.

This doesn’t have to be the case:
this can be prevented by a thorough, balanced thermal renovation of your house. This is expressed not only in the saving on heating costs, but also by a more pleasant room and living climate.

Red = extremely strong heat loss
Yellow = strong heat loss

Insulation and Facade in one with:
Baumit EPS Heat Insulating Composite System

- Groove structure: app. 2,7 km/m2 or 3,9 km/m2 for particle size resp. 2mm or 3mm


How to install the panels

Base surface: The base surface must be free of loose and/or crumbing parts. The base surface must be dry, clean and free of salt blooms
and expansion joints. Cracks in the base surface should not affect the function of the WDVS. Subsequent moisture penetration of the base
surface must not be allowed to occur. There must be no identifiable rising damp.

Applying Base Profile approx. 30 cm above ground1. The Baumit BaseProfile is secured approx. 30 cm above ground level using Baumit BaseProfile plugs. Where the wall is uneven, the profile is padded out with spacers. The joints are connected using Baumit BaseProfileConnectors. In addition, the profile can also be fixed to the wall using Baumit EdgeFix.


applying the adhesive over the panel2. The adhesive is applied using the edge-dab method. The application should be done in such a way (approx. 1-2 cm thick adhesive layer), that the contact surface with the wall is at least 40%. A 5 cm wide strip of adhesive is applied around the edge of the panel, and three dabs, about the size of a side plate, a placed in the middle.


Inserting Plugs on insulating panels3. Before the plugs are inserted and after the adhesive has hardened (after 1 day), the panel joints are sanded down until they are level and smooth.
T-plugging: Example with 6 plugs/m2 of surface.


Application of Adhesive Filler embedding Fiberglass Mesh4. Application of Baumit Adhesive-Filler using a rust-free toothed spatula (10 mm). The Baumit FibreglassMesh is embedded “wet on wet”. At least 10 cm overlap of each drop. Curing time before application of primer: at least 7 days.


Run sheets of Fibreglass Mesh at least 20cm around corners4.1 Run the sheets of FibreglassMesh at least 20 cm around the edge on one side. The following sheets overlap by at least 10 cm. Alternatively, we recommend forming the edges with Baumit EdgeProtector with fabric.


Reinforce corners of windows and doors with mesh4.2 In the corners of windows and doors, diagonal reinforcement (at least 20 x 30 cm) is embedded before the surface reinforcement.


Reinforcement strips of mesh are embedded in the internal corners of windows and doors4.3 Additional reinforcement strips are embedded in the internal corners of windows and doors.


Primer is applied across the surface with a roller5. After the Adhesive-Filler is cured (7 days after application), Baumit UniversalPrimer is applied evenly across the surface with a roller. Curing time: at least 24 hours.


Coloured Plaster is applied using trowel and then plastic board6. Baumit GranoporPlaster is applied using a rust-free steel trowel and rubbed in using a plastic float. The plaster is available in 200 colours.


We alwasy recommend the materials of Baumit to clients asking for a quote for external house insutaion. Baumit is a reputable German company producing building materials of high quality and long durability. The high quality adhesives and plasters when installed properly guarantee for the long life of the façade of your house with colour that would not become fade in three year of application.
Of course there are cheaper EPS insulation systems available from other producers. These are not of the same German quality but are still good. In some cases the façade will have to be repainted after several years.
