Foundation

Is it worth to use the proposed combination of a foundation bench and a slab foundation - a coffered foundation?

We strongly recommend this solution. What distinguishes this type of foundation is primarily the durability and reliability of the structure. In addition, you can’t forget that it saves the customer time and money. It is a complex of works – foundation, flooring, underfloor heating, insulated and horizontal, waterproofing, which we do simultaneously and cheaply!

Walls

Is it recommended to build a house using a material such as (lime-sand block)?

We built and still build houses from Silk. With the use of this material or aerated concrete and Porothermu, excellent buildings are created. Unfortunately, with these construction techniques it is necessary to make a reinforced concrete lintel, so we propose two types of wall structures: concrete and skeleton. This allows for the acceleration of construction work completed with the building shell.

But concrete is often associated with the cold?

Yes, that’s right. Concrete is very cool, but it is basically the specificity of all stone building materials. For example, the warmest stone material used for building walls is M400 aerated concrete. Its specific thermal conductivity is 0,2-0,3 W/mK at an external humidity of 60-80 % and an ambient temperature of 5 °C/-5 °C, which corresponds to the autumn/spring period. According to the new requirements from 01. 01. 2021 for insulation of external walls, the thickness of such a wall should be 1m The price of one m3 of aerated concrete is in the price range of concrete, so why buy a material that does not meet modern requirements. As far as Porotherm 44 T Dryfix is concerned, its price per 1 m3 is PLN 400. It is a ‘warm’ material, but the house sections and lintels are made of concrete, so they should be insulated just as much as the whole wall.

Although Porotherem, aerated concrete and Silka are partial insulation, no one leaves the wall at this stage of construction.

Exactly. All in all, what is the point of a material that is inferior to concrete in terms of strength and mechanical load acceptance. The concrete is at least 5-10 times stronger than aerated concrete, 1. 5-2 times stronger than silicate block, while Porotherm is not worth mentioning here because it is a very demanding and time-consuming material. In such a case, we propose to use reinforced concrete, and the rest of the funds planned for the construction will be used for warming up.

Why are we building skeletal houses and not based on SIP panels?

First of all, houses built with the use of SIP technology are inferior to classical frame houses in relation to the time needed to create a structure. SIP panels are usually manufactured for 2 to 4 months. The construction of the frame house starts within a week of receiving the building permit. Secondly, laying the house’s engineering networks requires extra time to build a structure for plasterboard, and in the case of backbone houses this is done with the wall. Thirdly, it is not easy for both the manufacturer and the buyer to control the quality of materials. Houses made of SIP panels consist of polystyrene and OSB. The latter material, while retaining the properties of wood, can work and change form under the influence of moisture. In addition, SIP panels emit harmful substances, such as formaldehyde, styrene, phenol and ammonia.

INTERNAL WORK

Why did we resign from installing radiators?

Modern house insulation standards make it possible to abandon the use of the radiator because underfloor heating produces sufficient power to cover heat losses, which is about 50 – 60 Wh/m2. This is sufficient to heat and maintain room temperature. However, it should be remembered that in rooms with large windows, such as terrace windows, installation of heaters is necessary. In the bathroom, on the other hand, you can only install an electronic bathroom heater, which in combination with the underfloor heating system will provide warmth in the autumn and spring.

Do we use heat recuperators?

We have recently given up the use of heat recuperators because they make noise during operation, which can cause discomfort during the sleep of the household members. Another possible solution is an easy to operate ground heat exchanger. Thanks to the low price of this equipment, it is worth considering its installation, as it helps to save money not only for heating, but also for cooling in the summer.

Why do we install light switches 90 cm from the floor?

Installation at a height of 1. 5 m from the floor is now a thing of the past. In the past, in order not to accidentally hook the switch, it was mounted at eye level. Now it is not necessary or even less desirable. It’s more convenient for us to lean our hand against the wall, not to raise it. This is extremely important for children aged 4-10 years because it will allow them to switch on the light in the room by themselves.

Why is automatic fuses recommended for each circuit?

The safety of our loved ones is paramount. There are children in every family and regardless of age, they are very curious about the world. Sometimes, because of our responsibilities, we cannot afford to stay and play with children all the time. Therefore, for the sake of our children’s safety, not only in the children’s room, but in every room, only the sockets can be unplugged and the lights left on. This solution is also applicable in situations where an emergency power cut has occurred. We can easily find the cause, as separate light and socket fuses will help us to identify the source of the problem, allowing others to continue using electricity. This is very convenient because we don’t have to wait that long for an electrician to help us.

Do we recommend installing a system to protect the building against flooding?

Yeah, that’s very appropriate. 10 years ago, we did a thorough renovation of the apartment. Unfortunately, there was a flooding later, which was caused by a faulty tap. Fortunately, the apartment owner’s insurance covered half of the material losses, but it was possible to prevent this type of failure by installing an anti-freeze system. Now we discuss the installation options for this type of protection with every customer and put them into the project from the beginning!

What types of interior walls do we prefer?

In our opinion, walls with increased sound insulation are the best solution. This can only be achieved with basalt wool, i. e. gypsum cardboard panels combined with OSB panels.

Why is the installation of stretch ceilings a priority for us?

We make any kind of ceiling, for example made of gypsum boards, a suspended tile ceiling, a suspended panel ceiling or simply finishing the ceilings with plaster. However, we put the greatest emphasis on modern stretch ceilings. Nowadays, this is one of the best solutions. This type of ceiling is environmentally friendly, quick to install, because we need only one day to complete the work, gives us a wide range of colors and most importantly – it allows to achieve a perfectly flat surface. Moreover, it is also important that if we decide to use this type of ceiling in a finished, furnished room, we can be sure of order and tidiness after the work is completed.
