What kind of technology are you using for building the houses?

ZIP HOME building system is based on the SIPs technology. This technology uses load-bearing, isolated sandwich panel, which consist of the load-bearing envelope and of isolated core.

Isolation made from EPS (expanded polystyrene) is laminated between two layers of OSB (oriented strand board). This progressive building technology originated in the USA and it is used since 1930.

What is OSB?

 Oriented strand board, also known as OSB (UK & U.S.) and Sterling board (UK & Ireland), is an engineered wood product formed by layering strands (flakes) of wood in specific orientations. In appearance, it may have a rough and variegated surface with the individual strips (around 2.5 by 15 cm each) lying unevenly across each other.

Can you deliver the house only or also the foundation slab or the cellar? 

We also offer a building of foundation slab or cellar. The price of the foundation is different and depends on the size of the house, technology used to made basement, or cellar, type of building material used, material availability, foundation conditions, etc.

Price of the house foundation depends on several factors and circumstances on the building site, such as: 

Access to the building plot, the complexity of the transfer of materials and technology in the establishment of earthwork, the distance of the landfill to save landfill excavation (excavated soil), price for the storage of excavations, transport and time limitation on the territory.

Elevation of the building plot in the area of construction, stabilisation of the excavation, high of the ground water, soil quality.

Pumping of the water from the excavation pit, drainages, embankments, sheeting. 

Basic methods of making basement plate, base-belts, earth piles, ...

Reinforcing of the basement depends on the soil quality and conditions, the geology, or other methods used to stabilize the substrate.

Based on the evaluation of the radon measurements it is possible to make anti-radon measures, etc.

Where are you building and delivering your houses? 

We are building and delivering the houses across all EU

What is the thermal resistance of the construction of the wall?

Basic design of non-insulated wall structure without the extended facade thermal insulation is as follows: 

-ZIP4_170 R is3,736 m2K/W

-ZIP4_210 R is 4,736 m2K/W

-ZIP4_270 R is 6,236 m2K/W

The thermal resistance of the wall of the house with additional contact facade insulation system using the EPS_80 quality insulation boards from outside and the interior fitted with plasterboard, the thermal resistance of the wall is as follows:

-ZIP4_170 + StiroEPS80 hrúbky 80mmR - 5,882 m2K/W

-ZIP4_170 + StiroEPS80 hrúbky 100mmR - 6,667 m2K/W

-ZIP4_210 + StiroEPS80 hrúbky 80mmR - 7,143 m2K/W

-ZIP4_210 + StiroEPS80 hrúbky 100mmR - 7,692 m2K/W

-ZIP4_270 + StiroEPS80 hrúbky 80mmR - 8,333 m2K/W

-ZIP4_270 + StiroEPS80 hrúbky 100mmR - 9,091 m2K/W

These are just some examples of the structure for the exterior walls. 

How is the house ventilated?

For the construction of energy efficient or passive houses in the standard of ZIPHOME it is necessary to use appropriate ventilation system with heat recovery units.

This option is also the most comfortable with easy way of control. There are many different systems for ventilation - centralized and decentralized.

Specific solutions are given in detail in individual projects.

For the lower energy standards of the houses, we offer the easiest systems with forced ventilation with windows using micro-ventilation and humidity sensor controlled fan. This option is not suitable for energy efficient or for passive houses.

Can I provide some work on the house alone to save the cost? 

Of course, yes. Scope of the supply depends solely on your decision. You can decide and choose one of the finishing degrees of your house:

Do you provide a sample projects of the family houses?

Yes, we do. Some projects are already listed on our website. Other new project will appear soon.

What is the process of obtaining a building permit and final inspection of ZIPHOME houses ?

Method of obtaining a building permit for ZIPHOME houses is the same as for other buildings from other construction systems. The process of obtaining building permits, construction and final inspection is also one of the services that we offer to our customers.

Are the ZIPHOME houses earthquake resistant?

Yes, they are. On our web site you will find some references to such a houses built with SIPs technology. We sell these houses under our brand - ZIP HOME.

What does the ZIP HOME wall consist of ?

ZIP panels are constructed from the load-bearing OSB plates and from EPS insulation core laminated between the OSB plates. 

We are using the OSB4 boards - the structural plates recommended for high mechanical loads, suitable also for the environments with increased humidity. When the project implementation and operational conditions are kept, there will be no degradation of the material used.

OSB - Oriented Strand Board are pressed flat plate made from oriented large-scale particles composed of three layers and bound with synthetic resin binder. These plates were developed in the North America in the fifties as a full substitute for more expensive and at that time scarce building materials - plywood, used in the U.S. and Canada for all kind of wooden buildings. In these countries, like also in the Scandinavian countries, the wooden construction of the houses and other buildings has the great tradition and popularity.

On the European market belongs to OSB only that flake board, which meets the standard of EN 300.

EPS (Polystyrene) is a thermal insulation material. This plastic material is not subject of material degradation. Polystyrene is one of the most widely used plastics, the scale being several billion kilograms per year.

How much does the installation of shell construction of ZIP HOME cost ?

Price of the installation depends on various factors. It is affected by the size of the house, by the site conditions, local circumstances of the building site, local legislation, accessibility of the building site by building mechanism, the availability of the energy on site, etc.

Approximate cost of the shell construction for installation in standard version is in the range 25% -38% off the total price. 

Circumstances which affect the price: 

Access to the building site, the complexity of the transfer of materials and transfer of technology, distance to the landfill, size of land

Elevation of the building land in the area of construction, distance to the transport roads

Restrictions on working time (Saturdays, Sundays, Holidays, …) 

Protection of the site - the site dependence

What kind of material is used for the facades ? 

As a final finish of the external walls - the full contact insulation system with silicate plaster scratch is normally used. For the final outline - any type of hinged facades of wood, plastics, composites, and stone is possible.

More information can be given during consultation with our expert.

What kind of warranty I would get for the house ?

For the supply of the shell construction we provide a standard guarantee of 36 months. Extension of the guarantee period may be offered for additional charge. 

The guarantee conditions are described in the contract.

What kind of the material is used for interior walls ?

The interior load-bearing walls are made from the ZIP panels. They are lined with plasterboards. Other (non-load-bearing) internal walls are created as a dry construction. The most commonly they are made as plasterboard drywalls.

How it is with the house soundproof ?Do you hear a conversation from one room to the another one ? 

The construction of ZIP HOME meets the standard prescribed by the boundary conditions for permissible noise levels in the buildings.

If the house is built in standard of ZIPHOME, it meets all the requirements for the building acoustics: airborne sound insulation structure as well as footfall sound insulation.

What are the requirements for a passive house ?

There are only a few requirements in the principle to be met:

The plot with a suitable orientation (to find a suitable plot)

The project documentation worked out with regard to the principles of Passive House

Compliance of the construction with the project documentation

What is used on the roof of the house ?

The composition of the roof is specified in the project.

As the roofing is in principle possible to use any kind of covering available like the foils, bitumen, clay tiles, concrete tiles, various fittings, metal roofing or other material.

Based on your idea we will recommend you the suitable composition of the roof on your ZIPHOME. 

What is the difference between conventional construction and ZIPHOME construction ?

The ZIP HOME building system brings several advantages:

Building elements (ZIP panels) are load-bearing and they contain thermal insulation.

In comparison with the building materials (such as brick) the ZIP HOME building system offers the advantage of “magnification” of the living area thanks to thinner walls.

The thermal resistance of the panel with a thickness of 170 mm used for walls is R = 3.736 m2 K/ W.

The panels are flat building blocks, which speed of installation is unmatched by traditional methods of construction.

The entire assembly of the building construction is without wet processes. The elements allow exposing them for the load immediately.

Usage of a water for a house ?

Water supply for a house can be addressed from your own well or from a connection to the local water supply network. It depends on local conditions, location and availability of public networks. 

What kind of material is used between the floors ?

You can find all types of structure samples on our web site.
