The surface temperature as one of the most watched parametres of the opening panes and light enveopes not only in the Czech Republic is being assessed in a view of risk of water vapour condensation, or more precisely in a view of their health and a hygyenic flaws and ecologically sound environment where inbuilt. The mening is determination if the structure is suitable for the marginal conditions or whether is necessary to choose another structure.

In the article, I would like to draw attention to the issue with an outside window lintel on existing double glazed windows. The lintel is mounted below the other lintel and can therefore when replacing windows in modern window to form a problem. The article presents possible solutions window lintel. The most appropriate way is a solution that includes the total renovation of the building envelope with the replacement of windows.

The exact determination of emissivity and the following determination of surface temperature of glossy materials can be carried out e. g. after applying a material with a known value of emissivity on the surface (e. g. self-adhesive foil or spray tint). The contribution deals with other possibility of determination of surface temperature and the influence of emissivity of glossy materials using a metal shield that reduces the negative influence of the reflected radiation during the termographical measurement.

Prague building regulations currently represent debated and controversial topic among both professionals and the public. This is a new concept of law to which they are greatly implemented basic knowledge of urban theory and practice. The article summarizes the basic principles of the new regulation in the field of territorial requirements.

Hidden defects of buildings, which may become evident only in winter, are one of the biggest problems of any real property purchase. The article gives some advice how to detect them in advance so that the buyer may be prevented from submitting time consuming, expensive and often ineffective claims in face of the previous owner.

This section is a continuation of the four-part article. "Defects and breakdowns construction wall opening" which states the defects in the timber windows which has been a problems for ten years. After further analysis by a team of experts, it was determined that the windows do not have an airtight seal. The problem area is the mounting of the windows which includes the glazing and silicone process.

The article describes the most frequent defects and breakdowns of using timber windows the author experienced for 10 years during his praxis. These problems are divided into the defects of construction arising from production. The defects and breakdowns during the assembly and the defects and breakdowns timber windows have during operation and construction.

Years of speculation about the correct windows installation finally ends. On May 1^st the new standard ČSN 74 6077 Windows and external pedestrian doorsets - Requirements for installation came into force. It is the very first implementing standard for this branch of construction. The standard is based on the technical standard information TNI 74 6077 and replaces it.

The article deals with the determination of effects of heat radiation on the quality of the indoor environment in winter season, while insulating by double and triple glasses. Effect of radiation through the fillings of the panels and building structures has been evaluated on the basis of knowledge of the mean radiation temperature and operative temperature in the given indoor environment. Isotherms of mean radiation and operative temperatures for different cases of application of insulated glasses having different coefficients of thermal transfer have been presented.

The 8th part of the series about doors and windows is focused on the process of acceptance of the work including the assessment of defects and unfinished parts, and their removal. It recommends length of warranty periods and claim application.

New Civil Code enacts special type of solidary obligation to remedy the defects of building constructed under contract for works. All subcontractors (suppliers) of constructor, investor`s technical supervisors or construction project designer are solidary responsible together with the constructor in case the defect can be attributed to the performance they provided. However, these parties need not to be the parties to the contract for works itself (and usually are not) as their obligation arises by law.

The remedies that the investor can claim on these co-debtors, however, are limited to right to demand the repair of the defect. Investor may demand remedy on any of the co-debtors and all the co-debtors are obliged to perform the remedy in full.

The investor has to give notice to the debtor within a reasonable time. The notice can be sent to any of the co-debtors but we advise all investors to give notice always to the constructor first or together with the other co-debtors.

If you selected a high-quality windows and doors for your construction, the overall success depends only on the quality of installation. The most important is quality of the gap between the window frame and jamb. The basic three parts of this gap are inner and outer seal and thermal insulation.

Only properly designed windows or doors with matching parameters and their proper building in the construction are a prerequisite for long-term trouble-free operation of them. Building-in of the windows is topic of the sixth part of the series about windows and doors.

The article deals with a new product in the Czech market that is quickly getting to awareness of potential clients and gaining a significant place in the local real-estate market. Until recently, the inspection of immovable properties was an unknown concept. Nevertheless, in recent two years such assistance service is being more and more popular. Pertinent specialised inspection companies assist the real property buyer in eliminating potential risks that are related to selection and purchase of a given building. A competent certified inspector checks up to about 200 items of the building and compiles an expert report to help the client to correctly decide whether he should buy the given building or not. The inspector will acquaint the client with a real purchase price, precisely describe all the defects and how to correct them, and finally, he will hand over to the client a complete budget to cover the cost of necessary repairs.
In 2013 the inspection of real properties comes to one of the fastest growing segments of Czech economy. The people intending to buy any real property are more cautious and, now at the time of an economic uncertainty, they begin using the above relatively new assistance service in a large extent.

The fourth part of the series about windows and door is focused on Window hardware. Window hardware performs two functions: It allows opening of windows and doors and also, if closed, ensures meeting most of the required properties.

The third part of the series about windows and doors is focused on functional gap of the window. It must allow smooth opening windows while ensuring the required thermal and acoustic characteristics, resistance to infiltration of rain, sealing against wind and other properties.

The second part of the series about windows and doors is focused on wooden windows, especially on specific natural material of the window frame, characteristic details of the structure, and the way of its instalation.

This paper is the first part of the series about windows and doors on TZB-info. The series will be focused on all elements of windows and doors, their design and construction. We will highlight in detail the most important aspect for choosing new windows or doors. This first part is focused on windows and doors with plastic frame.
