HISTORIC BUILDINGS AND ARCHITECTURAL MONUMENTS

Problems and possible solutions

In order to protect historic buildings, significant architectural monuments and protecting copyrights of their expression, it is required to maintain the character of the facade and existing architectural design.

External insulation by standard thermal insulation systems of thermal insulation boards is unacceptable in case of the above constructions due to the plasticity of their facade and the heritage conservation requirements. Internal insulation is possible to some extent but limited by many requirements. Even the choice of a partial internal insulation is affected by problems with non-identifiable material base with a construction, plastic ornaments and only limited increase in thermal resistance due to the danger of frost penetrating through walls in greater depth up to the disintegration and plaster falling off and an increase in humidity in the masonry due to the lack of a temperature gradient.

WATER CONDENSATION AND MOULD

Problems and possible solutions

As a result of thermal bridges, inadequate parameters of internal environment, especially the high relative humidity of the internal air, unsolved construction humidity of defective structures and sharp changes in the ambient temperature, water vapour condensates in the structure and on its surface. Wet areas with plenty of nutrients and a suitable environment for the growth of organic substances harmful to health and hygiene are formed on the surface of walls. Even the surface changes, invisible to the naked eye have serious consequences. An ideal microclimate especially for the production of highly dangerous mould is created. More information...

INDUSTRIAL EQUIPMENT

Problems and possible solutions

According to the temperature of a flowing medium, there is often water condensation on cold water piping, heat loss on hot water piping and industrial installations. Conventional insulation is not always a good solution. There is considerable heat loss not only in the joints but also the individual fittings. Wrapping the piping is laborious and time-consuming; to install and repair the insulation, it is usually necessary to interrupt the operation and expose the surfaces of considerable extent. The condensation between the pipes and insulation leads to wetting of the insulation and a degradation of its thermal insulation properties. More information...

THERMAL COMFORT IN FLATS AND COMMERCIAL BUILDINGS

HOUSE FACADES BEFORE RECONSTRUCTION OR REPAIR

Problems and possible solutions

Historical buildings from the 19th and 20th century and buildings of reinforced concrete panels, burnt ceramic material (full burnt or perforated bricks) and foam concrete do not meet current requirements regarding the thermal insulation properties. Most exposed surfaces of perimeter walls, panel joints and walls of both brick and autoclaved aerated concrete buildings are constantly exposed to damaging influences – of humidity, aggressive action of external environment, thermal and ultraviolet radiation. Cracks, leaks and internal mould infestation are common defects in these buildings. More information...

INTERIORS BEFORE RECONSTRUCTION OR REPAIR

Problems and possible solutions

Current historic buildings often do not comply with the requirements regarding thermal insulation properties. Some structures cannot be (effectively) insulated from outside the structure. Building walls are constantly exposed to damaging influences – humidity, aggressive effects of internal and external environment. Frost penetration through walls, surface condensation and internal mould infestation are common defects of buildings, including their basements or underground parts. More information...
