We take your questions seriously and show you how you can obtain ideal results.
The penetration of humid room air into the structure is prevented by this layer, thus preventing condensation of this humidity at points where surface temperatures are below the dew point. An airtight seal is fitted to prevent uncontrolled heat losses and drafts via the connection joint.
Thermal and acoustic protection are guaranteed by this layer. The functional area must remain dry and must not be subject to condensation from the room side nor driving rain from the outside. 5 % humidity can reduce insulation by up to 50 %. Our product solutions do not permit this at all.
Level 3 must be designed to resist driving rain, as a wind and rain barrier. Driving rain values of at least 600 Pa are usually required; these are achieved or even clearly exceeded using sealing solutions from the ISO³ WINDOW SEALING SYSTEM.
Connect joints are the weak point of the building envelope, so, we must design functional and reliable sealing joints at the planning stage.

2002 / 91/ ECDirective - Energy Performance of Buildings
DIN 4108/7 – German energy requirements, in accordance with national legislation, point out various installation possibilities, and involve the flow of air tightness and moisture, as well as "internal air tightness is better than the outside air tightness" criteria. Accordingly, the internal joints sealing should prevent indoor moisture penetrate and enter the joints, avoid condensation. However, it must ensure that all residual moisture in the joints can flow out through the masonry to the outside.
When we consider the renovation of buildings and improve its performance, we can not ignore the sealing building joints which is the main factor. Because a lot of hot air is often lost from here, it’s reflected by the fact of the high heating costs.
In addition to reducing energy losses, the long-term ability of sealing joints is an important safeguard to improve interior comfort, because new construction and renovation of houses in the cold air will not only cause discomfort, but can lead to condensation and mildew problems.
Innovative topics of related building energy have malleable properties, which is why newly built and renovated houses need to have clear rules and guidelines. In order to ensure the best overall results, only from the energy point of view to combine all the architectural elements effectively.
People accustomed to using modern sealing materials in new construction and renovation of buildings, there are many products available to choose. But what kind of solutions is the best? You can consult us.
In Germany and many other European countries have adopted similar legislation, Energy-saving requirement prescribed the main laws of transformation of the buildings, which is also the main regulation of building sealing joints.
In addition to make a clear definition of the U-value for windows, exterior doors, roofs and walls and other components, the Act also explicitly adjust the update of the Buildings Ordinance.
Accordingly, the construction of the building must ensure the joint permanently sealing. When new or replacement of existing buildings structural components, this specification is equally effective.
Air tightness is the most important requirement, which means that on the one hand is reducing heat loss, and the other hand is the controlled disposal of moisture in the air.
a-value expresses the tightness. This value is not more than 0.1. In general, this value cannot permanently achieve by using thermal insulation foam adhesive to fill the joints between the windows and activities of structure.
Permanently elastic sealing material buffers movement structure in the case it does not damaged. so ensure to keep weather resistance and airtightness for a long time.
Belower-Door testing
air tightness of the building is very important to energy-saving.Belower-Door tesing can be used as a standard test to detect the airtightness of building envelope.
a - value
is breathable characteristic value。This value represents the maximum amount of air per hour through one meter length of the joint.The smaller the value, the less energy loss, and the less cost.
sd - value
represents the ability of a material to prevent moisture penetration. The larger the value, the more it can prevent moisture penetration.
