REQUIREMENTS FOR OFFICE SPACE
The PN-B-02151-3: 2015-10 norm, in force since 2018 in Poland, significantly tightened the requirements for acoustic insulation and introduced the obligation to comply with them.
FREQUENTLY ASKED QUESTIONS
Mainly due to construction differences – the walls are fixed elements, they are characterized by a higher weight, they are sealed during assembly and not dismantled during their exploitation time. On the other hand, doors are usually lighter in structure due to the need to ensure mechanical durability and ease of opening. In addition, as a movable element, they are characterized by lower tightness, due to the need to adapt to opening and closing (restrictions on sealing methods, etc.).
In the case of mounting to suspended ceilings, it is recommended to use lintels or other fixing structures, both to maintain the stability of the wall and to close the sound path outside the wall. In the case of fire protection systems, one should also remember to ensure fire tightness of the entire partition, also in the invisible part.
Laboratory type testing is performed on a representative sample and the result covers the entire structure with joints. Research experience shows that correctly made joints do not noticeably affect the measurement result, and the width of the forms is best adjusted to the transport and assembly possibilities and to the required aesthetic effect.
The type of wall should be selected on the basis of acoustic properties, depending on the requirements of the project, usually related to the intended use of the rooms. The main difference between the above mentioned is the level of acoustic insulation. In addition, the selection may depend on special requirements – aesthetic and practical, such as the installation of additional elements such as blinds, etc.
