Inter-apartment walls (i.e., walls between two apartments or between common areas of the building and households) must meet certain requirements for acoustics and fire resistance. If the acquisition costs of these walls are lower, and the wall itself is narrower while maintaining all parameters, it allows for better floor area utilization and increases the valuable area of the apartment. These are certainly not negligible advantages. Let us take a closer look at some technical parameters of selected types of inter-apartment walls.
Fire Safety
According to ČSN 73 0802 Fire Safety of Buildings - Non-Production Buildings Article 8.1.2, the required fire resistance of fire walls on above-ground floors is: 60 minutes for the IV level of fire safety of the fire section, 90 minutes for the V level of fire safety of the fire section. Each apartment in residential buildings is considered a separate fire section (see ČSN 73 0833 Fire Safety of Buildings - Buildings for Residential and Accommodation).The fire resistance for both IV and V levels is met by Rigips and Duragips safety structures as well as masonry partitions.
Acoustics
The requirement for the weighted sound insulation of the wall: R´w = min. 52 dB (according to ČSN 73 0532 “Protection Against Noise in Buildings”)In contrast to a single layer of porous concrete blocks, Rigips and Duragips safety partitions meet the air sound insulation requirements for inter-apartment walls.
Wall Thickness and Construction Costs
There is no standard that defines the ideal wall thickness or construction costs. However, we live in a market economy where every extra centimeter plays its role and every additional koruna earned is appreciated.Rigips and Duragips safety partitions have significantly smaller construction thickness than masonry partitions with comparable parameters. They allow better use of space and primarily offer an increase in the area of the apartment, which is key to significant economic benefits.
Example:
To illustrate, we present one example of cost savings when designing a Duragips 3.38.02 partition compared to a solid masonry partition.
In the calculations, we consider an average apartment in the Czech Republic with an area of 68 m² and an average length of inter-apartment walls of 15 m.
Cost of Duragips partition with a thickness of 126 mm (no plaster needed) 1,160 CZK/m²
Cost of a masonry partition made of brick blocks with a thickness of 300 mm including plaster 1,770 CZK/m²
Price difference for a partition height of 3 m in favor of the Duragips partition 1,830 CZK/bm
Total price difference in costs for acquiring an inter-apartment partition for this apartment unit: 27,450 CZK (1,830 CZK/bm x 15 m)
Using the Duragips partition increases the area of the apartment by approximately 2.6 m². The economic benefit of these precious 2.6 m² can be easily calculated depending on the location and market value of 1 m² of apartment space.

The building-technical parameters and prices of masonry partitions are based on publicly available technical documentation and information provided by manufacturers of brick blocks.
The building-technical values of Rigips and Duragips inter-apartment partitions are based on measured parameters.
Prices are indicative and excluding VAT. They include direct material, direct wages, and machine costs.
Rigips Safety Partitions
are constructed both structurally and technologically from standard drywall partition structures. To enhance safety, two layers of steel sheet and reinforcements from CD profiles are integrated into the construction. |
