The legal basis for the observance of sound levels pertaining to technical building systems (installation noise)

is specified in DIN 4109. Accordingly, a minimum sound insulation of 30 dB (A) is generally applicable for sound-

protected interiors such as living rooms and bedrooms. This value must be adhered to in every case. In addition,

lower sound levels can be contractually agreed upon.

General informationSound protection - Implementation in practice

The acoustic outcome of all works in the installation depends on various

factors. Below you will find some valuable tips to check at the construction

site, which are often ignored or are not met. The fitter often has to deal

with inappropriate conditions particularly in terms of the wall quality

which he should examine technically and for legal liability. 220 kg/m2

Wall thickness 17.5 cm

180 kg/m2

Wall thickness 11.5 cm

Metal stud wall only with Certificate of suitability

Install only tested and marked fittings! The individual, installed fittings and appliances must be tested and marked in terms of their fittings noise level and associated fittings noise class.

For a pressures of more than 5 bars, use a pressure reducer!In order to prevent flow noise, the resting pressure from floor distribution must not be more than 5 bars.

Observe dimensioning, Always open shut-off valves in operation! The actual flow must not be higher than the flow based on which the classification is made. Accordingly, the spout devices such as shower heads or jet regulators must not belong to any higher flow group than the fitting itself. Passage fittings must not be used for throttling.

Appropriate suitability certificates must be available for all walls whose mass per unit area is less than 220 kg/mm2 . The mass per unit area of a single-leaf wall, which should be mounted on or in the fittings or water installations including waste water, must be at least 220 kg/m2 according to DIN 4109. For lighter solid and dry walls, an acoustic suitability certificate according to DIN 4109 is always required.

Fittings of the fittings group II should not be mounted on walls that border rooms requiring protection on the same floor or in the floors above or below.

Additionally, note: Installation noise level lowers with high quality pipes. The ground plan, the construction and/or the specified cable routing sometimes necessitate drain pipes with a better sound reduction index than HT pipes.

Suitable expansion strips should be used before placing the screed.No sound bridges should arise between installations or installation walls and floating screed.

For Burda MEROBLOCK, the test set-ups are aligned to facilities in surgeries consistently and according

to the conditions on the building site. For maximum safety in design and installation.

General informationSound insulation - Test certificates and installation situation on site

To achieve the required noise protection level, it is important for

planners and installers to know the values of the individual com-

ponents of the sanitary systems. For this purpose they use the

acoustic test reports of the manufacturer.

Fundamental to the success of their work is that the test set-up for

the sound level measurement is as close as possible to the set-up of the

later installation. Therefore, they should always ask for the test reports

and compare the test set-up with the proposed installation!

Result: Lowest noise level in practice

General informationBarrier-free construction according to DIN 18040, solutions with Burda MEROBLOCK

The Burda MEROBLOCK offers the right connection options in any installation situation, making it a univer-sally applicable choice at the construction site. Whether brick or dry wall construction, the demands on high quality or standard-compliant facilities for barrier-free living can always be met.Examples of the implementations of the requirements according to DIN 18040 with the Burda MEROBLOCK Installation blocks:

The Burda MEROBLOCK range includes not only standard-compliant in-

stallation blocks with dimensional requirements and increased resilience,

but also barrier-free sanitary systems.

Various designs such as the wash-stand flush-mounted siphon, the electrical

and electronic WC actuation and wash-stand fittings engineering meet the

most varied requirements.

The Burda MEROBLOCK mounting plates are particularly designed for

the high load (100 kg) of the folding support handles. In addition to

the original dimensions of the manufacturer's mounting, these parts

include standardised clearance dimensions and a practical design for

brick and dry wall construction.

The high quality standardised sound protection through the structure-

borne sound insulation design can be further improved in bricked front

walls by the use of noise protection cages.

The optical / electrical and contactless Burda WC control allows a toilet

flushing that suitably meets the standard and usage in barrier-free bath-

rooms.

General informationBarrier-free construction according to DIN 18040

Requirement according to DIN 18040

Movement area in front of the wash-stand. Right, left or cen-

tral arrangement possible. Adequate knee space should be

provided for wheelchair users in the area of the wash-stand.

For this purpose a flat, surface-mounted or a flush-mounted

siphon is provided.

Requirement according to DIN 18040

A movement area 1500 x 1500 mm should be provided in front

of bathtub or in the area of the shower. An appropriate spatial

planning for retrofitting a shower place with a bathtub is recom-

mended.

Barrier-free wash-stand facility Barrier-free bathtub and shower area

Requirement according to DIN 18040

WC seat height 48 cm, including seat.

In the toilet, a movement area is necessary in front and also to

the right and left of the toilet. The toilet flushing must be oper-

able on both sides with the arm or hand, without changing the

seating position. For barrier-free, wheelchair-accessible flats,

only a lateral movement area to the right or left of the toilet is

provided according to DIN 18040.

Movement and spacing areas according to DIN 18040

Movement and spacing areas should be in concordance with

rules and standards in barrier-free construction An important

reference point for this is the manoeuvring space for wheel-

chairs; this is the reason why the movement area according to

DIN 18040 provides 1500 x 1500 mm space for wheelchair users

in public areas and in homes. In other flats, this area is deter-

mined according to DIN 18040 at 1200 x 1200mm. Movement

areas for different installations can overlap.
