SOUNDPROOFING PROFILES SOUND RESILIENT MEMBRANES ACCESSORIES

When a body starts vibrating, the particles in contact with it begin to oscillate setting in motion the adjacent ones and generating a perturbation in the object, which spreads to the surrounding environment. This mode of vibration can generate a sound wave that spreads through air, gas, liquid or solid objects with a speed and method that depend on the physical properties of the body.

The sound wave is described by these factors:

Speed c: expressed in m/s, it depends on the physical properties of the body in which the wave spreads;Frequency f: measured in Hertz (Hz) it quantifies the number of complete oscillations made by the sound source;Period T: expressed in seconds (s), it is the inverse of frequency and describes the time required to perform a completeoscillation;Wave length λ: measured in metres (m), it quantifies the distance covered by the sound wave in a period;Amplitude A: expressed in metres (m), it indicates the maximum extension of the oscillation.

Measuring a sound means measuring the sound pressure variation; this magnitude is a force per surface area and the unit of measure used is the Pascal (Pa).Frequency, wave length and speed are linked by mathematical relations: λ=c/f=cT [m]

Each 10 dB increase, is an increase of ten times. For example, a 30 dB sound has ten times more energy than one at 20 dB and 100 times more than one at 10 dB

Since the decibel follows a logarith-mic scale, it can be stated that a 3 decibel increase is equivalent to dou-ble the sound energy

1,000 times approx. more

powerful

The decibel is the logarithmic unit used to measure the level of noise. As it spreads, the sound wave causes a local variation of the atmospheric pressure detectable by the human ear.The range of sensitivity of the human ear to pressure variation is very broad, therefore, its value is expressed with respect to a reference term in loga-rithmic scale. Hence the definition of decibel

3 dB

A value of 65 dB (A) is normally con-sidered for the whole night period (10p.m. - 6a.m.) as the limit for areas with intense human activity. These values are recommended by WHO (World Health Organisation) as the threshold not to be exceeded for public exposure to noise

ACOUSTICS AND LIVING

Thus, acoustic comfort is the condition in which a person's activity is not disturbed by the presence of other sounds and does not suffer hearing injury. In fact, exposure to noise causes psychological disorder and hinders performing the normal activities of a human being, reducing the efficiency and ability to concentrate.

Specifically, in construction, sound is divided into two categories, depending on the mode of transmission:

Wooden structures, like all light constructions, do not have high acoustic performance at low and medium frequencies, in particular with regard to the sound of impact and the transmission of structural vibration by the components making up the structure itself.

For this purpose, we must stop the spreading of waves in order to obtain a reduction of noise transmission using resilient products employed according to the principle of desolidarisation.

Desolidarisation: construction technique or action which keeps elements isolated or separated when contact would allow the transmission of vibrations and, therefore, noise.

Resilient products: elastic separating layers between rigid elements whose main feature is to not allow the transmission of vibrations in the building structure (e.g. impact or noise from footsteps) to its partitions.

Working at this level of the structure means being able to solve the problem at the source, allowing greater flexibility and tolerance during processing and modification of the subsequent layers, such as packages of thermal and acoustic insulation or coatings and various kinds of dry linings.

ACOUSTIC COMFORT

LIVING COMFORT

Structural noise: the sound crosses the structure carrying the vibrations from room to room, even when not directly adjacent.

Airborne noise: the medium carrying the sound energy is air.

While acoustics is the science that deals with sound, architectural acoustics covers the behaviour of the sound wave when it is contained within a boundary, represented by the indoor environments of buildings.The World Health Organisation (WHO) defines the concept of well-being as"the state of complete physical, mental and social well-being and not merely the absence of disease or infirmity".

EXPERIMENTAL ANALYSIS

As we have already mentioned in the catalogue introduction, wood tends to show problems of acoustic insulation at low frequencies, especially with regard to impact noises and the transmission of structural vibration in the building elements. Moreover, this transmission is always affected by how many and which fastening systems are installed to meet the static verification of the building. In this scenario Rothoblaas, together with the University of Bologna, has decided to study this problem in depth. This work proposes to characterise the acoustic properties of monolithic wood structures by investigating the side transmission of different connection systems for CLT panels.

The study aims to identify vibration reduction index Kij and the differential normalised level of vibration Dv,ij,n of different joints in the various connection configurations.The values are evaluated according to Standard ISO 10848, measuring the difference in amount of energy transmitted between CLT panels given a series of mechanical stresses. Several configurations have been considered: the influence of the different anchor plate and structural screw sizes has been evaluated and investigated, as well as the pitch of connection systems, including the nailing and screwing methods.

20 XYLOFON


An abacus of standard connections is provided as a powerful tool to assist designers in predicting the desired acoustic insulation. The availability of this data allows complete characterisation of the structural nodes according to the prediction method proposed by EN 12354-1 and finally offers engineers and architects a powerful tool to assess which solution to adopt in order to obtain the desired noise reduction. The purpose is to contribute to defining the calculation model and provide data for predictive acoustic performance of the CLT structures with respective connections.

Example of use of European Standard UNI EN 12354-1: Acoustics in construction. Evaluations of acoustic performance of buildings starting from the performance of products - Insulation from airborne noise between rooms.

R', apparent soundproofing of the structures involved can be deduced from the following relation:

Where RDd, RFf, RDf, and RFd are the soundproofing values for transmission occurring through the direct path (Dd) and the side paths (Ff, Df and Fd).

For the calculation it is necessary to determine R for the individual paths of noise transmission in the involved structures, through the following relation:

RESEARCH, DEVELOPMENT AND VERIFICATION

30 ALADIN STRIPE


So far we have also considered this formulation for lightweight wood structures, therefore considering the connections between the elements, always rigid and consistent with each other. For CLT structures this is certainly an approximation.Kij depends on the shape of the joint and the type of elements composing it, especially their surface mass. In case of T or X joints, use the following expressions:

Taken from C. Guigan; M.Villot “Junction characteristics for predicting acoustic performances of lightweight wood-based buildings” Proceedings INTERNOISE 2015 , San Francisco, California USA.In the case of CLT structures weakly bound together, the side transmission contribution can be determined according to the following relations, valid if 0.5 < (m1/m2) < 2

Therefore, this transmitted vibration reduction value is obtained: for loads greater than 750 kN/m2 on the resilient layer (XYLOFON/CORK/ALADIN STRIPE) with ∆L minimum = 5 dB

1) Compression or linear load calculation that the product is stressed at under the different walls and in all wall and floor connections. It is advisable to add the permanent load value at 50% of the characteristic value of the accidental load. Qlinear = qgk + 0.5 qvk

It is necessary to think about the limit operating conditions and not the structural limit conditions: in the case of the ultimate limit state of the structure: the designer must choose the corrective factor according to the climatic and operating areas being considered.2) Choose the suitable product according to the table of use. Attention: consider the profile thickness and relative lowering in the panel cuts and project details.3) Calculation of the Kij vibration reduction index between the structural elements according to EN 12354, therefore ∆l, i.e. the effective contribution of the soundproofing strip.

TITAN SILENT ACOUSTICMECHANICAL BEHAVIOUR

TITAN TTF200 ABSORBER PLATE ALADIN STRIPE

The TITAN SILENT system (corner TITAN TTF200 + soundproofing profile) was subjected to a series of tests to understand its acoustic and mechanical behaviour. The experimental test was carried out as part of the Seismic Rev research project with the collaboration of prestigious research institutes in both the academic and industrial sector. The damping capacity of vibrations transmitted by footstep noise of various resilient materials on structural wood elements and the consequent variation of mechanical strength were compared.

SHEAR CONNECTION - WOOD/WOOD

The values of mechanical strength and the methods of installation of TITAN TTF200 are given on page 165 of the catalogue "Plates and connectors for wood".

EXPERIMENTAL PHASE: SOUNDPROOFING

TEST SETUP

REDUCTION OF VIBRATIONS TRANSMITTED BY FOOTSTEP NOISE

The test setup was realised in order to ensure reproducibility of the data and the comparison of results between the various materials. It was decided to pressurise the samples along the z axis using predefined load bands (from 5 to 35 kN/m) as previously tested in institutes dedicated to optimising the resilient capability depending on the type of soundproofing profile. Load variations were possible thanks to a oil-hydraulic press with pressure gauge.

Three wood elements were assembled orthogonally, reproducing the floor-wall node with the interposition of different soundproofing profiles. The principle of the method involves verifying the

difference in terms of vibrational speed between two points on two orthogonal elements and separated by a joint made of TITAN TTF200 with and without the interposition of resilient material and fastening via LBA Ø4 x 60 nails. The stress is generated by the blow of a hammer (weight 350 g) with rubber head, repeating three impulses for each axis of reference. The phenomenon is detected at the same time on two wooden elements where two triaxial accelerometers are installed, connected to a multichannel analyser. The data was sampled in the frequency range between 5 and 5000 Hz, with a time constant of 5 ms.

The presentation of the results is expressed as a percentage of vibration reduction, and as decibels of attenuation of the transmitted noise. For easy reference it was decided to indicate the overall average data at the ends of the provided load bands.The value relating to the average frequencies is the most solid one, from a statistical and methodological point of view. Most of the energy imparted to the sample with the test hammer is concentrated within this range.

TITAN TTF200 + ALADIN STRIPE EXTRA SOFT24% 16%

The data expressed in decibels must only be considered as a comparison between the various materials tested with the same boundary conditions, since it refers to the reduction of noise transmitted on the specific structure, without considering the additional layers composing the whole wall (plasterboard slabs, mineral fibre panels, etc.). Therefore, this data does not express the foreseeable noise attenuation in the finished building.

TEST SETUP

VARIATION OF THE SHEAR MECHANICAL STRENGTH BASED ON THE SOUNDPROOFING PROFILE

The test setup used during the experimental test consists of a metal frame designed in order to apply a static or cyclical action to the connector under investigation, depending on the objectives defined as part of the Seismic Rev research project.In this context we analyse the monotone test results performed through linear load procedures in displacement control, aimed at assessing the variation of the last resistance offered by the TITAN TTF200 connection combined with different soundproofing profiles. The test setup was designed to highlight the behaviour of the

wall-wall and wall-floor connection subject to the forces it must absorb during use. The sample tests are carried out with Xlam (Cross Laminated Timber) panels in resistance class C24 and corner TITAN TTF200 fastened with 60 anker LBA Ø4 x 60 mm nails.

Tests show that TITAN SILENT with ABSORBER PLATE offer a noise reduction of 3.5 dB in comparison to the use of corner TTF200 only, with mechanical stress equal to 60% of those of corner TTF200 (characteristic values found on page 168).The shear resistance of the system (TTF200 + D82361) is greater than 15-20 times in comparison to that of traditional 100x100 mm corners combined with its acoustic profile.

SILENT FLOOR was designed as an acoustic insulating material for absorbing noise and vibrations due to foot traffic. Due to the bituminous base composition it is completely impermeable to air, water and humidity. It restores continuity inside slabs, compensating for any irregularities in traditional structures or dry systems and guaranteeing protection of the underlying structure in the event of equipment failure or leaks

of any kind. The bituminous layer, in fact, is able to adhere and close around connections, compensating for any tears. SILENT FLOOR creates an elastic separation between stiff elements, screed, slabs and walls, dampening vibrations due to foot traffic and to the various sound sources in the rooms.

EXAMPLE OF ESTIMATE CALCULATION OF THE FOOTSTEP NOISE LEVEL AT WORK FOR REINFORCED CONCRETE FLOORS 1 2

20+4 Concrete floor (m1’=300 kg/m2) covered on top by a lightened layer (m2’=300 kg/m2 and thickness 10 cm) for installing systems and with floating screed in cement sand with interposition of a resilient material. Total surface mass = 330 kg/m2 Resilient layer dynamic stiffness s’= 27 MN/m3

Use the following formula to calculate the sound pressure level transmitted by the structure without resilient material:

To calculate the reduction of noise from foot traffic, given by the resilient material:∆Lw = 13 log(m2‘ ) - 14,2 log(s‘ ) + 20.8dB = = 13 log(100) - 14.2 log(27) + 20.8dB = 26 - 20.3 + 20.8 = 26.5dB

52 SILENT WALL



SILENT WALL is used to improve the sound properties of plasterboard wall, slabs and insulating false ceilings. It is also used to cover wooden roller shutter boxes in order to improve the soundproofing of the façade or to damp vibrations on metal sheeting. SILENT WALL can replace plaster and rough coating on air gaps in conventional double wall constructions. It is highly resistant to water vapour transmission and is used as a vapour barrier when laid on the warm face of fibre insulation on external walls. SILENT WALL reduces laying times as it requires no nails. Simply remove the silicone film and press the sheet onto the surface to be insulated. To ensure the stablest and most compact adhesion to the surface that

SILENT WALL is applied to, said surface must be suited for gluing and must be clean, smooth and compact (do not apply on surface finishes which could become detached from the surface such as sand, wood shavings or residues form previous works).Do not lay using the glue-only method at temperatures below +5 °C or use warm air or flame devices.

The TRASPIR 3D COAT breather membrane is placed parallel to the eaves, starting from the bottom edge of the roof. The second layer must overlap at least 10 centimetres over the first layer. Each layer must be fixed to the support with a mechanical fastening device (e.g. hammer, pneumatic or manual stapler). The fabric can be applied over the insulation on a continuous support, such as a wooden plank. Once you reach the top of the roof, it is advisable to have the membrane protrude beyond the ridge line by at least 10 centimetres for best overlapping with the fabric layers, which will overlap on the other layer of the roof. We also recommend overlapping the fabric by at least 10

centimetres in the butt joints.For a correct air or water sealing, please use DOUBLE BAND, MEMBRANE GLUE, FLEXI BAND or FROST BAND.

LABORATORY MEASUREMENT

The test sample is identified by a 5.60x3.65 m wooden roof positioned between an emitting room (photo 1) and a receiving room, able to emit and record the sound stress applied during the tests.

Shown here is the stratigraphy tested in the two versions: the first with the TRASPIR 3D COAT and the second with the sheet metal directly on the plank.

The following measuring tests have been performed on both stratigraphies, with and without TRASPIR 3D COAT:

Airborne acoustic insulation and noise generated by heavy rain

1 0.6 mm thick galvanised steel sheet metal 2 8 mm thick TRASPIR 3D COAT deadening insulation

3 20 mm thick pine beads 4 60 mm thick pine battens5 1 mm thick breather membrane

6 22 mm thick 200 kg/m3 wood fibre 7 180 mm thick 110 kg/m3 wood fibre

8 0.6 mm thick vapour retardant 9 20 mm thick pine beads10 200 mm thick laminated pine beam

TESTS PERFORMED

RESULTS

1. Airborne acoustic insulation according to EN ISO 10140-2:2010 and EN ISO 717-1:2013 on roof. The result is a soundproofing power index of the stratigraphy RW. Accordingly, the higher the value the better the acoustic insulation.

2. Noise generated by heavy rain according to EN ISO 140-18:2007: in this test you obtain a value indicating the sound pressure level LIA recorded in the receiving room during the pounding of water, simulated by a tank placed over the sample.

10 TIPS FOR FOAMING CORRECTLY

1. Shake the can at least 15-20 times before use.2. The surfaces must be load-bearing, clean and free of dust, dirt or solvents.3. Both the substrate and the foam surface must be moistened, we recommend using 1 dl of water per can.4. If sufficiently humidified, the foam expands 3-4 times its volume.5. The ideal temperature of use is approx. 20°C. In case of excessively high or low temperatures, cool or heat the cans with water.6. We advise against using the foam at a temperature below 5-7°C (the product may not adhere to the surface). 7. Any foam residues must be immediately removed before the foam hardens.8. To avoid damaging the connection thread of the can, place it on a flat surface and slowly tighten the gun. Can and gun must not be relieved of pressure, so it is important not to leave empty cans tightened on the gun. 9. If there is hardened foam in the gun, it is unusable. If not used for long periods, clean the gun thoroughly with specific detergent. 10. Store the product properly, following the instructions on the package or on the can.

EXAMPLE OF FOAM YIELD CALCULATION Starting from a 1x1 cm crack, we obtain a surface of 0.0001 m2. One cartridge is equivalent to 0.038 m3 (38 l) therefore, it allows filling a 380 m long crack.These values are guaranteed by a correct use of the product, following the application instructions below.
