Definitions

  • the invention relates to the field of construction, especially to window construction elements, which reduce indoor noise contamination. More especially it relates to a device for reducing the rain made noise level on windowsill.
  • One of the most important aims of the EU guidelines is to achieve outdoors noise level decrease till 55dB at night. (http://ec.europa.eu/health/ph_projects/2003/action3/docs/2003_08_frep_en.pdf)
  • Windowsills in majority of the modem buildings, including residential buildings are made from metal or plastic plate. Usually this plate is constructively associated with the window frame. In such a way windowsill vibrations are introduced indoors and often cause the resonance of window construction elements, which increases the noise.
  • Preferred embodiment should be useable for windowsill, reachable from outside without technical devices and also be adjustable for individual residential usage.
  • Typical characteristics of rain must be cleared out for construction of suitable device for lying on the windowsill.
  • Type of rain describes several parameters including height of raindrop falling, intensity (liters of water per square meter) and average drop diameter.
  • Rain classification IEC 60721-2-2 specified in Table 1 can be taken as a reference to determine the frequency of different intensities. Table 1. Classification of environment conditions by IEC 60721-2-2 Ed. 1.0 b: 1988 part 2: Environmental conditions in nature. Precipitation and wind.
  • Polyurethane foam plate with thickness 10 to 25 mm was used for noise reduction. Preliminary experiments showed that the device with thickness less than 15 mm as well as the increase of thickness over 20 mm do not provide adequate efficiency. That is why 16 mm thick polyurethane foam level was used for further researches.
  • Size of raindrops can be from 2 till 5 mm during very heavy rain.
  • raindrop In order to achieve power dissipation in noise reduction device, raindrop must stuck on surface of the device or must be broken down into several parts that get stuck in pores. In such way raindrops with diameter to 2 mm can stuck in device pores separating surface with diameter 1.6 to 2.2 mm without breaking down and with breaking in 1-4 parts if diameter is up to 5 mm.
  • the most important parameter for selection of noise reduction device is density of material. Water accumulation in material upper part can be observed in high density wherein noise reduction effect is minimal. If material density is to small - opposite situation can be observed - raindrops with high falling speed can break through material layer and reach the windowsill. In this situation the best effect of noise reduction is not reached as well. That is why the optimal noise reduction could be made by reticulated polyurethane foam material with open pores, with average pore count 5 - 6 cm -1 , density 29 kg/m 3 , hardness 2.7-4.7 kPa, durability 80 kPa, 120% (relative) elongation before breaking.
  • Proposed device for noise reduction of falling rain made noise provides noise reduction for 88 - 92% expressed as increase of background noise for 2 - 3%.
  • Device fixation on windowsill is easy and do not ask any special technical skills, with suitable glue or self-sticking type. Fixation can be done in short time on any floor of the building. Size of material can be adjustable to windowsill size during production or at the place of usage. Material of device does not accumulate dirt, avoid plant growth on it and is fire safe (flame retardant).
  • Additional advantage is that it protects windowsill from bird stay. Bird claws stuck in the pores and complicate the taking off, so they do not get back anymore.
  • the present invention provides a device for reduction of noise of falling rain for metallic or plastic windowsill of window, wherein an upper surface of the windowsill is covered (glued) by noise reduction device.
  • a noise reduction device is polyurethane foam layer. Thickness of the device is about 15 - 20 mm, optimal 16 mm, amount of pores is 5 - 6 pores on 1 cm 2 , density 29 kg/m 3 , hardness 2.7 - 4.7 kPa, durability 80 kPa, 120% (relative) elongation before breaking.
  • polyurethane foam contains additives that avoid plant growth on it.
  • Material is fire safe (flame retardant).
  • polyurethane foam layer has one self-sticking layer, which keeps cover connection with metallic or plastic windowsill for long term.
  • Device can be industrially produced in several colors, for different sized standard windowsills or can be adapted by cutting at the place adjusting to windowsill size during production or at the place of usage. Installation does not need any special technical skills, it is fast and safe, can be done from the indoor of the building. Device traits and effectiveness is shown below described examples.
  • Device can be industrially applicable for new buildings during construction, for reconstruction of existing buildings or individual windowsill covering.
  • Material for described device can be industrially produced with different colors, with self - sticking layer, what simplify the application.
