The different levels of acoustic partition ratings meet different requirements, with the acoustic screens available in both single and double glazed and available with or without a frame. The higher the OITC rating, the better resistance to sound transmission. Trosifol® Sound Control has all the outstanding security properties of standard laminated glass, as well as high sound insulation values, up to 2 dB better than float glass of the same thickness. • Door openings rated STC 55+ can only be achieved with doors that are sound measures at 70 dB on one side of a parti-tion, and only 40 dB on the other, the TL rating would be 30 dB at that particular frequency. 4 %âãÏÓ 12 0 obj > endobj xref 12 42 0000000016 00000 n 0000001403 00000 n 0000001513 00000 n 0000002267 00000 n 0000002588 00000 n 0000003223 00000 n 0000003336 00000 n 0000003459 00000 n 0000003555 00000 n 0000004139 00000 n 0000004767 00000 n 0000006486 00000 n 0000006916 00000 n 0000007030 00000 n 0000007426 00000 n 0000007903 00000 n 0000009697 00000 n 0000014031 00000 n CT Glass offer a range of laminated and toughened laminated glasses incorporating a special acoustic interlayer by TROSIFOL. 8mm laminated safety glass 2 6. 41dB (Rw) K35-AP-02. 6. the performance of a 6/12/6 insulating glass unit is now written; Rw(C, Ctr) = 33(-1;-3). Having determined the noise source level rating and the desired internal noise level for a given room, the next step is to find a glass product from Table 1B which meets or exceeds the This document presents an overview of glass acoustical performance and considerations when specifying glass to achieve specific acoustical objectives. Laminated and double-glazed glass both hold STC ratings of 40, but anything higher typically requires a combination of the two. Overview soundcontrol glass. Selection of suitable glass Acoustic Glass This section provides only an introductory guide to control of noise using ST125 400HZ (DB) INTERIOR STC RATING 6. 5mm Toughened Laminated: Glass with Bubble Joint. Use different glass thickness for individual glass lites, i. The below gives a guide to the acoustic levels and their suitability for your needs so you can be well informed when choosing your acoustic partition. Of course if we compare a 6 mm-monolithic with a double glazed 12-6-10 mm, the sound reduction is much better at the double glazed unit. TL6332 35 28 4mm Temp. R w = 42 (-1; -5) R w For example, if an 80 dB sound on one side of a wall/floor/ceiling is reduced to 50 dB on the other side, that partition is said to have a STC of 30 dB. 8mm 40 A1 Reduces UV radiation by 99% reducing fading up to 8. When to Use Acoustic Glass. ‘Rw’ is the weighted sound reduction in decibels which allows for a correction for the human ear’s response and this is the most commonly used term when specifying noise reduction values. in windows and doors are becoming far more important. 8 Pilkington Optiphon™ 16,8 41 -1 -3 16. 87 Light Reflection 0. 24 mm) 1/8" 0. through glass exhibits coincident and resonance effects. 16mm AIR 6mm Lam. 8. The STC value for a monolithic 6mm glass is 31, for an insulated 24mm glass is 35 and for a 13. Except for acoustic value, Luminous Factors, Energy Factors, Solar Factors, Thermal Transmission, Color In this example, the reduction factor is –1 db, which gives a total acoustic value of 41 dB, and the reduction factor Ctr is –5 dB which gives a total acoustic value of 37 dB. dBA: Sound level measured with an A‐weightedmeter to reflect the sensitivity of the human ear. 52mm 5mm glass x 1. Neoprene acoustic seal Painted steel capping Glass size and glazing system will affect STC rating. STC ratings are used for windows doors, walls & most building materials. Noise intensity is measured in Decibels (dB) and the scale used to measure levels of noise reduction is known as the sound reduction index. 4 CF 377 1(B)1 41 dB Rw Pilkington Optiphon™ – acoustic performance data Glass types Acoustic performance data [dB] Total thickness R [mm] w C Ctr Single glazing Pilkington Optiphon™ 6,8 36 -1 -4 6. 8mm), however, at that thickness the glass becomes very heavy, making it difficult to support with traditional window designs. 8 1 For more information visit viridianglass. Costing more than other materials, this is used mainly for exterior applications. This is typically plastic polymers: PVB, EVA, TPU, or resin. Laminated glass is made up of two panes of glass pressed together with a polyvinyl butyral inter layer. Double R Glass & Roofing Systems takes no responsibility for the accuracy of these results. Options. tel: 0121 667 9089 dB Rating; Certificate No. A glazing unit can be assembled using standard glass, acoustic glass, laminated glass, security glass or combinations of these glass panes. This critical frequency changes with the glass thickness, in effect moving towards lower frequencies as the glass gets thicker. 4 CF 377 1(B)1 41 dB Rw At a glance Dimension: Height -up to 3000mm Fire ratings: N/A Acoustics: Up to 39dB (Rw), Structure: Up to severe duty Deflection head: +/-15mm, +/-25mm Page 2/3 Acoustic Technical Information Float mm Rw (dB) 3 , 4 30 5 , 6 31 8 34 10 35 12 37 19 39 Duo Plus™ IGU with Float mm Rw (dB) 4/12/4 32 5/12/5 33 E413-87 in an ac oust ical wall. 4mm Acoustic: 30 dB Rw: 37 dB Rw: 7 dB Rw: 35%: Existing Sealed Unit - 4mm / 6 - 16mm / 4mm Glass Retain & add: Secondary Glazing - 100 Cavity - 6. Author: pmn. Various performances can be achieved by combing different types of glass thickness and number of interlayers. 8mm Acoustic / 16 spacer /6mm IGU 38 dB 36 6. 8MM ACOUSTIC LAMINATED Keywords: Laminated Safety Glass Glass data sheets are available to view and download. and further development of high-rise buildings, acoustic qualities .

Acoustic glass consists of two panes of glass which have been laminated together using PVB (Polyvinyl Butyral). 5 W/(m ,K) RADIATION PROPERTIES Light Transmittance 0. Laminated glass consists of two Dec 11, 2012 · The acoustic attenuation of a 6-12-6 mm glass is generally superior to that of a monolithic 6mm-thick glass, but only by 2 or 3 dB, and still there may be low frequency bands where the DGU performs worse. 4mm Acoustic Glass: 29 dB Rw: 35 dB Rw: 6 dB Rw: 30%: Existing Sealed Unit - 4mm / 6 - 16mm Gap / 4mm Glass Remove & replace with: New Sealed Unit - 4mm / 6 - 16mm Argon / 6. dB: Decibel is a ratio of the measured sound pressure level compared with the quietest sound a person can hear. 14mm AIR 6mm Lam. g. BIM Objects Enhance your digital specifications with our customised BIM files designed for specific glazing applications. Acoustic glass is standard glass coated with an acoustic film on the side facing the air-gap, so it cannot be touched or wiped, as it is easily otherwise scratched. Glazing Options • Laminated Safety Glass • Tempered Safety Glass • One-Way Vision Mirror • Non-Reflective, Heat Resistant • Bullet Resistant • Polycarbonate • Wire-Inserted Safety Glass It is an International Organization for Standardization (ISO) rating and part of the ISO 140 (Acoustic) family. 1 mm glass plus 0.

The STC (Sound Transmission Class) rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. 08kg/m2 Other types of acoustic glass are available and can achieve Rw values up to 58 decibels. Glass size and glazing system will affect STC rating. 0 airgap/3mm) is 30. 1. Acoustic glass can consist of more sheets of glass and bonded internal layers if desired, making it even tougher for sound to pass through – especiall glass products for buildings in noisy environments. For 4 mm monolithic glass, the critica! frequency is 3 000 Hz, whilst for 13 mm thick plaster it is 3 200 Hz. All glass has The SRI is measured by testing a partition sample for resistance to the passage of airborne sound in an acoustic laboratory in accordance with EN ISO 10140-1 & 2. 10mm float // 6mm float 40 38 35 Heavy and different thicknesses.
