The acoustic performance of our products should be assessed within a specific build-up, rather than solely on the insulation board. We have tested a wide range of acoustic solutions and we can also carry out guideline project specific calculations, on request.
We’ve had a series of acoustic tests completed showing great results for rain impact noise with steel and timber deck flat roofs insulated with Kingspan Thermaroof products and Kingspan OPTIM-R vacuum insulation panelss. A test result of 27.5 LIA (dB) was achieved for a green roof build-up insulated with 100 mm Thermaroof TR26/TR27 LPC/FM. An assessed test result of 41.6 LIA (dB) was achieved for a metal deck flat roof build-up insulated with 100 mm Thermaroof TR27 LPC/FM.
Acoustic tests were also completed for airborne sound transmission with steel and timber deck flat roofs insulated with Thermaroof products and OPTIM-R vacuum insulation panels, and also steel frame walls insulated with Kingspan Kooltherm products. A test result of 47 Rw (dB) was achieved for a metal deck flat roof build-up insulated with 150 mm Thermaroof TR26 LPC/FM. An assessed test result of 51 Rw (dB) was achieved for a metal deck flat roof build-up insulated with 60 mm Thermaroof TR26 LPC/FM. A test result of 62 Rw (dB) was achieved for a steel frame wall build-up insulated with 60 mm Kooltherm K15 Rainscreen Board.
