understand. Sound insulation and other requirements, as long as the overall heat transfer coefficient is below 1.8, your sound insulation and heat insulation, or other aspects, are no problems and can meet the standard?
Got it. Soundproofing and other requirements, as long as the heat transmission coefficient of 1.8 or less overall, your sound insulation and insulation, or other aspects are no problem, can meet the standard?
Understand? For sound insulation and other requirements, as long as the heat transfer coefficient is below 1.8, your sound insulation and heat insulation, or other aspects are all OK, can all meet the standard?<br>
