H1：What Rock‑Wool Density & Size Do I Need For My Project?
Many international contractors and importers come to us with practical questions about rock‑wool density and board dimensions. Below are real search‑style questions frequently raised by our global customers.
What rock‑wool density should I use for partition and ceiling sound absorption?
A: For interior partition walls and ceiling acoustic absorption, 40‑60 kg/m³ is the recommended density range. It delivers good sound‑absorbing performance without extra unnecessary cost.
Which rock‑wool density fits facade filling and sandwich panel core?
A: 80‑100 kg/m³ is widely used for facade cavity filling and as sandwich panel core material, balancing mechanical strength and cost‑efficiency.
What density of rock wool works for high‑rise external wall thin‑render systems?
A: For high‑rise external wall thin‑render insulation projects, choose 100‑140 kg/m³ rock wool to meet tensile strength and wind‑load requirements.
Should I use above 140 kg/m³ rock wool for heavy‑duty facade, fire‑stop and marine projects?
A: Yes. Density above 140 kg/m³ is preferred for heavy‑load facade systems, fire‑stop sealing and marine‑grade insulation applications.
Is higher rock‑wool density always the better choice?
A: Definitely not. Higher density brings extra material cost and may not add practical benefits. Project selection shall consider building codes, wind‑load and system design. Contact us for free professional suggestions.
What standard sizes do Taishi rock‑wool boards come in?
A: Our standard stock dimensions are 1200×600 mm and 1200×150 mm, with thickness ranging from 30 mm to 200 mm.
Can I order custom‑specification rock wool from Taishi?
A: Yes. We support custom density, special thickness, aluminum‑foil facing and fiberglass‑cloth facing. Custom cut‑to‑size for automatic composite panel production lines is also available.
Please send your specifications or drawings in your inquiry, and we will confirm feasibility and production lead‑time for you.
