We are looking to source high-quality Calcium Silicate Boards for fireplace enclosures and thermal insulation. Key specs include specific sizes, density around 225 kg/m³, and an initial order of one full 20ft container. Our main choice is grey boards similar to European standards, but if those aren't readily available, please share details and pricing for standard white options that fit these needs. Additionally, we're also interested in BIO soluble blankets and ceramic fiber blankets. Please provide your product availability, specifications, and pricing for these items as well.
