“My company specialises in basement conversions, which come in many shapes and sizes – some customers are looking for an additional room for an office, kitchen or bedroom, others a home cinema or pool and others just need storage space.

Basements have demanding performance requirements: fire protection, thermal protection, moisture protection and sound insulation. I choose Siniat’s Aqua Board because it can meet these requirements in a single board.”
