Waterproof Polyurethane Foam Ceiling Partition Board 1200x600mm Multiple Thicknesses for Bathroom Basement Soundproofing Moisture-proof Heat Insulation
1200x600mm Waterproof Polyurethane Foam Ceiling Board for Soundproof and Moisture Control

This polyurethane foam partition board provides a practical solution for interior spaces that need protection from moisture, sound transfer, and heat loss. Whether you are finishing a basement, constructing a bathroom partition, or adding insulation to a ceiling, this board offers a rectangular 1200x600mm format with thickness options from 10mm up to 50mm. The Grade A material ensures consistent quality across all sizes, and the board is explicitly designed to be waterproof and moisture-proof, making it suitable for damp environments where standard gypsum or timber would deteriorate. Its lightweight nature simplifies handling and cutting on site, reducing installation time compared to heavier alternatives.
Features and Construction

Every board in this range shares the same 1200x600mm footprint, allowing you to choose the thickness that matches your specific insulation or soundproofing requirement. The material is extruded polyurethane foam, a closed-cell structure that resists water absorption and provides a thermal break.
Material and Build
Manufactured from Grade A extruded polyurethane foam, each board offers a dense, uniform structure. The closed-cell composition prevents moisture ingress, making it ideal for bathroom and basement environments. The rectangular shape ensures close-fitting installation with minimal gaps when butted together.
Size and Practical Fit
Standard dimensions of 1200mm by 600mm fit common ceiling grid systems and wall frameworks. The thickness range – 10mm, 12mm, 20mm, 30mm, 40mm, and 50mm – gives you control over the level of soundproofing and thermal insulation without changing the board footprint.
Uses and Placement

These boards are designed for interior use on flat surfaces where water resistance and acoustic performance are priorities. They can be applied to ceilings, internal partition walls, and floor underlays in residential and commercial settings.
Event or Professional Use
For builders and contractors working on bathroom or basement refurbishments, the waterproof nature of the board eliminates the need for separate vapour barriers. The 1200x600mm size matches standard ceiling tile dimensions, simplifying replacement in suspended grid systems.
Everyday Home Use
Homeowners can use these boards to line a home cinema wall for reduced sound transmission to adjacent rooms, or to insulate a cold ceiling in a loft conversion. The moisture-resistant property also helps prevent mould growth behind partitions in high-humidity areas.
Benefits and Buying Value

Choosing a single material that combines waterproofing, moisture resistance, and soundproofing reduces the number of layers needed in a build. The multiple thickness options allow you to buy precisely the board depth required for your project.
Reuse and Low Maintenance
Polyurethane foam does not rot or absorb water, so the boards remain effective over time with minimal maintenance. They can be painted or covered with wallboard if desired, extending their lifespan within the building fabric.
Why Choose This Product
If you need a single material that handles damp conditions, reduces sound, and provides thermal insulation, this Grade A polyurethane foam board delivers all three functions in one rectangular tile. The 1200x600mm format and six thickness choices give you flexibility without compromising on performance.
