Waterproof Tile-Ready Boards for Corners, Angles & Pipe Concealment
Purpose-built XPS foam boards designed for creating clean room corners, wall angles, and boxing in water pipes, waste pipes, and heating risers — fully waterproof, tile-ready, no timber framing needed.
Insutile® Angle Boards are specialized tile backer boards engineered for two key applications: forming clean internal and external room corners and wall angles, and concealing exposed plumbing, heating pipes, waste stacks, and service risers. With Insutile® Angle Boards, there is no need for timber battens, plasterboard, or separate waterproofing membranes.
The boards are cut to size, assembled with polyurethane adhesive, and sealed at the joints — creating rigid, fully waterproof corners and enclosures that can be tiled directly. Whether you need a perfect 90° wall junction or a clean pipe boxing, Angle Board delivers.
No timber framing required — boards assemble into rigid enclosures with adhesive alone.
Cementitious surface accepts adhesive and grout directly without primer.
Insutile® Angle Board delivers superior performance for room corners, wall angles, and pipe concealment:
Complete water resistance for kitchens and bathrooms. No separate membranes needed.
Angle Board's integrated waterproof construction is essential for protecting corner junctions and wall angles in wet areas. The XPS foam core and cementitious coat create a seamless barrier that prevents water ingress at critical connection points where pipes and walls meet, eliminating the need for separate membrane systems and ensuring long-term durability in bathroom and kitchen installations.
Rigid assembly with adhesive alone. Eliminates need for timber battens or plasterboard.
Angle Board's inherent rigidity makes it ideal for creating independent corner formations and pipe enclosures without structural support behind them. Simply apply polyurethane adhesive along the edges, and the boards bond together to form a self-supporting assembly ready for tiling, making it perfect for boxing pipes and forming clean room corners in any room configuration.
Cementitious surface bonds perfectly with any tile adhesive and grout system.
The cementitious coating on Angle Board creates an ideal surface for direct tiling of corner junctions and angled pipe boxing enclosures. Standard thin-set and grout systems provide exceptional adhesion, allowing tiles to be applied immediately without primer, ensuring professional finishes in corners and concealed pipe runs with superior bond strength.
Slim profile boards maximize usable floor or wall space in tight installations.
When creating corner formations and boxing pipes in kitchens and bathrooms, every millimeter counts. Angle Board's slim profile delivers structural support and waterproofing in minimal thickness, preserving valuable floor and wall space compared to traditional timber-and-plasterboard solutions, without compromising protection or durability.
XPS foam and cementitious coat prevent microbial growth and degradation over time.
Corner junctions and pipe enclosures are prone to moisture accumulation. Angle Board's XPS core and mineral surface resist biological colonization, keeping interior corners clean and hygienic even in high-humidity bathrooms and steamy kitchens. This prevents unsightly discoloration and maintains structural integrity for decades.
Easy to handle and transport. Reduces installation labor and fatigue.
Unlike traditional timber and concrete alternatives, Angle Board boards are easy for one person to position and hold during assembly. When forming corner junctions or concealing pipe runs, the lightweight material reduces installer fatigue and allows faster maneuvering in confined spaces like bathrooms and kitchens.
Simple tools required. Boards cut cleanly for angles, curves, and custom shapes.
Form complex corner configurations and custom pipe enclosures with basic hand or power tools. Angle Board cuts cleanly without delamination, allowing precise mitres at corners and clean holes for pipe penetration. Polyurethane adhesive and simple assembly means no specialized installation expertise needed.
Skip the timber battens and plasterboard layers. Faster, cleaner installations.
Traditional corner and pipe boxing require multiple layers of timber, plasterboard, and waterproofing membrane. Angle Board combines all functions in one board, eliminating frame construction, reducing material waste, accelerating installation schedules, and delivering cleaner, more durable corner formations in kitchens and bathrooms.
Easily create removable panels for valve and fitting access.
Angle Board's modular structure makes it simple to integrate removable access panels into pipe enclosures and concealed corner installations. Provide easy maintenance access to valves, shut-offs, and service points without disrupting tile finishes or compromising the aesthetic appearance of corners and boxing.

Seven essential steps for successful corner, angle, and pipe boxing installation:
Measure corner junctions, wall angles, or pipe runs and plan board layout for optimal coverage and access.
Cut boards to required dimensions using standard hand or power tools.
Apply polyurethane adhesive to board edges for assembly.
Position and press boards together to form the boxing enclosure.
Tape and seal all joints with waterproof sealing tape.
Clean and prime the surface if needed before tiling.
Install tile directly onto the cementitious surface with standard adhesive.
