Angle Board

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.

What is Insutile® Angle Board?

Corners, Angles & Pipe Boxing — One Board Does It All

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.

Self-Supporting Structure

No timber framing required — boards assemble into rigid enclosures with adhesive alone.

Tile-Ready Enclosure

Cementitious surface accepts adhesive and grout directly without primer.

Key Features & Benefits

Insutile® Angle Board delivers superior performance for room corners, wall angles, and pipe concealment:

Waterproofing

Waterproofing

Complete water resistance for kitchens and bathrooms. No separate membranes needed.

Waterproofing

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.

Self-Supporting Structure

Self-Supporting Structure

Rigid assembly with adhesive alone. Eliminates need for timber battens or plasterboard.

Self-Supporting Structure

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.

Excellent Tile Adhesion

Excellent Tile Adhesion

Cementitious surface bonds perfectly with any tile adhesive and grout system.

Excellent Tile Adhesion

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.

Compact & Space-Efficient

Compact & Space-Efficient

Slim profile boards maximize usable floor or wall space in tight installations.

Compact & Space-Efficient

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.

Mold & Mildew Resistant

Mold & Mildew Resistant

XPS foam and cementitious coat prevent microbial growth and degradation over time.

Mold & Mildew Resistant

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.

Lightweight

Lightweight

Easy to handle and transport. Reduces installation labor and fatigue.

Lightweight

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.

Easy to Cut and Assemble

Easy to Cut and Assemble

Simple tools required. Boards cut cleanly for angles, curves, and custom shapes.

Easy to Cut and Assemble

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.

No Timber Framing Required

No Timber Framing Required

Skip the timber battens and plasterboard layers. Faster, cleaner installations.

No Timber Framing Required

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.

Access Panel Compatible

Access Panel Compatible

Easily create removable panels for valve and fitting access.

Access Panel Compatible

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.
