Thermal Break & Acoustic Sealing Tape V494

Closed Cell Foam Tape for Thermal Break & Acoustic Isolation

Specially formulated closed cell PVC foam sealing tape designed for joist, stud and beam applications. CST V494 helps reduce thermal bridging and sound transmission while providing vibration isolation and reducing the risk of condensation. A pressure-sensitive adhesive on one side allows quick installation, with a durable upper surface for smooth application.

PENTASEAL Multi-Functional Window Sealing Tape

BBA Approved Multi-Functional Window & Door Perimeter Sealing Tape

BBA approved, permanently elastic multi-functional sealing tape providing airtightness, weather protection, vapour control, thermal insulation and acoustic performance in a single window and door perimeter seal. PENTASEAL replaces traditional multi-stage sealing methods with one pre-compressed tape that accommodates ongoing structural movement.

ISO-Flame Kombi 120

Fire-Resistant Expanding Joint Sealing Tape

Pre-compressed, fire-resistant PUR joint sealing tape for high-performance fire protection joints in walls, ceilings and building connections. ISO-FLAME KOMBI F120 provides tested fire resistance up to 120 minutes while remaining permanently elastic to accommodate long-term joint movement.

ISO-CONNECT Vario SD

Humidity-Regulating Window & Door Connection Foil

Humidity-regulating airtight sealing foil for internal and external window and door connections. Its variable Sd value adapts to changing humidity conditions, allowing a single membrane to perform on both sides of the connection while supporting effective drying of the joint.

Multi-Functional Airtight Jointing Tape

High Performance Airtight Jointing Tape for Building Boards & Membranes

High-performance airtight jointing tape for sealing joints and overlaps in building boards, vapour barriers and breather membranes. Suitable for a wide range of substrates including cement particle board, calcium silicate board, plywood, chipboard, PE foil, HDPE, PP and PE fleeces.

EPDM EXT Membrane (Non-Adhesive)

EPDM Waterproofing & Vapour Control Membrane

Durable EPDM waterproofing membrane for façade sealing, damp-proof courses and vapour control applications. Textured on both sides for reliable adhesion and suitable for long-term external building envelope applications.

BRIGi® Foam Structural Thermal Break

High Strength Structural Thermal Break & Insulation Foam

Passivhaus approved, high-strength construction foam combining structural performance with outstanding thermal insulation. Designed to reduce thermal bridging around windows, doors, thresholds, EWI systems and other critical building connections.

Tyvek® Tape HDPE Fleece Sealing Tape

Single Sided Diffusion Open Sealing Tape

Diffusion-open HDPE fleece sealing tape for durable airtight and weathertight sealing of membranes, construction layers and penetrations. Suitable for internal and external applications.

PENTA Tight Variable Sd P (Plasterable)

Premium Variable Sd Airtight Tape suitable for Over Plastering.

High-performance, moisture-adaptive airtight and windtight sealing tape for internal and external building connections. With a variable Sd range of 0.4–20 m, PENTA Tight V. Sd P supports effective moisture management and provides a plasterable surface for window, door and construction joints.
