Description
SENTINEL T-JOINT PATCHES are pieces of circular membrane composed of thermoplastic polyvinyl chloride (PVC) and a fiberglass reinforcement.
QUANTITY PER PACKAGING: 100 PC
Material Use:
SENTINEL T-JOINT PATCHES are pre-formed circular patches made from thermoplastic polyvinyl chloride (PVC) membrane with fibreglass reinforcement. They are specifically designed for use in roofing applications to reinforce and seal T-joints in SENTINEL PVC membrane systems. These patches ensure watertight integrity at membrane intersections and can also be used as general reinforcement in other vulnerable areas of the roof system.
System Components:
SENTINEL T-JOINT PATCHES are part of the SENTINEL PVC roofing system and are used in conjunction with SENTINEL PVC membranes. They are not standalone waterproofing materials but serve as accessory components to enhance the performance and durability of the overall membrane system. The patches are compatible with other SENTINEL PVC products and are installed using hot air welding equipment.
Applications:
These patches are used in flat or low-slope roofing systems where SENTINEL PVC membranes are installed. Their primary function is to reinforce T-joints—areas where three membrane sheets intersect—ensuring a continuous, watertight seal. They may also be used in other areas requiring additional reinforcement, such as around penetrations or at membrane terminations.
Application Details:
SENTINEL T-JOINT PATCHES are installed using an electric hot air welder, which fuses the patch to the underlying PVC membrane. The surface must be clean and dry prior to welding to ensure proper adhesion. The patches are 114 mm (4.5 inches) in diameter and 1.5 mm (60 mils) thick. No primer is required for installation, but proper surface preparation and welding technique are critical for performance. The patches are bare-backed and do not include adhesive layers.
Special Notes:
- SENTINEL T-JOINT PATCHES are available in white and grey to match the SENTINEL membrane colors.
- These patches are reinforced with fibreglass, providing added strength and dimensional stability.
- They must be stored in a clean, dry environment, protected from heat and moisture.
- As part of a thermoplastic system, the patches are UV resistant once installed and fully integrated into the SENTINEL membrane system.
- The patches are not designed for use with non-PVC membranes and should only be used with compatible SENTINEL PVC products.
- Each pallet contains 100 patches, and they are intended for professional installation by trained roofing contractors familiar with hot air welding techniques.
This material is a critical accessory in the SENTINEL PVC roofing system, ensuring long-term performance and watertight protection at membrane intersections.
