Jointing for Ventilation Ducts – Sealant Bonding
#43 of #DEXR100 will teach you how to properly assemble and inspect ventilation duct connections that make use of a sealant.
Use the embedded 3D viewer below to try it out yourself.
Description
This hands-on lesson walks learners through the steps required to seal two plastic ventilation ducts using a PVC connector and duct sealant. Learners will clean surfaces, identify the correct adhesive,
and complete the assembly in the correct order. Along the way, they will learn why sealant is necessary, when this method is best used in real installations, and how to avoid common sealing mistakes.
Learning Goals
By the end of this lesson, students will be able to:
-
Understand when to use sealant-based jointing
-
Prepare plastic duct surfaces for sealing
-
Assemble a basic plastic pipe joint using a connector
How to use in the classroom
- This lesson works well in a series of explorative VR scenarios immersing students in unknown situations.
- The intended age range is middle school to adult learners.
How it's made - behind the scenes
We decorated the scene with library assets & made custom assets for this level. The platform includes an extensive collection of 3D models that you can use directly. With our Blender add-on, you can also push assets into the Dexr platform and iterate quickly, with instant updates enabled through real-time libraries and asset streaming. Next we added the desired props specifically for this lesson.
Inside the web-based, no-code editor, we built the lesson flow with Events & Actions (for example guiding the learner to pick the right tool, highlighting safety steps, and triggering animations). We layered in TTS narration from a 3D guide, added push guidance panels for clarity, and embedded quick knowledge checks at each stage. Like all Dexr lessons, it runs fully in the browser with no installs required, making it classroom-ready and easy to track learner progress through our LEAP learning framework.
