Installation Note: Choosing the Right Plenum Box Type

When specifying and installing Ventmann Plenum Boxes, the orientation of the HVAC ductwork connection (where the air comes from) dictates the optimal box type for best acoustic and thermal performance.

Key Installation Observation:

  • For "From Above" (Top Entry) Installations: Please select the Acoustic Plenum Box (GTG Series). This type is designed to primarily address and mitigate sound transmission from the ducting system into the occupied space, which is typically the priority for vertical (top) connections.
  • For Lateral (Side Entry) Installations: Please select the "V" Shape Insulated Thermo Box (VTBOX Series). This type is insulated and features the specific "V" shaped air path required for optimal thermal regulation and air delivery when connecting from the side.

Insulated Thermo Boxes for Linear Slot Diffusers – Flat Packed, Easy Assembly, Multiple Sizes

Our insulated Thermo Boxes come flat packed for ease of transit and storage on site.

Easily assembled by folding into shape and securing with a square SQ2 bit using the screws supplied, fixed into the pre-drilled holes.

The boxes come with pre-score knock-outs (125mm, 160mm and 200mm) that can be removed as required.   The ducting spigot (by others) is then fixed to the outside of the box using suitable tech screws and/or sealant.

The VT Thermo Boxes come in three lengths to match the linear diffusers, and three width codes (A,B and C). Please ensure you match the width code on the box with the requirement from the slot diffuser.
