Double Groove Joinery Panel

(SFPL-DWP-2005)

Our Double Groove Joinery Panels offer superior interlocking strength and thermal insulation, making them an ideal solution for high-performance walling systems in cold rooms, clean rooms, industrial buildings, and controlled environments. With dual tongue-and-groove joints, these panels ensure precise alignment, structural integrity, and minimal thermal bridging. The design improves load distribution and makes installation both fast and reliable.

These panels are manufactured using high-density Polyurethane Foam (PUF) as the core material, sandwiched between durable PPGI, Stainless Steel, or Aluminium facings, providing excellent mechanical and thermal performance for both interior and exterior applications.

FAQS

Q1. How is a double groove panel better than a single groove panel?
Double groove panels provide enhanced structural strength and a tighter seal, minimizing thermal leakage and improving insulation performance.
Q2. Can these panels be used for ceiling or roof applications?
These are primarily used for walling but can be adapted for ceilings with appropriate support framing.
Q3. Are double groove panels difficult to install?
No. Despite the added groove, installation is straightforward and similar to single groove panels, requiring standard interlocking tools.
Q4. What surface finishes are best for clean room environments?
Stainless Steel or food-grade PPGI facings are recommended for hygienic and corrosion-resistant applications.
