Key Advantage
One-piece ductwork — no gluing
Our EPP ductwork is manufactured from a single piece of material — no bonding or gluing involved. Competing products consist of two blocks glued together, and that joint is the weakest point of the entire system.

Construction
Made from a single block of EPP — no seams or joints
Assembled from two blocks bonded with adhesive
Airtightness
100% airtight throughout the entire service life
Joint degrades over time and loses airtightness
Joint
No adhesive = no risk of degradation
Risk of air leakage at the bonded seam
Insulation
Uniform 20 mm thickness around the entire circumference
Uneven insulation at the glued seam
EPP Density
57 kg/m³ — superior noise attenuation and strength
Only 40 kg/m³ — weaker attenuation and lower durability
Technical Specifications
Why choose EPP ductwork?
Expanded Polypropylene (EPP) is the most advanced material for HVAC distribution systems. It combines excellent thermal insulation with mechanical durability.
Outer: 200 mm
Inner: 160 mm
Insulation: 20 mm
One-Piece Construction
No gluing
Moulded from a single block of EPP. No seams, no adhesive, no weak points.

Up to 70% lighter than metal. Reduced shipping and installation costs
Optimised Length
Why 0.75 m instead of the standard 1 m?
We surveyed our customers and discovered that the industry-standard 1-metre duct almost always gets cut on site. We designed ours shorter on purpose.
The 1 m standard creates hidden waste
Our research revealed that virtually every 1 m duct section is cut during installation. Connections to recuperation units, manifolds, and tight routes with frequent elbows mean each piece needs trimming.
20–30 cm of unusable offcuts per piece
Short scraps too small for any practical use were simply thrown away. Customers paid for material that never made it into the system.
0.75 m — the optimal real-world length
The shorter length fits typical installation runs more precisely, so nearly every piece is used in full — with little to no offcut.
