Why Dragon Vents Roof Vents Beat Cheap Rubber-Boot Systems
Not all roof vents are built to last. Many builders still fit imported rubber-boot vent kits because they’re cheap up front — but that “saving” often leads to leaks, call-backs, and ceiling damage later. Dragon Vents Australia (DVA) designs and manufactures vents for real Australian conditions. Here’s why our DV-Series Hi-Flow Roof Vents outperform the generic rubber-boot alternatives.
Built for Bushfire and Weather Protection
Rubber boots rely on thin metal cowls and glued rubber collars that crack and fail under UV and heat. Once that happens, water and embers find their way into the roof cavity.
- BAL 12.5–40 rated and CSIRO-tested for ember resistance.
- Constructed from Colorbond steel or 304 stainless steel — no plastic, no rubber.
- Sealed with 1.99 mm perforations that block embers and vermin without restricting airflow.
💧 Triple-Sealed, Fully Waterproof Design
The DV-350LP Hi-Flow Roof Vent is completely waterproof and weather-sealed. Where cheap vents depend on one layer of silicone, ours feature a three-stage seal to stop leaks permanently.
- Sealed 150 mm Spigot Plate ( installed first) – The mounting plate beneath the vent is fully sealed on all sides, preventing water entry even in storms.
- Protective Shroud (Fitted and sealed on top of Mounting spigot plate) – The full metal scroud shields the roof penetration. Flashing fingers are undersealed with silicone for a permanent weather barrier.
- Extended Spigot Protection – The spigot protrudes 30 mm through the mounting plate in the vent , diverting any water that happens to pass the top flashing — eliminating leak risk.

No rubber seals. No mesh inserts. Just solid metal construction that keeps your roof dry for decades.
🌬️ High-Flow, Low-Noise Performance
Rubber-boot cowls restrict airflow by up to 40%. DVA’s patented Hi-Flow design delivers tested performance up to 1030 m³/h, so rangehoods and exhaust fans run quieter and last longer.
- Better smoke and steam extraction.
- Lower noise and fan load.
- Meets NCC 2025 air-exchange standards.
🧱Engineered for Structural Integrity
Generic imports use flexible rubber collars that crack as roofs expand or shift. DV350LP is used on Corrogated roof angles 12degrees and greater. (Average angle is 25 degrees ) There’s no movement, tearing, or leak path — and the low-profile shape also fits neatly under solar panels for a clean, modern look.
🪲 Maintenance-Free and Vermin-Proof
Rubber vents collect grease, dust, and bugs that clog outlets and stain roofs. DVA vents are fully enclosed, preventing insect entry, corrosion, and roof staining. No maintenance. No mess.
✅ Built for Compliance and Reliability
Every DVA vent is engineered to meet AS3959 (Bushfire Attack Level) and AS/NZS 3666 (Airflow & Hygiene). Builders across Western Australia are replacing imported rubber-boot kits with DVA’s Australian-made systems that simply last.
🏡 The Smart Choice
A cheap rubber boot can lead to hundreds of dollars in repairs and endless warranty headaches. The DV-350LP Hi-Flow Roof Vent is a once-off installation that protects your roof, improves airflow, and looks great doing it.
Choose a Hi-Flow vent system engineered for Australian homes — not a short-term import.
