Lower Energy Bills. Healthier Home. No More Damp.
Your walls might be costing you hundreds every year. Active Vent uses the power of wind to keep walls dry and insulation working - so you stay warm and save money.
How Active Vent Keeps Your Walls Dry
Simple, effective, and powered by nature. Active Vent harnesses wind energy to actively remove moisture from your cavity walls - keeping insulation dry and your energy bills low
Why Are Your Energy Bills So High Even Though You Have Insulation?
You're not imagining it. Your heating bills shouldn't be this expensive - especially if your home has cavity wall insulation. The problem? Your insulation might be wet, and wet insulation doesn't work.
The Hidden Energy Killer:
Scientific research has uncovered something shocking: moisture in cavity walls can reduce insulation effectiveness by up to 186%. That means your insulation isn't just working poorly - it's actually making your energy bills worse than if you had no insulation at all.

How Does Moisture Get In?
- Rain seeping through brickwork
- Humidity from temperature differences
- Condensation (interstitial damp - moisture trapped between wall layers)
- Traditional vents that can't remove it
What Happens When Walls Stay Wet?
- Your heating costs skyrocket
- Rooms feel cold no matter how high you turn the heat
- Mold and musty smells appear
- Your home's value decreases
The Real Cost:
If heating and cooling accounts for nearly 50% of your yearly energy costs (according to the U.S. Department of Energy), and wet insulation is making your system work 2-3x harder... you could be paying hundreds of pounds extra every year without realizing it.
That's money literally evaporating out of your walls. 💸
