The Science Behind Protection

Why Wet Homes Don't Burn

90% of homes lost to wildfire ignite not from direct flame — but from wind-borne embers that arrive minutes before the fire front. Drench is built around this fact.

of homes lost
Ignite from embers, not flames
Wind-borne embers land minutes before the fire front arrives — collecting in gutters, entering vents, and igniting dry surfaces. A wet surface won't ignite.
7.5mi
speed-aware activation
Activates based on fire speed
Drench tracks fire speed and direction in real time. A fast-moving fire (2.5+ mph toward your home) triggers activation at 7.5 miles. A slower fire activates at 5 miles. Either way, you're protected before flames arrive.

Foam beats water alone
Class A firefighting foam lowers water's surface tension so it penetrates burning material at depth. It extinguishes embers, prevents re-ignition, and reflects radiant heat.

How Drench Works

Your Home Defends Itself

When evacuation orders come, your priority is getting out safely. Drench keeps working after you leave.

01
Detection at 15 miles
Drench begins tracking the fire's position every minute, pulling from live CAL FIRE, NIFC, and satellite data feeds.
02
Speed-aware activation
Drench tracks the fire's speed and direction. A fast-moving fire (2.5+ mph) triggers activation at 7.5 miles — a slower one at 5 miles. Your system activates automatically and notifies you via the Drench app.
03
Full structure saturation
Roof and eave sprinklers cycle through zones, drenching every surface — plus 30 feet of property on all sides — with water and Class A foam.
04
Off-grid backup if the grid fails
If utility power or water pressure fails, Drench instantly switches to its own battery bank and dedicated water tank — no gaps in protection.

The Drench Difference

Built for When Everything Else Fails

Truly Off-Grid
Solar panels, LiFePO4 batteries, and a dedicated water tank mean Drench operates independently of the utility grid — even when power and water fail simultaneously.
Class A Foam Standard
Every Drench system includes Class A firefighting foam as standard — not an add-on. The same formula used by professional wildland fire crews since the 1980s.
Starlink Connected
Drench communicates via Starlink satellite — not local cell towers that go down in fire events. Your system stays reachable and you stay informed, no matter what.
Live Fire Intelligence
Real-time data from NIFC, CAL FIRE, and GOES-18 satellite pixels. Fires tracked every 60 seconds within 15 miles — not hourly updates from a regional feed.
Custom-Engineered Per Property
Every system is hydraulically designed for your specific property — terrain, elevation change, structure size, and water source — not a one-size kit.
WUI Contractor Partnerships
Drench partners with licensed WUI contractors to deliver complete wildfire defense — active sprinkler protection plus structural hardening, installed by trusted local professionals.

The Foam Advantage

5×
More Effective Than Water Alone

Every Drench system delivers Class A biodegradable firefighting foam as standard. The same formula professional wildland fire crews have used since the 1980s.

  • Lowers water's surface tension so it penetrates burning material at depth
  • Extinguishes embers on contact and prevents re-ignition
  • Reflects radiant heat during the most dangerous phase of a fire event
  • Non-toxic, biodegradable, and completely safe for people, animals, and the environment
  • Included as standard — not an upgrade or add-on
