Stormhut™ Science
Stormhut™ Science
Engineered for British Weather
Built to handle rain, wind, frost, snow and UV.
Stormhut WeatherGuard™ was developed to solve a simple problem:
standard shed felt isn’t built for British weather.
Most shed felts are produced to meet a price point, offered in multiple grades, and designed for mild conditions. In real UK gardens, that often leads to cracking, lifting, leaks and premature failure.
Stormhut™ takes a different approach.

The Problem with Standard Shed Felt
Traditional shed felt commonly fails because it:
- Absorbs moisture instead of shedding it
- Becomes brittle during cold weather
- Softens and shifts in heat
- Tears around fixings over time
- Is sold in confusing grades with unclear performance differences
- These weaknesses can lead to water ingress, timber damage and repeated replacement.
Stormhut WeatherGuard™ was engineered to remove these failure points.
The Stormhut Approach
One heavy-duty shed felt. Everything you need. Done right.
Stormhut believes choosing shed felt should be simple and dependable.
That’s why WeatherGuard™ is produced to one uncompromising specification — removing guesswork and delivering consistent performance across every roll.
No grades.
No confusion.
No compromise.

WeatherGuard™ 4-Layer Protection System
At the heart of Stormhut Science is the WeatherGuard™ 4-Layer / 4-Season Protection System, designed to deliver strength, stability and long-term protection.
UV Protective Top Layer
A mineral granule finish helps protect against UV exposure and surface weathering, extending the lifespan of the felt.
Waterproof Membrane
A bitumen-saturated membrane provides dependable waterproof protection when correctly installed.
Reinforced Fibre Core
A reinforced glass fibre carrier improves strength, dimensional stability and resistance to tearing.
Bondable Backing Layer
A sanded, bituminous underside designed for secure adhesion, helping keep the felt stable on the roof surface.
Together, these layers form a balanced, heavy-duty roofing system built for real conditions.
Engineered for British & Northern Climates
WeatherGuard™ was developed specifically for the UK and Northern European climate — where roofing materials must withstand frequent rain, strong winds, frost cycles and UV exposure.
Designed for dependable performance across all seasons:
✔ Wind
✔ Rain
✔ Frost
✔ Snow
✔ UV
This is shed felt engineered for real weather, not idealised conditions.
Designed by Building Materials Specialists
Stormhut™ was launched by building materials experts with a focus on durability, material performance and long-term reliability.
Every design decision behind WeatherGuard™ is intended to reduce common failure points and improve performance over time — not to cut costs or inflate specifications. Striking a balance between non-negotaible performance and price point.
