The Impact.

The manufacturing and construction of buildings creates 10% of all global greenhouse gas emissions.

The impact hero

That’s a lot. But reducing this number is possible, if customers and designers can be persuaded to choose products and building systems that have less impact.

So where can we start? The first step is to cut through the BS and get to the facts.

And with us, you’ll get the facts. Every time.

You see, greenwashing is not our thing. We don’t shout about being carbon neutral or sustainable. Because these terms aren’t honest or useful.

What we stand for

  • Brimstone is not about business as usual.
  • It’s about creating great products from local wood.
  • It’s about reviving our local woodlands.
  • Reducing the impact of building.
  • And providing honest, straightforward information.
  • Always.


A lot of the environmental impact of building products can be measured and calculated. An Environmental Product Declaration is the official way to present these numbers. But, it’s not light reading.

From harvesting a tree to finally disposing of Brimstone cladding at the end of its useful life (Modules A1 – C4) 1 M2 of 20 x 145mm Brimstone cladding creates 8 Kg of CO2e(1)

To put that into context: 1m2 of brick-faced Precast Concrete Cladding creates 122 kgC02e(2)

Three steps to driving change

Greenwashing is easy. Driving real change takes effort and action. It’s about small steps and incremental nudges. Here’s how we’re making change happen.


Reducing impact

Cutting transport
We attempt to buy, manufacture and sell Brimstone within a 100 mile radius of our factory.

Using cleaner energy
We’re moving over to renewables as quickly as we can. We aim to have the modification plant running on 100% renewable energy by the end of 2022.

Woodland management
We’re pushing our suppliers to manage their woodlands for the long term.

Cutting waste
We’re always looking for ways to use more of the tree and waste less.


Having a positive impact

Using local wood
Buying local wood benefits local woodland. 80% of income for woodland owners comes from selling timber. This income pays for management and conservation, which boosts biodiversity and resilience.

1% Woodland tax
We pledge to donate 1% of our turnover to organisations that are working to improve the state of our local woodlands.

Locking up carbon for the long term
Brimstone cladding and decking will store 18 kg Co2e per M2 for at least 30 years.


Changing the system

Forging partnerships
We work with organisations including Grown in Britain, Sylva Foundation and the Future Trees Trust to reimagine the future of our woodlands.

Leading by example
Brimstone is evidence that the building industry can use more home-grown wood without compromising on product cost or quality.
