RUF Bark Overnight Bricks Sample Pack

Made from:

RUF Bark Overnight Bricks are made from clean, dried bark. Bark is designed by nature not to burn, but when it’s dried to below 10% moisture content and compressed into dense blocks, it makes an excellent fuel with high calorific value. An RUF Bark Overnight Bricks Sample Pack is one 12kg pack.

Burning characteristics:

RUF Bark Overnight Bricks burn slowly and with a low heat production. They are designed for keeping stoves in overnight safely. Like peat, bark contains more silica than heartwood, so it does leave more ash. However, it is the accumulation of ash that helps hold the heat overnight.

Bark is an excellent environmentally-friendly alternative to peat, with very similar burning characteristics.

Perfect for:

These dense bricks are best for keeping fires in for long periods of time, rather than producing lots of heat. Perfect for keeping your stove in overnight, they are also great for extending the life of your fire through the day and can help slow down a fire that’s prone to burning fast. Try combining them with Hotties, Blazers or Hotmax to give a good balance of heat and long burn time.

RUF Bark Overnight Bricks come in a plastic outer, which is widely recyclable. Please check with your local authority for recycling facilities.

The briquetting industry uses plastic to wrap wood briquettes in order to ensure they stay dry, as damp briquettes break up and are unsuitable for burning. The environmental impact of our products is important to us, so we are constantly working with our suppliers to improve the sustainability of their packaging by using cardboard in place of plastic wherever possible.
