The wool rope is more sympathetic to the environment,” says Kate. “When they use plastic rope, they have to return and cut it out several years later, and there is always the question of how much is actually collected.” We work out the price according to the size of the ‘Sheep but it’s no more expensive for being tailor made for your chimney. For example, if you needed a 14″ square one it would be a bit more than the 13″ square one but not as much as the 12″ x 20″ one.

Those are the three types of insulation, which can be applied in walls, floors and ceilings. There are also some effective wool underlay products in the SilentWool range.A draft stopper for your fireplace can make a noticeable difference to the temperature of a room or even your whole house. We’ve definitely noticed that our living room hasn’t been so cold since we started using a draft stopper within our open fireplace. We have a 60-day return policy, which means you have 60 days after receiving your item to return it. Although fitting a chimney cap will help when it comes to preventing draughts and heat loss, using an additional draught excluder is still often a good idea.

The Chimney Balloon is made from plastic, and is designed to be inflated, using a pump or by blowing into a pipe, to fill the chimney and prevent cold air from coming in and warm air from travelling up and out.The Chimney Sheep® draught excluder works by being a little bit bigger than the flue so it can grip onto the sides and hold itself in place. The amount of overlap doesn’t matter too much as the felt is squashy and can fit into a range of gaps. Reduces your carbon footprint – a Chimney Sheep® makes your heating more efficient, reducing your CO2 output by up to 250kg per year.

If you have a top-sealing damper there should be a chain with a handle located to the side of the firebox. Pulling this lever will open and close the damper. Our robust, durable stone wool products are non-combustible and won’t contribute any significant toxic smoke when exposed to high temperatures, forming a strong fire barrier in residential, commercial and industrial settings. We offer an array of products to suit different chimney shapes and sizes, all of which are easy to cut and install. In addition, our Core Solutions team provide bespoke, tailored insulation integration – and ongoing support to the manufacturers they work with.The Chimney Balloon was started up by an engineer in the 1980s, although many other companies have since set up offering similar products. In 2017, The Chimney Balloon Co. was bought by Chimney Sheep Ltd and although the products they offer are different they now work together. You can also choose to have glass doors fitted to the opening of your traditional fireplace and provide a barrier between the fireplace and the room to help prevent cold drafts. SilentWool Joist is also a very useful product in the armoury of wool sound insulation. It is 10cm wide, 10m long, same stuff as the SilentWool Floor (minus the paper) that is rolled out along a joist and stapled to it before the next layer of timber is laid across it. This significantly reduces sound reverberation through buildings.
