Following on from last week's blog, we made repairs to the timbers at Holton St Mary, and we are now in the process of installing sheep's wool and savolit board for insulation. Sheep's wool is great as an insulator as it is a high density material. It is also one of the only fibres that has a naturally high nitrogen content, which means that it is flame resistant and self-extinguishing. Sheep's wool is also able to absorb and release excess moisture. It also good for sound proofing. It is a great natural and sustainable insulator, 

The savolit boards that we are using are natural panels made of wood fibres that are compacted and used as an alternative to plasterboard. They have a high resistance to moisture and frost, which as we discussed in a previous blog about damp problems in period properties, makes them a fantastic product to use in these buildings. They are also strong, and able to flex with the building, and like the sheep's wool, they have a low environmental impact.
