Natural & Breathable Materials

The most effective way to manage your heating costs while allowing the building to breath.

The Oldbuilders Company is well known for our reputation as a specialist in breathable and natural insulation systems that function efficiently and effectively in the very different environment of an old building or the requirements of a natural build. Efficient insulation is not just about piling on thick insulation with no regard to its effects on other aspects of the building. Managing moisture, condensation, ventilation and heating is as important as the quantity and type of insulation - and that's why conservation experts recommend natural breathable materials, such as Hemp wool, Hemp-Lime, Sheep's wool & silicate Boards and insulated lime plasters, the right materials result in more effective method to insulate your period home.  Using an inappropriate type of system will cause far more problems than it solves, condensation and damp & mouldy unhealthy buildings are the results.

Importance of breathability  -  Donít dry-line, Lime-Line or hemp-Lime   -   Why use Lime ?
