What is a Damp Proof Course (DPC) and why does It matter?Updated 2 days ago

A DPC, or Damp Proof Course, is a protective barrier designed to prevent moisture from rising up from the ground into your cabin. It is typically installed between the base and the timber structure, helping to stop damp from reaching and affecting the building.

Its main role is to act as a moisture barrier. Without a DPC, water can be drawn up into the timber through capillary action, which over time can lead to issues such as damp, swelling, and potential decay. By stopping this upward movement of moisture, a DPC helps keep the structure dry and protected.

This also plays an important role in insulation performance. Moisture can reduce the effectiveness of insulation materials and make a space feel colder. By keeping the base of the building dry, a DPC helps the insulation perform as intended, maintaining better thermal efficiency and a more consistent internal temperature throughout the year.

For log cabins in particular, this is especially important. As a natural material, timber can absorb moisture if it is not properly protected. Including a DPC helps safeguard the base of the cabin, supporting both the longevity of the structure and the overall effectiveness of the insulation.

This insulation upgrade is supplied with a DPC as standard, providing added protection against rising moisture and helping to maintain long-term performance.
