What is a U-Value and what does it mean for your insulation?Updated 6 hours ago

What is a U-value?

A U-value measures how well a building element, such as a floor or roof, retains heat. It shows how much heat passes through a material and is expressed in W/m²K.

What does a lower or higher U-value mean?

A lower U-value means better insulation and less heat loss, helping to keep your cabin warmer and more energy efficient.

A higher U-value means more heat escapes, making the space harder to keep warm and potentially increasing heating costs.

How does insulation improve U-values?

Adding insulation slows down the transfer of heat through the structure. This reduces heat loss in colder months and helps maintain a more stable internal temperature throughout the year.

What difference does this insulation upgrade make?

This upgrade delivers a significant improvement in thermal performance. A standard Powersheds uninsulated 19mm floor has a U-value of approximately 2.53 W/m²K, which improves to around 0.74 W/m²K when insulated.

Similarly, the roof improves from approximately 3.43 W/m²K down to around 0.67 W/m²K.

This reduction in heat loss helps your cabin retain warmth more efficiently, reducing the need for additional heating and making the space more usable throughout the year.

Why is this important for a log cabin?

Insulating key areas like the floor and roof targets two of the main points where heat is lost. By improving these U-values, your cabin becomes more comfortable, more energy efficient, and better suited for year-round use.
