The u value calculator covers all the main ways of building walls flat roofs pitched roofs and floors using kingspan insulation products.

Concrete floor u value calculator.

A reasonable r value for a normal concrete slab can be estimated using an r value the thermal resistance per inch of thickness between 0 1 and 0 2 and multiplying it times the slab thickness. Reference table for u values u value is the coefficient of transmission i e the transmission of heat through the materials which compose the building s envelope or outer shell. In particular i use the u value calculator within the member area because i can quickly produce u value calculations for inclusion within my projects specifications robin bradbury bradbury design 100 000 members and counting. Calculating the inverse of that 1 r would give you a u factor in the range of 1 67 to 0 83.

For a 6 inch slab r value would be between 0 6 and 1 2. This simple u value calculator can help you quickly check your designs or plans to see if they are likely to achieve bs en iso 6946 2017 compliance. This easy to use interactive tool is designed to help calculate the thermal performance of varying combinations of insulation and blocks including aircrete and aggregate blocks.
