We distribute thermal acoustic and fire protection insulation products and associated materials.

Floor u value.

U value calculator for jablite floor and wall insulation products. U value requirement roof 0 13 w m k. U value requirement windows whole window u value 1 4 w m k. Calculating the inverse of that 1 r would give you a u factor in the range of 1 67 to 0 83.

Use our handy u value calculator for jablite floor and wall insulation products. That is how effective they are at preventing heat from transmitting between the inside and the outside of a building. The elements are commonly assemblies of many layers of components such as those that make up walls floors roofs etc. The quick free and easy way to find out the insulation thickness and the u value you need for your building project.

U values designing buildings wiki share your construction industry knowledge. If veiwing this page on a phone it s best to turn the phone to view in landscape mode r values of flooring materials. The u value calculator covers all the main ways of building walls flat roofs pitched roofs and floors using kingspan insulation products. U values of typical building methods u values overall coefficient of heat transmission indicate the heat flow through materials the higher the figure the higher the heat loss.

U value insulation is an established international company that offers the building industry vast product choice combined with in depth technical expertise. 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. R values of different flooring materials. While the values do vary for each particular material and method of construction the following table gives general figures for some common modes of construction.

R values of different flooring materials. For a 6 inch slab r value would be between 0 6 and 1 2. For example a building with material with an r value of r 11 converts to an u value of 0 09 1 r or 1 11 0 09. The u factor or u value is the overall heat transfer coefficient that describes how well a building element conducts heat or the rate of transfer of heat in watts through one square metre of a structure divided by the difference in temperature across the structure.

The jablite u value calcutator gives instant access to multiple u value calculations for jablite insulation products in wide range of applications. U value requirement floor 0 13 w m k. U value requirement semi glazed doors 1 2 w m k. U value requirement opaque doors 1 0 w m k.

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. These numbers will vary from material to material.
