While thermal data can be found<br /> in many books, hygric data are sparse and hard to come by.<br /> &lt;/P&gt;<br /> &lt;P&gt;<br /> A collection of design values for [[Details:BasicMaterialData | heat conductivity]]<br /> (including the effect of practical moisture content) and<br /> [[Details:BasicMaterialData | diffusion resistance factors]]<br /> is listed in German standard DIN 4108-4<br /> and numerous textbooks on building physics. The new DIN EN 12524 lists thermal as well<br /> as basic hygric design values for building materials.<br /> &lt;/P&gt;<br /> &lt;P&gt;<br /> An extensive list of &quot;NIST Heat Transmission Properties of Insulating and Building<br /> Materials&quot; is available on-line at [http://srdata.nist.gov/insulation].<br /> &lt;/P&gt;<br /> &lt;P&gt;<br /> [[Details:MoistureStorageFunction | Moisture storage functions]] and<br /> [[Details:LiquidTransportCoefficients | liquid transport coefficients]] may<br /> be estimated from the<br /> standard parameters<br /> [[Details:MoistureStorageFunction | w&lt;small&gt;f&lt;/small&gt;, w&lt;small&gt;80&lt;/small&gt;]] and the<br /> [[Details:LiquidTransportCoefficients | A-value]] which may<br /> also be found in some textbooks (at least for selected materials) and data sheets or<br /> can be measured relatively easily.<br /> &lt;/P&gt;<br /> &lt;P&gt;<br /> Occasionally, some data may be found scattered through the specialised literature,<br /> but there is no systematic way to retrieve them.<br /> &lt;/P&gt;<br /> &lt;P&gt;<br /> Sometimes the manufacturer may be able to provide material data. Some laboratories<br /> (including IBP) can measure the required data if samples are provided.<br /> &lt;/P&gt;</div>
