Webb18 mars 2007 · Rex Ingram, UHMA chairman, organised the testing at BSRIA. He explains, ‘The tests were devised to clear up one of the last myths about underfloor heating. BS EN 1264 advises a maximum thermal resistance of just 1.5 Tog for any floor covering laid upon a heated floor. WebbAs a high performance acoustic underlay, it is suitable for use with solid wood, engineered wood and laminate flooring. It is easy to fit and the fact that it has a low thermal resistance (TOG rating: 0.9), makes it also ideal for use with underfloor heating systems. It comes with a built in DPM therefore suitable to use on concrete sub floors. easter eggs in a basket clipartWebbThe Thermal Resistor block represents a temperature-dependent resistor. When the temperature at the thermal port is T, the resistance is R = R 0 ( 1 + α ( T − T 0)) where: R0 is the nominal resistance at the reference temperature T0. α is the temperature coefficient. The following equation describes the thermal behavior of the block: easter eggs images free
