Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
The capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power.
- ‘You should consider the several forms of insulation available, their R-values, and the thickness needed.’
- ‘Manufacturers usually represent the energy efficiency of windows in terms of their U-values (conductance of heat) or their R-values (resistance to heat flow).’
- ‘Both products offer similar R-values to other fibrous insulation types (about R - 3.5 per inch of thickness.)’
- ‘The R-value is the inverse of the U-value, so the higher the R-value, the more the window resists heat flow.’
- ‘For walls, this may mean looking at ways to reduce thermal bridging or increase insulation R-values.’
- ‘When it comes to energy efficiency and insulation, the key issue is R-value cost per square foot.’
- ‘This is done by taking the R-value you would like to achieve and dividing it by the R-value per inch of the insulation material you'd like to use.’
- ‘The next step is to compare the R-value of your insulation with the recommended R-values for your house and your type of space heating.’
- ‘Also note that the R-value only refers to heat transfer per unit time and does not take into account the flywheel effect of concrete's thermal mass.’
- ‘For the best energy efficiency, select the proper R-value for your region, and insulate ceilings, walls and floors well.’
- ‘So, where R-values rate how much heat loss the material resists from passing through it, U-values rate how much heat the component allows to pass through it.’
- ‘Check with your State Energy Commission, local power company, or local home center for the optimum R-value in your region.’
- ‘Discuss the house plans with your builder, and make sure each of these spaces is insulated to the recommended R-values.’
- ‘It's more efficient to use insulation with higher R-values in the attic and in rooms with cathedral ceilings than in wood frame walls and basements or crawl spaces with walls.’
- ‘Insulation loses its R-value as it takes on moisture.’
- ‘The cavity created by the added framing should be thick enough for the desired insulation R-value.’
- ‘Thermal characteristics mean the R-value of the material.’
- ‘Don't forget that R-values are determined by material type, thickness, and installed weight per square foot, not by thickness alone.’
- ‘Water dampens and compresses wall and attic insulation, lowering R-values and increasing heating costs.’
- ‘Thicker insulation does not necessarily mean higher R-value.’
