Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces.
													
																	Attic insulation r value map. 
									
	
		
	
																	Recommended home insulation r values. 
																	The higher the insulation r value the greater the insulating power. 
																	The higher the r value the better the thermal performance of the insulation. 
																	R value refers to the insulation s ability to resist heat flow. 
															
													
									
	
		
	
																	How do you figure out r value. 
																	The higher r value the better insulation performance. 
																	R value requirements are different based on your location. 
																	Insulation level are specified by r value. 
															
													
									
	
		
	
																	In particularly cold climates you might go up to r 60. 
																	Insulation is identified and labeled by r value. 
																	Installing more insulation in your home increases the r value and the resistance to heat flow. 
																	Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. 
															
													
									
	
		
	
																	The r value or r value is a measure of thermal resistance ability to resit heat traveling through it used in the building and construction industry. 
																	Install insulation with the proper r value. 
																	You ll see insulation r values indicated on product packaging and often on the product itself. 
																	R stands for resistance to heat flow. 
															
													
									
	
		
	
																	The greater the r value the greater the insulating performance. 
																	When calculating the r value of a multilayered installation add the r values of the individual layers. 
																	R value is a measure of insulation s ability to resist heat traveling through it. 
																	Your home s r value score will guide you toward the type of insulation you need. 
															
													
									
	
		
	
																	The amount and r value of your attic floor insulation depends on your geographical location zone. 
																	Colder climates will typically require a higher r value for even greater thermal.
