R values of selected suspended ceiling products designs building energy audits.
													
																	Drop ceiling r value. 
									
	
		
	
																	When determining how much insulation you need don t guesstimate calculate. 
																	For an insulated space it does not mater so much if you miss the r value of an r30 insulated ceiling by r1 its only a 3 error in heat loss. 
																	In warm regions r 30 insulation is often sufficient for ceilings while colder climates might require insulation values up to r 49. 
																	R value measures how well certain building insulation materials can resist heat. 
															
													
									
	
		
	
																	The higher the r value the greater the insulation performance. 
																	Know exactly how much you need with our project calculators. 
																	R value is say 2 0 this will result in a 50 error in the heat loss.
