																	We can advise on how you might achieve the required standard. 
																	Obviously improving the individual u factors in the calculation will improve the overall thermal performance. 
																	Ft 451 with clear insulated glass 60. 
																	This is different than r value that would be used to determine the energy efficiency of just the window pane thus a window with a u value of 1 is more energy efficient than an window with a u value of 5. 
															
													
									
	
		
	
																	Our u value calculator is a whole window calculator designed to calculate an accurate u value of windows and doors. 
																	U values are used to determine the insulating efficiency of the window and all of its components. 
																	U factor is the rate at which a window door or skylight conducts non solar heat flow. 
																	It s usually expressed in units of btu hr ft2 of.
