																	3 4 vs 5 16 hardwood flooring. 
									
	
		
	
																	The insulation value of 3 4 is nearly double the 5 16. 
																	If you re shopping for solid hardwood floors you ll find three thicknesses of boards. 
																	Classic narrow strip floors of 2 1 4 and 3 1 4 are as popular today as they were when your grandparents built their home. 
																	A thin board is more likely to warp or split. 
															
													
									
	
		
	
																	While narrow floor boards can be more appropriate for a more refined wood essence and appearance. 
																	I have always bought 3 4 flooring for my projects and never really shopped for a price. 
																	My question is whats the difference in 5 16 and 3 4 flooring. 
																	If you want an authentic rustic look or an upscale modern feel even wider planks will elevate the overall value and aesthetic of your room. 
															
													
									
	
		
	
																	Wider boards offer a larger surface which is perfect for floors with more character and knots. 
																	Recently we ve seen growing interest for board widths of 4 5 or even 7 inches wide which have become very popular with contemporary style decor. 
																	The hardwood layer on top ranges in thickness from 6 millimeters to 4 millimeters. 
																	When looking for new hardwood floors a multitude of style options are available. 
															
													
									
	
		
	
																	The thicker the board the more it costs but the longer it will last. 
																	When it s time to refinish the floor you aren t going to have much left with 5 16. 
																	In the last 3 5 years 5 boards have become the new wide standard. 
																	5 8 inch 15 88 mm 3 4 inch 19 mm 7 8 inch 22 23 mm the best and most common thickness of solid hardwood is 3 4 inch 19 mm.
