Here is a comment from a flooring forum that should warn you against thin hardwood floors.
Thin hardwood to cover gap 2 inches.
The width of the gap is determined by the length of the run and the type of wood.
On the other hand if the rooms are large like by a couple thousand square feet a 3 4 gap would most likely be recommended.
Typically the gap is about a 1 2 inch.
They are kiln dried surfaced sanded on 2 sides.
So if you want to wrap a beam that is 3 inches 7 6 cm wide on the sides and 4 inches 10 cm by 8 feet 2 4 m long it will cost about 36.
Typical cabinet fillers range from about 2 inches in width to over 4 inches.
Solid wood needs a bigger gap than engineered wood because it expands and contracts more.
Seam binders prevent carpet edges from fraying vinyl floor seams from curling and creates a smooth transition between different flooring surfaces.
I speak from experience on this.
The larger the room the more space will be.
Whitewood can cost around 6 dollars for plank that is 1 inch 25 mm by 4 inches 10 cm by 8 feet 2 4 m.
The 2 1 2 inch x 72 inch unfinished hardwood seam binder easily covers a seam or gap between two flooring surfaces of equal height.
Measure and mark 1 2 inch out from each wall plus the width of the first board and use a chalk box to snap starter lines.
I installed 3.
1 2 inch 12 7 mm 5 8 inch 15 88 mm however you can find engineered with the top veneer of 3 4 inch 19 mm and even as thick as 33 32 26 16 mm which is just over an inch thick in rare instances.
Most solid hardwood flooring these days is 3 4 inch thick but older flooring planks could be as thin as 5 16 inch half as thick at 3 8 inch or just a bit thinner at 1 2 inch.
Our thin wood sizes are not nominal for example if you order a 6 wide board you will get a board exactly 6 wide or wider.
One between the kitchen and the living room first image and another between the kitchen and the outside door second image.
At their widest the gaps are an inch wide and about a half inch deep at the deepest.
You can stain the wrap any color you like.
I have two half inch gaps in the flooring in my kitchen.
How much of an expansion gap you will need will largely depend on the size of the room.
In smaller rooms such as the typical bedroom you could leave as little as a 3 8 gap.
This type of gap filler is made from solid 3 4 inch hardwood just like the cabinet face frame.
Finding a new hardwood flooring option that matches the width thickness and species of an original hardwood flooring can be quite a puzzle.
This is all solid hardwood sheets not plywood and is never glued.
Start by measuring width.
