The final advantage of engineered wood flooring over solid oak flooring that I am gong to mention is how an engineered oak floor is more environmentally friendly. The plywood that is used is made up of fast growing softwoods which are plentiful and this is what the under side of our engineered wood flooring is constructed of. This means that far less of our valued oak, which has taken hundreds of years to grow, is used resulting in a much more environmentally friendly flooring.
Hardwood flooring is often a generic term that could apply to any type of wood flooring. Hardwood trees (oak, maple, cherry, walnut, elm, chestnut) are generally trees that had leaves which fall off in the winter. Softwood trees (pine, fir) have needles that may stay on all year and usually they produce cones. Hardwoods are usually more dense and more durable than softwoods. Of course, there are exceptions to these generalities. In our product line the hardwoods cost more than the softwoods.
With reclaimed material waste factor is a huge variable. How much effort does the manufacturer take to give you a 100% usable product? Poorly milled with very little defecting and culling done on a solid wood floor that costs $6/sf and has a 15% waste factor actually costs more than a similar product that is milled better costing $7/sf with a 2% waste factor. That extra wastes costs more in shipping and labor to defect. This is one of the hardest things to demonstrate to a customer that the face value costs doesn`t necessarily represent the actual raw material cost unless one is truly comparing identical quality and specified products.
So let`s start off this article with talking about the number 1 reason our engineered oak floors have the upper hand over solid oak floors, this being it`s stability. A quality engineered board will be made up of around 10 layers of multi laminated birch ply wood. These layers are stuck in opposite directions with a moisture resistant adhesive and this gives the floor an immense amount of stability. We have been asked before by customers who have researched the market how strong the adhesive is as they have heard of stories of engineered wood flooring de-laminating.
Raw sheathing comes in 4`x8` sheets, most often installed as 3/4" thick plywood panels. This type of sheathing is adequate for spanning joist work spaced up to 24" apart. The sheathing is lain with the joints staggered in such a matter, that no two edge joints line up with adjoining sheets. It is very easy to install, requiring the least amount of labour. The sheets are fastened with either 1-1/2" flooring screws, or 2-1/2" nails, spaced about 8" apart. Although not required, it is a good idea to provide backers or supports under the joints, between sheets which run perpendicular to the framed floor assembly.
Of all, the most commonly installed flooring system are framed floors. They consist of dimensioned lumber, bearing on exterior and interior load bearing walls or beams called "floor joists". Generally the floor joists are installed, spaced 16" apart. Installing rim and trimmer joists, to which the floor joists are nailed, finishes the perimeter. Bracing, usually in the form of bridging, but often installed as strapping, prevents the joists from turning in place. One other method used to prevent this type of turning is to glue the sub-flooring to the joists, as the sub-floor is placed.
