Width & Length – Plank flooring comes in a variety of widths and lengths. The most common widths are currently in the 5” – 6” range, but wider widths are rapidly becoming more popular. The length of your floor is also important to consider depending on the size of your space. Hardwood flooring comes in mixed lengths because imperfections are cut out of longer planks during production. Rigid Core flooring is built to size and comes in lengths ranging from 36” up to 80+”.

Awesome explanation! When I say heat pump to people, it's amazing how often their eyes glaze over...even though most of them have had refrigerators and air-conditioners their whole lives and have never asked themselves how they work. Same principle! Compressor and expansion valve (and the heat-holding capacity of a phase change; another confusing one for people). thanks for helping educate!
Refinishing can actually take much more time than fully replacing a wood floor. Refinishing is a messy, meticulous process than can take approximately four to five days, during which the floor surface must remain completely untouched. The process requires sanders, edgers, buffers, scrapers, brushes, base coat sealers, topcoat sealers, putty knives and sometimes paint. Replacement, on the other hand, can be done in considerably less time using only lumber, a couple of saws, measuring tape, a flat bar, a chalk line and a nail gun. Hardwood Floor
Generally, hardwood floors need to be buffed every 3–5 years. The process usually takes about one day. Buffing refers to the process of using a stand up floor buffer. The floor is abraded with 180 grit screen on the buffer. This allows for the new coat of finish to mechanically adhere to the floor. This process works with great results as long as the floor hasn't had any waxes or synthetic cleaners. Hardwood Floor

Glue down engineered hardwood, alternatively. If you don't want to nail down the boards, you do have the option of using adhesive to put engineered hardwood in place. It's a good choice, but won't last as long or be as sturdy as nailed down hardwood. The procedure is very similar to the nail-down process. Follow the adhesive manufacturer's instructions for installation and drying times.[11] Hardwood Floor
