When we were choosing windows for a new house, we thought for a long time what to choose – ordinary windows with one sash or windows with double slider. In the end, we decided on the second option, and we did not regret it. We bought our double slider window here with a good discount, check https://windowtechcanada.ca/single-double-slider-windows/ . The double slider windows look very modern and complement the interior of our house. I recommend checking out such models at WindowTech, they have a great selection and good prices.
