Sliding windows work best for wide, low openings where the sash has to move sideways and stay inside the wall. You get ventilation without a crank swinging over a deck, a walkway, or a narrow side yard. The glass rides a track. It doesn't stick out past the siding when open. A single unit has one sash that slides and one that stays fixed. A double unit lets both sashes move, so you can open either end of the same frame.
Tilt-and-turn windows pay off when you want a small vent you can leave open, and a way to wash the outside pane from inside the room; the hardware is wasted when the sash has no arc to swing through. One handle runs both openings. When closed, the sash pulls into a seal on all four sides. That combination is the benefit. The room has to be able to take the swing, or the second opening never gets used.
Standard window sizes in Canada are planning bands for the opening already in the wall, not a federal chart of frames you can buy off a shelf. Width is written first, then height. A replacement is built to the smallest width and the smallest height of that opening, so a catalogue size fits only when the hole happens to match it.
Soundproofing windows is a sequence, and the first move is to close the path air already uses. A locked sash, a seal that still compresses, and a frame that meets the wall change the room on the first afternoon, before a curtain or a film on the glass does.
Window casing is the moulding on the room side of the opening, and brickmould is the exterior trim that covers the joint between the frame and the cladding. Casing hides the gap where the frame meets drywall. Brickmould finishes the joint you see from the yard. Neither board is the frame, and neither board is the layer that keeps rain out of the wall.
Black windows are a dark finish on a vinyl frame, and that finish absorbs more of the sun than white vinyl on the same wall. The colour is either carried in the vinyl or applied as an exterior laminate. It is not paint, and it does not change the glass.
Basement window replacement means installing a new unit in a style that vents the low opening, sized to the hole already in the foundation, and removing the old frame only when the liner is soft, shifted, or too small. The concrete usually stays. What changes is the sash, the seal, and, when the wood has failed, the liner set inside that concrete.
You find and vet window installers in Calgary by making a short list of firms that will measure the openings, then checking three things before a deposit moves: a prepaid contracting licence when money is taken early, a WCB-Alberta clearance, and whether the City of Calgary even requires a permit for the work you are buying.
An entry door that will not latch or close properly almost always has a latch that no longer meets the strike plate. The slab has dropped on tired hinges, the frame has moved with the house, weatherstripping is holding the door off the jamb, or the hardware was never reset after seasonal movement.
No window eliminates sound. A well-specified assembly lowers the level enough that traffic stops being something you notice and becomes something you have to listen for.
