The national average cost to replace a window in the US is $1,047 installed, based on data from more than one million completed homeowner projects tracked by Modernize.

Windows and doors account for 3.7% of the total cost to build a new single-family home, or about $15,990 on a home costing the 2024 national average of $428,215 to construct, according to the National Association of Home Builders.

A tilt and turn window combines two distinct opening modes in a single frame: a tilt position that vents from the top like an awning window, and a turn position that swings fully inward like a casement.

RC1 and RC2 burglary-resistance hardware is confirmed and documented for PAVA and PIXEL tilt and turn windows and for HORIZON, OKNOPLAST's uPVC lift and slide patio door - but not for every product in the US catalog.

PAVA and PIXEL support round, trapezoidal, triangular, and arched window configurations within the same profile families as their standard rectangular units, with published dimension limits, angle calculations, and radius constraints - data that competing manufacturers publishing custom shape windows generally do not disclose at this level of detail.

Bifold doors transform a wall into a wide, open connection to the outdoors, letting a kitchen flow onto a patio or a living room expand into the backyard. With home design increasingly focused on entertaining, creating that seamless transition has become a key architectural goal.

Did you know that inefficient windows can account for up to 25–30% of residential heating and cooling costs? This isn't a made-up number. It comes from the U.S. Department of Energy. The glass itself often silently drains your home's energy, especially if you're still living with single-pane or outdated double-pane units. When window glass isn't built to insulate or manage condensation, your HVAC system works overtime. That means higher bills, more drafts, and less control over your indoor environment. That’s why we’ve put together this short checklist to assess the condition of your windows.

Do most of your U.S. projects start with familiar window styles like double-hung, sliding or casement? The European Tilt & Turn system offers a higher-performance alternative with a different operating logic. It uses the same basic parts of a window - frame, sash, glazing, hardware and seals - but makes them work together in a different way. Let’s look at what changes.
