When you're purchasing window frames, there are a few things to consider. First, you'll need to decide what type of frame you want: sash or casement. Sash frames are the most common and are made out of two pieces of wood that hinge together at the bottom. Casement frames are made out of one piece of wood and open and close like a door.

Second, you'll need to know more about what material you want your frame made out of. You have a few options: wood, metal, or plastic. Wood is the most traditional option and has a natural look and feel. Metal is more contemporary and has a sleek look. Plastic is the most affordable option and can be shaped into any shape you want.

Finally, you'll need to decide how much money you want to spend on your frame. You can get a basic wooden frame for under $100, but metal and plastic frames tend to cost more.

When you are shopping for window frames, be sure to consider the cost. Window frames can be expensive, and you may want to factor this cost into your decision-making process.

There are a few factors that will affect the cost of a window frame. The size of the frame will determine how much it costs to buy, as will the type of frame. Wooden frames are usually cheaper than aluminum or steel frames, and they are also less likely to break. However, wooden frames can be more difficult to clean and they may not hold up well in cold weather.

The material used in a window frame also affects its price. PVC frames are cheaper than wooden frames but they may not last as long. Aluminium frames are more expensive than PVC or wood but they are stronger and more resistant to weather conditions.
