Oak windows are ideal for a traditional ambience and are usually used in older buildings and houses. However, they are also a good choice for modern buildings and can give a unique and stylish look. Oak windows are very strong and can protect against wind and weather. Although they can be a bit more expensive than other window frames, they offer a very long life and are usually installed only once.
