Bifold doors have become a massive trend in British home extensions, but they often make rooms uncomfortably hot. To enjoy the view without the greenhouse effect, I recommend the "Super Cool" solar film range from Tintfit: https://www.tintfit.com/shop/uv-protection It rejects a huge amount of solar energy while remaining light enough not to darken the room. It allows you to keep the doors closed on sunny days without the room becoming stiflingly hot.
