As the greenhouse interior temperature rises above approximately 72°F (22°C), the paraffin expands and pushes a piston outward, which opens the window. As the temperature drops, the paraffin contracts and the window closes under its own weight. The cycle repeats automatically throughout the day with no user intervention or electricity required.\u003c\/p\u003e\n\n\u003ch3\u003eRelated Accessories\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct\u003c\/th\u003e\n\u003cth\u003ePurpose\u003c\/th\u003e\n\u003cth\u003ePrice\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003ca href=\"\/products\/riga-automatic-window-opener\"\u003eRiga Automatic Window Opener\u003c\/a\u003e\u003c\/td\u003e\n\u003ctd\u003eReplacement or additional opener for an existing roof window\u003c\/td\u003e\n\u003ctd\u003e$119\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003ca href=\"\/products\/riga-piston-replacement-piston\"\u003eRiga Replacement Piston\u003c\/a\u003e\u003c\/td\u003e\n\u003ctd\u003eReplacement piston for a failed automatic opener\u003c\/td\u003e\n\u003ctd\u003e$44\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003ca href=\"\/products\/riga-roof-window-wind-restraint-system\"\u003eWind Restraint System\u003c\/a\u003e\u003c\/td\u003e\n\u003ctd\u003eStainless steel cables to limit window opening in high winds (IIs, IIIs, III)\u003c\/td\u003e\n\u003ctd\u003e$32.99\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this window come with an automatic opener?\u003c\/strong\u003e\u003cbr\u003eYes — each Riga Window includes one automatic wax-cylinder opener.
