As a living room where you&#8217;d sit in light clothes in January, a cold winter garden isn&#8217;t meant to be used. But as a pleasant winter outdoor space \u2014 free of snow, wind and rain, with local heat if needed \u2014 it works beautifully. We&#8217;ve seen this ourselves at our clients&#8217; homes over the years.<\/p>\n<h2>Nobody buys a winter garden to live in year-round \u2014 and almost nobody wants to<\/h2>\n<p>The most important thing to understand about a winter garden: <strong>the vast majority of people don&#8217;t want one in order to live there all year round.<\/strong> In our experience, the share of such clients is close to 99%.<\/p>\n<p>What people actually want is <strong>a place to be surrounded by nature without snow, wind and rain<\/strong> \u2014 morning coffee in the light, an evening after work, children playing, a pet in the sun, plants protected. That need is year-round, but it is NOT the same as a heated living room.<\/p>\n<p>This is exactly where our principle comes from: <strong>paying twice as much for an insulated winter garden to cover roughly one percent of extra need makes no sense for most people.<\/strong> A cold winter garden delivers about 99% of the real use at about half the price.<\/p>\n<h2>How a cold winter garden is actually used in winter<\/h2>\n<ul>\n<li><strong>Cooling down after the sauna.<\/strong> One of the winter garden&#8217;s best moments \u2014 see below.<\/li>\n<li><strong>Infrared heater.<\/strong> Warms the person and the surfaces, not the whole volume of air. A warm body + a heater = a comfortable spot to sit even in frost.<\/li>\n<li><strong>Fireplace or Bullerjan stove.<\/strong> We have built fireplace corners into winter gardens, and Bullerjan-type stoves have been installed as well. (We handle the flue and fire safety as part of the build \u2014 this is not a DIY job.)<\/li>\n<li><strong>Morning coffee and winding down in the evening<\/strong> in warm clothes, with a hot drink.<\/li>\n<li><strong>Overwintering plants<\/strong> and, in spring\u2013autumn, full-value extra space.<\/li>\n<\/ul>\n<h2>After the sauna \u2014 the winter garden&#8217;s best winter moment<\/h2>\n<p>When it&#8217;s -10 to -20 \u00b0C outside, you don&#8217;t want to step into the harsh frost or back into the hot kitchen. You want to cool down <strong>calmly, out of the wind, without seeing snow.<\/strong> In our experience and our clients&#8217;, a warm body can sit comfortably in a glazed winter garden for <strong>up to about an hour<\/strong> even in hard frost \u2014 with no extra heating at all, purely thanks to the wind and rain shelter. Add an infrared heater or a fireplace and that time stretches even further.<\/p>\n<h2>Why it works \u2014 simple physics<\/h2>\n<ul>\n<li><strong>It stops the wind.<\/strong> Much of the feeling of cold comes from wind. A glass wall cuts it off.<\/li>\n<li><strong>It keeps precipitation out.<\/strong> No snow, no rain, no damp on your clothes.<\/li>\n<li><strong>It&#8217;s a few degrees warmer than the outside air<\/strong> and the house-side wall radiates a little warmth.<\/li>\n<li><strong>It captures the sun.<\/strong> On a sunny winter day the glass space warms noticeably above the outside air thanks to the greenhouse effect \u2014 even in frost it can be pleasantly warm in the sun and out of the wind, the thermometer on the plus side, often with no extra heating at all.<\/li>\n<\/ul>\n<p>This is how a cold winter garden works as a <strong>pleasant buffer zone between the frost outside and the warmth of the house<\/strong> \u2014 an in-between space that is always warmer than outdoors and sheltered, without having to heat the whole room all year round. A person isn&#8217;t warmed by air temperature but by <strong>radiation and clothing.<\/strong> That&#8217;s why a point heat source and warm clothes are enough, even when the thermometer shows only a few degrees above zero. The same principle as why it&#8217;s warm by a campfire even on a cold evening.<\/p>\n<p><strong>Bonus:<\/strong> because a cold winter garden has natural ventilation (openable glass), it doesn&#8217;t develop the condensation and mould problems typical of a heated space.<\/p>\n<h2>Cool in summer, warm in winter \u2014 how the glass choice plays with the seasons<\/h2>\n<p>The sun is low in winter and high in summer \u2014 and a well-planned winter garden uses this to its advantage. Our typical solution plays along with the seasons:<\/p>\n<ul>\n<li><strong>Roof \u2014 tinted glass.<\/strong> In summer the sun is high and sharp, passing over the roof. Tinted (solar-control) roof glass stops a large share of that heat \u2014 under the glass it&#8217;s shaded and can be <strong>even cooler than out under the open sky in direct sun.<\/strong> This way the winter garden doesn&#8217;t turn into a hot greenhouse in summer.<\/li>\n<li><strong>Sides \u2014 clear glass.<\/strong> In winter the sun is low and shines <strong>in from the sides.<\/strong> Untinted (clear) side glass lets that low winter sun in and warms the space. That&#8217;s why we usually leave the sides clear.<\/li>\n<li><strong>Sides open in summer.<\/strong> In summer the side panels slide fully open \u2014 cross-ventilation carries the heat out, and the greenhouse effect simply doesn&#8217;t build up. The winter garden becomes a shaded, airy outdoor terrace.<\/li>\n<\/ul>\n<p>The same structure, the opposite behaviour: <strong>a sun-warmed buffer zone in winter, a shaded and openable cool corner in summer.<\/strong> Which glass goes where depends on the winter garden&#8217;s orientation and surroundings \u2014 we settle that during the on-site survey.<\/p>\n<h2>Insulated vs uninsulated \u2014 is it worth paying double?<\/h2>\n<table>\n<thead>\n<tr>\n<th><\/th>\n<th>Uninsulated (cold)<\/th>\n<th>Insulated<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Winter use<\/td>\n<td>Yes \u2014 as an outdoor space, with local heat if needed<\/td>\n<td>Yes \u2014 as a living room<\/td>\n<\/tr>\n<tr>\n<td>Year-round living<\/td>\n<td>No<\/td>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<td>Natural ventilation<\/td>\n<td>Yes<\/td>\n<td>No (needs a device)<\/td>\n<\/tr>\n<tr>\n<td>Price<\/td>\n<td>Base level<\/td>\n<td>~2\u00d7 higher<\/td>\n<\/tr>\n<tr>\n<td>Who it&#8217;s for<\/td>\n<td>The vast majority<\/td>\n<td>The ~1% who need permanent living space<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>If you don&#8217;t actually plan to <strong>live<\/strong> in the winter garden, the extra money for insulation largely goes to covering a need you don&#8217;t have.

An uninsulated winter garden really is used in winter \u2014 for cooling down after the sauna, for morning coffee, for overwintering plants. The glass wall stops the wind and precipitation and keeps the space a few degrees warmer than the outside air. An infrared heater, fireplace or Bullerjan stove make it a comfortable place to sit even in frost.<\/p>\n<p><strong>How warm is a winter garden in winter?<\/strong><br \/>\nWithout extra heating, a cold winter garden is a few degrees warmer than the outside air, and the main benefit comes from the wind and rain shelter. On a sunny day the greenhouse effect adds to this \u2014 even in frost the glass space can warm noticeably above outside, comfortably onto the plus side. In our experience a warm body (e.g. coming from the sauna) can sit there comfortably for up to about an hour even at -10 to -20 \u00b0C. With an infrared heater or fireplace it stays cosy for longer.<\/p>\n<p><strong>Does a winter garden get too hot in summer?<\/strong><br \/>\nA properly planned winter garden does not. Tinted (solar-control) roof glass stops a large share of the high summer sun&#8217;s heat, and the openable side panels let the warm air out. In summer the sides slide fully open, so the winter garden becomes a shaded, airy outdoor terrace rather than a hot greenhouse. The clear side glass, in turn, lets the low winter sun warm the space.<\/p>\n<p><strong>Can you live in a winter garden year-round?<\/strong><br \/>\nAn uninsulated winter garden isn&#8217;t meant for year-round living as a heated room. For that there&#8217;s an insulated winter garden, which costs about twice as much. In our experience about 99% of clients don&#8217;t want it \u2014 the need is a pleasant seasonal and winter outdoor space, which a cold winter garden covers at about half the price.<\/p>\n<p><strong>Can a winter garden be heated?<\/strong><br \/>\nYes. Common solutions are an infrared heater (which warms the person and surfaces, not the whole air) and a fireplace or Bullerjan-type stove. We have built fireplace corners into winter gardens \u2014 we handle the flue and fire safety as part of the build. A point heat source suits a cold winter garden better than trying to keep the whole air volume warm.<\/p>\n<p><strong>Why doesn&#8217;t Klaaskoda build insulated winter gardens?<\/strong><br \/>\nBecause the vast majority of people don&#8217;t need a year-round heated glass room, and insulation doubles the price to cover a need most don&#8217;t have.
