Now if you open it just slightly, you let in enough fresh air to stay comfortable without overheating, even in cold weather.<\/p>\n\n\n\n<p class=\"has-x-large-font-size\">Your home works in much the same way.<\/p>\n\n\n\n<p class=\"has-large-font-size\">When insulation is added (like putting on the coat), the way the building behaves changes. It holds heat more effectively, which is great, but it can also lead to overheating and moisture build-up (like getting too warm on that walk).<\/p>\n\n\n\n<p class=\"has-x-large-font-size\">That\u2019s why you need a way to control.<\/p>\n\n\n\n<p>Trickle vents or other forms of controllable background ventilation act like the zip on the coat. They allow you to regulate how much fresh air enters your home, which is especially important in rooms where everyday living and occupancy create moisture and stale air.<\/p>\n\n\n\n<p class=\"has-x-large-font-size\">Now think a bit deeper about the coat itself. <\/p>\n\n\n\n<p>What kind of material is it? Is it breathable like wool, or waterproof and less permeable? Does it allow moisture to escape, or does it trap it inside? And what about the person wearing it\u2014are they jogging or just walking?<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<blockquote
