The kit includes a crystal clear plastic film that, when heated with a standard handheld hair dryer, shrinks tight and wrinkle-free to create a transparent thermal barrier. Double-face tape is included for attachment to the window frame. Installation requires no special tools and is suitable for metal, painted wood, varnished wood, or vinyl clad frames. HVAC service technicians and building maintenance professionals commonly use products like this to improve envelope efficiency in residential and light commercial settings.\u003c\/p\u003e\n\u003cp\u003eThis kit is sized for extra large windows and covers a single opening up to 62 inches wide by 210 inches tall. It is intended for interior application and is well suited for residential retrofit weatherization projects, rental property winterization, and seasonal energy-loss reduction. The plastic sheet installs on the interior side of the frame and is removed at the end of the heating season without damaging most frame finishes when used as directed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCrystal clear film maintains natural light transmission after shrinking\u003c\/li\u003e\n  \u003cli\u003eShrinks wrinkle-free using a standard handheld hair dryer — no heat gun required\u003c\/li\u003e\n  \u003cli\u003eDouble-face tape included for frame attachment\u003c\/li\u003e\n  \u003cli\u003eCompatible with metal, painted wood, varnished wood, and vinyl clad frames\u003c\/li\u003e\n  \u003cli\u003eExtra large coverage area: 62 inches wide by 210 inches tall\u003c\/li\u003e\n  \u003cli\u003eInterior installation keeps the insulating air pocket on the warm side of the glass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement-grade interior window insulation kit suitable for extra large residential or light commercial window openings up to 62 inches by 210 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed from the interior and does not require licensed trade credentials, though building envelope specialists and HVAC technicians frequently apply these kits as part of a broader weatherization scope. Clean the frame surface thoroughly before applying the double-face tape to ensure adhesion. Apply the plastic film to the tape perimeter with moderate tension before shrinking, and use a handheld hair dryer in a slow, even pass to shrink the film flat. Avoid using an open-flame heat source or high-temperature heat gun, as these can melt or distort the film.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoverage Width\u003c\/strong\u003e: 62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoverage Height\u003c\/strong\u003e: 210 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Indoor use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrame Compatibility\u003c\/strong\u003e: Metal, painted wood, varnished wood, vinyl clad\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Hardware\u003c\/strong\u003e: Double-face tape\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 per case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: THERMWELL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: V75H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FROST KING","offers":[{"title":"Default Title","offer_id":51558971146546,"sku":"V75H","price":119.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac07060a4766df2c282a05225d7a9de0.jpg?v=1786424431","url":"https:\/\/voomisupply.com\/products\/thermwell-v75h-shrink-window-insulation-kit-62x210-in","provider":"Voomi Supply","version":"1.0","type":"link"}
