A sunroom can be a beautiful addition to any home, offering a place to relax and enjoy the sun during the warmer months. But sunrooms can become uncomfortable and unusable during colder winters if not appropriately heated.

There are several steps you can take to keep your sunroom warm during the winter months. In this guide, we’ll discuss some tips for heating your sunroom in the wintertime, helping you get the most out of your space all year round.

12 Ways to Keep Your Sunroom Warm in Winter

Sunrooms are a great way to bring the outdoors into your home, enjoying the winter weather while protected from the elements. But sunrooms can often be too cold to properly enjoy during winter.

Fortunately, there are plenty of ways to keep your sunroom warm and cozy while still soaking up the natural light. From insulating windows to adding a space heater, here are several ways to keep your sunroom warm throughout the year.


To prevent heat loss from your sunroom, you should insulate the exterior walls. Not only is insulation great for keeping your sunroom warm, but an adequately insulated sunroom can also help reduce your overall heating costs.

Insulating walls, floors, and ceilings are essential for a peaceful living environment, especially in noisy cities where soundproofing is critical to reducing noise pollution. Insulating your walls and ceiling is an intelligent way to save money while creating a peaceful atmosphere.

Insulation helps regulate temperature, prevent water damage, reduce energy costs, and promote comfort by providing an ideal climate in any season.

Upgrade Windows

Upgrading your sunroom with new windows will bring in the light and keep out the cold. With high-quality windows, you can enjoy the beautiful outdoor scenery while keeping the inside of your sunroom comfortable and warm.

Drafty windows can lead to higher energy usage and higher bills in the winter due to a longer-running furnace. Upgrading to energy-efficient windows is an excellent choice for your sunroom as it will keep it warmer in the winter and cooler during the summer.

As a result of blocking out the heat from the sun, air-conditioning costs can be reduced, and you won’t have to use as much additional heating due to drafts during the winter. The right window —type can also provide insulation to help further reduce energy costs. Investing in quality windows will make a big difference in how you enjoy your sunroom for years.

Weather Stripping

Ensuring you have adequate weather stripping is an integral part of preserving the integrity and comfort of your sunroom. It helps to keep out drafts and moisture while also providing insulation against extreme temperatures.

Weather stripping is essential to a structure, protecting it against external elements. Polypropylene is the best material for this purpose, as it lasts much longer than felt or other synthetic materials. Adding a mylar fin to your polypropylene weather strip ensures that it will remain engaged even when wet, helping ensure your sunroom is moisture-free and comfortable even in the harshest climates.

Ceiling Fan

Ceiling fans are a great way to enjoy your sunroom in winter. They often provide a gentle breeze in warm weather and circulate rising warm air down from the ceiling. This makes it easier to maintain a comfortable temperature and can help ensure your sunroom is always cozy and inviting.

Carpet or Rugs

Carpets and rugs can quickly turn your sunroom into a cozy area for the colder seasons. With the right carpet or rug, you can quickly create an inviting and comforting atmosphere.

Carpets and rugs provide warmth and comfort, making it easier to relax in your sunroom during the cold winter months. They also add an additional layer of insulation to the floor, as well as colour and texture to the room, creating an inviting atmosphere that will make you want to stay in your sunroom all winter.

Whether you choose a traditional carpet or something more contemporary, like a shag rug, plenty of options are available for making your sunroom even more enjoyable during the colder months.

Thermal Curtains

Thermal curtains are a fantastic way to keep your sunroom warm, even when temperatures drop. Enjoy all the best parts of the space while these curtains help retain warm air and help reduce energy costs by keeping cold air out. With thermal curtains, you can enjoy your sunroom all year round without worrying about feeling too cold or wasting energy on heating costs.

Window Tinting

Window tinting is another way to enjoy your sunroom in winter without worrying about the cold temperatures. With window tinting, you can keep the heat inside and enjoy the warmth of your sunroom even during the coldest months of the year. Window tinting is an excellent solution for anyone who wants to create a comfortable and protected space in their home. It saves money and offers ultimate privacy and sun protection in any season.

Plastic Insulation Window Kits

When enjoying a sunroom in the winter, plastic insulation window kits can provide a temporary solution. They offer an easy answer for keeping the warmth of summer in your sunroom all year round.

Not only do they keep out the cold air, but they also reduce energy costs by providing an extra layer of insulation. With these kits, you can enjoy your sunroom without worrying about losing heat during the cold winter.

Baseboard Heaters

Baseboard heaters can help homeowners enjoy their sunroom in the winter months. Not only do they provide efficient and cost-effective heating, but they also offer a comfortable and cozy atmosphere.

Baseboard heating makes your sunroom cozy and inviting, so you can enjoy it regardless of the cold weather outside.

Portable Space Heaters

Portable space heaters easily provide warmth and comfort in a sunroom allowing homeowners to take in the beauty of the surroundings without bundling up in heavy coats and blankets. With various sizes, styles, and features available, there is sure to be a portable space heater that can help you make the most of your sunroom during the colder months.

Fireplace or Stove

Utilize a fireplace or stove to make your sunroom warm and inviting in the winter, allowing you to appreciate the beauty of nature from the comfort of your home. Ultimately, choosing between a fireplace or stove for your sunroom depends on what type of atmosphere and heating you’re looking for—but either one will make your winter days spent in the sunroom even more enjoyable!

Extended Existing Ductwork

Extending existing ductwork from the home into the sunroom is another heating solution that can be utilized. This option will provide warmth and comfort while allowing you to maximize the use of your sunroom.
