How to Winter-Proof Your Attic

Jan 13th 2021


Doors and windows are generally on the top of your list when it comes to preparing for colder temperatures. However, you may want to look up, specifically toward your attic. The very warm air that should be keeping your home cozy and warm during the winter months may be escaping from the attic at alarming rates. Fortunately, we are here to tell you our little secret about winter-proofing your attic:

The Effects of an Attic that isn’t Properly Maintained

Air leaks around windows and doors tend to be the most noticeable. However, a lack of proper insulation and ventilation in your attic could add up to the equivalent of a window being opened halfway for the entire day!

Addressing Air Leaks

Attic hatches and floors are among some of the most common areas for air leaks found throughout your home. Test the air in your attic by holding up a candle or thin piece of toilet paper. If you begin to see any erratic movements, hold your hand up to the area and you’ll probably feel the chilly air! Use a piece of colored tape or some other marker to mark it as priority for sealing.

You can use caulking and sealant products to seal the majority of air leaks (up to ¼ inch in size) in your attic space. Use heat-resistant caulking for areas that may be near your chimney and weather-resistant sealant for any areas facing externally. Silicone Depot offers affordable sealant and caulking products such as this silicone sealant that are heat and weather resistant.

Improving Attic Insulation

Increasing attic insulation is a fairly involved DIY project, but it’s completely realistic to add to your weekend to-do list with the right materials. This expanding foam spray for Silicone Depotis great for sealing any larger gaps (¼ to 3 inches wide). The spray comes with an applicator nozzle for easy use and doesn’t hold moisture. Common areas to ensure there’s proper attic insulation include where the walls meet the floor and any dropped ceilings.

Finding gaps and leaks in your attic can be tricky because they may be covered by insulation. Look for any dark or dirty spots in the insulation as well as any patches of frost or ice to signal where the gaps may be located.

Ensuring that your attic is ready for winter will prepare your entire home for the cold weather. These tips are also transferable to use in the warmer months and help lock air-conditioned air within the home!
