The Purpose of Weatherstripping

The primary purpose of weatherstripping is to prevent drafts and air leaks, keeping both cool and warm air in, and cold or hot air out, depending on the season. Effective weatherstripping ensures that conditioned air stays inside where it belongs. This means your HVAC system doesn’t have to work overtime, leading to lower utility bills.

Incorporating the care and replacement of weatherstripping into your home maintenance routine is essential to achieving better energy efficiency. 

Common Problems Caused by Poor Weatherstripping

When windows are inadequately weatherstripped, several issues can arise that negatively impact your home. Here are some common problems homeowners experience:

1. Persistent Drafts

Gaps around windows or doors allow cold air to seep in during winter and hot air to enter in the summer. This leads to a constant battle with your thermostat, causing discomfort and increased energy bills.

2. Increased Energy Costs

Poorly sealed windows or doors can account for up to 25% of your home's heat loss. As a result, heating and cooling systems work harder, consuming more energy and increasing utility costs.

3. Impact on Indoor Comfort

Cold spots near windows can make certain areas of your home uncomfortable. Inconsistent temperatures can also lead to reliance on space heaters or extra blankets, which only adds to energy waste.

4. Reduced HVAC Efficiency

When drafts are present, your heating, ventilation, and air conditioning (HVAC) system may struggle to maintain desired temperatures. This inefficiency can shorten the lifespan of your system and lead to costly repairs.

Addressing these issues through effective weatherstripping enhances comfort and reduces unnecessary expenses, which can positively affect your budget.

Types of Weatherstripping

1. Adhesive Backed Foam Tape
