To improve thermal efficiency and keep the outdoor dining experience alive, there are several steps you can take:

Insulate outdoor seating areas: Adding insulation to outdoor seating areas can help keep heat in and cold air out. Glass enclosures are a great way to create a more enclosed environment while keeping that outdoor patio feel

Install outdoor heaters: Outdoor heaters come in a variety of styles and sizes and can provide heat to small or large outdoor seating areas. Consider installing a mix of overhead heaters and portable heaters to provide warmth where it's needed most.

Optimize seating arrangements: Arrange seating in a way that maximizes warmth and minimizes drafts.

By implementing these strategies, you can improve thermal efficiency and create a comfortable outdoor dining experience, even in cold or inclement weather.
