5ft French Doors

There are several ways that French patio doors can be thermally efficient:

1. Energy-efficient glass: French patio doors can be equipped with energy-efficient glass, which is designed to reduce heat transfer and keep your home more comfortable. Energy-efficient glass can help to reduce your energy bills by keeping your home cooler in the summer and warmer in the winter.
2. Insulating frames: The frames of French patio doors can be made from materials that have good insulating properties, such as uPVC. These materials can help to reduce heat transfer and keep your home more comfortable.
3. Weatherstripping: French patio doors can be equipped with weatherstripping, which is a sealing material that helps to reduce air leakage around the door. Weatherstripping can help to keep your home more comfortable by preventing drafts and reducing heat loss in the winter.
4. Low-emissivity (Low-E) coatings: French patio doors can also be equipped with Low-E coatings, which are thin layers of material applied to the glass to reduce heat transfer. Low-E coatings can help to keep your home more comfortable by reflecting heat back into the room in the winter and blocking heat from entering the room in the summer.

These features can help to reduce heat transfer and keep your home more comfortable year-round.
