Heavier-weight velvet fabrics tend to provide more insulation and warmth compared to lighter-weight varieties. Fabrics with a denser pile and thicker backing may offer greater thermal insulation properties, making them suitable for colder environments.The density of the velvet pile can affect its ability to retain heat. Fabrics with a higher pile density typically provide better insulation and warmth by trapping more air within the fibers. However, excessively dense piles may also limit breathability and ventilation.
Some velvet fabrics, especially those used for upholstery or curtains, may have a backing material that adds an extra layer of insulation. Backings can vary in thickness and composition, with options ranging from lightweight linings to heavier interlinings or thermal coatings.Velvet curtains or upholstery can be layered with other fabrics or insulating materials to enhance their warmth and thermal performance. Adding a thermal lining to curtains or using velvet upholstery over foam padding can increase insulation and improve heat retention.
