Insulating plaster is an excellent option for improving energy efficiency through plastering. It contains materials that help reduce heat loss through walls and can be applied to interior and exterior walls.
Dry lining is a cost-effective way to improve thermal insulation and reduce heat loss through walls. It involves fixing plasterboard to the walls, followed by a skim coat of plaster, which helps to keep your home warm in the winter and cool in the summer.
External wall insulation is an effective way to improve thermal insulation, but it may not be suitable for all homes. It's particularly effective for older homes with solid or uninsulated cavity walls.
Proper ventilation is essential for maintaining indoor air quality and preventing moisture buildup and condensation. You can consider installing a ventilation system, such as a heat recovery ventilation system, to ensure proper airflow in your home.
