We hold selected K-FLEX products and sizes in stock. Other legitimate catalogue items can be ordered with additional supplier lead time where stated on the product page. We will confirm the expected dispatch date after the order is received when an item is supplied to order.

Technical Selection

K-FLEX products span different insulation materials, temperature ranges and fire classifications. Check the individual product specification before ordering, particularly where the installation must satisfy BS 5422:2023, Building Regulations or a project-specific fire, heat-loss or condensation-control requirement.
