A blue stone door sill with upstand provides a clean finish and protects your facade from water seepage. Thanks to the upstand, you prevent rising damp and give your facade a durable and aesthetic appearance.

Easily assemble your ideal flat door sill with upstand and drip groove here. Choose the desired finish, thickness, length and width. Then add any options. The price per piece and per m² is calculated automatically. In addition, you can adjust the chosen finish at any time. Add the product to your shopping cart and complete your order. Delivery time is approximately 2 weeks.

Please note that the thickness (or height) given is the height of the back surface. The top surface is 1 cm lower.
Example: a sill of 4 cm high is 3 cm thick with an upstand of 1 cm. In this case, you specify a thickness of 4 cm.

Is the length greater than 180 cm? Then we automatically split the sill into several pieces. You can easily enter the desired division via the additional fields that appear.
