Schlegel Door & Window Seals

Schlegel are market leaders in perimeter sealing technology and manufacture high quality and innovative door and window seals.

Schlegel seals comply with all relevant British Standards performance standards and are designed to last.

The Aquamac range is specifically for timber frame applications, having a paint and stain resistant design that makes decorative maintenance quicker and easier.

The Q-Lon range on the other hand is designed to be over painted or stained, for décor matching, without this affecting the performance of the seal.

The Sharkseal range is designed for sliding applications, such as patio doors or sliding windows and there is also a version suitable for fitting where the attachment area is very narrow.


Schlegel's AQUAMAC Weatherseal stays looking good for years, its water repellent foam is unaffected by rot, mould or mildew and will not freeze to mating surfaces. The unique design makes Aquamac impervious to paint and stain, which can be a big time saver when it comes to decorative maintenance. AQUAMAC maintains consistently high standards of energy efficiency, often exceeding any long-term window performance guarantees.
