Understructure

Understructure for the windows consists of a rigid and durable catch strip with mounting anchors. In the upper part, called the head, a special T-shaped PVC strip is embedded. The strip stiffens the entire element. The head is milled with fasteners and closely fitted to a specific profile. This is crucial for proper sealing and thermal protection. Its shape is each time adapted and matched to the window structure. The elements are to constitute a solid and warm foundation for all kinds of door and window thresholds. They can also act as extensions. Klinaryt and Purenit available.
