Schilliger Holz CLT - 产品优势与质量标准

Q: What production and logistics advantages do the CLT panels offer?

The panels are produced with automated, high-capacity manufacturing for large output and high accuracy. They support cutting to size, individual surface treatment on both sides, and delivery directly to the construction site with optimized delivery times.

Q: How are panel quality and surface appearance classified?

Quality depends on the two main sides and is offered in B-quality (visible living area surface with repairs), C-quality (industrial surface with synthetic-filled defects), and D-quality (non-visible surface without aesthetic corrections).

Q: What are the stated CLT properties and fire performance requirements?

The brochure lists moisture content (10% ± 2%), key physical properties such as thermal conductivity and water vapor parameters, and a fire reaction class of D-s2,d0 according to EN 13501-1. It also specifies gluing with polyurethane (PUR), Type I EN 15425, solvent-free and formaldehyde-free.

All production steps are combined under one roof – from caps and finger joints of the slats to drying, gluing and intermediate storage to grinding and cutting. 4 SCHILLIGER HOLZ – NATURALLY FROM REGIONAL WOODS In our plants, we process wood from regional forests. In this way, we strengthen the regional forestry economy, minimize transport and make a significant contribution to a favorable ecological balance for your building project. CLT QUALITY CRITERIA Each panel is characterized by the quality of its two main sides. All combinations are possible. Different surface qualities are offered: B-quality: Visible surface for in the living area, sanded, defects repaired with wooden patches C-quality: Industrial surface, sanded, defects filled with synthetic materials D-quality: Non-visible surface, without aesthetic corrections PROPERTIES Application Wood species | Appearance, color & texture | | --- | | Knots
