Characteristics of Wood Sandwich Panel


The Wood Sandwich Panel provides a very high thermal insulation thanks to its insulating core of high density extruded polystyrene foam, around 35 kg / m3. In the upper layer of the wood panel we find a water-repellent agglomerate of 16 or 19 mm, which protects against leaks and humidity that can damage the insulating core, considerably reducing the performance of the installation. This protection, together with the tongue and groove system of the Sandwich Panels, ensures correct performance under tile roofs.

The lower face of the wood panel can be manufactured in a wide variety of finishes, according to the characteristics of the project and the preferences of each client. Thus, we can choose between the most popular models made with friezes of different woods to other more particular solutions such as wood cement, plasterboard or several agglomerates. Whatever the termination chosen by the customer, we can manufacture Sandwich Panels in thicknesses of 30 to 120 mm to provide the thermal insulation required by each project. To learn more about the characteristics of each wood panel and its availability, we recommend consulting our sales team and they would offer you the best prices.

In addition to the exceptional image provided by the wood panel, its assembly is another advantage compared to other boards that have become a sandwich roof increasingly installed in a variety of projects. The tongue and groove system ensures the correct meeting between the Sandwich Panels while protecting against thermal leaks as well as moisture that can damage the polystyrene core and considerably reduce the performance of the wood panel. The sandwich plates are screwed directly to the structure, always ensuring three supports per wooden panel with three fixings in each one of them. It is preferable to place them in a quincunx to alternate the joints and reinforce the waterproofing of the sandwich cover. This simple installation considerably reduces the costs of the construction but guarantees exceptional performance.

As in other covers for sandwich sheet roofs or insulating panels for facades of industrial buildings, our wooden panels offer the quality certificates required by current regulations. This documentation is a guarantee for the customer, who can thus know in advance the performance of the wood panel to avoid problems with the installation later. The parameters included in this documentation have been evaluated in rigorous tests carried out by independent organizations, yielding values ​​that meet or even improve the levels established in the European framework. These characteristics are subject to each Sandwich Panel, so we recommend consulting our team if you need specific information on a wood panel. In this way, the customer is guaranteed to acquire the highest quality at the best price in PANEL SANDWICH GROUP.
