Feedback on the use of Rockfleece B Energy from Rockwool

An alternative combining quality and durability

"Our choice to switch to a weldable system is based on quality and durability over time"

Rockfleece B Energy consists of a glass veil facing and allows you to weld in full. Used in a thickness of 140 mm on this new building site of 950 m2 for a materials distribution sign, the insulating panel provides, according to Hervé Soubeyrand, "Better adhesion to the final waterproofing complex while limiting the number of fastenings on the roof". It is precisely for these reasons that Sleico, which directs its offer towards durable and welded technical solutions, was curious to try this new insulator.

Consequence: a reduction in hallmarks with subsequent use - such as those resulting from traffic on the roofs - which thus ensures the durability of the installation over time. The product is also subject to a 25 year warranty.

"It's very good value for money and a good sealing system"

The use of welded in full also makes it possible to dispense with the use of reinforced systems generally much more expensive. The product therefore has a double advantage for sealers: while presenting a "Back in time much better than a basic bilayer system" and therefore a very good quality of the sealing system, this insulating panel keeps the affordable cost of a weldable.

Improved working conditions for better productivity

Based on a glass veil and no longer on a bitumen, Rockfleece B Energy facilitates the work of installers. Indeed, this new solution of welded in full makes the cutting of the product simpler, especially since it does not pollute the tools during handling. The result is an improvement in working conditions on construction sites and, by extension, a significant improvement in productivity for the sealing company. It also provides a 0,036 lambda solution for solid welded technologies, which reduces the thickness and weight of the panels compared to conventional bitumen-coated panels.
