When RZ-Ecoseal is dry it is completely waterproof not allowing water to penetrate the surface or affect the seal. The tests completed by Sheffield University followed a methodology based on BS EN 12086:2013

RZ-Ecoseal is a white, elastic mastic which transforms into a hard crust, like ceramic. This process happens when exposed to high temperatures derived from flames or intensive heat radiation from fire. The insulating capacity of the crust effectively extinguishes the flow of heat to treated surface.

​

RZ-Ecoseal combined with other parts of a penetration seal is tested according to EN13166 -3:2009 and classified, E160-E1120 depending on penetrating service, in accordance to EC13501-2:2016.

Due to RZ-Ecoseal being a sealant the product is flexible and moves with any changes in temperature whilst doing this it does not loose its integrity.

When dry its elastic properties does not affect the RZ-Ecoseal because RZ- Ecoseal binds to the surface not allowing any air or weather to get underneath the seal.

RZ-Ecoseal equalises the surface temperature not allowing for any changes in surface temperature.

Condensation test completed by Sheffield University 13th May 2019 comparing RZ-Ecoseal to rockwool and K-flex installation recognised below as system 1 and 2.

Findings: 

​- Condensation occurs on the surface of the pipe sealed with RZ-Ecoseal between 5 and 17 min from the start of the test and disappears at around 20 min.

- Condensation occurs on the surface of the pipes covered with Systems 1 and 2 from the beginning of the exposure until the temperature of the pipe surfaces reaches the dew point at 106 min and is still present at 120 min. 

RZ-Ecoseal does not allow water vapour to come through completes a full seal across the surface.

The tests completed by Sheffield University followed a methodology based on BS EN 12086:2013.

The test show that in comparison to K-Flex and Rockwool, RZ-Ecoseal lets 7 times less water vapour through.

RZ-Ecoseal is completely safe to apply and safe when on a system. (SDS Attached)

RZ-Ecoseal is completely safe and does not have any harmful ingredients in the product and the product does not release any gases or is harmful to user or environment.

RZ-Ecoseal has good insulative properties for a 1.5mm coating.
