Visqueen Zedex Non-Combustible Flexi Preformed Units: What are they? And do Multifix stock them?

One common question that we get asked by Brickwork Contractors is whether we stock Visqueen Zedex Non-Combustible Flexi Preformed Units, otherwise known as flexicorners.  

The answer to that question is that you can purchase them through us, but as they’re a bespoke product, they’re not something we hold in stock.  

As such, the ordering process is a little different. In this article, we’ll explain how to purchase them through Multifix and also what makes flexicorners so valuable.  

Firstly, what are these flexicorners?  


Flexicorners are manufactured from non-combustible DPC and are 90-degree corner units that can be used both internally and externally. They also have a 150mm vertical rise and a 100mm vertical fixing flange. 

In addition, if a flexicorner has been incorporated into a brickwork outer leaf, each unit is suitable for a cavity width of up to 50mm. 

Otherwise, they are available for cavity width ranges 40-100mm, 100-150mm, 150-200mm, 200-250mm and 250-300mm. 

How can I order a flexicorner from Multifix? 


As mentioned earlier, flexicorners are bespoke products, so there’s a different process before we can supply them to you.  

First, we would need the drawings involved with the project to understand the product dimensions that you need and to enable us to provide you with an accurate quote.  

The lead time for bespoke flexicorners is five to seven days from quote approval, depending on the size of the flexicorner or the quantity. 

What other benefits do flexicorners have? 


The flexicorners have a host of other features, which make them valuable assets for brickwork specialists. They are compliant with UK Building Regulations for fire safety and are A2 – S1, d0 and BS EN 13501-1:2018 certified. 

They are also off-site factory manufactured, which reduces the risk of any water ingress, while they also provide an allowance for any site tolerances.  

Most importantly though, they are part of the Visqueen Zedex Non-Combustible DPC System, which means they can be used in residential dwellings, in addition to low-rise and multi-storey residential public, commercial and industry developments with a masonry inner leaf.
