Although the product itself has not been UK fire rated there is the US information below.
However we have sourced clear flame retardent sprays that can be applied on a wall of Everblocks would render the blocks Fire Rated Class '0' and obviously Fire Rated Class '1'

USA testing data:
 (Underwriters laboratory Yellow Card Number): signifying that EverBlock material embodies a slow burn rate of 2” per minute for a 2” wide by 0.5” in thickness test sample.  Furthermore, UL94HB signifies that the material will not flare up when exposed to an open flame.

 Hot wire ignition rating: 3


R-Value for full and half blocks is estimated at R-2 based on six inches of air space, two exterior walls, and one interior ribs. Note: This is for individual blocks and complete wall values may vary based on pattern and arrangement of blocks.

Building with EverBlock

Connecting Modules


Each Block has a series of connector lugs, that are designed to nest into the underside of the next block. Sections can be staggered in 3" intervals, so that 1, 2, 3, or 4 of the lug sets nest into the other block. 

Lugs are designed to pressure fit into corresponding slots on the underside of the block on top. Underside ribbing provides structural support and a tight fit. 

To begin, simply align each new block over the block below and center over the lugs that you want to connect with. Press down until you can't push any further and blocks are fully connected.


Utilize a combination of block types, lug spacing, and block direction to create your object.  Alternate as needed to create unique designs and consider the structural implication of aligning seam lines (when seams are aligned the construction is not as strong and we suggest staggering blocks).  

Change block rotation to provide strength and to extend your object in another direction. This is ideal for buildings, displays, and other multidirectional structures. 

Use smaller (4 lug) blocks and different spacing (i.e. 2,4,6, or 8 lugs connected) to create more detail and resolution for your objects and based on your specific needs. 


EverBlock Finishing Cap

To create a more finished look for your object, we have created finishing pieces that are smooth topped pieces that snap to the top of your object.  The are used to cover the connector lugs of each piece and can be used to create tops for tables, benches, and other objects that require a more finished look. 

You may also attach third party shelves and panels to create desks, displays, and other interesting objects. 

Reinforcing Your OBject

EverBlock Reinforcement Pin

Depending on the size, application, or type of object you are building, it may be necessary to reinforce your object for additional stability. We suggest utilizing 1/2" rebar or wood, metal, or PVC dowels, rods, or tubing to provide added strength. You can also use the EverBlock reinforcement clips to tighten the fit between blocks, reinforce your structure, and so that objects can be transported more easily in one piece. Insert these into the integrated channels that run through each block and into the blocks below or above.  Rebar or other support material can also be inserted into or fastened to the ground or support base below for additional strength.   

Once inserted, the support rods will keep blocks from separating and provide additional wind loading capabilities and structural strength.  Threaded rods may be used in conjunction with nuts to more tightly connect blocks to each other and enhance strength further. 

No Tools, Glue, or Material Handling Equipment Is Required to Build Structures of Nearly Any Size
