Yesterday marked an exciting milestone as we completed the final CLT shear wall test after an intense two-and-a-half months at Virginia Tech. During this period, Adam Phillips, PE, and I tested over 46 CLT shear walls using the SDPWS-provided shear connections, alternative connections to those in SDPWS, and combinations of both SDPWS and alternative shear connections. As you can see in this video, there are no visible shear connectors between walls and plates, making this solution more appealing to building owners, architects, and other stakeholders. Additionally, a key advantage of this solution is its easy disassembly. The threaded rods are visible for testing but can be concealed within the wall. With this solution, we achieved a lateral deformation of approximately 4% of the inter-story drift. A huge thanks to ARPA-E for funding this project through the HESTIA program!

Here are several key advantages that are driving the increasing adoption of composite rebar in the industry.

🚆 Fascinating GFRP rebar case study from Miami's Metrorail AirportLink: How glass fibre-reinforced polymer (GFRP) rebar is revolutionizing transit infrastructure! Electrical isolation was enhanced by using glass-fibre-reinforced polymer (GFRP) reinforcing bars, making the structural connections between guideway structures, and cast-in-place pedestals and plinth pads. Key benefits discovered: • Eliminates stray current corrosion issues common in steel rebar • Can be easily cut and modified on-site with basic tools • Perfect for rail systems where electrical isolation is crucial • Allows simpler prefabrication of reinforcement cages Thanks to Doug Gremel for his insights.

EMF 400 - 384 Successfully delivered to Australian customers - These mixed flow end suction pumps are sometimes termed "short & fat" somewhat derisively because they deliver large flows at relatively small heads. Designing them successfully is, however, not very simple and it requires the special skills of our designers to keep the shut-off head and power control, to obtain high efficiency, and to keep an unavoidable recirculation gone as far away from the operating zone as possible We are happy that EMF 400-384 meets all these requirements with splendid ease. #mixedflowpumps #endsuction #splitcase #centrifugalpumps #design #power #power #efficiency 

Did you catch our recent fire tests with Fire Doors by Solar and Solar Windows Ltd., showcasing Pyroguard Advance? Pyroguard Advance is our innovative, cuttable fire safety vision panel glass, designed specifically for the GRP Composite FD30S Fire Door market. Engineered for larger pane sizes, it fully meets EN Standards ensuring superior fire performance and safety. In collaboration with Fire Doors by Solar and Solar Windows Ltd., we successfully completed bidirectional testing to EN1634-1 and EN1634-3, using 7mm and 8mm Pyroguard Advance glazed units in door and fanlight configurations. These results significantly surpassed standard requirements, achieving an EW30 fire classification and offering enhanced design flexibility. And there’s more to come! With further internal tests underway on glazed partitions, Pyroguard Advance is set to push the boundaries of fire safety and deliver even more advanced solutions. Fire Doors by Solar and Solar Windows Ltd are already incorporating Pyroguard Advance glazed units into their manufacturing processes. Together, we’re driving innovation and raising the bar for fire safety. Talk to us today to find out more 👉 https://buff.ly/3rIwSA9 #FireSafety #Glass #Cuttable #FireDoors #Innovation

If you regularly read our posts, you’ll know that transparency is one of our guiding principles as a business. With this in mind, we’ve now developed a new technical video which features third party fire testing undertaken before the launch of Protect FrameSafe FR, our new Class A2-s1, d0 flame retardant external wall membrane.  The video shows the product tested to BS EN 13823, where FrameSafe FR was fixed to both A1 and A2 substrates, with laps sealed with our Protect FR sealing tape. This ensures a fully fledged membrane system that achieves an A2 reaction to fire classification. The product was also tested free hanging and achieved the same A2 result. Watch the video below to see how the membrane performs, providing reassurance of the product's integrity for use across all building heights. Detailed fire test classification reports are available from our Technical team. Contact us on info@glidevaleprotect.com to request them.
