Birtley Medium Duty Steel Cavity Wall Lintel 1500mm x 154mm - MD90

The MD90 Cavity Wall Lintel is engineered for medium-duty applications in cavity wall constructions with a cavity width of 90-105mm. This lintel is specifically designed to work with solid, fully jointed blockwork infill to the inner leaf. With its superior Supergalv coating and post-fabrication galvanizing, it offers exceptional durability and longevity, making it a reliable choice for both structural integrity and thermal performance. The MD90 also provides significant improvements in thermal bridging, enhancing energy efficiency in building projects. Key Features : Cavity Width: Designed for cavity sizes of 90-105mm, suitable for both 100mm inner and outer leaves. Solid Blockwork Infill Requirement: Requires solid, fully jointed blockwork infill to the inner leaf for effective load distribution. Supergalv Coating: Provides superior life expectancy and corrosion resistance, ensuring longevity. Thermal Performance: Delivers up to a 55% improvement on SAP default values in thermal bridging, promoting energy efficiency. Durable Material: Constructed from mild steel S275JR to BS EN10025-2:2004, ensuring strength and reliability. Fire Rating: Offers 60 minutes of fire resistance with a two-coat plaster finish. Post-Fabrication Galvanizing: Guarantees that all surfaces are protected against corrosion, eliminating areas of inferior paint protection.
