2 LP SolidStart Engineered Wood Products It s More Than Our Products. It s The Way We Do Business. At LP Building Products, we re proud to offer integrated building solutions that work together to save you time and money, and proud that our products offer so many environmental benefits. But something else sets us apart: the way we do business. We believe that sustainability means acting in a way that protects the environment, embraces social responsibilities, and builds economic prosperity today and for future generations. That is why we set a higher standard by using both PEFC and SFI certified timber procurement systems. Our systems are certified by the same third-party that certifies sustainable forestlands which helps ensure our timber comes from well-managed, non-controversial sources. There s Timber. And Then, There s Better. Your reputation is built on the strength of your materials. So it makes sense to build with LP SolidStart Engineered Wood Products based on LP s advanced technology. LP SolidStart products work together in a building system that delivers practical advantages during construction and for decades to come, and meets or surpasses the regulations and standards applicable in the United Kingdom and Ireland. BV-SFICOC-US PEFC/ Builders can offer their customers the peace of mind that comes with a lifetime limited warranty on all LP SolidStart Engineered Wood products. If your LP SolidStart products ever develop problems due to a non-conformity, LP will cover all reasonable repair and/or replacement costs as per the conditions of our Lifetime Limited Warranty.

LP SolidStart I-Joists start straight and stay straight. They re more uniform in strength, stiffness and size than solid timber and are less likely to warp, shrink, twist, split or crown. They re light in weight and come in longer lengths and deeper depths so floors can be designed with fewer pieces, saving installation and material costs. LP SolidStart Laminated Strand Lumber (LSL) offers strength and consistency to a broad range of applications in residential and light commercial applications including primary floor beams, trimming beams, lintels, posts, purlins and rim boards. Available in multiple grades up to N/mm 2 MOE (LSL-G) and a variety of sections, it delivers enhanced design flexibility. Edges and ends are sealed for added moisture protection. LP SolidStart LSL shows superior dimensional stability and connection capacities. LP SolidStart Laminated Veneer Lumber (LVL) is ideal for single or multiple-ply beams, lintels, trimming beams and other primary carrying applications. Manufactured from ultrasonically graded veneers and bonded with exterior grade adhesives, LP SolidStart LVL delivers greater -carrying capacity than traditional timber. Available in multiple grades and a wide variety of widths and lengths it provides tremendous design flexibility, as well as superior dimensional stability. Comes standard with a water-resistant SiteCote providing additional weather protection. Manufactured for strength and consistency, our LP Rim Board products are precision cut to work seamlessly with LP SolidStart I-Joists and LSL and LVL beams. That makes them ideal for supporting vertical and lateral wall s as part of a floor or roof framing system. Options include rim board manufactured from LSL or LVL in a wide range of depths and thicknesses. LP Rim Board provides a dimensionally stable flat surface, consistent edge nailing capacity and high vertical capacity suitable in most multistory applications CPD CPD-0840 ETA-12/ CPD-0844 ETA-13/ CPD CPD-0817 EUROCODE 5 3

Multiple span joist Instead of two single spans, use one multiple span joist to reduce deflection. 2. Deeper joist Significantly improve the performance by using a deeper joist than required. 3. Wider flange joist Reduces out-of-plane vibration of the bottom flange plus improves performance and feel of floor decking. 4. Reduced joist spacing Proportionally increase the floor stiffness by reducing required floor spacing. 5. Glued and fixed decking Increases floor stiffness due to composite action of joist and decking. 6. Thicker floor deck Improves composite action while reducing deflection and engages more joist. 7. Directly applied ceiling Improves floor feel as ceiling directly attached to joist reduces vibration. 8. Strutting or blocking Helps the floor act as a unit and increases the stiffness perpendicular to the joist direction. 9. Stiffer support beams Reduces compound deflection of the floor system when supported by stiffer beam. 13

19 Cantilevers Joist Reaction Calculation LP I-Joists can cantilever up to 150mm to support a -bearing wall over a brick finish. Depending on the Calculated Factor Reaction (CFR), the joists may require reinforcement. If the CFR is less than the End Bearing Resistance w/o WS (page 4), then no reinforcement is required.

26 Handling and Storage Guidelines and Warnings Warning: Failure to follow good procedures for handling, storage and installation could result in unsatisfactory performance, unsafe structures and possible collapse. Keep LP SolidStart Engineered Wood Products dry. Un products carefully, by lifting. Support the bundles to reduce excessive bowing. Individual products shall be handled in a manner which prevents physical damage during measuring, cutting, erection, etc. LPI Joists shall be handled vertically and not flatwise. Keep products stored in wrapped and strapped bundles, stacked no more than 0mm high. Support and separate bundles with 38x90mm (or larger) bearers spaced no more than 0mm apart. Keep bearers in line vertically. Product shall not be stored in contact with the ground, or have prolonged weather exposure. Use forklifts and cranes carefully to avoid damaging products. Do not use a visually damaged product. Call your local LP distributor for assistance when damaged products are encountered. For satisfactory performance, LP SolidStart Engineered Wood Products shall be used under dry, covered and well-ventilated interior conditions in which the equivalent moisture content in timber will not exceed 16%. Use fabric slings Align bearers one above the other 0mm max. Hard, dry, level surface 1000mm max. 0mm max. DON T put holes too close to supports. DON T cut flange for pipes. WARNINGS The following conditions are NOT permitted! Do not use damaged products without first checking with your local LP distributor. Refer to hole chart for correct location. DON T overcut hole and damage flange. DON T use nails larger than 3.75 x 75mm Refer to Joist End Nailing detail for correct sizes and locations. DON T make hole with hammer unless knock-out is provided. DON T hammer on flange and damage joist. DON T cut beyond inside edge of bearing. DON T cut or notch flange. DON T support I-Joist on web. DON T drill flange. DON T DON T 26

27 1.0m temporary ing zone Safety Bracing xxx Notes 1. All timber blocks, hangers, and struts must be completely installed and properly nailed. 2. Lateral strength must be provided by a diagonally braced and blocked system comprising a minimum of 3 adjacent joists in each bay. In long bays, install additional systems spaced not greater than 15.0m. 3. Ends of cantilevers require safety bracing on both the top and bottom flanges. 4. With bracing installed as above and proper LPI Joist support, construction materials may be stored within 1.0m of a support (each side of interior supports) provided the is uniformly distributed between several joists and does not exceed 255 kg per joist. 5. When all decking has been permanently attached to each properly supported LPI Joist, a maximum of 255 kg per joist may be placed on the system at any point. Remove safety bracing as permanent decking proceeds Important! Traditional masonry hangers will not support construction s without a minimum of 675mm of cured masonry construction above hanger level. Consult the Hanger Manufacturer for information on the correct installation and use of masonry hangers. Alternatively, the floor can be supported by temporary works designed for the purpose. See Notes 4 and 5 above for maximum construction s. 2.4m max. All longitudinal safety bracing must be attached to a section of diagonally braced and blocked LPI Joists LPI Joists on hangers or built in 2.4m max. All bracing to be 19 x 89mm min., fixed at every joist location with two 3.35 x 65mm nails 600 mm 2mm 38 x 125mm timber blocks or LPI blocking panels are required over two bays (min.) WARNINGS Joists are unstable until braced laterally! The diagram below shows elementary rules to ensure safety during erection which shall be in addition to building safety regulations. This diagram covers safety bracing only and applies also to timber frame construction. DON T walk on unbraced floor joists (falling hazard). DON T store s away from the supports. DON T install decking on unbraced floor joists. 600 mm 2 mm DON T 27
