"Particleboard Flooring provides major cost savings through its economy and through lighter construction allowing reduced foundation cost. Installation times are reduced since dry trades only are involved."


Las viguetas prefabricadas pueden clasificarse en los siguientes tipos:

    a) Madera-tablero
    El alma está formada por dos tableros contrachapados o de virutas orientadas y la cabeza es de madera aserrada, laminada o microlaminada.
    Las secciones pueden ser en cajón o en doble T
    b) Madera-metal
    En esta caso el alma está formada por una celosía metálica o una chapa plegada que se une mecánicamente a las cabezas de madera.

Laminated veneer lumber (LVL) is an engineered wood product that is a layered composite made of wood veneers and adhesive. LVL was first used during World War II to make airplane propellers, and since the mid-1970's has been available as a construction product for beams and headers where high strength, dimension stability and reliability are required...

LVL is used primarily as structural framing for residential and commercial construction and is well suited for applications where open web steel joists and light steel beams might be considered...


APA Performance Rated I-Joists

 

I-joists can be manufactured using solid sawn lumber or structural composite lumber for the flange components, and plywood or oriented strand board for the web. This versatility allows the manufacturer to make the most efficient use of wood fiber resources in their region while producing products that consistently perform to known standards.
