accoya®，high performance modified wood product, has been selected as the wood of choice by HPP architects for the renovation of the German Embassy in Washington DC.
Accoya Modified Wood Helps Green Home Project In Bid To Achieve Platinum LEED Certification
安静的替代传统的木框架方法。近年来，随着建筑商努力提供更耐用的产品，使用更环保的建筑方法，并降低成本，sip越来越受欢迎。根据AMA Research, SIPs是目前市场上增长最快的新建筑方法。< / p > < / div >
In today’s construction world, where green is the future, it pays to know about building techniques that not only count toward a green building rating but can actually reduce up-front costs. One such method is known as Advanced Framing, sometimes called Optimum Value Engineering (OVE). Advanced Framing takes a good hard look at the way we frame buildings and tries to eliminate wood whenever possible without compromising structural integrity. All of these techniques, when properly executed, comply with the International Residential Code (IRC), but you should check local codes before beginning a project.
Accoya® Wood ，其耐久性和稳定性可媲美或超过最好的热带硬木。Accoya由快速生长的软木制成，于2008年被引入北美市场。用来制造阿科亚的过程被称为乙酰化，这一过程已经被研究了80多年。Accsys Technologies是Accoya木材的制造商，于2007年建成了生产工厂。< / p > < / div >
Structural Insulated Panels (SIPs) are prefabricated insulated structural elements for use in building walls, ceilings, floors, and roofs. They provide superior and uniform insulation compared to more traditional construction methods (stud or "stick frame"), offering energy savings of 12%–14%. When installed properly, SIPs also provide a more airtight dwelling, which makes a house more comfortable and quieter.
Parallel Strand timber是由长链木皮制成的，它们相互平行铺设并粘在一起。PSLs通常被安装在需要显著抗弯强度来支撑上方荷载的隐蔽墙空间中的柱、梁和柱头;然而，它们也可以作为一个暴露的完成材料安装有吸引力。< / p > < / div >
通常缠绕在一个结构外，由于要求的能量码，绝缘护套是流行的。绝缘护套是一个泡沫绝缘板降低能量消耗的材料。它没有任何结构能力，它需要额外的横向支撑来抵抗地震和风力荷载。绝缘护套的常见类型包括多异氰脲酸酯，模塑的膨胀聚苯乙烯和挤出的膨胀聚苯乙烯。
Wood Patio Decks是户外生活空间，建立在地上。虽然它们通常毗邻一个结构，例如房屋，但它们也可以作为木板走道构建或作为观察甲板的建筑物。木露台甲板的结构通常是框架与经过处理的木材。虽然一些不同类型的木材，包括软木，硬木，国内或热带木材，可以用于顶部表面甲板，每个都具有自身的优点和缺点。
Heavy timbers are a type of lumber that is differentiated from dimensional lumber by having minimum dimensions of 5 inches. Timber framing consists of joining heavy timbers together with pegged mortise and tenon joints, scarf joints or lap joints. Wood members of heavy timber framing are commonly known as post, beam, jetty, truss and brace. Historically, heavy timbers were hewn with axes or hand sawed. Today, CNC machines have modernized what was once a hand craft, allowing the industry to grow due to greater affordability of products and shorter lead.
结构面板是节能的，复合面板系统，是用于住宅和轻型商业结构的制造组件。Types include structural insulated panel systems (SIPs) or stressed skin panels and cementitious reinforced panels. Used on roofs, walls and floors, structural panels can reduce the time it would take to complete a building envelope with standard materials. Structural panels offer various R-Values, weather resistance, fire retardation, and has the ability to meet extreme structural requirements.
Mechanically graded lumber is lumber that has been tested and evaluated by a machine rather than by visual inspection. While most lumber is visually inspected and graded, machine grading is a more efficient volume service and creates cost-competitive products, while differentiating the higher strength lumber materials. It is commonly used to deliver materials for more demanding applications. Two types of machines are used to grade lumber, machine-stress rated (MSR) lumber and machine evaluated lumber (MEL) machines.
工程木材料是利用股，颗粒，纤维的产品，和木皮，以生产一系列不同类型的产品。Readily available at lumber yards, these products are cut to length in the field, similar to dimensional lumber. The application of engineered wood products is also similar to that of dimensional lumber; however, each offers its own performance and manufacturing advantages. Engineered wood products also have some disadvantages in comparison to dimensional lumber. They have less fire resistant, require more energy to manufacture, have adhesives that can potentially release toxins into the environment, and are prone to moisture damage. Engineered wood products are often used as columns, beams, girders, joists, purlins, rafters, studs and bracing.
