  • BEST PRACTICES for STUCCO APPLICATIONS GUIDE Revised April 1, 2019
    LENEXA – BEST PRACTICES for STUCCO APPLICATIONS GUIDE Revised April 1, 2019 This document is provided through endorsement by the Johnson County Building Officials. General Exterior wall coverings, along with the roofing, flashings, windows and doors, are designed to provide a weather-resistive barrier that separates the interior of the structure from the elements. Low maintenance and attractive appearance are just two reasons why hard coat stucco has become so popular over the years. At the same time, the building industry has become aware of the need to protect the exterior wall sheathing from moisture damage. The walls shall be constructed so that water does not accumulate within the assembly. This means creating a water-resistive plane behind the exterior veneer that allows moisture that does get into the wall to drain down and out without coming in contact with the wood framing. Detailing around windows, doors and other penetrations in the envelope is equally important in protecting the wood frame structure behind the stucco from being damaged by water infiltration. Since the wall sheathing behind the stucco is the lateral load resisting system of the structure, in addition to the supporting surface for the exterior siding, it is important to see that continuous undetected penetrations of the siding by moisture do not create structural damage such as decay and corrosion or environmental damage which may cause health related problems such as the growth of mold and mildew. To this end, the removal of moisture that gets past the exterior envelope before it contacts the wood framing is the primary goal of the weather-resistive barrier and why it is critical that it be installed properly.

THE AMES FORESTER 17 Wood Waste as a Raw Material Lionel K. Arnold, Engineering Experiment Station It is estimated that the annual sawdust pile of the world would be several times as large as the largest skyscraper of New 'York. The sawclust is only about one-fifth of the total waste from the lumber industry. It is estimated that 62 per cent of each tree cut for lumber is wasted. This includes the limbs, top, and stump as well as the waste at the mill. From the sawlogs alone the waste is approximately 49 per cent. Unbreakable dolls and dynamite are only two of the many products made fl-om wood flour which is made from sawdust and other wood wastes. In spite of the immense quantities of sawdust and other wood wastes produced in the United States, we are importing in the neighborhood of 12 million pounds of wood flour every year at a cost of about 90 thousand dollars.

HISTORIC RESOURCE DESIGN GUIDELINES CHAPTER 2.1: WINDOWS CITY OF SANTA BARBARA CHApteR 2.1: WinDOWS INTRODUCTION Windows are one of the most visible, yet commonly under-appreci- ated components of older and historic homes and historic resources. Many historic structures in Santa Barbara have original wood win- dows that have lasted over a century. They may have intricate details that give depth, light, and shadow to a building’s façade. Original windows reflect the design intent for the building, including the period, regional style, and building techniques. In fact, many wood windows are considered hand-crafted pieces of art that are examples of exceptional craftsmanship and design. Windows give scale to a building and provide visual interest to the composition of individual façades, while distinct designs help de- fine many historic building styles. These openings define character through their material, profile, shape, size, configuration, and ar- rangement on the façade.

  • How to Install Cedar Siding
    Congratulations on your choice of Western Red Cedar siding. Western Red Cedar is one of the world’s premier quality woods noted for its appearance, durability, light weight, insulation value and dimensional stability. It will provide your home with character and a distinction that other sidings cannot match. Properly installed and finished, it will provide years of low INTRODUCTION maintenance performance. Before beginning your siding project read this brochure thoroughly – it contains useful information to ensure the siding is installed correctly and will perform as intended. This brochure is organized into three sections. Section I. Before You Start deals with numerous considerations which you should be aware of before you start installing Western Red Cedar Siding. Section II. Outlines proper installation techniques. Section III. Provides a list of industry best practices for Western Red Cedar siding installation. Note that these are general guidelines that are minimum standards to be followed with confidence in most areas. However, severe local climatic conditions such as extreme heat and dryness; high winds; seacoast exposure; and, areas with wide climatic swings may necessitate additional provisions for the installation of the siding. Your national and local building code requirements always supersede these instructions. A detailed siding installation DVD is available from the WRCLA. Call 1-866-778-9096 for a copy. 2 SECTION I BEFORE YOU START 1. INSPECT MATERIAL Always purchase recognized grades such as those from WRCLA members and ensure you understand the grade of material you’ve purchased. Grades are designed for specific appearances and uses. Before installing, be sure the siding you’ve selected meets your requirements.
