Repainting Factory Prefinished Metal Panels
Trimet Building Products
Introduction Prefinished sheet steel is used on many building products from wall cladding, to architectural roofing to interior panels. Prefinished sheet steel has been used in Canada for over 30 years and there may be sites were the paint surface is in need of repainting. This bulletin is intended to give some guidance on repainting prefinished panels. Due to the diversity of factory applied prefinished systems, and the diversity of potential field applied repaint systems, it is impossible to offer one comprehensive repaint procedure for all possible situations. However, it is possible to offer a set of guidelines to be considered in every potential situation.

Position Paper on Oil-Canning: Specifying Wide Flat Panels in Metal Cladding
Trimet Building Products
What is Oil-Canning? Oil-canning is associated with all thin sheet metal products and occurs in the wide flat portions of the cladding profile. It is seen as a series of standing waves, or regular bumps and hollows alternating along the flat length of the panel. This waviness, when viewed under certain conditions, can be undesirable aesthetically and may not meet with the owner’s expectations. The CSSBI wants to help avoid this situation. The cladding manufacturers are aware of the potential for oil-canning in the cladding profiles and can help minimize the effect. It is important for the proper steps to be taken during manufacturing and installation to produce a quality finished product; therefore, specifiers should insist on product from a reliable, experienced cladding manufacturer, like a CSSBI member company. Quality control, however, cannot end on the shop floor. The building project needs the cooperation and knowledge of everyone involved to enhance the quality of the finished job. Oil-canning is a phenomenon that can be managed if the following factors are considered at the beginning of a project.

Fire Rated Glazing Helps Achieve Unobstructed, Floor-to-Ceiling Views in 2-Hour Atrium Wall
SAFTI FIRST
There is a growing trend in office space design that favors increased opportunities for connectivity and collaboration among its occupants. In buildings with multiple floors, this can be a challenge as the vertical separation between floors makes face-to-face encounters less likely to happen. One way to get around this is by incorporating an atrium. See how fire rated glass helped the designers meet the fire rated requirements for this atrium while providing clear, unobstructed views.
Chicago Starbucks Reserve Turns Stair-Climbing Into Unforgettable Experience Using Fire Rated Glass
SAFTI FIRST
The Starbucks Reserve Roastery in Chicago features an incredible, 4-story mural by local artist Eulojio Ortega. The mural, brilliant for conveying the story as visitors go from floor to floor, is interestingly located in an exit stairwell. Traditionally, stairwells are enclosed in opaque walls, leaving them dark, isolated, and rarely utilized unless in an emergency. To allow the mural to be visible through multiple floors, encourage stair usage and meet fire rated code requirements, the architects redesigned the 2- hour stairwell using transparent, floor-to-ceiling butt-glazed glass walls with the largest tested and listed fire resistive glass panels available.

Residential Steel Roofing The Long Term Choice
Trimet Building Products
Steel has been used in North American construction projects for more than 150 years and still remains one of the strongest, most durable and economical building materials available today. Although steel has been traditionally associated with high-rise buildings, bridge structures and commercial and industrial projects, it is rapidly emerging as the logical material of choice for residential construction. Cold formed sheet steel panels are lightweight, economical, easy to handle and represent a high quality alternative to traditional roofing materials. Environmental and economic considerations have prompted many residential homeowners to investigate alternative building materials and methods, and steel roofing panels have proven technical benefits as well as excellent recycling capabilities which make them an increasingly popular choice. This follows the long-time use of steel roofing in commercial construction where steel has built undisputable quality and performance records.
Fire Rated Glass Brings Whimsical and Reliable Protection at Children’s Hospital
SAFTI FIRST
One of the highlights of the SUNY University Hospital’s vertical expansion is the addition of the Golisano Children’s Hospital on the top two floors of the six-story addition. Since the project added new floors, stairwell enclosures were also added. Traditionally, stairwells are relegated to the back of the building, and are usually closed-off, dimly lit and seldom used. Today, stairwells are becoming a prominent design feature and their use is encouraged more and more for the health benefits that stair climbing provides.

CSSBI SSF 19-05: Explosion Venting for Steel Frame Buildings
Trimet Building Products
Executive Summary The aim of this fact sheet is to advocate an alternative solution for the Steel Industry in regards to restrictive code provisions for explosion venting that are now mandated by the Ontario Fire Code (OFC). Due to a September 2000 amendment of code provisions dealing with explosion venting in the OFC, explosion vent designs were required to be in conformance with NFPA 68, the National Fire Protection Association’s (NFPA) Guide for Venting of Deflagrations. NFPA 68 gives a prescriptive solution that has upper bound limits on size and mass of an explosion vent panel, which the Steel Industry finds are too small to be practical. The Canadian Steel Construction Council (CSCC) investigated this problem and identified an alternate design guideline from the Factory Mutual Insurance Company’s (FM) Property Loss Prevention Data Sheets, numbered 1-44 and entitled “Damage Limiting Construction”. FM’s 1-44 Data Sheets can be used to develop an alternate solution for explosion venting that exceed the size and mass limits of the NFPA 68 prescriptive solution, and can be submitted for approval under the Compliance Equivalency provisions in the OFC. With the introduction of an objective based National Building Code Canada (NBCC) in 2005 followed by Provincial code adoptions in 2006 it would be worthwhile to establish a precedent through the Compliance Equivalency provision in the OFC. Once a precedent setting case occurs, the “acceptable solution” or “compliance alternative” would go on record and aid in resolving subsequent proposals for Compliance Equivalency, and also support a future technical change in the OFC. The CSCC by way of this fact sheet would advocate this alternative solution for the Steel Industry when designing explosion vent panels in steel framed buildings.
GT Yarmouth - Beattie passive - Retrofit
Intelligent Membranes Canada
An old block of apartments in Gt. Yarmouth getting a low carbon Retrofit for a higher, cleaner living standard and reduced energy bills. Passive Purple has been used externally on this huge scale block of apartments. with no margin for error and tricky details throughout, a liquid applied airtight membrane was the only way going forward. The building was being insulated externally and getting a whole new façade from render to aluminium panels. With the residents still inhabiting the building this had to be done quickly and easily with maximum results. Being a liquid applied airtight membrane, any cracks, gaps, and service penetration leaks in the existing building fabric quickly became thing of the past. That and the hundreds of Panel brackets being installed to support the new façade going on, this Retrofit had multiple penetrations and tricky details. Making good of the building fabric and awkward brackets with a near on impenetrable adhesion, Passive Purple made fast work of this great conversion, impossible for any other method. Being in liquid state on application, Passive Purple can be applied onto most/any surface (See data sheets for more information) and will find its way into all the unseeable tiny gaps and cracks all buildings will undoubtably have. Like this old pebble dashed façade, any rough, uneven and awkward areas are no longer an issue, our products simply flow into these areas. We also have the fibre reinforced Passive Purple brush, used on this job to prepare the brackets by filling the larger gaps between that of the bracket and the existing wall and also the large penetrating bolts. A huge win and demonstration of the power of liquid products by Intelligent Membranes.
San Diego Highrise Uses Fire Rated Glass on South Facade
SAFTI FIRST
Because the Sapphire Towers' south facing elevation was in close proximity to the adjacent property, code regulations required the south façade to either be solid, which was contrary to the design, or to have openings with a minimum fire protection of 45 minutes. SAFTI FIRST® engineered a system that met the uniform design demands and performance requirements for the windows and balconies in all 32 floors in the south-facing elevation.
CSSBI SSF 24-07: Natural Finish Metallic Coatings - Attractive but not Architectural
Trimet Building Products
Architects and Specification Writers are increasingly selecting unpainted metallic coated steels for architectural roofing and cladding applications on building exteriors where they want a “Silver” metallic finish. This is occurring more frequently, and even on “prestige” type projects. The Canadian Sheet Steel Building Institute whose fabricator members manufacture a wide variety of building panel profiles for roofing and cladding applications, are being asked to supply unpainted (natural finish) galvanized or resin coated 55% Aluminum-Zinc coated steel for these architecturally exposed end uses. Oftentimes, these materials are specified because the designer finds the natural finish of these products very appealing and sometimes because of material cost savings opportunities. This Fact Sheet has been developed to provide guidance in material selection and provide information on the Architectural Metallic Finishes that are available for highly visible steep slope roofing and cladding applications.
Boston Building Protects Property Line with Fire Resistive Curtain Wall

Orpington - Self Build - Timber and Masonry
Intelligent Membranes Canada
Renovation stripping out the building completely and rebuilding the walls, Passive Purple® was applied in between the connections of the internal side of the external walls which were a combination of masonry, timber, and steel frame. The ground floor ceiling was removed exposing the warped old timber joists with cracks in the surrounding brickwork and mortar. This was given attention to detail using Passive Purple® Brush to seal above an airtight foam to guarantee the airtightness of this major air leak zone before the final spray coat of Passive Purple® airtight membrane was applied. Passive Purple® was also used to seal window and door linings, ready for the new triple glazed windows to go in. Passive Purple® was sprayed on all the walls and ceiling. This is an ongoing project that still is awaiting an air test, the client is looking to hit 2.5 ach and installing MVHR.
