This Awkward Passivhaus design barrel roof made airtight with ease with Spray applied Airtight vapour control membrane Passive Purple.

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.

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.

We built the world first Passivhaus CPD training facility / pub, this is the worlds most airtight pub at 0.07ach at 50 pa. This is a twin wall timber frame, it’s 450mm wide insulation Huntsman which is made of thousands of recycled plastic bottles. Huntsman also recycled 1 billion plastic bottles from the sea last year. We have a 7.2 KW system solar panels system that powers the building, it’s got MVHR Nilan. On the external façade we applied Passive Purple External which is airtight up to 0.03ach.

This is a case study of a drop-down ceiling area in a large hospital. This area was sprayed with Passive Purple along all the ceiling joints and 1 and half meters around the opening of the building on all external facades. This project was actually a retrofit with an original air test score of 7. After the application of Passive Purple the score was down to 0.6.

Faced with a tight schedule and challenging weather conditions, Belluz Group Ltd. turned to MAPEI for the range of high-end products and support that was needed to complete a new-build terminal project in the heart of Canada’s biggest city.

Introduction Sheet steel roofing and siding (cladding) is available in a wide variety of profiles, colours and paint systems. The modern prepainted systems used on Canadian-made products will provide decades of beautiful performance before there are any visible signs of deterioration of the paint surface. However, an important component of the cladding system is the fastener used to attach it to the structure. This fastener is not simply a screw; it is part of the roof or wall assembly and should be expected to provide the same long-term performance. This performance is not simply the capacity to safely hold the cladding in place, but also to match the colour and durability of the paint system. The selection of the correct screw for the job is the first step in the creation of a cladding system that will provide long-term performance. The next step is the installation. Installing screws in sheet steel cladding is commonplace and can be done very efficiently. The tool manufacturers have developed a wide range of options for installing fasteners into any type of substrate. Selecting the most appropriate tool will help the installation process.

Introduction Prefinished sheet steel building products, such as wall and roof cladding, liner sheet, flashing, and associated items, have experienced an enviable growth record during the past twenty years or so. Coil coated prefinished sheet steel in a variety of colours and paint systems has greatly enhanced the appearance of thousands of industrial, commercial, institutional, recreational, residential and farm buildings, providing an economical, durable and attractive alternative to traditional materials. As with all materials, a little care and maintenance pays off handsomely in terms of longevity and repair costs. The recommendations which follow have been learned at first hand and represent the collective industry experience with thin-film paint systems applied to metallic coated sheet steel by the coil coating process. In this publication the term “thin-film paint system” refers to a modified silicone polyester or a fluorocarbon type having a coating thickness about 25µm. When the guidelines listed below have been observed, thin-film paint systems have been used successfully for all types of environments other than severe industrial atmospheres which require special consideration. The guidelines are not intended for barrier coatings, laminates, and new formulations which have different characteristics than the thin-film paint systems on which these guidelines are predicated. 

For BART's Doolittle Maintenance Facility at the new Oakland Airport connector, SAFTI FIRST® provided 60 minute, fire resistive wall openings in the exterior using SuperLite® II-XL 60 insulated with low-e glazing in GPX® Framing with a clear anodized finish. SAFTI FIRST® engineered a connection that allows the structural elements of the GPX® Architectural Series Framing System to support an integral sunshade system, instead of being hung in front of it. The Doolittle Bart Station is one of the first installations of the GPX® Architectural Series System with sunshade connections, which also include SLCC New Instruction and Administrative Building in Salt Lake City, UT.

This Fact Sheet has been written to describe some of the factors that affect the cost of prepainted sheet steel cladding products. The most significant factors are: colour, paint system, order quantity, Fabricator's inventory and profile selection. Recognition of the impact of these factors can help you select a prepainted sheet steel cladding system to fit the aesthetic and durability requirements of your project, and still stay within a budget. 

The 1890s-era Midtown Community Court in New York City—a New York Historic Landmark—is currently undergoing a five year, $18 million renovation that includes a 9,650-square-foot addition for a new elevator, lobby and stairwell featuring fire resistive glass and curtain wall. The system consists of SAFTI FIRST®’s SuperLite® II-XL 120 IGU in GPX® Curtain Wall System.

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.

An independent assessment of the life cycle cost for various low slope roof systems revealed that steel roofing had the longest life span, no leaks due to material failures, and the lowest overall maintenance cost.

1. SCOPE 1.1 The following specifications shall apply to hot-dipped metallic-coated sheet steel prefinished with colours of proven durability and suitable for exterior exposure as delivered from the coil coater. Proven paint systems for building products have been designed for vertical applications whose surfaces are no more than 30° to the vertical and non-vertical applications whose surfaces ranging from 5° up to 60° to the horizontal. It is not recommended for aggressive atmospheric exposure. 1.2 The prefinish system shall consist of a primer and topcoat continuously applied and cured within the paint manufacturer’s specifications on cleaned, pretreated, metallic-coated substrate. The pretreatment specified shall be zinc phosphate for galvanized steel and metal oxide pretreatment for aluminum-zinc alloy-coated steel, applied in accordance with the pretreatment manufacturer’s specifications.

This new 120,000 square foot, state-of-the-art convening center features a 1,000-seat auditorium that is large enough to host the entire MBA class. The glass atrium floods the multi-purpose lobby with natural light, as well as provides a visual connection between the interior of the building and the outdoor environment. To maximize transparency, SAFTI FIRST® met with the architects during the design phase to create a large, 2-hour, glass wall that separates the lobby from the auditorium while providing a visual connection between them. Since this 2-hour glass wall also serves as the entrance to the auditorium, deciding on a 90-minute door system was of upmost important. SAFTI FIRST®’s in-house engineering department provided design assistance, system details, engineering calculations and support from the planning phase all the way to the submittal process.
