13 June 2005The Comrades Marathon has honoured the “forgotten heroes” of the world-famous ultra-marathon – hundreds of black runners and women who had to run the race “unofficially” prior to 1975, when it became SA’s first major sporting event to open to people regardless of race or gender.Up until that time, Natal and South African Athletic Association rules prohibited women competing with men, and – except with government approval – black people competing with white.The Comrades Marathon Association (CMA) held a civic reception outside their offices in Pietermaritzburg on 10 June to honour the “forgotten Comrades” – chief among them being Robert Mtshali, who in 1935 became the first black runner to attempt, and complete, the gruelling ultra-marathon.CMA acting CEO Cheryl Winn, speaking ahead of the event, said: “We are going to honour all those who missed out.“Seventy years have passed since Robert Mtshali became the first black man to ‘unofficially’ complete the Comrades Marathon, and we’ve commissioned a bronze memorial to commemorate his run, which will permanently occupy pride of place at the entrance of our Comrades Museum.”The museum’s Forgotten Comrades exhibition, also opened on 10 June, focuses on the many men and women who ran the race unofficially before 1975.Even when the race opened up in 1975, the field was limited to just 1 500 runners, and runners had to prove their qualifying times. That meant that many potential competitors were excluded.After cutting the field down from the 1 686 entrants to the allowed 1 500, only 18 non-white runners and two women were included in the field in 1975.First black winnerThe first black runner to win an official Comrades Marathon medal was Vincent Rakabele, who finished in 20th place in 1975 in a time of six hours and 27 minutes. Rakabele went on to finish fourth in 1976 and eighth in 1977.However, it was a long wait for the first black winner of the event. That honour went to Sam Tshabalala in 1989, when he won the down run in 5:35:51.Sadly, Tshabalala was badly injured in a motor accident in 1991. Only after a courageous battle did he make his comeback in 1992, claiming a silver medal. He has since claimed a further three silvers, and in 1998 was recognised for his contribution to the famous race when he was awarded the prestigious Platinum medal.Jetman Msutu became the second black winner in 1992 when he was promoted to first place after Charl Mattheus was disqualified.Maybe the most recognised and loved black contender never won the race. Hoseah Tjale had the misfortune that his career coincided with that of the legendary Bruce Fordyce. While Fordyce racked up the wins, “Hoss” was consistently among the great men’s challengers, twice finishing second and twice claiming third with his awkward, shambling running style.By the end of his Comrades career, Tjale had won nine gold medals and four silvers.The first woman to complete the Comrades – in an unofficial run – was Frances Hayward in 1923. She took 11 hours, 35 minutes and 28 seconds to complete the distance, which was good for 28th place.Geraldine Watson became the first woman to complete both an up and a down run, first doing the Pietermaritzburg to Durban race in 1931, and then the Durban to Pietermaritzburg run in 1932.Today, the trophy that goes to the last runner to finish is named after Watson.SouthAfrica.info reporter Want to use this article in your publication or on your website?See: Using SAinfo material
Insulating Low-Slope Residential RoofsGreen Basics: Insulation ChoicesGreen Basics: RoofsSpraying Polyurethane Foam Over an Existing Roof Roofing With Foam From Building Science Corp.: Moisture-Safe Unvented Wood Roof Systems Combine blown fiber insulation with rigid insulation“In Atlanta even an inch or two of exterior rigid polyiso or 3 in. of rigid high-density rigid rock wool panels would be enough dew point control to allow you to blow the joists full of cellulose,” Dana Dorsett replies. “Alternatively, 2 in. of closed cell foam on the underside of the roof deck would be sufficiently protective to fill the rest with blown fiberglass.”Only one of West’s four options makes sense to Dana Dorsett, and that’s a slightly modified No. 4.Instead of using rigid extruded polystyrene insulation, however, Dorsett suggests polyisocyanurate, a greener choice, or 2 in. of closed-cell polyurethane foam with the rest of the roof cavity filled with cellulose. Spray foam roofing could even be used on the top of the roof deck as long as it was finished with a UV-resistant coating. That, Dorsett says, would some money in upfront costs and eventual roofing replacement costs. “Mopping on new UV-resistant goop every 15-25 years is a lot easier and cheaper than re-roofing with membranes or composite asphalt solutions,” he says. (For more information on the use of spray foam as roofing, see Spraying Polyurethane Foam Over an Existing Roof and Roofing With Foam.)Dorsett would avoid all of the other options, either because they use batt insulation or because of the global warming potential of the XPS foam. Our expert’s opinionWe have comments from two experts, GBA technical director Peter Yost and also Brett Dillon, managing director of IBS Advisors of San Antonio, Texas.First, Peter Yost:I hate to draw this line in the sand, but I have just seen too many air leaks and related moisture problems with can lights in unvented roof assemblies: if you must have them, install them in a dropped soffit or ceiling so that the cans and all wiring are NOT within the roof assembly proper.Atlanta is a real challenge: significant moisture drive during both heating and cooling seasons, and what I recall as an average of 54 inches of rain annually. Better get those unvented roof assemblies details right.I asked Brett Dillon to weigh in on this question for three reasons: he knows his building science cold, he works in lots of different climates, and — being from the Southwest — he deals with flat roofs all the time.Here’s Brett:Here’s what I have from an architect friend in the Atlanta area, including construction cost to frame the roof:Built-up roof, $6-$11 per s.f.Single-ply membrane, $7-$11 per s.f.Closed-cell spray polyurethane roofing foam, 1.5 to 2 in. thick, $6-$12 per s.f.Standing seam metal roof, $9-$15 per s.f.Vegetated roof system with growing medium and root barrier, $110-$120 per s.f.These roofing materials are approved for a 1/4:12 (2%) slope. Asphalt roll roofing isn’t supposed to go on anything with less than 1:12 slope, so I didn’t include it.I’ll be honest — I think low-slope roofs are a really bad idea in the Southeast where we get huge amounts of rain at once, especially Atlanta. I’ve worked on projects that have used the built-up roof, single-ply membrane, and the vegetated roof systems. They all had failures within four years.The vegetated roof system had to be re-engineered during design to support the weight of saturated growing medium plus plants and furniture. That added to the cost, plus it had open-cell spray foam under the deck, tapered polyisocyanurate foam board above the deck, a single-ply membrane, a root barrier, growing medium and furniture platforms, and plants. It still leaked over time.Nothing fixes a flat roof like making it a 2:12 slope! And then there’s this whole flat roof thingTo James Morgan, the central question is why use a flat roof in the first place. It may be nothing more than architectural artifice.“In 1933 a group of European architects took a cruise around the Mediterranean and decided the whitewashed flat-roofed parapet-walled village buildings they saw there should be the model for a ‘rational’ style of architecture applicable anywhere, in any climate and in any culture, whatever local indigenous, traditional building wisdom may tell us to the contrary,” Morgan writes. “We have suffered the consequences ever since.“Which is my way of saying, why not put a ‘real’ roof on your projects?” he continues. Morgan suggests a roof with “climate-appropriate overhangs and roof pitches designed to actually and reliably protect the vulnerable structure below. Oh, and by the way, there are many better ways to light artwork than ceiling cans. As any decent contemporary art gallery can attest.”“Does holding up a few bad examples justify maligning an entire genre of architecture?” West replies. “One can find examples of bad design and lack of appropriate maintenance across all periods and styles. I’m sure I could send you dozens of photographs of the same issues with traditional homes. Once you go over one-story in height, most normally sized overhangs don’t provide that much protection to the lower floors anyway. How often does the rain fall perfectly vertically?” Among West’s questions are:What option provides the best R-value for the money?Does the use of closed-cell spray foam under the roof sheathing make it harder to track leaks in the future?“Any help in assessing these options and especially in comparing real-world costs wold be greatly appreciated,” West writes. That’s the topic for this Q&A Spotlight. First, lose the can lightsWhat jumps out at GBA senior editor Martin Holladay first is West’s use of recessed lighting in the ceiling below the roof deck.“It’s too bad that you (as an architect) don’t have the ability — either the persuasive power or the judgment — to insist that an insulated ceiling have zero recessed can lights,” Holladay says. “If the can lights are there, it clearly makes no sense whatsoever to depend on fluffy insulation (either fiberglass or cellulose) sitting on top of the ceiling drywall. All of those options should be taken off the table.”What’s left, he adds, are using spray-foam insulation on the underside of the roof sheathing or rigid foam on top of the roof sheathing. Holladay informed West that these options were discussed in a recent GBA article, Insulating Low-Slope Residential Roofs.West is aware of the energy shortcomings of recessed lighting fixtures, but they seem to come with the territory, he tells Holladay.“I try to limit the number of recessed cans as much as possible and use many fewer than most architects I know,” he says, “but the reality is that people that want a modern home tend to also value having wall art and they want to light it appropriately and there’s no other decent/affordable way to do that except with recessed can products.”Besides, he adds, most of the scenarios he proposes include spray-foam insulation on the underside of the roof sheathing, an air and thermal barrier that would not be compromised by the light fixtures. RELATED ARTICLES Most of the houses that Atlanta architect Scott West designs are contemporary, and they typically come with flat roofs. Construction often consists of 12-in. deep I-joists or open-web 2×4 trusses capped with oriented strand board (OSB) sheathing. Roofs are unvented, and the use of recessed can lights is probably unavoidable.The most common options for insulating these roofs, West writes in a post at GreenBuildingAdvisor’s Q&A forum, would include:Over the roof sheathing, add an additional layer of OSB installed on tapered 2x furring strips to slope the surface of the roof to drains, and then insulate with R-30 fiberglass batts between the rafters. “Not particularly smart or green in any way,” he says, “and requires extensive air-sealing, but as with most things, the most-common way is most affordable.”Place 4 in. of XPS rigid insulation on top of the deck and 4 in. of closed-cell foam on the underside of the deck for a total R-value of about 44.Place 4 in. of XPS rigid insulation on top of the decking, 2 in. of closed cell foam under the deck as an air barrier and then add R-30 batts for a total R-value of about 62.Skip the XPS above the deck and use sloped decking as in the first option, then use 2 in. of closed-cell foam and fill out the remaining 10 in. of the roof cavity with dense-packed cellulose for a total R-value of about 47.
