Right now, the roof of the building you’re in is probably a very dark color, if not altogether black. Changing that color to white could radically improve operating costs, reduce utility bills, benefit the surrounding environment, and help everyone in the immediate neighborhood feel a little cooler during warm-weather months. Properly installed coatings of an environmentally advanced white elastomeric will enable the roof to last far longer, too.
The benefits of elastomeric coatings are not limited to roofs. Cementitious wall coatings formulated with this tough 100 percent acrylic elastomeric technology remain flexible but retain their tensile strength to protect over a wide range of temperatures. Their flexibility and softness also provide excellent resistance to dirt pickup and prevent wind-driven rain and moisture from seeping into cracks and causing structural damage, even in humid, hurricane-prone regions. Elastomeric wall coatings keep homes in one piece – safe and dry.
“White Knights” to the Rescue
Reducing heat build-up on commercial and residential roofing can dramatically affect building operating costs. Findings reported by the Roofing Manufacturers Association conclude that heat build-up can shorten the useful life of rubber, synthetic polymer, and especially asphalt roofing systems. Cool roof technology utilizing specialized white coatings that reflect the sun’s light before it can be turned into heat significantly reduce temperature. For example, a 95° F day raises black roof top temperature to 170° F, while a white roof would not exceed 120° F — a temperature drop of almost 30%.

EPDM coatings are made up of elastomeric compound that is manufactured from ethylene, propylene, and a small amount of diene monomer. These ingredients are synthesized to produce a product that exhibits a high degree of ozone, ultraviolet, weathering and abrasion resistance, and outstanding low temperature flexibility and due to which best suits for roof leaks repair and roof leaks coatings. These ingredients also contribute to resistance to acids, alkalis, and oxygenated solvents (i.e., ketones, esters, and alcohols). The EPDM single-ply rubber roofing coatings have been an appealing choice for roof leaks repair for residential roofing and commercial roofing industry for over 40 years.
- The number one roofing choice of architects, roof consultants and contractors for both new construction and replacement roofing projects according to Building Design and Construction magazine and the National Roofing Contractors Association (NRCA) 2002-2003 market surveys.
- Over 1 billion square feet of new roof coverings in the United States annually.
- More than 500,000 warranted roof installations on 20 billion-plus square feet.
With wide widths and fewer seams, EPDM coatings improve contractor efficiency during installation. EPDM coatings offer a quick, clean, inexpensive solution able to be installed in a wide range of temperatures. EPDM coatings provide excellent UV and weather resistance as well as sheet flexibility and high elongation. Systems can be installed fully adhered, mechanically fastened or ballasted. A complete line of accessories, sealants and adhesives is also available.
Liners are the most cost effective method of making a waterproof pool in your garden, but what is there really to choose between all the makes and materials? Peter May tells you how you can make it neat or natural and also introduces the new Greenseal liner from Gordon Low.
Don’t you hate all those fancy scientific names and acronyms; those strings of letters that only mean anything to ‘them that’s in the know’. Somehow you feel excluded from all the information. But then again all you are Putting in preformed or rigid ponds can be pretty easy. Getting the level right can be the difficult bit.Putting in preformed or rigid ponds can be pretty easy. Getting the level right can be the difficult bit. after is to make a hole in the ground waterproof.
You have already vaguely contemplated going ‘au naturelle’ by puddling it in clay, but then there is all that mess. And then you thought of manufacturing the pool itself in concrete, but a few sums quickly made you realise not only the muck and disruption involved but also the expense. So then you continue your investigations down the aquatic centre and find a huge range of products that all have different names but all look pretty much the same: black, some are shiny, some are not. Admittedly some are rigid and already pool shaped. They will tell you these are made from are generally HDPE (High Density Polyethylene) or ABS (Acrylonitrile Butadiene Styrene) and those are also fiberglass – mostly bigger heavier pools.
Others liners look like sheets of plastic, whilst some look like rubber. And its here you discover all these exotic names like Pondalene, Aqualast, Maxipool, Alfafol and now everyone is talking about Greenseal – now what’s that?
Despite the variety of brand names most of the liners available are one of several quite distinctly different materials that will all do the same job, and as individual materials they only come from 2 and 3 factories around the world. So it is highly likely that products, or at least the raw materials, with similar specifications will have come from those same factories in America, Belgium or Sweden.
The flexible sheets of material are either PVC (Polyvinyl Chloride) or Polyethylene – those are the shiny ones – and matt coloured ones are EPDM rubber (Ethylene Propylene Diene Monomar) or Butyl rubber. Well as your eyes are glazing over and you feel no wiser, you still aren’t finding the choice any easier. Once upon a time that choice was much easier.
