Sealco Waterproofing are proud to be the first in the market with our EcoTUFF TPO membranes.
Introduced to NZ in 2004, EcoTUFF has gained much popularity in the New Zealand market mainly due to the quality, price and added features. EcoTUFF TPO thermoplastic polyolefin membrane is a co-polymer of polypropylene and ethylene propylene rubber that has been formed into a membrane sheet and reinforced with a heavy duty polyester scrim. This means you get a flexible rubberised material with the ability to be heat welded for permanent secure detailing.
EcoTUFF Is manufactured by the largest and most technically advanced manufacturer in the USA and is well known internationally to be one of the best performing membranes available. It is BRANZ Appraised and comes with a full system of heat welded accessories to ensure watertightness in all areas of your roof. EcoTUFF provides absolute watertight integrity for low-slope and pitched roofs, gutters, parapets, pond liners, balconies, under floating decks and roof gardens of commercial and residential buildings.
A ‘second generation’ single ply product, EcoTUFF marries the advantages of previous generation materials while eliminating their limitations. The result is a roofing membrane that is faster and easier to install yet offers outstanding resistance to weathering, temperature extremes, ultraviolet exposure and a whole wide variety of industrial chemicals.
Tegosolar® is a photovoltaic shingle with the advantages of normal shingles, with which it integrates perfectly. Tegosolar offers high architectural standards in many settings where it would be “impossible” to fit traditional photovoltaic panels.
Tegosolar®’s various traits – namely its slim design, flexibility and light weight – make it a winning choice for many roof types, both on new builds and renovations, on buildings for residential, commercial and public use, as well as on industrial buildings.
The Tegosolar® photovoltaic cells are made of triple-junction thin-film amorphous silicon: each cell absorbs the blue, green and red light in the solar spectrum through its 3 separate layers.
In this way, the PV cells convert a broader spectrum of light into electricity than traditional modules, as they produce energy with direct light as well as in diffused light conditions, namely when the sun is low, when the sky is cloudy and when cells are installed where orientation and angle are less than optimal.
Bypass diodes between the cells allow the module to produce energy even when it is partially in the shade, unlike traditional modules that would lose power from all cells connected in series, and not just from the cell affected by shade. They offer excellent performance at high temperatures, a quality that makes them particularly suitable for roof-mounted applications. They do not require rear ventilation. They have a greater output in kWh of electricity produced per installed Watt (up to 20% more) than many other types of PV module on the market. When they reach the end of their service life, modules are easy to dispose of thanks to the PV Cycle scheme.
