About This Product

■Repeat rate over 80%. Quality that lasts for over 20 years, overturning conventional wisdom about waterproofing

A new quality that combines TPO and SBS and is resistant to both heat and cold. Long-term durable waterproof roofing material (torch method).

■Characteristics of Ramco Sheet DuO

・Does not shrink or cause cracks - Strong resistance to expansion and contraction in summer and winter ・Maintains flexibility even at low temperatures - Strong tear resistance even at low temperatures

■A waterproof sheet that is ideal for Japan's climate

Modified asphalt tarpaulin is an excellent tarpaulin introduced from Europe. TPO (APP) sheets, which are resistant to heat, and SBS sheets, which are resistant to cold, exist independently, but in regions like Japan, which have four seasons and large temperature differences, it is possible to combine the characteristics of the two sheets. This is an important point for durability. Ramco Sheet DuO is the only waterproof sheet that has made this possible.

■Amazing quality retention performance

We cut out sheets that had been installed for 10 years and asked a public institution to test them. As a result, we found that there was almost no deterioration due to age and that the sheets were durable for 20 to 30 years. *A part of the construction surface was cut out on the rooftop of the main building of Mitsubishi Electric Corporation Itami Works, and an aging performance deterioration test was conducted at SGS (Global Building Materials Testing Period) (test method: EN 12317-1).

■Responsible construction that takes full advantage of high quality

No matter how good the waterproof material is, construction technology plays an important role in waterproofing work. We have an independently trained construction team, and our highly experienced and skilled workers are engaged in construction work, and we are able to carry out construction work not only on flat land, but also on difficult-to-understand objects (around frames and pipes) without any problems. The basics of construction are groundwork preparation. Our experienced staff will accurately identify deteriorated areas and dangerous areas, and will take the best measures according to the situation.
