Moisture-permeable and waterproof sheet with 'air tightness' proposed by DuPont headquarters in the United States!
"Weathermate Plus" solves the problem of deterioration caused by heat and ultraviolet rays that is pointed out in breathable waterproof sheets, and it does not lose its waterproofing even when insecticide agents adhere to it. ■Improved airtight performance The windproof performance of Weathermate Plus is 40 times that of standard waterproof paper. It is a breathable, waterproof, and airtight sheet that enhances airtightness by preventing air passage. ■UV resistance and insecticide resistance It is strong against ultraviolet rays, with a UV resistance guarantee of 120 days, which is twice that of standard waterproof paper. It does not lose its waterproofing even when insecticide agents adhere to it. ■Prevention of convective heat transfer The base fabric of Weathermate Plus absorbs the warm or cold air that circulates within the ventilation layer, reducing heat transfer to structural materials. ■Weather resistance and heat strength It is heat-resistant, with tensile strength and other material strengths that are twice that of standard breathable waterproof paper. ■Improved waterproofing Rainwater that enters through the staple holes used to secure the waterproof paper or the nails used to secure the battens is absorbed like a diaper without dripping on the backside of the waterproof paper. Please use recommended waterproof tape around windows and piping. *For more details, please download the PDF or feel free to contact us.
