ENVIRONMENTAL PRODUCT DECLARATIONS

Environmental Product Declarations (EPD’s) are a third party verified document that discloses the environmental impact of a product or system while completing a Life Cycle Analysis (LCA). Creating an EPD is a completely voluntary process with two main options based on how much of the product's life-cycle a manufacturer chooses to disclose: “Cradle to Gate” and “Cradle to Grave.” “Cradle to Grave” discloses the full circle of a product’s life and is the more comprehensive of the two LCA’s.

The Sikalastic RoofPro products are the only liquid applied roofing and waterproofing systems to offer a fully disclosed “Cradle to Grave” EPD.  Sika is committed to constantly improving product lines to lower environmental impact and create safer products. 

In order to support comparative assertions, this EPD meets all comparability requirements stated in ISO 14025:2006. However, differences in certain assumptions, data quality, and variability between LCA data sets may still exist. As such, caution should be exercised when evaluating EPDs from different manufacturers or programs, as the EPD results may not be entirely comparable. Any EPD comparison shall be carried out at the building level per ISO 21930 guidelines. The results of this EPD reflect an average performance by the product and its actual impacts may vary on a case-to-case basis. Below are the available  EPD’s for Sikalastic-641 Lo-VOC and Sikalastic-644 Lo-VOC  Roofing and Waterproofing Systems. 

 

 LEED CONTRIBUTIONS

The use of Sikalastic RoofPro and RoofCoat products and accessories can add to a Building’s LEED® v4 credits and points. There are still many projects based on LEED 2009, but there is an increasing number of projects now requiring information based on LEED® v4. Projects seeking LEED® certification and registered after October 2016 require LEED® v4. 

There are up to four possible credits for the LEED® v4 rating system that applies to Sikalastic RoofPro and RoofCoat products and are addressed in the below letter. All information concerning LEED® credits was obtained from LEED v4 for BUILDING DESIGN AND CONSTRUCTION updated January 11, 2019. Always refer to the specific LEED® literature for details concerning credits and when they can be taken. As on all projects, LEED® v4 credits awarded for construction products should be reviewed, determined, and/or approved by the authorized LEED® Accredited Professional.

RECYCLED MATERIALS

Yellow Recycling Logo

Sika Fleece 120, 140, and 170 polyester reinforcing fabrics are made from recycled plastic bottles so you can feel good knowing the roof above your head is reinforced with environmentally friendly products. Sika Fleece reinforcement also strengthens roofs for longer-lasting performance with less maintenance. Roofing and waterproofing contractors choose Sika Fleece for wet-on-wet application of the base coat and topcoat in one shot – not only saving contractors time but also reducing costs and application materials used on each job site.

RoofPro Reinforcement

COOL ROOF INITIATIVE

 

 

All Sikalastic RoofPro and RoofCoat products come in a reflective white coating that reflects much of the sun’s light to cool buildings cooler and lower air conditioning costs.  In densely populated city areas this will also help reduce the “Heat Island” affect.  The US EPA defines the term "heat island" as “built up areas that are hotter than nearby rural areas” and explains: “The annual mean air temperature of a city with 1 million people or more can be 1.8–5.4°F (1–3°C) warmer than its surroundings. In the evening, the difference can be as high as 22°F (12°C).”
