Helps Create a Water-Proof Barrier

Protects against water infiltration around eaves, rakes, valleys, vents, chimneys and skylights.

Overview

WeatherLock® Mat Self-Sealing Ice & Water Barrier is designed to act as an additional line of protection against damage due to shingle blow-offs, wind-driven rain and ice damming.

  • SureStep™ Technology provides excellent traction to help protect crews against slipping
  • Light weight - Easy to load, carry and install
  • Versatile selvage edge design - Allows for faster installation
WeatherLock® Mat Self-Sealing Ice & Water Barrier is an essential part of the Owens Corning® Total Protection Roofing System®^.

1. All values are approximate.

2. Sample modified as required to meet applicable test method.

3. XPS foam core values meet ASTM C578 TYPE IV.

4. k means the apparent thermal conductivity. The lower the value, the greater the insulation power.

5. Values at yield or 10% deflection, whichever occurs first.

6. Data ranges from 0.00 to value shown due to the level of precision of the test method.

7. Water vapor permeance decreases as thickness increases.

8. These laboratory tests are not intended to describe the hazard presented by this material under actual fire conditions.

9. Fire performance of FOAMULAR® 4" thick product only. Thicker products may have different fire performance characteristics. Due to limits on the equipment used to test per ASTM E84, Owens Corning® FOAMULAR® XPS Fabrication Billets have not been tested.

10. The surface burning characteristics of these products have been determined in accordance with ASTM E84. This standard should be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest 5 rating.

11. Limited to single layer application.

12. Preproduction qualification testing complete and on file. Chemical analysis of each production lot required for total conformance.

13. Includes core weight.

14. Limited to single layer applications above 650°F (343°C), but not greater than 6" (152mm) thickness.

15. With heat up schedule.

16. The surface burning characteristics of these products have been determined in accordance with UL 723, ASTM E84 or CAN/ULC-S102. Values are reported to the nearest 5 rating.

17. Preproduction qualification testing

18. Maximum allowable thickness at 1,000°F (538°C): Type I-HP - 8.5" (216mm); Type II-HP - 6"(152mm).

19. The surface burning characteristics of these products have been determined in accordance with UL 723, ASTM E84 or CAN/ULC-S102. These should be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest 5 rating.

20. Preproduction qualification testing complete and on file. Chemical analysis of each production lot testing required for total conformance.

21. Available on a regional basis.

22. The surface burning characteristics of these products have been determined in accordance with UL 723, ASTM E84 or CAN/ULC-S102. This standard should be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

23. Preproduction qualification testing complete and on file. Chemical analysis of each production lot required for total conformance.

24. The surface burning characteristics of these products have been determined in accordance with ASTM E84, UL 723, and CAN/ULC-S102. These standards should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions.
