Various towns in Oman
2017 : Roof Insulation on various Royal Oman Police stations, using a water-blown PU-Spray Foam. 68,000 m2 in total. 40-50 mm thick.
Product: Baymer SHPU-45W-35A / System Iso 44V20L
Benefit of System: HCFCs (R141b) are forbidden in Oman. The market has been converted years ago to water-blown systems as cost-efficient material with lowest GWP possible, and without any ODP.
Feedback on applicability: To be handled similarly to the old R141b-systems. Just density higher. If not sprayed carefully, bubbles could result.
