APRIL 17, 2025- Sika is generating growth in Q1 despite unpredictable markets and continues investing worldwide

In the first quarter of the 2025 financial year Sika has continued to grow, despite less predictable global trade and ongoing geopolitical tensions. In markets in which protectionist tariffs are hindering free trade, Sika’s local supply chain and its systematic global production expansion over the past years are proving to be a strategic advantage. With over 400 factories worldwide, the company has a comprehensive production network in 102 countries and produces its state-of-the-art technologies locally. Sika is therefore not directly affected by tariffs and can reliably supply its customers even under challenging market conditions as well as continue to strengthen its leading position in the field of construction chemicals by gaining market share.

APRIL 10, 2025 - EV40 vs EV20 – Meet the "EV Twins" of Vapor Intrusion Mitigation

What Are EV40 and EV20?Geo-Seal EV40: A high-performance vapor barrier, featuring an EVOH membrane (Ethylene Vinyl Alcohol) reinforced with a durable geotextile layer. This combination creates a single-sheet barrier that is chemically resistant, easy to install, and offers additional built-in protection when placed over gravel substrates. The thicker 40 mil membrane makes EV40 an ideal solution for sites requiring extra defense against vapor intrusion.Geo-Seal EV20: EV20 is also made with the same EVOH membrane, yet with a slightly thinner 20 mil barrier. While it is equally reliable in protecting against vapor intrusion, it is best suited for projects preemptively mitigating their risk or active subslab depressurization (SSD) systems. EV20 enhances the efficiency of these active systems, helping to optimize overall vapor mitigation.

Common Air Barrier Tests

Air barrier tests are important because they can identify air leaks in the building envelope, which can lead to energy loss and indoor air quality issues. By identifying and sealing these leaks, the energy efficiency of the building can be improved, and the indoor air quality can be enhanced.

The responsibility for conducting air barrier tests on a building envelope typically falls on the building envelope consultant or the building owner. The building envelope consultant typically designs and specifies the air barrier system and is responsible for ensuring that it is installed correctly and performs as intended. The building owner is responsible for ensuring that the building envelope is constructed in accordance with the design specifications and that it meets the relevant building codes and standards. In some cases, a third-party testing agency may be hired to conduct the air barrier tests.

The experts at Carlisle Coatings & Waterproofing have provided a list of testing and diagnostic evaluations that consultants and testing agencies often perform. A description of each is provided, along with the purpose and precautions. Though this list is not exhaustive, it incorporates the most common testing.

Flowfresh is introducing new packaging with paper bags and plastic linings, featuring a refreshed design and detailed product descriptions for better identification and information. This change responds to customer feedback about the high cost of disposing wooden crates, leading to the adoption of more cost-effective pallets. Pallets reduce wood usage, improve handling, and allow more efficient loading, which boosts shipping capacity, cuts costs, and lowers the carbon footprint. The switch aligns with sustainability goals and customer needs. Additionally, Flowfresh is incorporating automation in production with a new bagging system, ensuring faster order fulfillment and the ability to meet growing regional demand. This packaging update reflects Flowfresh’s commitment to sustainability while maintaining high service and quality standards.
