As we move further into 2025, it’s only natural to anticipate the trends that will shape the building envelope industry in the coming year. The push for high-performance homes continues to influence construction practices, with a strong focus on energy efficiency, durability, and resilience. Builders and homeowners alike are seeking innovative solutions to enhance the performance and longevity of their structures.

Here are five key trends one manufacturer predicts will define this year:

1. Enhanced Resilience Against Extreme Weather

With climate change driving an increase in wildfires, hurricanes, and severe storms, the demand for resilient building materials and techniques is stronger than ever. Builders are turning to fire-resistant cladding, decking, and roofing materials that meet Wildland Urban Interface compliance. High-wind-rated siding and roofing options are also gaining traction. Additionally, robust envelope designs that facilitate water drainage are essential for long-term performance. Self-adhered underlayments offer an added layer of protection in the event of shingle loss during storms.

2. A Systems-Based Approach to Energy Efficiency

As more jurisdictions adopt the 2021 International Residential Code, stricter energy efficiency requirements are becoming the norm. While past efforts to tighten home envelopes sometimes led to unintended moisture issues, builders are now taking a more holistic approach. Investing in weatherization solutions, HERS raters, and building science consultants is becoming standard practice. Computer modeling is also being leveraged to design high-efficiency envelopes that manage moisture effectively while maintaining superior indoor air quality.

3. Mandatory Rainscreens for Stone Veneer and Stucco

A significant update in the 2021 IRC mandates the use of rainscreens behind manufactured stone veneer and stucco claddings. These absorptive materials require a fully ventilated drying space to prevent moisture-related failures. By incorporating a ventilated rainscreen with openings at both the top and bottom of the wall, builders can create convective airflow that enhances drying and reduces the risk of water damage.

4. Expansion of Continuous Exterior Insulation

Continuous insulation is becoming a standard requirement in Climate Zones 4 and above, per the latest building codes. Adding CI to the exterior of the building envelope improves thermal performance by eliminating thermal bridging and increasing the structure’s overall R-value. However, this shift also requires careful consideration of how exterior foam board impacts the installation of weather resistive barriers and flashing to maintain effective water and air management.

5. Growing Adoption of Conditioned Attic Spaces

As energy efficiency continues to be a priority, conditioned attics are becoming more prevalent. However, improper design choices—such as insufficient vapor permeability and inadequate ventilation—can trap moisture, leading to condensation, mold growth, and premature roof failure. Using vapor-permeable underlayments can help facilitate moisture escape, ensuring a dry and durable building system.

By staying ahead of these trends, builders can ensure they are implementing best practices that enhance resilience, energy efficiency, and overall performance.
