Creating Ventilation with Enertite Open Cell Foam

When it comes to creating energy-efficient, well-ventilated spaces, achieving the right balance between insulation and airflow is crucial. At Alpha Insulation Limited, we specialize in providing top-quality insulation solutions that ensure both effective thermal protection and optimal ventilation. One of our most trusted methods is the installation of open-cell foam with a vent card, creating a consistent 50mm air gap for improved airflow and moisture management.



In this post, we’ll explain how this innovative approach works and why it’s an ideal choice for homeowners and businesses looking to enhance energy efficiency while preventing moisture build up.


Open-cell foam is an excellent insulation material, known for its ability to expand and fill gaps, creating an airtight seal that helps prevent heat loss and reduce energy bills. Unlike closed-cell foam, open-cell foam is breathable, allowing air to pass through. This makes it an ideal choice for applications where both insulation and ventilation are needed.


By combining open-cell foam with a 50mm air gap, we can provide superior insulation while maintaining the necessary airflow to prevent moisture accumulation and ensure the long-term health of the building. This method is particularly effective in attics, walls, and ceilings where ventilation is often overlooked.


The Benefits of Installing Open-Cell Foam with a 50mm Air Gap

1. Enhanced Energy Efficiency

The primary benefit of open-cell foam is its ability to create a barrier that prevents heat from escaping, reducing the overall energy required to heat or cool your space. By maintaining a 50mm air gap, we ensure that your insulation works at its full potential without compromising airflow.


2. Improved Ventilation

Proper ventilation is essential to prevent moisture build-up, which can lead to mould growth, wood rot, and other structural issues. The 50mm air gap provides adequate airflow behind the insulation, ensuring that any moisture that may accumulate is able to escape, keeping your space dry and healthy.


3. Moisture Control

Without proper ventilation, moisture can get trapped in poorly insulated areas, leading to mould and mildew problems. Our method ensures that your home or building remains dry by allowing air to circulate freely, even in tightly insulated spaces.


4. Cost-Effective Solution

This approach is a cost-effective way to provide both insulation and ventilation without the need for additional, expensive ventilation systems. The open-cell foam itself acts as an excellent thermal barrier, while the spacer cards provide the necessary gap for airflow.


5. Long-Term Durability

By combining high-quality open-cell foam with a carefully maintained air gap, you create a durable, long-lasting insulation system that continues to perform well for years. This not only protects your investment but also helps maintain the integrity of your building.


How We Install Open-Cell Foam with a 50mm Air Gap

At Alpha Insulation Limited, our installation process is designed to ensure the highest quality results for your home or business. Here’s an overview of how we approach each project:


1. Site Assessment and Preparation

Our team will begin by assessing the area to determine the suitability and best approach for insulation. We’ll ensure that the surface is clean and ready for installation, addressing any existing moisture issues that could affect the foam's performance.


We place vent cards at consistent intervals along the area to be insulated. These cards maintain a precise 50mm gap between the foam and the surface, ensuring proper ventilation while maximizing insulation.


3. Application of Open-Cell Foam

Once the vent cards are in place, we apply high-quality open-cell foam, ensuring it fills the space efficiently without disrupting the air gap. The foam expands to create an airtight seal, providing excellent thermal resistance while allowing for airflow behind it.


4. Final Inspection and Adjustments

After the foam is applied, we conduct a thorough inspection to ensure the air gap is maintained and that there are no areas where foam has overflowed or created a blockage. We make any necessary adjustments to ensure a perfect installation.


5. Curing and Post-Installation Checks

The foam is left to cure and expand to its full capacity. Once the curing process is complete, we perform a final inspection to ensure the foam has adhered properly and the installation is both functional and durable.


6.Liaising with Building Control and Providing Certification

We understand that insulation projects often require compliance with local building regulations and codes. Our team is experienced in working closely with building control authorities to ensure that all installations meet the necessary standards. We handle the required documentation and certifications, giving you peace of mind that your insulation is both effective and compliant. Whether you're working on a residential project or a commercial build, we can guide you through the process and provide you with the relevant certification upon completion, ensuring that your insulation installation meets all legal and safety requirements.
