Insulation Baffles | Insulation Baffle

Proper attic ventilation is crucial for a healthy and energy-efficient home, and insulation baffles are the unsung heroes of the process. At Insulation4US, we stock a reliable range of insulation baffles designed to prevent airflow blockages while maintaining the effectiveness of your attic insulation.

What Are Insulation Baffles?

Insulation baffles, also known as attic rafter vents or vent chutes, are lightweight panels that create a channel for air to flow from the soffit vents into your attic space. Installed between rafters, they ensure that insulation doesn’t block the crucial airflow needed to regulate attic temperature and reduce moisture build-up.

The 3 in 1 Cardboard Ventilation Draft Stop Soffit Baffle (Bafflo) is a smart, eco-friendly solution designed to maintain proper attic airflow, prevent insulation blockages, and reduce wind-driven insulation movement. Made from durable corrugated cardboard, Bafflo combines three functions in one: it acts as a ventilation channel, a draft stop, and a clean insulation barrier—all in a lightweight, easy-to-install format. Perfect for use with both blown-in and batt insulation, it fits neatly between rafters to create a clear path for air from soffit vents while holding insulation securely in place. Ideal for both new builds and retrofit applications, this cost-effective baffle is a favourite among contractors and DIYers alike looking to boost energy efficiency and moisture control in the attic.

Why Use Insulation Baffles in Homes?

• Preserve Attic Ventilation – Baffles ensure continuous airflow, which helps prevent condensation and mould.
• Protect Your Insulation Investment – Without baffles, insulation may sag into soffits, reducing thermal performance. Baffles hold it in place and optimise energy savings.
• Simple to Install – Lightweight and durable, our baffles can be easily installed during new builds or retrofits.
• Compatible with All Insulation Types – Whether you're using batt insulation or blown-in insulation, these baffles work perfectly alongside them.

Benefits of Insulation Baffles

• Improved Attic Ventilation – Prevents insulation from blocking soffit vents, allowing fresh air to circulate and remove heat and moisture.
• Moisture Control – Reduces the risk of mould, mildew, and condensation in the attic.
• Energy Efficiency – Supports consistent airflow, improving insulation performance and lowering heating and cooling costs.
• Extended Roof Life – Helps minimise the chances of ice damming and overheating under the roof deck.

Applications of Insulation Baffles

Insulation baffles are ideal for:

• Residential attics – Especially those using blown-in or batt insulation.
• New construction – Ensures proper airflow setup right from the beginning.
