Tru-Seal Attic Hatch – The Only Hatch That Preserves Your Vapour Barrier.

Maintains your ceiling’s vapour barrier, matches your attic’s insulation, and prevents unwanted air movement. Available in standard sizes or custom options for a perfect fit.

Tru-Seal Attic Hatch Features

Tru-Seal hatches are built different for better results. Rather than using a heavy insulated door that sits on a gasket and pushes into the attic to gain access, Tru-Seal is fastened on from underneath. This allows us to properly insulate the hatch and completely eliminates the risk of air flow into the attic.

Rubber Gasket Seal ensuring long-term air seal
High-Quality Rubber Gasket: Maintains a reliable air seal for years of use, even as it is compressed.
Fully insulated attic hatch cavity
Friction Fit Batt Insulation: Allows the access cavity to reach the same R-Value as the rest of the attic, improving energy performance.
Continuous vapour barrier preventing air leakage
Continuous Vapour Barrier: Tru-Seal maintains the vapour barrier to prevent air flow and moisture migration into the attic space.

Conventional Attic Hatch Flaws

Traditional attic hatches often create weak points in your insulation envelope — allowing air leakage, condensation, and thermal bridging that compromise your home’s efficiency.

Compressed Weather Stripping

Standard weather stripping compresses within a year or two, leading to poor seals and air gaps that allow unwanted airflow between conditioned and attic spaces.

Uninsulated Door Gap

The half-inch uninsulated space around the door — designed to allow the hatch to push into the attic — creates a cold bridge and allows air to meet at the faulty weather stripping.

Thermal Bridging

Conventional hatch designs create a direct conductive path for heat transfer — allowing indoor warmth to escape and cold air to infiltrate, lowering overall energy performance.

Why Choose Tru-Seal?

Purpose-built for performance and precision. Tru-Seal attic hatches are crafted to meet today’s building standards while making installation easier and results cleaner.

STANDARD OR CUSTOM FIT

Tru-Seal’s standard rough opening is 22½” × 26”, but custom sizes are also available with fast turnaround.

AIRTIGHT TO PREVENT HEAT LOSS

Fastening from underneath with a premium gasket ensures zero heat loss through the hatch.

SIMPLE TO INSTALL

Only a drill, batt insulation, and silicone are needed. Install in as little as 15 minutes.

PLACE THE HATCH ANYWHERE

By being fastened on from underneath, we are no longer restricted to attic height requirements as we are with the old wooden box hatches. As it is airtight, you can even install it in the laundry room!

CLEAN, MODERN APPEARANCE

Standard 2" PVC Brickmould frame, with an optional Shaker Panel frame available.

FLAME RESISTANT PANEL

PVC panels are flame resistant up to 10 mm thick—ideal for multi-unit applications.

The 4 Steps to achieving a proper performing hatch in your home:

Install cleats using silicone and supplied screws

Put the friction fit batt insulation in the cavity. We recommend R40

Install the PVC Seal Door Panel. This can be put on right after drywall and can remain on for the rest of the finishing as it will be covered.

Install the Decorative Finish Door. This is purely decorative and hides any scuffs that the Seal Door got during the finishing stages.

Installation Requirements

Simple steps for a clean, secure install and long-lasting performance.

Silicone Behind Cleats

Tru-Seal supplies PVC Cleats that are installed in the hatch cavity. (See photo). To properly ensure the hatch is installed air tight, please silicone behind the cleats when installing.

Friction Fit Batt Insulation

Because Tru-Seal is fastened on from underneath, the hatch can now be completely filled with friction fit batt insulation to the same R-Value as the rest of the attic! (Not Included)

R.O. Size Requirement

Tru-Seal is available in the standard R.O. size 22 1/2" x 26". Please contact us to order your custom size at no extra cost with a quick shipping turnaround to ensure you receive a hatch that works well for you!
