Energy Efficient Properties of the Uni-T Mail Slot

The energy-efficient design of this mail slot incorporates advanced features to enhance insulation and prevent drafts. These thoughtful details ensure that the mail slot not only facilitates secure and efficient mail delivery but also plays a key role in maintaining optimal energy efficiency within the home.

Exterior Gasket and Torsion Rods

Torsion rods exert pressure on the exterior gasket, creating a tight seal between the door and the outside environment. This innovative mechanism effectively minimizes heat transfer and reduces the impact of external weather conditions on indoor temperature, contributing to energy savings.

Interior Brushes

A set of strategically placed brushes within the mail slot serves a dual purpose. Not only do they assist in smooth mail passage, but they also act as a barrier against drafts, especially in situations where an envelope may get temporarily stuck.

Instalation Gasket and Interior Flap

The installation gasket included with every Uni-T mail slot is designed for easy and secure installation, ensuring a snug fit from the frame to the door that minimizes gaps for enhanced insulation. The instalation gasket not only secures the mail slot in place by preventing slipping but also contributes significantly to maintaining the energy efficiency of the door by preventing unwanted airflow and temperature exchange between the interior and exterior spaces.

The interior flap features a carefully calibrated torsion, providing less torsion to facilitate smooth entry for lighter mail, but enough to keep it closed when opening and closing the door.
