Thermacell – Insulating cellular blinds

Thermacell blinds are designed to fit tightly into your window jamb. This enhances both the insulating and room darkening properties of the blind.

Insulation is achieved by trapping a still layer of air in the honeycomb construction of the fabric, thereby creating an effective barrier between the exterior and interior of your home. This still air layer reduces heat transfer and saves you money on your power bill both in summer and winter.
