Eliminate cold drafts and improve energy efficiency with Barn Fan Covers from Winkler Canvas. Our fan covers are made with industrial 13 oz material that won’t rip or tear. The covers are secured to the fans using a draw belt and light-duty ratchets, creating a tight seal that stops energy loss during the cold winter months. Available in black for fans 12” to 65”.

Beehive Covers, or Beehive Wraps, are an effective method for safe guarding your hives during colder weather. Temperature fluctuations and wind chill can have a detrimental effect on your hives’ population. All of our Beehive Covers are insulated and custom-made to your suit your specific requirements.  We make Beehive Covers for four standard beehive boxes or six nuc boxes. Our Beehive Covers slip over the boxes and notch at the front and back. We also offer an optional dirt flap to seal the hive box off from snow and moisture. Notched entrances are also available when stacking boxes.
