One of the best ways to keep warm air in your greenhouse is to ensure insulation is adequate. Sealing any cracks and air leaks is a must! BOSS 399 Silicone Sealer will close these areas, keep drafts off your plants, and maximize any heating elements you have in use.
BOSS 399 Silicone Sealer is a neutral cure sealant and can be used in any weather. The seals dry clear and will be virtually unnoticeable.
