What is the difference between caulk and adhesive caulk?
What makes adhesive caulk different from other types of caulk is its adhesive property. Most caulks have a fixed lifetime, after which they have to be re-applied or “recaulked.” Adhesive caulk, however, typically has a longer life than many other caulks because of the additional adhesive properties in the caulk.
What is the difference between adhesive caulk and sealant?
The main difference between a caulk and a sealant is elasticity. Caulks are fairly rigid when dry, and are intended for use in areas with minimal expansion and contraction. Sealants are made from flexible material--most commonly silicone--making them ideal for areas prone to expansion and contraction.

Is glazing putty better than silicone?
When it comes to things like old windows traditional glazing putty is a much better choice. It has a similar lifespan of 20-30 years and at the end of that time it can be removed without damaging the wood.

That brings up another point about silicone.
