Best Sealent for uPVC Windows

[snaffler]

I am about to have a new smallish kitchen upvc window installed soon by an old mate who is a retired window installer, he has asked me to purchase the expanding foam and a good quality white silicone for the job.

I am looking at the items on sale at Toolstation as my order will be over £10 it makes good sense to buy from them.

The trouble is I am not sure what I am getting or what is the best to get could someone with the knowledge of the products point me to the correct one please.

Expanding Foams
Google "toolstation.com/shop/Adhesives+Sealants/Expanding+Foam/d180/sd2857"

Silicones
Google "toolstation.com/shop/Adhesives+Sealants/Sealants/d180/sd2350"

I am guessing I will need some that adheres to brick and then one that will fix to non porous surfaces.

Any links, products names etc gratefully recieved.

Many thanks

Jason

Use low modular silicone sealant for best effect
