Easy to use. Filled holes around window frame. Wanted the low expansion foam not to to exert to much pressure on the frame. The controller easy to use and easy to clean up the nozzle and reuse again.

Good product.. waterproofer and insulator

Really like the multiple use nozzle design. I used the can several times over three days and it worked fine.

Adequate coverage and can be kept for a bit

It doesn't go as far as I'd expected but it does a good job of filling gaps. In theory the nozzle can be sealed by screwing part of the cap on the end of it, and that works. But just wait until you try to unscrew the thing again and the dried foam has locked it on. I ended up pulling the whole nozzle out of the tube for my second application!

Perfect for the job

Needed the window and door foam for a front door installation, I’ve used it previously and it’s just as good as ever, the 2 hour cure time is good and the control you have when using it is great. I’ll be buying more as I have a couple of windows to install soon

Great product, used to fill gap around door frame. Beware it expands more than you think it will, so easy on the trigger

Easy to use. Dispersal works well. Probably a bit expensive though.

Quality stuff... one to keep in mind if you want a frame fixing foam.

I liked this foam! Wanted something that did not expand too much as using it for frame fixings and worked a treat. Good nozzle control meaning it did not go everywhere and also it did not clog up after a few hrs as was able to use again the next day.

Great product easy to clean off plastics.

Does what it says on the tin. I've found this stuff is much easier to clean off plastics and glass.

Never had this product before, bought it from Northallerton, got it home and only then did I realise that the top flap of the cap had been snapped off before it was given to me, which annoyingly also had the airtight twist on bung attached to it so I couldn’t use it again after he first small job. REALLY annoyed.

Low Yield

Surprisingly low yield from one can compared to other Soudal products I've used. Also hard to control as it comes out very fast as others have mentioned.

This is exactly what you need when putting in windows and doors. This is not the first time I’ve purchased soudal products and they definitely work.

Bought for filling in around some windows we fitted ages ago but never got round to finishing off. Good filling, firm foam when cured and didn't try and push the window or plasterboard surround apart too much. Hopeully will be enough and still active to do another couple of windows when I get the time.

Good value sticky foam

I mean it’s foam, it foams good and sticks your clothes and gloves together really well.
