Advice on new windows

[Devlin]

Hello everyone

 

I am currently looking into replacing the 15+ year old windows in my house. I live in a typical Victorian house. Not exactly the most efficient building out there. Anyway, I want to do this right.

 

My concern is that I go to a local installer, they come round fit the window, shove some bog standard expanding foam round edges and finish it off with a bog standard sealant round the edges. We all high five each other and I’m left a few grand poorer and with a potentially sub-standard installation.
 

I want to invest in good quality windows and I don’t want them to be let down by poor finishes. So, what is the best way to deal with finishing off around edge of the window/frame? I’ve read about airtight sealants and tapes added on top of a suitable high quality foam that fills the gap. Are these recommended/necessary? Do I need both sealant and tape?

 

Also, what is the best way to ensure insulation around the internal reveals? 
 

Thanks for any help and guidance.

The Illbruck products are well thought of:

For a replacement, all you need is a good quality PU foam, mastic externally and maybe some new trims.
