tremco illbruck: i3 System - Window Installation

[@kathryncushing1856]

Can you suggest any variations required if the window is sited on the internal wall edge, not the external. Can I still use this system? What would you suggest?

[@guodomitsu9415]

do you really need a foam when using pre-compressed tape?

[@robhalliwell3155]

The PU Foam is a special elastic Formular that provides thermal and acoustic insulation- features that are often overlooked when high performamce windows are installed. U-values should be matained but unfortuntaly the gap between window and wall lowers efficiency. FM330 is one way of maintaining performance. It remains flexible and can accommodate movement between elements without being disturbed or degraded. This is not a normal foam. The whole illbruck i3 system is based on advanced building physics and include a whole range of adapatebale and integrated measures. What you saw in the video is just one "standard" approach. Windows that are A rated deserve an A rated installation otherwise the investment is pointless.

Got any questions regarding illbruck solutions? May be I can help.

why the massive gaps round the new window?

[@robhalliwell3155]

Agreed gaps tend to be much larger than one would hope. For some unknown reason we seem to be incacapable of buildig to and mainatining tight tolerances in the UK. Therefore designed toerance gaps of 10mm quite often end up being any where between 10-20mm. Its poor workmaship and possibly lack of site management. The other reason particularly with modern composite windows is that they are increadibly heavy-which means that more "wiggle room" is needed to manhandle the frame in to position. Its not ideal but we seem to be "living with it".

This is exactly how I would do it, awesome job!

Lot of fannying about just to fix 1 window,! 😠😠😠😠

[@craigf136]

It's extra work granted but that's the problem in the UK in general, do it quick, not what's best.

[@robhalliwell3155]

The same result can be achieved with a single illbruck product in a cavity wall opening. Agreed a three step proceedure is probably more time consuning but there are other options avaiable. Search for illbruck TP652, TP653 or TP650 muiltifuntion sealing tapes. The later is ideally suited to domestic replacemnt windows and is a low cost option providing very high airtightnes and weather prtection that will last as long as the life of the window and with no mainatainence. There is more than one way to skin this cat if one considers themsleves to be a preffessional window installer.
