Look the part but can be a nightmare to live with
Pls explain why.
On my travels up and down the country assessing problem jobs or claims for double glazing insurers I often come across astragals and the issues with them are this......
1- Because they're surface mounted you have to clean each square as a separate pane of glass rather than a complete dgu, cleaning your windows will become a days work.
2- Related to the above, window cleaners have to wipe and dry each individual square, squeegees are just to big, this often leads to window cleaners rushing and being too rough causing the bars to eventually fall off
3- Although the bars are held at each end with clips that wrap around the dgu before fitting usually (depending on style) the centre is unsurported and they can start to slip down once the sun has softened the glue on the tape used to stick them on with
4 - Brown woodgrain/rosewood can be a nightmare, these absorb more heat than white and will litteraly bow down, there is no strength or reinforcing in the bars, when the sun gets on them they WILL bow
I remember 1 particular job down in Suffolk, I drove down from the Midlands to inspect a job for the insurer regarding 'issues with geo bars', nice cottage style house and the customer or policy holder as they are to me advised various stick on geo bars have fallen off, upon inspection it turned out to affect every window (about 12 windows) and probably half the bars on each window were loose or had fallen off, she advised that the window cleaner hands them over as and when, while still on site I rang this through, normally I come away and write the report, job was declined for one thing or another can't remember, policy holder trotted out the not fit for purpose line; it all got very messy between them and the insurer, they'd wished they'd never chosen astragalus and wanted the insurer to pay to have all the units changed for internal geo bars, insurer refused as it was roughly a 2k job and then I have an irate ph tearing strips off me and double glazing was all my fault while balling her eyes out.
They look nice but be warned
