Fixings for secondary glazing

[tabbypurr]

For light acrylic secondary glazing what methods of fixing could you recommend?

I'd suggest double sided sticky foam tape, or aluminium or PVC angle, or wood quadrant, or foam tape combined with one of the latter. I can't recommend, as I've not got around to doing the job yet (and now that it's warmer I probably won't for another year).

Do you mind what it looks like?

Needs to be fairly airtight or you will have problems. The self adhesive magnetic strip and metal strip works OK but it is hard to apply neatly in longer lengths. Silicone foam strip to seal and small clamps (which could be mutilated white cable clips if you don't care about looks).

Angle or quadrant mouldings wouldn't do the job, they don't fit the frame s hape. The glazing will sit on the face rather than within the frame. I'm no t against the latter but it's hard to see how that would work prperly. Doub le sided sticky tape sounds a right mess and a recipe for broken glazing wh en removed.

Naturally what it looks like matters. It needs to be not too hard for the a verage Joe to remove, cut cable clips are out. Clamps of some sort are what I had planned, the question is, if I go that route, what sort of clamps. T he original window frame is shallow, shaped like so:

I use this for glass secondary glazing. The plastic edging gives a fairly neat appearance:

You can get it for various thicknesses.

That looks a lot more like it. Their packs seem a little expensive, £2

4 or so for a 15m length, and I wish they had decent looking clips, but tha t would get the job done. Thank you.

There are standard clamps, a sort of a boss which the screw goes through with a tag that you can rotate for fitting or removing the framed glazing easily. Incidentally, polycarbonate sheeting is much cheaper than acrylic. It does eventually become cloudy from UV even inside, but it lasts quite a long time IME.
