Double sided tape

[Cooper]

Recently I’ve made some secondary “glazing “ frames with softwood and plastic film. I used double sided tape. It seemed to hold very well but though it has stuck well to the film it is failing in the join to the wood.
Does every double sided tape fail to stick to untreated softwood or am I just unfortunate in the brand I bought from our local hardware store? I’m afraid I don’t know the brand as the packaging has been disposed of. The tape may have been quite old as the shop doesn’t enjoy a rapid turnover.
The frames fit massive picture windows in a 1970s timber extension. I hoped they would offer a bit of insulation in a structure that is unsuitable for modern double glazing and would protect some house plants from the worst frosts . I’m loath to do anything more substantial as the whole house is bound to be redeveloped into a block of flats in due course.

Just look for 3M and avoid unbranded or brands with OTT advertising.

Thanks I’ll give that a go.

I think you'd be better using a compressible neoprene double sided self adhesive tape. I had buy a large roll for a repair of a conservatory door. The tape was used to seal the double glazed unit into the wooden frame. This was as per the original design. The tape measures 1 x 10mm. I have about 5m left over which I'll probably never use. You're welcome to try it if you don't mind paying for the postage.
You might get better results if you seal the frame with primer or varnish.

We have some windows, roughly 15 years old, where the tape is failing and some of the little bars have fallen off. I've re-fixed some with (real 3M) tape, and some with outdoor silicone... silicone seems to work just as well. I'm not sure which will last longer. Silicone is always to hand.

Paint the wood first? Tape should stick to that better than wood.

As Yojevol says the neoprene double sided tape is better for that application, timber by its very nature is not flat and needs a bit of leeway when sticking something smooth to it, the 3M VHB Scotch Brand tape would work well for this application.

Reddiseals make good tape in a variety of sizes & thicknesses and I can vouch for the fact it sticks like **** to glazing and bare timber alike. I've never had to use this method although lots advise to apply tape to the rebate and then mist spray with water the glass - since the stuff sticks so well re-positioning is nigh on impossible..
Never had a joint fail and thankfully never had to dis-assemble one - it would take forever and difficult to do without breaking the glass unless it was a robust DG unit..
