About this window & upvc seals
Single-glazed sashes, old casements and draughty frames in rented homes often cannot be fitted with permanent seals. A clear tape is the seasonal answer: you stick it over the gaps in autumn and peel it off in spring, leaving the original window untouched.
This XFasten roll is 50.8mm wide, which is wide enough to bridge the gaps around a sash edge or cover a crack between the frame and the wall, and it is 27.43m long. That is a lot of tape for the price, and it comes in a clear finish that is nearly invisible against glass and timber.
The manufacturer describes it as wood-safe and residue-free, with a pressure-sensitive adhesive that is airtight and watertight. As always with tape, test a small hidden area first on a delicate or freshly painted surface, and remove it slowly at a low angle when the weather warms up.

Got questions?
27.43m (30 yards), and 50.8mm (2 inches) wide.
It is designed to remove without residue, but test a hidden spot first on fresh or delicate paint.
It is clear, so it is close to invisible, though a visible edge may show up close.
It is designed as a seasonal or temporary seal rather than a permanent fix.
Look at your existing seal or the gap around the sash, then compare the groove width and profile shape with the details on this page, because a seal that is the wrong profile will not close the gap properly.
Delivery within the UK is free on orders of £30 or more and a flat £3.99 below that. The delivery estimate for your address is shown at checkout before you pay.
The complete guide
Many tenancies forbid screwing or drilling into window frames. A clear tape that removes cleanly is the sensible compromise.
The gaps between sash and frame, and any cracks between the frame and the wall.
Peel the tape off slowly in warm weather, with a hairdryer on low if it resists, and clean any glue off with a little white spirit on a cloth.
