## Description

Effortlessly seal and draught-proof your sash windows with the Gapseal Sash Window Seal. This 10m strip is specifically designed for windows, expanding to fill gaps up to 7mm wide. Its water-resistant, siliconized acrylic material ensures durability and a smooth, paintable finish. Ideal for caulking, it hardens in just 30 minutes, providing an effective barrier against cold air and water ingress. Available in magnolia color, it's a versatile solution for your window sealing needs.

Review: Drafts from sash windows gone - I read somewhere that if you add together the area of all the gaps around a sash window, you have the equivalent of a small pipe blowing cold air directly into your room from outside. Gap seal has worked perfectly to close all the gaps around the window, and the room feels instantly warmer. This is going to save a fortune throughout the colder months. I've previously used the temporary plastic sheeting, but that leaves a persistent residue that is difficult to remove. I've also repainted all my windows so didn't want to ruin the finish with yellowed adhesive. So if you're contemplating the plastic film, try the gap seal instead. I understand what some reviewers are saying about it being difficult to fill smaller gaps, but I got around this by stretching the product as its being applied, making it easy to wedge into the smaller gaps with the included tool. There's a bit of a knack to it. You want to leave at least some small gaps to retain some form of ventilation. Edited: for some of the really small gaps, I just cut the seal down the middle and it fit easily
Review: Good product - Good product, does the job but you can’t open the windows after. Takes time to fit and ok to re fit if you take it out and place it later. It got me through the winter months of cold draft victorian windows.

### ⭐⭐⭐⭐⭐ Drafts from sash windows gone
*by T***S on 27 September 2022*

### ⭐⭐⭐⭐ Good product
*by F***N on 13 April 2024*

Good product, does the job but you can’t open the windows after. Takes time to fit and ok to re fit if you take it out and place it later. It got me through the winter months of cold draft victorian windows.

### ⭐⭐⭐ Suitable for larger gaps only
*by C***S on 4 November 2024*

Soft silicone can be pushed into larger gaps ok and seals well. But difficult if gap less than 4mm as doesn't compress very easily and the tool provided just cuts into the foam. A blunt flat head sscrewdriver is slightly more effective but also starts to stab into the foam as gaps get smaller. Removable with no mess as no adhesive. But that does mean the product is not suitable for windows you wish to open and close.
