If you have a window that is particularly drafty, you can use a space heater to help keep the cold out. Just be sure to keep the space heater away from any flammable materials. A transparent optical quality acrylic panel may be attached inside the existing windowsill utilizing continuous magnetic channels, ensuring a secure and airtight seal around the window after installing a covert Magnetite subframe. The finest insulating kit for windows is simple to install and works well as a draft-sealing barrier. Since windows with insulation treatment often cannot be opened, these kits are a seasonal fix for drafty windows.

Heat flow resulting from air movement e.g. either 'natural' convection - warm air rises, or 'forced' convection - a breeze by a window, both can result in a draught by a window.

How does heat travel through windows?

To apply window film you must first ensure your window is sparkling clean, before measuring it and cutting the film to size. Manufacturer's instructions usually state that you should leave a little allowance in size around the edges. The tape is then applied around the frame ready for the film to adhere to it.

I like bursting bubbles among my fingers, but don’t find bubble wrap the most beautiful way to insulate windows. However, it is a convenient, practical, and cheap solution. If you’re looking for a way to keep your home warm this winter, removable magnetic window insulation is a great option to consider. Window insulation film From top to bottom, press the plastic sheet firmly onto the taped frame. Make sure there are no gaps. A popular option, rope caulk is a putty-like substance that can be applied to the corners of windows easily to minimize drafts. It’s easy to apply and remove, although some are not satisfied with the level of insulation and just like the bubble wrap, it’s not very versatile as you can only use it on windows.

Magnetic Secondary Glazing

In tests conducted for us at the Building Research Establishment, we compared Extraglaze Secondary Glazing against an aluminium system stiffened by sliding framework running down the centre of the window. This stiffness gave it a slight advantage. Whereas the Extraglaze Secondary Glazing had no stiffeners, and looked much better for it. Had we stiffened it we believe they would have been more comparable. Your heater is on, the windows are shut, and yet there’s a draft coming from somewhere. Chances are it’s from those windows. But that doesn’t mean you need to replace them, and it definitely doesn’t mean you have to crank up the heater even more. On the other hand, you might not be able to afford a lengthy and expensive process of insulating every draft-producing corner. So the solution needs to be budget-friendly. If you’re looking for a way to insulate your home for winter, window insulation film is a great option. This type of film is applied to the inside of your windows and helps to create an insulating barrier against the cold.
