Exclusive to Firmseal, our Slim-Jim uPVC window offers less frame and more light.
Great for when you have small windows in your home and less visible frame thickness is important such as stone mullion windows, metal casement windows, heritage windows.
These windows are especially popular in Bath and the surrounding area due to a large majority of the properties having a lot of the above types of windows.
Less frame obviously means more glass which means you gain more light, which is also a welcome added bonus.
We often have customers that visit us looking for aluminium windows in their home who instead end up choosing our “Slim Jim” over aluminium as they are just as slim and can also be supplied in a host of colours, especially in a beautiful range of greys which look very much like aluminium but at a more attractive price.
But please be aware “Slim Jim” is only available from Firmseal: ask for it by name!
