Draught Detection

We are passionate about draught-proofing and draught excluders! Ensuring your home or property is draught free will not only make your home feel warmer but it will also make your home more energy efficient. Draught-proofing is one of the easiest and most cost effective ways of reducing your energy bills. Draught-proofing your chimney can save you 5% on your heating bills, alone. Detecting draughts in your property can be a tricky business and knowing where draughts are coming from can be hard to work out. Draughts can come from all sorts of sources and knowing how to detect draughts is key in making your home more eco-friendly. They can be caused by something as big as an open chimney, which is why we created our Chimney Sheep® draught excluder, or as small as a window frame of floorboard. Draughts coming through small gaps in windows, doors, floorboards and even skirting boards can be hard to detect but just as important to draught-proof as bigger draught sources. This is why we stock the Smoke Pencil!  

The Smoke Pencil is an ingenious gadget for pinpointing air leaks and tracking down hard-to-find gaps. When the trigger is pressed, a plume of smoke-like substance is released. This is actually generated from a harmless glycerine-like fluid, giving off a slightly sweet smell. When the trigger is released, the “smoke” stops, making it highly controllable. The Smoke Pencil Pro Kit comes with attachments that enable a very fine stream of smoke to be created which means the tiniest of air leaks can be pinpointed. 

There are some suggestions that a lit match aid in draught-detection. Whilst that is true it doesn’t last as long and isn’t as safe, particularly in larger or commercial buildings. The Smoke Pencil is safe to walk around a room or property with, without causing any fire hazards.
