The Domus DDSEAL is a 310ml bottle of rigid duct intumescent sealant, which can seal joints, voids and irregular holes where fire resistance up to 4 hours is required, such as fire walls, partitions, door architraves and floors. This water-based and acoustic rated sealant is designed to swell up and char in the presence of heat, preventing the spread of smoke and fire through the joint.
The sealant has a good adhesion to many common building surfaces, including timber, plasterboard, masonry and concrete. The DDSEAL is suitable for horizontal and vertical joints without compromising the fire rating performance, while it is also over-paintable with solvent and water based paints.

I had an issue with the condition of the aluminium flue I ordered online. It had suffered some damage in transit which was unfortunate. Anita Bowers, the customer service assistant dealt very efficiently with my concern and ensured a replacement was shipped out immediately. This arrived the next day in perfect condition! Great customer service!
