During the building and renovation process you come across gaps that are just to big to caulk or use a standard gap filler.
BCS has a large expanding foam range for every job. For those large cracks polyurethane expanding foam is the answer. It comes in an aerosol can and sprays on through a nozzle-tube expanding to fill the gap. It cures to a hard foam which can then be cut back, sanded and painted to look real nice..
The Expanding FoamsA one component, self-expanding, ready to use polyurethane foam filler incorporating a CFC-free propellant. After applying from the can, Expanding Foam further expands while curing to a semi-rigid closed cell foam.
Fast, convenient and economical way to fill large, irregular shaped gaps, hollows and cavities in buildings to block draughts, dust, noise, insects and birds.
Includes extension nozzle for easy application. Cured foam can be cut, trimmed, sanded, plastered and painted..
For even more targeted applications there are things like Powers Expanding FoamPowerfoam and TriggerFoam are one-part polyurethane expanding foams that set and cure into their final form by reacting to moisture and humidity present in the air. Their exceptional ability to bond allows Powerfoam and TriggerFoam to be applied to various building elements including the surfaces of concrete, brick, block, wood, steel, aluminium and other miscellaneous metals. Powerfoam and TriggerFoam are safe to use, containing no CFCs. As they are being dispensed, Powerfoam and TriggerFoam have a neutral odour. Cured foam is physiologically harmless.
With Powers Fire FoamFire-FOAM with CFC-free propellant is a single-component, self-expanding, ready to use polyurethane foam with propellants, which are completely harmless to the ozone layer. It has a fire rating of up to 360 minutes in certain configurations.
