What: Cornice is a type of moulding which runs along top lengths of your interior walls, which sits in the joint between the walls and the ceiling. Cornices are generally made of polystyrene, it is lightweight, durable, easy to handle and suitable for all dwellings.
Our cornice range includes Extruded (XPS) as well as Expanded (EPS) cornices.
XPS (Extruded polystyrene) and EPS (Expanded polystyrene) refers to the type of polystyrene that we use to manufacture our cornices from.
XPS has a smooth finish, whereas EPS has a slightly rougher appearance and is significantly cheaper. After painting, the EPS is suitable for most clients/homeowners. Both are high density products, which is important to note. XPS is high quality, high density cornice that requires minimal paint. EPS is coarser and has a lower density. These cornices are environmental friendly polystyrene cornices made from recycled material which come in a range of different profiles.
Manufacturing process
Expanded polystyrene is lightweight and made from solid beads of polystyrene; expansion is achieved by virtue of small amounts of pentane gas dissolved into the polystyrene base material during production. The gas expands under the action of heat, applied as steam. These cells divert roughly 40 times the volume of the original polystyrene beads. The expanded polystyrene beads are then moulded into approximate forms suited to their application.
Extruded polystyrene is made on extruding machines in the form of continuous foam billets, polystyrene is melted and after addition of any foaming addition it is then extruded through a nozzle with a broad slit on a foam billet then ran through a cooling zone of sort and cut to suited size.
Highly durable and lightweight
1. Ensure all surfaces are clean, free of dust and grease.
2. Cornices should be cut using a fine tooth panel saw or hacksaw. Please cut corners using a mitre-box for best results
3. Expect to use approximately 50ml adhesive per meter for smaller profiles, and 100ml per meter for larger profiles. Double the amount of adhesive anticipated if the wall surfaces are uneven.
4. Apply a liberal bead of adhesive to top and bottom of cornice. Press firmly to hold in position.
5. Wipe away excess adhesive with a damp cloth or sponge.
6. Large profiles may require additional support on either the vertical or horizontal surface for positive fixing.
7. Leave a 2mm space between adjacent cornices on long runs. Fill with adhesive.
8. Repair dents, chips and marks with adhesive diluted with water to paint consistency. Apply with brush.
9. Paint profiles with water based paints or stains.
10. Profiles are water resistant and can readily be installed in bathroom and kitchens
11. Cornices can readily be expected to last for the duration of the building
12. Large profiles can be used to cover existing installed cornices.
