Applications
All standard rendering applications, external wall insulation, timber frame and other weather board systems to provide a drip for rain water at the damp proof course and above windows and doors to prevent return of the water onto the surface below
Chemical
Zero chemical reaction with water, sand and cement, acrylic render, water based paint; avoid organic solvents, chlorate bleach, strong acids and alkalis
Durability
Impact resistant; dissipates shock waves; outlasts metal; cleaned or painted in same way as render
Economics
PVC beads are a fraction of the price of stainless steel; added value over galvanized steel as PVC beads are guaranteed not to stain or corrode. Reduction of impact damage
Environment
Locally manufactured; high recycled content; fully recyclable; low Ecopoint score of 0.004/kg delivered
Fire
Class 1Y. Combustible within fire source, self extinguishing upon removal of flame, will not contribute to the combustion of the system
Health and Safety
PVC beads are safe to handle removing the dangers of cut metal; suitable for prisons and schools
Heat
Ideal for all habitable climates; eliminates cold bridging
Guarantees
Fit for purpose for the lifetime of the render and at least 25 years
Mechanics
115 degree angle prevents return of water onto the substrate below. Will curve through a 4.0m radius
Pollution
Ecologically benign; non-hazardous in water; non-hazardous if ingested; does not release substances into the atmosphere
Strength
PVC beads offer sufficient strength for these applications
Weather
Not affected by weather and should be specified in all regions of high moisture or high salt

Site works
Installation
Standard industry practice and tools can be used. Large irregularities in the substrate should be dubbed out and allowed to set hard prior to application. Cut to length with tin snips or fine tooth saw. Fixing with a continuous line of adhesive mortar is preferred on blockwork, or alternatively a bed of render. Non-corrosive mechanical fixings can be used as well but are not required. With external wall insulation, non-corrosive fixings alone are sufficient.
Storage
Store vertically out of direct sunlight or extreme temperatures. Can be stored flat if supported along entire length
Supply
Ex-stock next day delivery to site through extensive supply chain or direct from www.renderplas.co.uk
