Locally manufactured from recycled plastic, Renderplas PVCu movement joint beads / expansion joints are designed for areas of render over 20 square metres and should be specified every 4-6 metres, over structural movement joints and changes of background. Discreet but strong, all beading gives a perfect finish to through colour render and is equally suitable for sand and cement

Applications

Horizontally or vertically on all standard rendering applications, external wall insulation systems, timber frame; as a day joint to divide rendered sections; at changes to background material

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 in same way as render

Economics

PVCu beads are a fraction of the price of stainless steel; added value over galvanized steel as PVCu beads are guaranteed not to stain or corrode and can reduce installation time. 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

PVCu beads are safe to handle removing the dangers of cut metal; suitable for prisons and schools

Heat

Ideal for all habitable climates

Guarantees

Fit for purpose for the lifetime of the render and at least 25 years

Mechanics

Flexible plastic membrane gives a certified range of +/- 2.5mm which exceeds British Standard for thermal movement (BS EN 13658-2:2005). Protective tear off strip allows quick removal of render from the joint

Pollution

Ecologically benign; non-hazardous in water; non-hazardous if ingested; does not release substances into the atmosphere

Strength

PVCu beads offer sufficient strength for these applications. The chemical bond between flexible and rigid parts prevents separation

Weather

Flexible plastic membrane provides a watertight seal. 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
