ACCESSORIES

Fixings
Envirowall supply a comprehensive range of anchors to suit a broad range of applications. From the standard insulation anchors to more technical applications we are confident that we can offer a cost effective and technically sound solution to your requirements. All of our fixings are quality controlled throughout the design, material selection and production process to ensure compliance with the safety requirements of the individual applications. On site pull out tests may be provided so the correct fixing, and fixing pattern are always specified for each project. As with all our products, Envirowall make a commitment not to over specify our fixings to ensure our systems offer the most economic solution to your needs.

TID-T 8/60*75-295mm For fixing insulation up to 260mm thick into concrete and brickwork. Polypropylene expansion anchors supplied with zinc plated carbon steel pin for extra pull out strength and fire resistance. Different lengths are colour coded for easy on site identification, supplied pre assembled for ease of use and rapid installation. This product should be specified where the compressive strength of the substrate is low.

TKR-4.8*35-300mm
TKE-4.8*50-100mm Stainless Steel option For fixing insulation into 0.7-1.2mm steel or timber and cladding boards. The TKR is a drill tipped carbon steel screw with an organic corrosion resistant finish. The TKE is an identical fixing but made from A4 grade austenitic stainless steel with a carbon steel drill point. Both are used with a variety of washers to fix insulation, or without when fixing various cement particle boards, such as superflex and betapan or to timber and steel frames.

VHT-R-4.8*50-150mm For Fixing Insulation into 0.7 to 0.9mm steel or timber deck. The VHT-R fixing is a needle point carbon steel screw with a an organic corrosive resistant finish. Used in conjunction with various washers for fixing insulation to cladding boards, such as superflex or betapan as well as timber panels such as plywood.

Reinforcement Mesh
Supplied in 50m2 rolls (50m long by 1m wide) Envirowall glass fibre reinforcement mesh is used to add extra strength and impact resistance to basecoats, both in a render only context and when applied as part of an external wall insulation system. The reinforcement mesh should be applied as near to the outer surface of the basecoat as possible to provide the most effective protection.
It is not always necessary to use a reinforcement mesh in render only applications, depending on different specifications. Please consult the technical department with any queries.

Armour mesh is a heavy duty version of reinforcement mesh which provides a more robust reinforcement to render only and EWI applications. Armour mesh should be specified in areas where a high impact resistance is required generally at ground floor level, in buildings with high levels of activity such as schools and prisons.

Beads Trims Flashing's Profiles Envirowall source a comprehensive range of beads, profiles, trims and flashing's from a variety of suppliers and all are available in a variety of materials to suit all the requirements of our insulation and render only systems.

PVC Primarily used in the manufacture of surface mounted beads PVC is durable and weather resistant. Available in a variety of colour's PVC beads are light weight and cost effective as well as being easy to install. Both rigid PVC (DIN 7748/1) and non-rigid PVC (to an appropriate shore-hardiness) are used according to the requirements of the specific application.

Galvanized Steel Galvanized steel is used throughout the range of surface and full system beads on the traditional thick coat systems. Beads and trims are generally supplied powder coated white, although coloured powder coating can be arranged, and with the choices of having a PVC nose, again in a range of colour's, to protect the visible element of the bead. All Galvanized products are manufactured to BS EN10143:1993 and BS 5262:1991 (code of practice for External Renderings). A Full range of fabricated flashing's and window sills are also available measured and manufactured to site specifications.

Stainless Steel Stainless steel alternatives are available for all galvanized products depending on the specifier needs and the local environment of the site. All stainless steel products are manufactured to BS 1449/2:1983 and EN 10088/2:1995 (Stainless Steel 304 Grade).

Aluminium Full system stop beads and base beads for insulation systems using thin coat renders are generally manufactured from aluminium. The light weight nature of thin coat render systems, in comparison to traditional thick coat systems, means the trims have different requirements in strength, weight and the level of detail required in manufacturing. All aluminium products are manufactured to EN 485/4:1994. Common Surface Beads.

Angle Beads Surface mounted angle beads provide a clean straight edge and additional strength at external angles. Available in a range of sizes and colour's, used mainly with traditional thick coat applications on both insulated render and render only systems.

Mesh Winged Angle Beads Surface mounted PVC angle beads incorporating wings made from reinforcement mesh. Buried within the render system at the surface of the base coat this bead is used to provide additional strength and a straight edge at external angles on thin coat applications.

Mesh Winged Stop Beads Termination bead incorporating a reinforcement mesh wing, generally used in thin coat applications. Apu beads available with removable window protection and sealing strip providing a water tight shadow gap.

Expansion Beads Mainly required with traditional thick coat render systems surface mounted expansion beads are used to protect the render from cracking due to thermal or structural movement in the substrate. Expansion beads must be specified where there is a structural movement joint under the render and also where there is a change to the background substrate.

Overhead Drip Bead Used at window heads or similar overhangs to prevent surface rain water traveling under the return.

Full System Beads

Full System Beads Full system base beads are used at or above the DPC level to form a horizontal starting point for the insulated render systems. Slightly different in design for thin coat and thick coat systems both types incorporate a drip to shed surface rain water away from the substrate. Available in a wide range of sizes to accommodate varying thicknesses of insulation, the thick coat base bead is available with a coloured PVC nose while the thin coat base beads incorporates a locking plate along the front edge for additional strength.

Verge Trims, Fabricated Flashing's and Sills A standard range of verge trims and window sills are available from stock to suit most insulated render systems. Custom fabrications including oversills, copings, feature channels and louvred access panels are also available made to site requirements. A full range of accessories also complement these products including welded corners and jointing pieces.

Cladding Boards Envirowall offers two types of cladding boards for use on both timber and metsec frames.

Superflex is a high specification cladding board which can be rendered directly onto with a flexible basecoat and thin coat render finish. Supplied in 2400mm*1200mm sheets Superflex is an autoclaved cellulose fibre cement board, completely asbestos free it is tough, durable and dimensionally stable. Both 9mm and 12mm thicknesses are available.

Betopan is a lower specification cladding board which is suitable as a carrier for an insulated render system but not for direct application of render. Again very durable and resistant to moisture betopan is a cement based board offering a more economical alternative to superflex but with a small linear expansion which makes it unsuitable for the direct application of renders.

Sealing Tapes Pre compressed expanding sealing tapes are typically used to ensure the water tightness of joints between the insulation system and frames, or any other areas susceptible to water ingress. Supplied in 10m rolls, when used under high compression ratio these tapes offer excellent weather sealing over long periods of time.
