ACCOYA CLADDING ON A TIMBER FRAME

Transcription

1 SUB-FRAME Accoya is the worl s leaing high technology woo. It is prouce from sustainably source, fast growing softwoo using a non-toxic moification process, resulting in a urable, stable an beautiful material with excellent performance characteristics an proviing for a minimum 0 year above groun life. Like all claing materials, Accoya claing performs best when installe properly on a suitable frame an in a ventilate façae system - characterise by continuous ventilation behin the claing boars, through ventilation in- an outlets situate at the top an bottom of the façae. This ensures rain water an conensation behin the claing to be remove an for the insulation to retain its effectiveness. The sub-frame the claing is fastene to shoul have a maximum spacing of 00 mm on center an shoul consist of timber battens of at least x mm when fully supporte by a substrate. Horizontal battens an counter battens shoul be at least 0 x mm. Support battens use with Accoya soul be of a urability class or. In case of a iscouloration risk of the claing boars because of leaching of extractives from the timber subframe, apply a barrier between the sub-frame battens an the boars. Timber support battens shoul not be use above m builing height. In case of claing, best practice is a ouble sub-frame where horizontal support battens are fastene on counter battens. The horizontal battens shoul be chamfere at the top sie, sheing water into the cavity. The lowest batten shoul slant inwar at the bottom, creating a rip lip at the intersection with the counter battens. If only horizontal support battens are use, aitional measures nee to be taken to ensure sufficient ventilation (00 mm per m horizontal length), e.g. by making cut-outs in the battens or interrupting the battens at regular intervals, staggere relative to each other. In this case it is preferable if the horizontal battens are chamfere on the top ege to she any water outwars. Water penetration at the en grain of battens shoul be avoie by applying a suitable sealer. CAVITY ACCOYA CLADDING ON A TIMBER FRAME Accoya is suitable for stanar claing types, an in general the installer shoul follow the same recommenations for fitting as with traitional woo claing, requiring no special etailing or tools, an performs best when installe properly on a suitable frame. Accoya woo can be cut, profile an routere to specifie esigns without encountering restrictions or issues associate with the instability of traitional woo claing while maintaining its urability. FASTENERS Accoya can be face fixe onto the timber sub-frame with ring shank (or other improve) nails or screws (raise or roun hea). As Accoya is slightly aciic, like most urable woos, it is recommene to use stainless steel grae.0 (general applications) or grae.0 (for coastal or inustrial sites). Stapling is not recommene, nor to rive the nail or screw heas into the woo. T-nails shoul not be use for external claing as they offer little resistance to axial withrawal. Lost hea nails shoul also be avoie as they offer little resistance to pull-through. To ensure a urable an lasting fixation, the boars shoul be fixe with at least 0 mm clearance to the en of the boar (pre-rill holes to mm less than the screw shank iameter or 0% of the nail iameter). The minimum istance to the top an bottom ege of the boars is mm. The recommene point sie penetration of nails into the sub-frame is at least x for ring shank or x for smooth nails. If the nail hea is larger than twice the shank iameter, assumely pull-through will not occur, as the pull-through resistance excees the withrawal resistance. Point sie penetration x (ring shank) / x (smooth) x mm COATINGS mm UK Coatings are applie to Accoya for largely aesthetic reasons. Please refer to the general guiance given in the brochures provie through accoya.com an the applicable avice from coating manufacturers.

2 Accoya claing James Latham profiles vert + hor : / HWI Because of the improve stability of the Accoya woo, the gap neee between the height of the boars is very limite, an can be as little as mm. This permits spacing to be built into the profile rather than use of a spacer on site. The spee of installing Accoya claing boars can be increase significantly by the crusher bea mille into the James Latham tongue an groove profile. This bea will insure the necessary spacing when installing the boars without aitional measures. If an when the boars move relative to each other, this small triangle of material will be easily presse together, releasing the necessary istance. When meeting other construction elements an/or between the length of two boars, a free space of - 0 mm shoul be allowe for. When this free space is left open, a vermin mesh might be require at certain joint withs. Please check local builing coes to verify requirements. mm mm mm / mm mm / mm James Latham LT AC 0 tongue an groove profile for claing mm mm James Latham LT AC 0 tongue an groove profile for horizontal claing
