SSP / SIA - Insulation fasteners : Choice of system | |
When fixing
insulation boards, sheets, lagging, blocks, mattresses, blankets, quilts, etc..., it is very important that a good mechanical joint is made with the surface to be insulated. Sometimes glue
is used but there is a risk that the insulation media will delaminate and the resulting damage will reduce its effectiveness or cause condensation. Consequently fastening systems which cater for various thickness and give a proper mechanical relationship between the insulated surface and the external face of the insulation are essential. These more desirable systems normally consist of pins which pass through the insulation media and are fixed to the insulated surface by welding, riveting, or by adhesives. Usually the insulation is held in place by a fastening clip or locking washer. This washer is of sufficient diameter to give a strong joint and to provide a bearing surface to spread the load so as not to damage the vapour barrier or retardant. Whichever mechanical system is used it is important that they are positioned for best effect. Around the edges of the insulation where the risk of delamination is more likely there should be more fixings. Other fixings should be distributed uniformly over the rest of the surface to comply with standards or to meet manufacturers recommendations or guidelines. The range of mechanical insulation fastening systems from THOMAS WELDING SYSTEMS offers the standard types to suit whichever application you prefer. Characteristics of each type are as follows. |
