Plastic Washers for Boards Insulation -Celotex Marmox Kingspan 56mm 100pcs

Product Information

Large diameter disc insulation washers, for use with screws to hold insulation materials to battens. When fixing insulation internally, and rust potential is not an issue, carbon-steel fasteners, which cost less, are generally suitable for use. Where fire-safety is an issue, choose from the Insofast range of non-combustible insulation anchors for fastening fire-proof insulation panels, insulated plasterboard and warm roof boards to brick walls, concrete soffits and timber roof rafters.

Insulation frequently forms the part of a buildings external-envelope which maximise its thermal performance; examples include external wall insulation (EWI) and over-rafter warm roofing systems.

The first thing to identify is the type of background material to which the fastener needs to anchor.

These systems need to be held securely to the structure to resist significant wind-loads and stop the insulation from being torn from the building. Twistfix offers a selection of insulation anchors for fastening EWI boards to brick walls, including easy to use plastic insulation fixings and, for where fire-safety is an issue, non-combustible Insofast ISF35 metal fixings to supplement or replace the synthetic anchors. The upside of using metal insulation fasteners is their dependability to continue to function in the event of a fire; the downside is that metal is a good conductor of heat and can provide a thermal bridge through the insulation, resulting in potential heat loss at fastening positions. They can be used as spacers, provide spring force, sealing washers, insulate, lock, align parts, distribute loads, and even improve aesthetics. Experiments on the new substance revealed that it was extremely slippery, which is when PTFE was born.The nature and condition of the building components are likely to have a significant impact on the pull-out resistance of the fixing. Thermal insulating washers are found in nearly every industry, including aerospace, automotive, heating and cooling, plumbing, appliances, the list goes on. Passive fire protection system aims to contain the fire and smoke to prevent them from moving from one part of a building to another. Insulation fixings are one of the essential elements to consider when fitting insulation in a new-build scheme or a retrofit thermal upgrade system. Its texture allows other components and parts to glide over them easily and being thermal but remaining non-conductive, also makes them a popular choice for use in circuit boards.

Twistfix supplies an assortment of high integrity mechanical fixings for securing insulation in new construction or retrofit building upgrades. The weaker and thinner the insulating material, the greater the head-diameter or washer needed to hold it in place and to resist pull-through forces. Some of the most common building insulation sheets are those made from mineral wool, such as those made from strands of glass or rock, foam (PIR, PUR or phenolic), and extruded or expanded polystyrene (XPS or EPS).The pins are generally in the form of nylon or thermally-broken steel nails or screws that drive into the hollow plastic plug. The advantage of using plastic insulation fixings is that they help retain the insulation values of a building by mitigating potential heat loss at fastening positions. Available in a choice of stainless steel or zinc-plated steel these high-performance insulation anchors are quick and easy to fix.
