A variety of factors will determine the most suitable type of fasteners to choose when fixing insulation, and Twistfix offers many options to satisfy project requirements. There are many instances where non-combustible fixings are preferable or mandatory for use when fitting insulation to a building. PTFE is a polytetrafluoroethylene (PTFE)-based synthetic fluoropolymer of tetrafluoroethylene, a high-molecular-weight compound consisting of carbon and fluorine — and is one of the most commonly used artificial substances in the world. 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.
Failure of an external insulation system can occur if pull-out loads wrench the fixing system from the building or pull-through loads cause the insulation to fail and pull over the heads of the fastener. It is common for pragmatic designers to specify an insulation fastening system that combines the attributes of both plastic fixings and steel anchors. Passive fire protection system aims to contain the fire and smoke to prevent them from moving from one part of a building to another. The disadvantage of using plastics and nylons is that they are combustible and are incompatible with an insulating system where fire-resistance is a constraint.The next consideration is the size of the fasteners head; this is the part of the anchor that clamps the insulation to the structure. They can be used as spacers, provide spring force, sealing washers, insulate, lock, align parts, distribute loads, and even improve aesthetics. When insulation needs fitting externally, consider the use of stainless steel, which offers excellent resistance to corrosion. It is perfect for fixing plywood or OSB faced insulation sheets to rafters in warm flat roof applications.
In external wall insulation systems for low-rise buildings, the designer may prescribe the use of the more thermally efficient plastic fasteners, supplemented by using fire-safe mechanical fixing per board. 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. Insulation fixings are one of the essential elements to consider when fitting insulation in a new-build scheme or a retrofit thermal upgrade system.We manufacture the PTFE washers to an ISO 9001 standard, so each job we do has a full material traceability and a full dimension report once the goods go through final inspection. As leading PTFE washers UK suppliers, Stephens Gaskets is proud of our top quality, wide-range of thermal insulating washers . To limit heat loss caused by thermal-bridging, contemplate using metal fixings having a small cross-sectional area and those that have the least area of contact with the background material.
The first thing to identify is the type of background material to which the fastener needs to anchor. The nature and condition of the building components are likely to have a significant impact on the pull-out resistance of the fixing.
PTFE washers are strong, durable, and have one of the lowest coefficient friction levels of any other solid material. When hammered in, the stainless-steel 7mm helical fasters corkscrew into the timbers when hammered in to firmly hold the insulation in place. com/p/SPAX-1-3-4-in-Dia-Plasti-Grip-ci-Prong-Insulation-Washers-75-Count-5019677517509/308052360" on this server. The pins are generally in the form of nylon or thermally-broken steel nails or screws that drive into the hollow plastic plug. Plastics fasteners tend to be slow to ignite but once ignited they can melt and lose their ability to hold the insulation in place.
