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

Product Information

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 use of such synthetic fasteners helps to fulfil the objective of retaining the utmost insulation values of a building by mitigating potential heat loss at fastening positions. As leading PTFE washers UK suppliers, Stephens Gaskets is proud of our top quality, wide-range of thermal insulating washers .

Particular types of fire-resistant composite insulation boards can safeguard a building from fire hazard by providing passive fire protection. com/p/SPAX-1-3-4-in-Dia-Plasti-Grip-ci-Prong-Insulation-Washers-75-Count-5019677517509/308052360" on this server.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. Thermal insulating washers are found in nearly every industry, including aerospace, automotive, heating and cooling, plumbing, appliances, the list goes on. 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. 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.

Also consider that stainless-steel conducts just 25% of the heat conducted by zinc-plated carbon steel, making the former up to four times as thermally efficient.

Melting fasteners present many hazards including the release of smoke and toxic gasses, flaming droplets which spread the fire, and fallen insulation boards that block escape routes.

Large diameter disc insulation washers, for use with screws to hold insulation materials to battens. 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 majority of insulation-fastening plugs are of plastic or nylon composition and are poor conductors of heat. It is common for pragmatic designers to specify an insulation fastening system that combines the attributes of both plastic fixings and steel anchors.

There are many instances where non-combustible fixings are preferable or mandatory for use when fitting insulation to a building. 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. Insulating materials are made from a diverse selection of materials and are available in a variety of thicknesses. Insofast ISF35 fixings are a superb option for fixing slabs of insulation beneath concrete soffits and car park ceilings.When fixing insulation internally, and rust potential is not an issue, carbon-steel fasteners, which cost less, are generally suitable for use. PLEASE NOTE:Once installed, the head of the fixing should be taped and sealed to avoid any contact with wet plaster. Class A1 fasteners will not contribute to a fire at in any stage nor will they present a smoke hazard. The next consideration is the size of the fasteners head; this is the part of the anchor that clamps the insulation to the structure.

Several fastening systems are set up such that upon installation, the head sits in a shallow recess, slightly beneath the surface of the insulating material. 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. Experiments on the new substance revealed that it was extremely slippery, which is when PTFE was born.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. Fixing solid composite insulation boards to the structure of a building requires fasteners more traditional sized heads.
