Subscribe Pipe Insulation Pipe insulation materials are used to retard the flow of heat energy by reducing heat loss or gain from pipe work and also as acoustic insulation. Adding pipe insulation will keep the heat in your heating system. It will reduce the amount of energy you use to heat your water and hot water will stay hotter for longer. Wrap the insulation round your pipes and you will notice the difference straight away.

Subscribe Pipe Insulation Pipe insulation materials are used to retard the flow of heat energy by reducing heat loss or gain from pipe work and also as acoustic insulation. Adding pipe insulation will keep the heat in your heating system. It will reduce the amount of energy you use to heat your water and hot water will stay hotter for longer.
Wrap the insulation round your pipes and you will notice the difference straight away. Moisture is known to contribute towards many different types of corrosion, so preventing the formation of condensation on pipework is important. Pipe insulation can prevent condensation forming, as the surface temperature of the insulation will vary from the surface temperature of the pipe. Some water pipes are located either outside or in unheated areas where the ambient temperature may occasionally drop below the freezing point of water, any water in the pipework may potentially freeze.
When water freezes, it expands due to negative thermal expansion, and this expansion can cause failure of a pipe system. As pipework can operate at temperatures far removed from the ambient temperature, heat flow from pipework can be considerable. In many situations, this heat flow is undesirable. The application of thermal pipe insulation introduces thermal resistance and reduces the heat flow.
Where pipework is operating at extremely high or low temperatures, the potential exists for injury to occur should any person come into physical contact with the pipe surface. As the surface temperature of insulation varies from the temperature of the pipe surface, pipe insulation can be used to bring surface touch temperatures into a safe range. Pipework can operate as a conduit for noise to travel from one part of a building to another.
Acoustic insulation can prevent this noise transfer by acting to damp the pipe wall and performing an acoustic decoupling function wherever the pipe passes through a fixed wall or floor and wherever the pipe is mechanically fixed. Rock and Slag: Rock and slag fibres are bonded together with a heat resistant binder to produce mineral fibre or wool. Upper temperature limit can reach C.
Cellular Available in board and block form capable of being fabricated into pipe covering and various shapes. Service temperature range is C to C and to C in composite systems. Good structural strength, poor impact resistance. Material is non-combustible, non-absorptive and resistant to many chemicals. Calcium Silicate Calcium Silicate is a granular insulation made of lime and silica, reinforced with organic and inorganic fibres and moulded into rigid forms.
Service temperature range covered is 35C to C. Flexural and compressive strength is good. Calcium silicate is water absorbent. However, it can be dried out without deterioration. The material is non-combustible and used primarily on hot piping and surfaces. Finishing material is applied on site. Expanded Silica or Perlite Perlite is made from an inert siliceous volcanic rock combined with water.
The rock is expanded by heating to above C causing the water to vaporize and the rock volume to expand. This creates a cellular structure of minute air cells surrounded by vitrified product. Added binders resist moisture penetration and inorganic fibres reinforce the structure.
The material has low shrinkage and high resistance to substrate corrosion. Perlite is non-combustible and operates in the intermediate and high temperature ranges.
The product is available in rigid pre-formed shapes and blocks. Elastomeric Foam Foamed resins combined with elastomers produce a flexible cellular material. Available in pre-formed shapes and sheets, elastomeric insulations possess good cutting characteristics and low water and vapour permeability.
The upper temperature limit is at C. Elastomeric insulation is cost efficient for low temperature applications with no cladding necessary. Resiliency is high. Consideration should be made for fire retardancy of the material. Foamed Plastic Insulations produced from foaming plastic resins create predominately closed cellular rigid materials. Lambda values decline after initial use as the gas trapped within the cellular structure is eventually replaced by air. Foamed plastics are light weight with excellent cutting characteristics.
Foamed plastics are generally used in the lower intermediate temperature range. Refractory Fibre Refractory fibre insulations are mineral or ceramic fibres, including alumina and silica, bonded with extremely high temperature inorganic binders, the mechanical interlocking of fibres eliminates the need for any binder.
The material is manufactured in blanket or rigid form. Thermal shock resistance is high. Temperature limits reach C. The material is non-combustible. Phenolic Foam Rigid closed cell foamed insulation manufactured from phenolic resin. Application of Insulation Material to Pipe Work Insulation products should only be applied to pipe work which is clean, dry and unheated.
Do not compress pipe insulation sections at joists, studs, columns, ducts etc. This is important because any insulation loses some of its insulation value if it is compressed. On cold pipes condensation may occur where the insulation is compressed. Space should be allowed around pipe work to help air circulation. Air movement is an extra safeguard against condensation on cold pipes especially in hot, humid weather.
Never stretch the pipe insulation sections. Always use the proper size of insulation for the job. Do not stretch it over the pipe. Butt-end joints can be made without stretching the lengths of insulation. Proper sealing of all pipe insulation is important to minimise heat loss and control condensation. On cold lines, open pipe insulation joints may allow the formation of condensate drip or contribute to possible pipe or tubing corrosion.
All insulation joints should be sealed as shown in the insulation instructions. Here at Insulation Shop you can find a various types and sizes of pipe insulation sections from leading manufacturers, such as Rockwool and Kingspan.

Metal Building Insulation Metal Building Insulation The Simple Saver System is a high performance insulation and finishing system designed for roof and walls in low rise commercial buildings. The Simple Saver System is a high R-value insulation system for metal buildings that also provides through fall protection when properly installed. Simple Saver System will yield designed insulation values without excessive compression and voids, which are common with other methods of installation. The Simple Saver fabric liner system uses a strong, low permeance vapor retarder to create the required space for designed insulation thickness between the structural members while isolating conductive secondary framing members from the inside conditioned air.
