Thermal bridging can be reduced through correct installation of insulation, and by using insulating features such as sheathing on the outside of studs or using thermal breaks in aluminium glazing.

How insulation works Insulation works by providing resistance to heat flow.
On this page: Where heat is lost R-values How bulk insulation works Reflective insulation Thermal bridges Insulation slows heat losses from a building, typically by using bulky, lightweight materials such as glass-fibre or polystyrene between framing elements. Process heating is a critical factor in many manufacturing processes and contributes to the overall cost of operation.
Insulation helps minimize heat loss in these application, but often, insulation and its role in energy efficiency are not considered during the design phase. Yet after construction, adding or increasing insulation thickness may be difficult. Using a less efficient heating system is like throwing energy dollars out the window. In addition, insufficient insulation can jeopardize worker safety as well as product quality.
It also can lead to increased greenhouse gas emissions and damage to temperature-sensitive equipment. Process, industrial or application engineers typically will outline a flow diagram to describe the process requirements. Equipment specific to the manufacturing process is planned along with any material-handling requirements to move material from one area to another.
When the process requires heating material, calculations are made to consider:. Insulating jackets can be standard or custom fitted shapes. Any time heat is transferred to a mass other than as intended, it is considered heat loss.
Heat loss can result from:. A major source of heat loss is poor insulating practice. This can be insufficient thickness, but more often, it is the result of damaged insulation figure 1. Important items to look for during insulation inspection are:. In some cases, further investigation — for example, removing coverings or the insulation — is needed to identify the underlying problem.
Polyimide fiber is a more durable alternative to fiberglass. Material selection is a critical component to energy efficiency. Different materials and thicknesses impact efficiency by reducing heat loss.
Application temperature, installation, environment and durability are vital considerations. All of these materials can be applied directly over piping or flow-control components, and some can be used in formed insulators with covering material. Fiberglass, aerogel, polyimide fiber and silicone sponge can be used in all-in-one heated insulating jackets. If the insulation will be removed and reinstalled in the same location, the chosen insulation should be durable and easy to handle. Thermal conductivity ratings for a number of materials are shown in table 1.
Heating jackets are insulators with built-in heating wire, the jackets may include covers of different materials. Covers are used to prevent UV degradation, unintentional damage, moisture permeation or environmental wear. Fiberglass mat can be cut and wrapped around pipe, components or vessels.

If you know how your home's insulation works, you can also understand what makes it malfunction and contribute to poor energy performance in a house. Here's what can go wrong:.
Slowing the transfer of heat is just as important in hot weather as it is during cold weather. So even though the down jacket example focuses on insulation's role in keeping a house warm in winter, the same principles apply when it's hot outside and you want to save money on air conditioning. All insulation shares a common measuring unit known as R-value. The "R" stands for resistance to heat flow.
A high R-value means greater resistance to heat flow and thus, greater insulating value. R-value is described both in R-value per inch and in total R-value. Our team of experts and professionals are more than willing to assist with your insulation queries or provide advice whenever you need it!
