| This will also occur on pipework lagged with an open cell insulant. |
| A simple insulant has too low a mass and so cannot store the heat. |
| The passage of hot gases through the insulation and their development inside the insulant is to be excluded. |
| High-grade insulant made of recycled material, oil and water repellent. |
| In order to perform effectively as an insulant a material must restrict heat flow by any of the three methods of heat transfer. |
| The glass fibers are so fine that the thousands of tiny air pockets they create strengthen the resistance of the insulant to heat transfer. |
