A building site for a row of riverside apartment blocks in Cambridge. The buildings are being constructed using a systems build with a steel frame and various prefabricated components. The blue plastic on the central building is the vapour barrier for the thermal wall insulation before the exterior cladding has been fixed.
If the renovation is of a smaller nature, the renovation directive applies. Examples of renovation are post-insulation of a cavity wall and post-insulation of a sloping roof against the roof boarding or under the tiles. Note that every renovation must meet the minimum Rc value of 1.3 W/(m 2 ⋅K). If the current insulation has a higher ...
Thermal insulation is integral to greenhouse design, enabling controlled environments for plant growth and energy efficiency. Common insulation techniques include the use of double-layer films and multi-wall polycarbonate panels, which trap air between layers to reduce heat transfer while maintaining sufficient light transmission for ...
A district heating system uses centrally located boilers or water heaters and circulates heat energy to individual customers by circulating hot water or steam. This has the advantage of a central highly efficient energy converter that can use the best available pollution controls, and that is professionally operated.
Rastrick boiler: a vertical heat-recovery boiler, typically used in ironworks. Owing to the conditions of their use, they acquired a poor reputation for safety and explosions. [48] Reed boiler: An early naval water-tube boiler. [6] [9] return-flue boiler: flued boiler with a single large flue that folds back on itself. Used in early steam ...
A pipeline protected by wood lagging. Wood lagging is a method of banding wooden slats around pipelines to protect against impact, abrasion, and corrosion.Wooden lagging acts as a sheath, protecting the pipeline from damage, [1] and is especially useful in rocky terrain; steep inclines; around rivers or swampy areas; and other rough terrain.
