An attic ladder (US) or loft ladder (UK) is a retractable ladder that is installed into an attic door/access panel. They are used as an inexpensive and compact alternative to having a stairway that ascends to the attic of a building. They are useful in areas with space constraints that would hinder the installation of a standard staircase.
Rigid panel insulation, also known as continuous insulation [13] can be made from foam plastics such as polyisocyanurate or polystyrene, or from fibrous materials such as fiberglass, rock and slag wool. Rigid panel continuous insulation is often used to provide a thermal break in the building envelope, thus reducing thermal bridging.
Other materials used for fireblocking may include noncombustible materials such as gypsum board, cement board, or mineral fiber insulation blankets [2] [3] [4] Fire blocking is most critical in balloon framing, where a cavity may traverse multiple floors. More modern methods of platform-framing provide inherent fireblocking in most cases, since ...
A removable insulation blanket installed on a steam system component. A removable insulation blanket is a cover made from layers of thermal insulation materials that is fastened onto a mechanical component to maximize its efficiency, regulate its temperature, and improve workplace safety.
The final method of installing a radiant barrier in an attic is to lay it over the top of the insulation on the attic floor. While this method can be more effective in the winter [ 12 ] there are a few potential concerns with this application, which the US Department of Energy [ 11 ] and the Reflective Insulation Manufacturers Association ...
Glass wool batt insulation. Glass wool is an insulating material made from glass fiber arranged using a binder into a texture similar to wool.The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties.
This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
Low expansion foam expands less than 20 times its original size. These systems can be installed in a variety of places but are commonly found in places where hydrocarbons are stored. Low expansion foam systems when using film forming work by making a blanket of foam over the burning liquid to both cool it down and suppress the vapors.
