To better understand the terminology that is frequently used within Alumasc Facades, we have collated some into an online glossary. Below, you will find concise explanations of a number of measurements, products and materials to help increase clarity surrounding facades language.
Bedding adhesive – sometimes referred to as bedding mortar, a mixture of sand and cement used to pave tile and stone.
BIM – an abbreviation for Building Information Modeling.
Cavity wall – a wall constructed by two masonries, often brick or concrete, with a space in the center of the two.
Cladding – a substance added to cover the exterior of a structure.
Condensation – water vapour from the air condenses when it meets a cool surface.
Conduction – a transfer of thermal energy (heat) through an object, e.g. a metal that heats up.
Convection – a transfer of thermal energy (heat) through gases and liquids, e.g. the air.
Density – how compact a substance is.
DPC level – damp-proof course; a barrier in a wall that resists rising moisture.
Drained cavity – a cavity wall in which moisture drains out of the cavity to protect the structure of the building.
Dual density – a quality that involves the outer layer of insulation being of a higher density than the rest of the product. Possessing dual density allows minor imperfections in the substrate to be covered, and for an ideal application of render and/or brick slips.
EPS – expanded polystyrene. This low-cost material is used as insulation for its high thermal efficiency and resistance to heat flow.
External wall insulation – insulation installed on the exterior walls of a building or structure to increase its overall thermal efficiency.
Impact resistance – how a material resists fracturing to some form of external force.
Internal wall insulation – insulation systems applied to the interior of a building or structure, usually using a stud wall.
Masonry paint – the paint used to cover render to give it an aesthetic finish.
Mineral wool – made from molten glass which is spun to create a fibrous material used as insulation.
Permeability – the measure of how capable a substance is of being able to pass fluids through its structure.
Pointing mortars – a substance used to fill gaps between bricks to secure brickwork or other masonry structures.
PSI value – how much heat is able to escape from thermal bridges within the structure of a building.
Radiation – the transfer of thermal energy (heat) that requires no means of contact in order to be transferred; it occurs through empty space.
Render – the decorative finish applied to the outer layer of EWI systems. Render is available in many colors and textures.
SAP – an abbreviation for Standard Assessment Procedure. This procedure assesses and compared the environmental and energy performance of buildings.
Tensile strength – how much resistance a material can withstand before it breaks.
U-Value – a measurement of how well a material performs as an insulator.
Y-Value – a measure of the amount of heat that can escape through junctions within a building’s structure.
