Glossary

It is the indicator that shows the flow of air that passes through the frame when it is closed. It is affected by the pressure exerted on the frame by the outside air. Finally, air permeability affects sound insulation.

It is an electrochemical surface treatment process to passivate aluminum. As part of this process, a thin layer of aluminum oxidation is created that is fully integrated into the outer surface of the profiles, thus offering remarkable features, such as aesthetics, shade stability, durability, ease of maintenance, health & safety.

It refers to the degree of difficulty offered by each frame in the event of a break-in.

It's the handle of the frame. It has two positions to lock and unlock the frame, while there is also a third retract position if the frame is tiltable.

Aluminum systems consist of an aluminum frame and a glass panel, with an application to replace a wall mainly in modern facades, forming an impressive glass appearance. Especially in skyscrapers, to save weight and exploit additional features, Curtain walls are used instead of masonry with a special technique of placement and installation on its aluminium frame.

It is the opening in the wall of a building that starts at the floor, unlike a window that starts at a certain height.

The tilt-and-turn frame (see tilt / tilt-and-turn) consisting of two leaves, one is either fixed or tilting and the other is tilt-and-turn.

It is a small hole (hole) made on the aluminum profile to leave the water that enters it. Covering plastic (drainage valve) is placed on top to cover the hole but mainly to avoid the possibility of the water coming out of the drainage returning.

The specialist handyman who undertakes the study of the openings in the space, the installation proposal with the appropriate aluminum system, the construction and the correct placement in the space.

A small space window (it can be located high up or serve in parallel for ventilation), is usually rectangular or semicircular and is placed above a door or another window.

Blinds are placed in a fixed position in a system, offering specific ventilation and shading conditions.

The component that allows closing an opening leaf without it locking and also without opening from the wind.

Frame that covers particularly wide openings and its characteristic is the complete or partial folding of the leaves to the side.

The folding door consisting of four or six sash respectively.

It is the frame that is firmly placed on the wall around the opening and allows the installation of the frame and its mechanisms. It is also called a frame track, as the frame either opens or slides on the case.

It is a structural element of the frame, which significantly affects its overall performance (e.g., air permeability, waterproofing, sound reduction). It is placed between the aluminum profiles and the glasses, as well as at the application-closing points of the sash with the frame.

It refers to the thickness of the glass placed in the frame.

It is the gasket that is placed around the perimeter of the glass, between it and the aluminum profile, to offer stability to the construction, to prevent any vibrations without breaking the glass, and to provide sealing from heat, water, air, and sound.

It is the total thickness of the panes of glass measured from the inside of the frame to the outside. The measurement method remains the same regardless of whether single, double, or triple glazing has been installed in the frame.

A lever commonly found on electric and heavy-duty rollers. In the event of a power cut, it raises or lowers the roll mechanically.

It is the transfer of thermal energy from a body/system of higher temperature to another of lower temperature. It is a natural phenomenon that happens either by heat conduction (between solid bodies) or thermal radiation (from a distance).

A component with two perforated levels that are placed one on the sash of the door, window, etc., and the other on the frame, while they are connected with a pin so that the door/window opens and closes freely.

It is the frame that has a special mechanism so that its sash move parallel to each other. The special mechanisms they have first lifts the sheet and then slides on guides.

Each of the small horizontal rectangular pieces of aluminum (or other material) that are part of a system (shutters or pergolas) form gaps between them that allow air to flow into the space.

It is a two-headed hammer, similar to a sledgehammer, that has a wooden or plastic head instead of an iron one, and is mainly used for minor corrections when installing frames without "damaging" them.

It is a combination of various components to achieve a specific function. For example, a frame lock mechanism is the set of components that combine to lock a frame.

It is the vertical structural element of the frame and usually the term refers to the central mullion, i.e., that part of the frame that appears when two sash intersect.

Thermal transmittance, (Uw for frame), is the amount of heat that passes through 1m² of frame. The lower the thermal permeability value, the better the thermal insulation offered by the frame.

It is the inner courtyard, the free open space roofed with transparent materials within the building. It has no specific shape or form.

It is a macromolecule produced artificially through step-growth polymerization or solid-phase synthesis. It is used as a produced profile after extrusion, to be placed between the aluminum profiles causing a thermal break.

The aluminum extruded product used in the composition and manufacture of an aluminum system.

It is the frame that opens at the bottom outwards. 

A small wheel used as a mechanism for rolling the sash of a sliding frame over the guide.

The louvres of a system which are usually electric (possibly also mechanical), can be moved, varying their position for ventilation or shading.

Part of the frame is distinguished as fixed or mobile. A sash is characterized as mobile when it can open and close (opening sash, sliding sash, etc.)

The cover is used for window frames and is usually openable or sliding. It offers shading, safety, and privacy.

It is the tilt-and-turn frame (see tilt / tilt & turn) that consists of a single sash.

It is the ability of a frame to reduce the intensity of sound propagation, either from the outside to the inside or vice versa.

It is a profile usually made of polyamide that is added between two aluminum profiles (so-called stitching of the profiles) in order to prevent Thermal transmittance.

It is the ability of a frame not to allow heat or cold to enter the interior or, respectively, the ideal conditions of the interior space not to exit to the exterior environment.

They are the frames that have a thermal break (see thermal break) and show high performance in thermal and sound insulation. Related Terms: Thermal break

It is a profile that goes into the bottom of the aluminum door. It contributes to the protection of the space, as well as to the overall performance of the frame in indicators such as sound insulation and thermal insulation. When the term "low threshold" is mentioned, it means a particularly thin profile of the profile, almost flush with the floor, also offering easier access.

The opening frame can take a retracted position, opening only its upper part, thanks to ventilation and space-saving.

The frame that offers the possibility of opening the leaf but also the possibility of withdrawal.

The frame opens internally or externally, depending on the mechanisms and needs.

The aluminum profile has not undergone any surface treatment such as electrostatic painting, pre-anodization, anodization, sublichromia, etc.

It is the indicator that shows that pressure point, where if exceeded then the frame will lose its waterproofness and water will pass inside the space.

This is the pressure exerted by the outside air on the frame. Important is the index of "resistance to wind pressure" which measures the deformation of a frame due to the pressure exerted by the wind.

It is an opening in the wall of a building, and unlike a door, it does not start from the floor but at a certain height.

It is the construction that fits into a wall opening and is intended to support the door or window mechanism. By extension, the frame is defined the whole of the door or window, i.e., the aluminum system, its components, and the glazing.

It covers the joint between the frame and the brickwork.
