Question 1

The primary function of a window is to&#10;A) Enable cleaning from the inside of a building&#10;B) Allow daylight into the building&#10;C) Provide a view of the external environment&#10;D) Enable the building to be ventilated&#10;E) Provide an escape route in a fire

Accepted Answer

The primary function of a window is to allow daylight to enter a building. While it may also provide a view of the external environment and enable ventilation, these are secondary functions. Cleaning from the inside and providing an escape route in a fire are not primary functions of a window.

Question 2

The thermal performance of windows may normally be improved by&#10;A) Increasing the area of the window&#10;B) Using metal frames&#10;C) Using tinted glass&#10;D) Using multiple glazing&#10;E) Using vertical sliding windows

Accepted Answer

Using multiple glazing, which involves using more than one layer of glass with a gas-filled space between them, can significantly improve the thermal performance of windows by reducing heat transfer through the glass. This can help to lower energy costs by reducing the need for heating and cooling in a building. Increasing the area of the window, using metal frames, using tinted glass, or using vertical sliding windows may offer other benefits such as increased natural light or improved ventilation, but they may not have as significant an impact on the thermal performance of windows.

Question 3

One advantage of timber windows is that they&#10;A) Are galvanised&#10;B) Have low moisture movement&#10;C) Have low cost&#10;D) Have high durability&#10;E) Provide maximum daylight admission

Accepted Answer

C

Question 4

One disadvantage of aluminium windows is that they&#10;A) Are easily damaged&#10;B) Have low durability&#10;C) Have low aesthetic appeal&#10;D) Are supplied factory glazed&#10;E) Have low thermal conductivity

Accepted Answer

Aluminium windows are known for their durability and high aesthetic appeal, but they can be easily damaged during installation or by impact. They are also supplied factory glazed, which is not a disadvantage. Aluminium has high thermal conductivity, which can be a disadvantage in terms of energy efficiency, but this is not one of the options provided.

Question 5

The transom in a casement window is a&#10;A) Horizontal member separating the casement sash from the ventlight&#10;B) Vertical member separating the casement sash from the ventlight&#10;C) Vertical member separating the fixed light from the ventlight&#10;D) Horizontal member separating the fixed light from the ventlight&#10;E) Vertical member separating the casement sash from the jamb

Accepted Answer

The answer of The transom in a casement window is...

Question 6

The main difference between a modified casement window and a standard casement window is that in the former&#10;A) The fixed lights are framed with rails and stiles&#10;B) The opening casements are rebated&#10;C) The fixed lights are glued into the frame&#10;D) The transom extends beyond the face of the frame&#10;E) The sill extends beyond the face of the frame

Accepted Answer

In a modified casement window, the opening casements are rebated, meaning they overlap with the frame to improve their sealing capability. This is the main difference from a standard casement window, where the opening casements typically close flush against the frame. The other options (A, C, D, E) are not defining characteristics of a modified casement window.

Question 7

PVCu windows are fixed by&#10;A) Galvanised steel fixing straps fixed to the inner leaf&#10;B) Building the window in as the external wall is constructed&#10;C) Bolting the window to the pressed steel lintel&#10;D) Gluing the window into the timber sub-frame&#10;E) Screwing into the cavity closer

Accepted Answer

PVCu windows are typically fixed using galvanised steel fixing straps that are screwed to the inner leaf of the masonry. This ensures a secure and long-lasting installation. Building the window in as the external wall is constructed can also be a good option, but it requires planning and coordination with the construction team. Bolting the window to the pressed steel lintel is not recommended, as it can cause damage to the lintel and compromise its structural integrity. Gluing the window into the timber sub-frame is not a reliable method of fixing, as the glue can deteriorate over time. Screwing into the cavity closer is not a recommended method, as it can cause damage to the insulation and moisture barrier.

Question 8

A vertical DPC is fixed to&#10;A) A mortice in the reveal&#10;B) A throating in the sill&#10;C) A rebate in the head&#10;D) A slot in the horn&#10;E) An anti-capillary groove in the jamb

Accepted Answer

A vertical Damp Proof Course (DPC) is typically fixed to an anti-capillary groove in the jamb to prevent water from traveling across the DPC and entering the building. This groove acts as a barrier to capillary action, which can draw water upwards or across materials.

Question 9

Low E glass is beneficial because it allows&#10;A) High frequency sounds from the road to be blocked from entering the building&#10;B) Long wave radiation from the building to exit&#10;C) Short wave radiation from the building to be blocked from exiting&#10;D) Long wave radiation from the sun to be blocked from entering the building&#10;E) Short wave radiation from the sun to enter the building

Accepted Answer

Low E glass allows short wave radiation from the sun to enter the building, which helps in heating, while reflecting long wave radiation back inside, improving energy efficiency.

Question 10

Glazing is normally fixed to steel windows by means of&#10;A) A mastic sealant&#10;B) Linseed oil putty&#10;C) Putty with a hardening agent&#10;D) Glazing bars&#10;E) A silicone gasket

Accepted Answer

The answer of Glazing is normally fixed to steel windows...
