Bigger windows, of course, admit more daylight, but it is also worth considering more smaller windows as a better overall effect can be achieved. Using one roof window would allow daylight to light approximately 46% of this room. Using two roof windows with a combined total surface area of the previous window would allow daylight to illuminate approximately 48% of this room.
Four roof windows with the same combined total surface area distributed more evenly would allow daylight to illuminate approximately 65% of this room!
You can also admit more light into the room by using the correct lining. If the lining is vertical below the window, and horizontal above the window, you allow more light to enter the room.
If incorrectly splayed, warm air is trapped and may cause condensation. When correctly splayed, warm air circulates freely around the room.
Before deciding on a particular size of the window, the structural integrity of the roof should be considered fully. Most roofs can be adapted to take roof windows but some engineered trusses should not be cut without a proven solution. If you have any doubts which beam to cut, we recommend seeking professional advice before commencing work.
What to consider to maximize light from your roof windows:
In addition to internal light and design, you should also consider what visual impact the roof windows will have on the outside of your house. Consider the roof windows’ position in relation to existing windows in the house. Then try to balance the need for internal light with the external architecture. By doing this your roof windows will look elegant from the outside and perform according to your needs on the inside.
A roof window should always be placed at the correct height and be of the right size to suit your specific needs. Choosing the correct window size has to do with the roof pitch on your house. If you have a low roof pitch you need a larger roof window height to have the same view as in a house with a steeper roof pitch. A general rule is therefore that “the lower the pitch of the roof, the higher the roof window”.
In addition to the size of the roof window, you should also consider in which height to install the roof window. It is important that most occupants in the house have a clear view out the window.
There is no one single “correct” window size or window placement. The window should always be placed for the convenience and functionality of the users, and this can vary according to the conditions. For the same view, a shallow pitch roof requires a taller window than a roof with a steeper pitch.
Wear suitable protective equipment during installation. You can normally complete the installation of a roof window from the inside of the house, and scaffolding is therefore not considered necessary. However, as with all construction, there is a risk that objects might be dropped from the roof (hammer, tiles, etc). We, therefore, recommend that you never leave any object resting on the external face of the roof and that any area at risk should be sectioned off to minimize the risk.
It is recommended that you wear safety masks and goggles, when cutting any internal materials in the roof or when cutting tiles. Furthermore, it is also suggested using temporary support battens whilst placing the window frame.
Roof windows require little care – just the ordinary cleaning of the pane and a yearly re-lacquering of the wood if installed in rooms with a high level of humidity. All roof windows rotate up to 165 degrees to facilitate easy cleaning of the external pane. Moreover, Dakea Ultima and Dakea Best PVC ranges come with a care-free Titan Glass coating.
Titan Glass glazing unit offers an unparalleled reduction of dirt builds upon the external surface of the window.
During the manufacturing process of the glazing, a special microscopic titanium dioxide coating is applied directly to the surface of the glass. When exposed to sunlight, this titanium coating triggers a dual-action process:
Titan Glass enables faster drying – leaving the glass clean and with reduced streaks, which gives you beautifully clear views and makes it ideal for all the exterior glass surfaces in your home.
You can also clean the wood with hot soapy water, but please note that too frequent cleaning may increase the need for re-lacquering the wood.
The need for re-lacquering depends on the humidity in the room. You can use any type of water-based lacquer – but please make sure it is applied evenly.
Grease the center hinges to ensure a smooth rotation of the window. Clean around the gutters on the window to ensure a free flow of rainwater around the window.
The blinds do not need regular maintenance. All you need to do is to clean the blinds with a damp cloth when you see a need.
We recommend that you periodically clean the gutter and the area around the roller.
You do not need regular service for your roller shutter to keep it working. Just use common sense and it will last you for many years.
You can clean the motor with a damp cloth using normal detergents.
There is not much maintenance needed for your electrical opener. We only recommend that you grease the chain once a year to increase durability and keep the chain running smoothly.
