Let there be light |
Solar Heat Gain is mainly a positive effect associated with your roof glazing. All year round our patent glazing systems will allow free light and heat to enter into your building or home. The sun's natural rays of light will improve the quality of your working and living area as well as lower your central heating bills during the daylight hours. |

Heat and Glare Reduction The designers of large factories and mills in the 19th and 20th centuries were aware of the need of free light during daylight hours to lower the need of artificial lighting. Glare would also be a problem if the factory workers were exposed to this. Northlights became the best solution. Large areas of glazing were introduced into buildings which were not subjected to the intense power of the sun. They were positioned to face in a northerly direction and had a steep pitch of usually 60°. Inelligent positioning of your roof glazing is the first priority for new build projects. If your roof glazing is planned to be south facing then we recommend using a high performance solar control glass that reduces heat and light transmission or to incorporate internal blinds that can be used when the sun is too overbearing.

Solar Shading Devices/Blinds/Louvres IMPORTANT NOTE: Close fitting Blinds must NEVER we installed underneath roof glazing if the inner pane of glass is a LAMINATED type. You must always use a toughened glass or a special (and significantly more expensive) heat strengthened laminated composite to prevent the high possibility of thermal fracturing occuring to the laminated pane. We have also regularly applied a factory fitted anti-shatter film to toughened glass for use in schools where blinds will be used in close proximity to the glazing and where toughened glass is not desired as an inner pane. If you do not wish to use blinds on south facing designs then your glass choice should be considered carefully. We would recommend using a high perfomance solar control glass that blocks at least 50% of light from entering the building. Please note that glare will still be an issue at certain times of the year. External Blinds/Louvres |

Ventilation This is not a one step cure and would only help to maintain an internal temperature similar to the external temperature within your room if the roof glazing is exposed to direct sunlight. It is recommended that ventilation combined with the use of solar control glass and/or solar shading devices will always provide the best results in creating a comfortable internal environment for the building user.
