Guardian SunGuard® Glass is a Smart Choice in Educational Facilities

Because of their purpose, they must meet the highest safety standards while also ensuring the comfort of the occupants.

One of the ways to improve comfort inside educational institutions, especially those in historic buildings, is to use glazing with high transparency and an optimised solar protection. Zamek Culture Centre in Poznań is a building where such a solution has been successfully implemented.



The Imperial Castle in Poznań is one of the most famous and respected facilities in the capital of the Wielkopolska Region in Poland. This enormous building with a vast history now houses the Zamek Culture Centre and serves as a popular venue for numerous events in the field of music, theatre and literature. It regularly holds educational lectures, workshops, group meetings and clubs for children and youth.

For all of its visitors, the centre is focused on providing a comfortable, functional and safe environment despite the limitations resulting from its historic architecture. That’s why the planners replaced the old windows with new ones using energy-efficient Guardian SunGuard® SuperNeutral 62/34 architectural glass.

Into the future



Allowing an adequate supply of natural light into the interior is a key requirement for windows in educational institutions. In the case of historic buildings this can be particularly difficult to achieve because, while the interiors are usually high and spacious, windows tend to be relatively small and divided into multiple smaller panes. Zamek Culture Centre in Poznań addressed this problem by using windows made of Guardian SunGuard SN 62/34 glass.

This product provides not only a high level of natural light transmission (up to 62%), but also an excellent solar protection. This effectively means that with an appropriate level of brightness during the day, there is no need to use artificial lighting in the castle’s interiors. Moreover, no curtains, blinds or shutters are needed to shade the rooms on the sunniest days. Another important flaw of historic buildings such as the Zamek Culture Centre is their low thermal insulation, which inevitably leads to heat loss.



Replacing old windows with more modern, energy-efficient counterparts can minimise this problem and provide optimal indoor temperatures. Architectural glass SunGuard SN 62/34 is characterised by a very good thermal insulation (U = 1.0 W/m2K), which helps to reduce the risk of so-called thermal bridges in the interiors and minimise heat loss in the autumn and winter seasons. The high selectivity of Guardian® glass products ensures optimal thermal comfort also on hot, summer days. Treated with a multifunctional coating, SunGuard SN 62/34 has a ‘g’ value of 0.34, meaning it allows as little as 34% of solar energy transmittance inside the building and effectively protects the interior from overheating.
