Why choose NorDan for High-Rise developments?

With the need for social housing on the rise and land close to city centres becoming limited, the UK construction industry has seen an increase in demand for high-rise developments.

A crucial factor with high-rise projects is choosing the correct type of window that can provide a combination of weather resistance, energy efficiency, soundproofing, child safety, fire safety and low maintenance requirements.

Weather Performance & Durability

With the positive and negative wind pressures rushing up a building, this can drastically affect the operation of windows. In fact, there are many windows in the market that are even unsafe for use in high-rise developments. This is why you may see many architects steering towards fixed windows only on such projects.

However, at NorDan our inward opening StormGuard 3 handle tilt and turn window have many benefits for such projects. Our StormGuard window - like all our products - is designed in Norway to deal with the harsh climate and is tested to resist hurricane-level wind pressures.

With the 3 handles, this provides a tight weather seal tested to withstand wind pressure up to 197mph (4800pa), which is 8 times the UK industry standard of 600Pa. The NorDan window has smart 2-stage tightening profiles. Should any water manage to penetrate past the external glazing gasket, this window is designed with profiles that will drain water away and avoid any water build-up within the frame.

Quality & Energy Efficiency

With the tight weather seals, this also ensures that no draughts come in through the window and that your heat is not escaping. Our high-quality double glazing can also help with energy efficiency and sound reduction.

NorDan double glazed window and door products offer U Value 1.2W/m2K and 37dB sound reduction as standard performance with a centre pane Glass U value of 1.0W/m2K. Current building regulations state a minimum performance of 1.6W/m2K meaning that our double glazing is extremely high performing.

There’s also the possibility to upgrade to even higher-performing triple glazing. This offers U-Values as low as 0.7W/m2K. Additionally, acoustic properties can be improved to approximately 41dB.


These windows can be provided to suit your needs, with handles that are either removable, locking or even blanked off for safety purposes. Other options include the supply or windbreaks or child restrictors that will be suitable also in residential buildings.

The unique seven-point locking system on our StormGuard window is part of the reason the sash can take a load weight of up to 100kg. A bonus, with the window being inward opening, is the functionality to safely allow cleaning and maintenance from the inside of the property.

Though break-ins aren’t a big concern for the top-level windows, those with offices or apartments at the ground level of a high-rise would also be reassured that all NorDan’s products have ‘Secured by Design’ accreditation.

The NorDan Difference

Of course, there are many window products on the market – but none with the performance capabilities of a NorDan product for high-rise developments.
