GLASS SELECTION

GLASS SELECTION

Glass and frame: a critical marriage.

ThermalHEART™ thermally broken aluminium window and door systems are designed to accept double glazing as standard. Using double glazing in ThermalHEART™ thermally broken aluminium window and door systems will enable you to maximise energy efficiency and comfort. Performance glass can help to overcome site limitations, so views and natural light can still be enjoyed without compromising energy efficiency. You can also combine energy-efficient glass with other options, including glass that reduces noise, provides protection from intruders, and creates shelter from extreme weather.

The performance of ThermalHEART™ thermally broken aluminium window and door systems combined with the right glass selection is a vital part of the building envelope and ideally should be considered early in the design process. Getting the glass selection right in the design stage can help make a project run more smoothly and allow you to take advantage of the most effective solution.

There are three main areas to consider when thinking about glass selection: natural light, solar heat gain, and thermal conductivity.

Natural Light

One of the advantages ThermalHEART™ thermally broken aluminium window and door systems bring to commercial buildings is the ability to incorporate large expanses of glazing in building façades while still achieving Section J code compliance. The right performance glass, combined with ThermalHEART™ window and door systems, allows you to make the most of views and natural light while controlling UV and glare.

Solar Heat Gain

ThermalHEART™ thermally broken aluminium window and door systems minimise heat gain through the window frame. Coupled with the right performance glass, buildings are able to harness the natural warmth of the sun during winter, and lessen its impact during summer. Choosing the right performance glass in commercial buildings is critical due to the typically large ratio of glass to floor area.

Thermal Conductivity

ThermalHEART™ thermally broken aluminium window and door systems insulate the building envelope against heat loss and gain through the window frame. To maximise this effect, our ThermalHEART™ window and door systems accept 24mm Insulated Glass Units (IGUs) as standard. Monolithic glass can also be used in ThermalHEART™ window and door systems. Durable hard coated Low Emissivity (Low E) coatings significantly improve the insulating properties of standard glass.
