active roofs
How to benefit

Constructing an Activity Roof requires an initial investment and there are pitfalls to consider during the design and construction phase. Still, it’s a smart choice.

A smart choice

 Here’s why:

  • Space is a scarce commodity. An Activity Roof makes optimal use of that limited area. Additional space can also help to optimise the organisation of the building.
  • An active roof is usually on top of a building. However, it can also be a roof of an underground car park. So a roof on level 0 with extra space for a park, playground, sports field, ... 
  • As many governments are rethinking the way they will shape future cities, new regulations and recommendations will be issued. Roof activation is expected to play a crucial role in this. By installing the correct build-up now, you can comply with new regulations in the future, without additional costs to prepare your roof surface.
  • Building an active roof based on the FOAMGLAS® Compact Roof build-up offers you flexibility in the future. As your needs change, so can the functionality of your roof. One day, you could have a rooftop terrace with urban farming, the next day a tennis court or a parking deck. Whatever the future brings, it’s feasible on your rooftop.
  • An Activity Roof adds value to its users and to the urban environment. This will be reflected in increased rental or selling prices. A definite return on investment.
  • An Activity Roof can be a source of income. Think of a car park, an energy roof or renting out the space for telecom masts. The possibilities are endless.
  • Activated roofs are gaining popularity and are increasingly being implemented in cities that are intentionally seeking to build a sustainable future. This trend is set to continue strongly between 2025 and 2030, with an expected growth of 8% in market size. You can be a frontrunner, pushing the trend forward. Set the scene for others to be inspired!
  • You will contribute actively to creating more sustainable cities, where community life is valued and the effects of climate change are addressed. You will also help reduce risks of flooding and urban warming, helping to clean the air we breathe.

Meet your partner in crime

Once you have decided to integrate an Activity Roof in to your next building project, consider carefully what products and solutions you will work with and which partner can offer you the peace of mind that is essential to any building project. As established experts in the flat roof market, we are your perfect partner in crime. 

Here's why:

  • When it comes to the build-up of your Activity Roof, no compromises should be made. Our experienced FOAMGLAS® technical team is there to guide you through your project, every step of the way. A premium service that is part of the deal. We’ll do whatever it takes to remove your worries.
  • The FOAMGLAS® technical team is there from start to finish. As an architect, you can count on their expertise during the design phase of the building, with expert advice, technical documents and drawings. As a contractor, you and your team will receive practical training, expanding their knowledge and skills, which could prove invaluable in the future. Our team will be right by your side on the jobsite during start-up, making sure everything runs smoothly.
  • By constructing an Active Roof based on the FOAMGLAS® Compact Roof build-up, you have the option to discuss favourable insurance fees with your insurance companies. As FOAMGLAS® is an incombustible and 100% water resistant product, it greatly reduces the risk of any damage to your rooftop, decreasing the risk for your insurance company.
  • Correct water evacuation is a challenge for any building project, especially in Active Roofs. FOAMGLAS® TAPERED is a more than convenient solution. It integrates water evacuation directly into the insulation rather than into the structure of the building. Our team of experts calculate the perfect slope for your surface, taking all aspects of your project into account.

FOAMGLAS® TAPERED is a high-quality insulation and water evacuation solution in one; a cut-to-fall insulation system. Our FOAMGLAS® TAPERED insulation layer adds water evacuation directly into the insulation rather than the structure of the building. This results in less concrete and a lighter load, saving considerable time on the job site and reducing the risk of an incorrect execution.

Unlike alternative insulation solutions, the gradient of FOAMGLAS® TAPERED can be reduced thanks to the exceptional combination of properties such as compressive strength, dimensional stability and water tightness.

Proper drainage and watertight insulation alleviate the risk of any future leaks, guaranteeing a long lifetime with no standing water.

The high compressive strength will prevent any deformation, with no risk of flaws or damage.

How does our FOAMGLAS® TAPERED service work?

Our sales engineer will cooperate closely with you, making sure all details needed to design the tapered surface for your project are perfect. This includes information about the circumference of the surface, sills, eaves and the height restrictions of the roof and water drains. The slope, optimal discharge direction and desired thermal performance are also discussed.

The perfect slope for your surface is calculated, taking all aspects into account.

Our expert TAPERED studies team will then guide you through every step of the process, examining all of your needs and taking into account every single detail of your project. They will provide you with visual drawings and a detailed installation plan for a high-quality insulation solution that will stand the test of time.
