Group approach to sustainability
Creating long-term value and making a positive impact on people are key to the SIG Group approach, while also balancing the fast-changing environment of regulation.
In 2021 SIG released our 5 Sustainability Commitments which set out our top-level approach to sustainability.
These are:
- Achieving net-zero carbon by 2035.
- Sending zero waste to landfill by 2025.
- Partnering with manufacturers and customers to reduce carbon and waste across the supply chain.
- Health and safety leader in building materials distribution.
- Being an employer of choice in our sector.
Sustainability Commitments
At AccuRoof, we fully subscribe to the 5 commitments, actively working to ensure they are integrated across our organisation.
To read more about our approach and performance in sustainability, including our health and safety performance, please refer to our website to download the latest documents and additional reports can be found in the sustainability section. Our ESG performance is reported in our Annual Report and additional reports can be found in the sustainability section.
Steps to Flat Roof Sustainability
By taking a holistic approach to roofing design from the start, AccuRoof can assist in maximizing the contribution that the roofing element of your project makes towards your sustainability goals.
In spatial terms, flat roofs can be highly efficient. They reduce the apparent mass of a building and provide easily accessible space for services, such as HVAC plant and photovoltaic panels. Flat roofing insulation can provide a significant contribution towards the energy efficiency of your project. Terraces, green roofs and roof gardens can also enrich the ‘fifth elevation’, providing an important amenity for building occupants.
In addition, a green roof can
- Facilitate carbon capture
- optimize the structural footprint of the building
- assist with urban drainage
- enhance thermal and acoustic insulation
- increase a membrane’s life expectancy
- provide green amenity space
- absorb airborne pollutants and
- counter the heat island effect in cities.
As part of AccuRoof’s holistic approach, we can help you choose the right products that meet all your project’s criteria, including your sustainability requirements.
We can help you consider various factors including:
- local materials sourcing and production
- recycled materials and recyclability
- full lifecycle assessment
- solvent and VOC content
- zero waste packaging
- product lifespan and durability
Detailing practices, future maintenance and whole life costings must also be considered when discussing sustainability.
For specifiers, talking to a roofing specialist at the earliest opportunity can help you specify the right products and systems, and meet any key detailing and compatibility challenges.
For clients and end users, it’s vital that flat roofs are subject to a regular inspection, making sure drainage outlets remain unblocked and appropriate repairs or replacement can take place if needed. Prioritising maintenance will help your flat roof achieve or exceed its life expectancy.
Clients should also consider the design life of the building, the whole life costing of the waterproofing systems and choose appropriately durable products; where necessary, building a reroofing strategy into whole life costs.
