Creating Products With Sustainability in Mind

Product sustainability

How we are maintaining the performance of our solutions whilst supporting the environment

The principal function of a roof is to protect buildings and people but a flat roof can also provide a huge range of sustainability benefits. By incorporating insulation, modern, sustainable flat roofs can improve thermal performance and reduce the energy consumption of a building. Not only that, they can provide biodiversity, amenity space and urban cooling through the addition of a green roof, renewable energy generation in the form of a solar photovoltaic array, and adding a blue roof can provide sustainable urban drainage systems (SuDS).

At a product level we are looking at modern ways to maintain the performance of our products whilst supporting the environment. This embraces elements not only for recycled content and recyclability at end of life, but also responsible sourcing for raw materials that minimise embodied carbon and the use of fossil fuel derivatives.

Product pillar of our company sustainability

Utilising biomass balance in the production of our ECO FF insulation

Our BauderECO FF flat roof insulation is manufactured largely from biomass waste comprising residues from agriculture (plant stems, plant leaves, threshed corn cobs etc); recycled materials from our manufactured PIR offcuts (approximately 1%); and calcium carbonate from natural shell waste from the food industry to incorporate with a glass fleece for the board's facings.

BauderECO FF is used within a warm roof construction for a heat/conditioned building on both new build construction and refurbishment of existing flat roofs.

Selected by clients seeking to meet carbon reduction goals for sustainability, commercial and a net zero carbon roadmap across their supply chain for construction and ongoing maintenance of flat roofs on buildings.

Currently, two of our waterproofing systems have been tested with BauderECO FF and are available for specification.

Bauder Total Roof System - reinforced bitumen membrane system
Bauder Thermofol PVC - single ply system

Recycled content in our products

Working closely with our suppliers and using data from extensive research, we have steadily increased the recycled content of many of our products without detrimental effects on their durability, performance, or longevity of service.

Our principles are to focus on lifecycle and deliver systems with extended life expectancies rather than compromising on quality by producing lower grade membranes that would consequently require replacement sooner.

Single Ply Membrane production includes recyclate to the base layer.

Hot Melt Waterproofing has recycled content incorporating post-consumer recycled rubber.

Green Roof Components contain recycled and waste materials. For example:

Water Retention and Drainage Layers - Our DSE 20, 40 and 60 boards all utilise 100% recycled high-density polyethylene, moulded to create the cupped profile boards that provide water retention and multi-directional drainage
BAUDERGREEN RWR 100 - This board is manufactured from 100% recycled Polypropylene
Protection Layers - Our FSM 600 and 1100 are made from a mixture of 100% recycled reground polyester and polypropylene fibre, which are combined before being mechanically and thermally solidified to create a layer to prevent mechanical damage to the waterproofing
BAUDERGREEN GGM 6 - used for intensive green roofs, is made of 100% granulate from recycled shredded tyres reformed and bound by Polyurethane to give a protective layer against mechanical damage
BAUDERGREEN SV 300/600 - is a protective layer created from 100% recycled Polyester clothing and fabric
Substrates and Growing Mediums - Our peat-free substrates contain a minimum of 95% recycled content including crushed brick and composted organic material. Our growing mediums balance water storage, structural stability, water permeability and grain size distribution to meet the requirements of the planting scheme

Environmental Product Declarations (EPDs)

An EPD measures the environmental impact of a product, and the declarations quantifiably demonstrate the environmental performance of products.

EPDs give transparency about product's environmental impacts and its sustainable aspects in a single comprehensive objective report and are valuable to specifiers to support decisions made at specification stage for the products to be used on a flat roof solution. EPD support building assessment schemes such as BREEAM.

Integrity Next

Evaluating supply chains can be an enormously complex and time-consuming procedure. In order to simplify and quantify our commitment to a secure and sustainable supply chain Bauder have partnered with Integrity Next.

Integrity Next provide a simplified platform that enables us to ensure we are protecting human rights and environmental matters in our supply chain whilst enabling our clients to quickly oversee our sustainability activities for our Bauder manufactured products.

BauderECO FF: when biomass becomes flat roof insulation for a sustainable future

Our first step towards a sustainable future without compromising the quality and established long-term performance of our PIR insulation is in BauderECO FF.

Utilising the biomass balance approach, our ECO FF insulation is manufactured from 80% biomass-based raw materials. This is the start of our journey towards removing the use of fossil raw materials in Bauder insulation products.

Embodied carbon

Low embodied carbon compared to standard PIR insulation that uses 100% raw material from conventional fossil fuel derivatives based on the biomass balance approach. ECO FF is manufactured using renewable raw materials derived from biomass waste and residues from, for example, agricultural production, crop or food processing.

Certification

ECO FF holds REDcert² sustainability certification: REDcert²-904-39352401. This is third party auditing for the use of sustainable materials in the chemical industry. This is for the chemicals used to make this PIR insulation and the finished product itself.

BBA certification is in progress to verify our performance data and, upon successful completion of testing will be added to our current PIR certificate.

Achieving thermal performance

The flatboards are available in three thicknesses to meet different thermal requirements or U-values.

125 mm achieves an approximate U-value of 0.18 Wm²K.
160 mm achieves an approximate U-value of 0.14 Wm²K.
205mm (two boards 125 + 80mm) achieves an approximate U-value of 0.11 Wm²K.

Waterproofing compatibility

The ECO FF insulation has been tested and can be incorporated in to warm roof construction when specifying our Bauder Total Roof System including the system’s green roof scenarios, and Bauder Thermofol PVC single ply system.

Fire performance

ECO FF has the same fire performance of our conventional PIR insulation.

Use within green roofs, biosolar and solar PV solutions

Specifying ECO FF is easy for all these solutions, particularly within our BTRS system where the BauderPLANT E root resistant cap sheet will be incorporated for all green roof and PV solutions. If weight loading is a factor for the project, then the Bauder Thermofol PVC system for extensive green roofs, biosolar and solar PV is a consideration.

Bauder solutions for sustainable rooftops

To ensure all flat roofs maximise the roof space to support the environment, it is important to consider how a green roof, blue roof, solar PV and insulation can be incorporated into a new build construction.
