RoofKrete

Refurbishment

The government is committed to reducing carbon emissions in new construction by setting requirements for the control of air leakage, regulations in thermal bridging, and specific thermal performance measures within The Building Regulations Approved Document 1, and Scottish Building Standards Agency (SBSA) Technical Documents Section 6. However new build represents less than 2 % of the build environment annually, so the only real quick solution to reducing co2 emissions is to focus on refurbishment of our existing buildings.

Upgrading the thickness of thermal insulation at roof level will, in most cases , reduce future carbon emissions, and reduce the energy bills of existing buildings, which through heating and powering are responsible for over 300 million tonnes of co2 emissions every year. Renewables and green roofs can also be installed on many existing buildings further improving their environmental performance.

RoofKrete and all the Krete products are ideally suited to roof refurbishment, having no heat and no flame installation—they are cold applied., And are lightweight and vapour permeable.

Whether it be new construction or refurbishment the same factors need to be considered when evaluating the environmental performance of roofing membranes, including—

• LONGEVITY - a key function is Durability
• RELIABILITY IN USE - the quality of trained contractors for installation is vital
• MAINTENANCE - a potentially ongoing impact - Roofkrete / Krete is however "Fit and Forget" - with virtually no maintenance.
• LOCAL PRODUCTION - if you specify say a product made in Switzerland (e.g. PVC or TPO) the embodied energy of 800 km of transport/ diesel is enormous
• EMBODIED ENERGY - it is essential to specify a low embodied energy product
• NO FOSSIL FUELS - if petrochemical products will run out in less than 40 years, it is obvious that if non-oil based products are available and affordable, then replace
• WASTE DISPOSAL - try to find a replacement product that can be laid on top of the old existing roof, avoiding Land Fill.
