Lowfield Timber Frames invests in response to climate emergency

Mid Wales based timber frame manufacturers Lowfield Timber Frames (LTF) have seen a rapid increase in demand for passiv haus builds over recent years.

Having previously completed the first passiv haus social housing scheme in Powys, a new build primary school in Welshpool and a social housing development in Shropshire, the firm have secured even more passiv haus projects for the future including several schools and council led residential schemes.

In response to the climate emergency, and increase in demand for low carbon government buildings, LTF have invested in installing their own Warmcel insulation system which means that insulation can now be installed to the roof cassettes offsite during the manufacturing process, reducing the time working at height on site and avoiding possible site defects from insulating after installation. LTF are approved installers and have undertaken technical training to ensure they are experts with installation techniques and standards.

Warmcel insulation is a high performance insulation for timber framed buildings, sustainably manufactured from recycled newspaper. There is a natural fluctuation of moisture levels within a building that begins at the construction stage and continues throughout its lifetime. The hygroscopic properties of Warmcel insulation helps this moisture to naturally migrate to the outside of the building fabric without building up on structural elements.

Darren Jarman, Managing Director, LTF comments 'As well as thermal performance, our clients are really starting to understand the importance of a breathable, airtight building envelope and Warmcel ticks all the boxes.'

He continues, "As many of the main contractors start putting a greater emphasis on embodied carbon and the need for EPD's, Warmcel will become mainstream as we head towards Net Zero Carbon emissions and we are excited to be able to provide this offering in a factory-controlled environment."

LTF look forward to their partnership with Warmcel to provide an efficient solution to the ongoing climate emergency that will only see greater demand for passiv haus schemes in the coming years.
