Large Building Mushrooms with Cemsix

Cembrit’s Cemsix corrugated sheeting has provided a high quality roofing and façade material for a large-scale agricultural building in Hampshire. The impressive-sized building features a 5° low pitched roof and is the largest installation of Cemsix in the UK. Supplied in olive green, Cemsix cover 4000m2 of roof with another 2000m2 of façade and provides a durable and weatherproof material that blends seamlessly into the landscape.

The building is owned by Tunnel Tech Ltd, a compost business established in 1985 and the largest supplier of mushroom substrate in the UK. Located on the large Leckford estate, the building is used to house pasteurisation tunnels for the production of mushroom compost.

Built by Ashridge Construction Ltd, HCS Cladding & Construction Ltd, based in Lincolnshire was in charge of installing the Cemsix for Tunnel Tech. “We needed a new roof that kept the profile as low as possible to keep the building’s height low for our neighbours.” explains Tim Harker Director & General Manager of Tunnel Tech Ltd “We also needed a material that could match the clients colour and material specification. Cembrit’s Cemsix was a perfect match for us because of the available colours and its durability, not to mention the good delivery service Cembrit provide. We are impressed with the high quality finish that blends an immense building into the natural landscape.”

Pete Hockin Contracts Director at HCS Cladding was also impressed with the service Cembrit provided; “‘Cembrit provided an excellent service prior to any orders and delivered as per our programme once orders had been placed. We have used Cembrit on other projects since and are completely satisfied with them as one of our suppliers”

Fibre cement has the advantage of being slightly porous. This means that high levels of water vapour or humidity within agricultural buildings can be absorbed by the sheets and gradually released to the atmosphere, rather than condensing on the under side of the roof and dropping back onto the crop. In effect the Cemsix sheets are helping create passive environmental control for the buildings interiors.

Cemsix sheets are ideal for agricultural, commercial and industrial buildings, robust and practical requiring no maintenance to preserve its strength. The durable and weatherproof sheets are not affected by destructive fungi, vermin or insects, so will not rot or decay; and are available in natural grey, matt black and ten attractive pre-coloured options. Offered in a standard imperial 6 inch profile it is strengthened with strategically placed polypropylene reinforcement strips. These are incorporated within the fibre-cement sheet to comply with BS and H&S requirements for site safety and fragility. 

Cemsix also conforms to the necessary fire safety requirements being a Class 0 surfaced material with an EXT.S.AA rating. Available in a variety of sheet lengths, the Cemsix range also offers a wide range of corrugated sheet accessories including ventilation to satisfy any roof design. Cemsix has full BBA certification: 03/4049 and a warranty is available on request.
