Roof tile people Sandtoft’s 20/20 interlocking clay plain tile can be used at roof pitches as low as 15 degrees.
The lower pitch performance means the 20/20 can be used particularly effectively on extensions, which are often built at a lower pitch than the main roof because of the position of the side windows. As guidance from the British Standard recommends that traditional plain tiles should be used at a minimum pitch of 35 degrees, matching an extension to the main roof can be difficult. The 20/20 solves this problem, meaning that an aesthetic roof can blend into the rest of the property.
Nick Oldridge, sales and marketing director at Sandtoft, said: “We established the lower pitch during six months of wind tunnel tests.”
Made using precision plaster moulds and alluvial Humber clay, the 20/20 features high definition interlocks, together with weather bars and a protected nail hole, making it resistant to wind driven rain and snow.
