IKO Undertile Felt is the traditional underslating, complying to British Standards and still favoured by many roofers.

IKO Undertile Felt Reinforced slaters' felts are manufactured specifically for use as an underslating beneath tiles or slates in open rafter construction. It can also be used as a vapour retarder in built-up roofing. IKO Undertile Felt has a felt fibre base combined with a layer of open weave hessian, saturated and coated with bitumen and surfaced with sand.

Although designed to be an extra safeguard against water penetration when tiles or slates become dislodged or damaged and against wind driven rain or drifting snow, this product also plays a major part in preventing wind uplift of the tiles or slates
