Rheinzink by Q&M Roofing
The brief in our Autobarn project was to reference surrounding agricultural buildings, so we specified Rheinzink in a natural finish. It quickly developed a subtle patina that complements the chestnut cladding which will silver over time. The workable nature of natural zinc allowed for a number of carefully crafted details. At the verge and eaves, the metal was folded into a minimal drip detail protecting the end grain of the vertical chestnut cladding. A recessed gutter detail also avoids the need for rainwater goods on a facade composed of moving timber screens.

Facadeshield by Proctor
We like cladding buildings using breathable timber lattice structures and open rain screen facades, which, with some weatherproofing membrane on show, need to be aesthetically discrete as well as physically robust. Proctor Facadeshield, a non-woven breathable membrane, combines water and UV resistance and allows up to 30% of the facade to be left open to the elements. Aesthetically its dark colour and lack of prominent branding allows the membrane to recede into a discrete shadow zone hidden behind the timber battens.

Troldtekt Acoustic Panel
We first used Troldtekt on our Autobarn project as an alternative interior finish to plasterboard or timber. Made from natural, sustainably sourced spruce shredded into wood wool and mixed with cement, Troldtekt has sound absorbing properties that when used on walls and ceiling create a calm, peaceful space. The rough finish and jointed boards also produced a softer, more textured interior which could have been quite stark if finished in more conventional plaster and paint. It has natural resilience and can handle moist environments, and provide effective fire protection.
