Tinted in 480 Atlas SAH shades on a dedicated Atlas mixing machine at our Southampton warehouse, Atlas Silicone-Silicate Render combines an organic siloxane resin with an inorganic silicate binder for V1 vapour permeability at Sd below 0.14 m — the highest breathability class in the range — covering approximately 10 m² per 25 kg tub, certified to EN 15824:2009 under DoP 125/CPR across three Atlas ETICS approvals (ETA 06/0081, ETA 06/0173, AT-15-9090/2014). Where Atlas Silicone-Silicate Render Performs Best — Heritage and Breathable UK Walls Listed buildings, conservation-area properties, pre-1919 solid-wall homes, AAC-block construction, and any substrate that depends on outward evaporation to manage moisture demand a thin-coat finish that breathes as freely as the wall behind it — Atlas Silicone-Silicate Render is the hybrid dual-binder formulation built for that brief, certified V1 with Sd below 0.14 m to EN 15824:2009 (DoP 125/CPR), with A2-s1,d0 reaction to fire and ≥ 0.35 MPa adhesion. Part of the premium silicone render range, this 25 kg ready-mixed render covers approximately 10 m² at 1.5 mm grain (2.5 kg/m²) or 7.8 m² at 2.0 mm grain (3.2 kg/m²), with the spotted (baranek) texture available across the full 480-shade Atlas SAH palette and bespoke RAL or NCS matching mixed on the same Southampton equipment. The chemistry sets this render apart from every other thin-coat in the Renders World range. An organic siloxane resin delivers hydrophobic surface behaviour and crack-resistant flexibility, while an inorganic silicate binder forms a true chemical bond with mineral substrates — natural stone, lime plaster, brick, AAC blockwork — rather than relying solely on a polymer film. Dispersed microfibres reinforce the render through its full thickness, absorbing thermal expansion, settlement shifts, and minor impact stress so the surface flexes with the building rather than developing hairline cracks over a long service life.
