Available as inward opening tilt & turn or outward opening fully reversible windows, these timber windows use engineered oak frames and have been tested to achieve fire resistance standard EI45, meaning they prevent the passage of flames, fume, toxic gases, radiant heat, and temperature completely for a period of 45 minutes. Suitable for use in any buildings where fire resistance is required to achieve building regulations compliance but where a timber window is preferred vs aluminium.
