With the new design of VISTA built-in fireplaces, we have taken a different approach combining craftsmanship and quality with a “sleek” design. Although the focus is on the spectacle of the flames, the device itself makes use of today’s most refined combustion techniques. This cozy insert transforms any existing open fireplace into an environmentally friendly closed fireplace. You have the choice between slat-shaped cast iron or vermiculite stones for the interior lining. In terms of finishing touch, you can choose for “minimalistic”, using the 4 mm. “slim-trim” around the fireplace or add the additional wider frame of 25 mm., which is delivered with the unit. This version specically is with a cast iron interior and comes as an “insert”.
