The PolyTherm Shutter Insulating System

PolyTherm® Shutters are an ideal investment for those seeking to product longevity, turn-key functionality, and stand-out aesthetics with high-style versatility to complement any interior design decor.

But, one feature that especially sets PolyTherm® Shutters apart from other plantation shutters, and any other window covering for that matter, is that they are extruded with a high density foam interior, similar to the insulation material sprayed between rafters in an attic space, thus adding another layer of window insulation.

PolyTherm® Shutters are solid core, not hollow core like other express shutters on the market.

These shutters are a game-changer for maximizing energy efficiency in any given space, lasting longer than traditional wood shutters and insulating up to 70% more efficiently.

Research carried out by The Edinburg World Heritage Trust and reported by BBC Scotland, demonstrated how keeping shutters and curtains closed at night can reduce heat loss.  Installing PolyTherm® shutters will further dramatically reduce your heat loss.
