The terms refer to the number of silver layers in a soft coat. Single silver soft coats are more cost-effective as they are cheaper to produce, however have lower performance. Triple silver soft coats have three layers, enhancing the IGU's ability to reflect heat and improving solar performance.

Hard coat (Pyrolytic Coatings) Low-E consists of a single layer vapor deposit applied at high temperatures during the float glass process. Hard coats are ideal for use as a single (monolithic) piece of glass as the coating is highly durable.

Soft coat (Sputter Coats) Low-E coatings are applied in a large magnetron sputter vacuum deposition (MSVD) machine. This allows for a nano-technologically precise coating with multiple layers of metals such as silver, greatly improving performance. Soft coats typically achieve greater solar control, higher visible light transmission (VLT), and lower U Values compared to hard coat Low-E glass. Soft coats can only be used with an IGU as the coating is fragile and easily damaged.

The soft coat Low E used in our InsulCool range of IGUs is sourced from a range of leading global manufacturers including Guardian, ACG, Saint Gobain, and others.

Unlike conventional aluminium spacers, warm edge spacers are made of composite materials and extruded via CNC directly to the glass during manufacure. This combination of material and manufacturing technology results in a spacer that has lower thermal conductivity, reducing heat loss and maximising thermal performance. For IGUs filled with argon gas, warm edge spacers offer vastly improved impermeability with effectively zero leakage over the lifespan of the unit.

All InsulCool IGUs are manufactured with warm edge spacers as standard.
