Reflection Absorption Insulation

Ultrasol Window Skins: solar filtering thermal insulation.

A patented process of an aluminium-coated, infused PET sheet, perforated and laminated to a sheet of clear PET. Engineered by Ensol to work in two modes, all year round, on the weakest thermal element in any building, glass.

What it is

The thermal hole in every building.

Space heating and cooling account for 40–65% of energy costs in many buildings, and most of that energy escapes via glazing. Ultrasol works as a radiant barrier installed inside your existing window, addressing every mode of heat transfer through glass in a single application.

Heat Transfer · Where it enters

Windows are the weak point

Windows account for 72% of unwanted heat gain, far outweighing roof, walls, infiltration and floors. Fix the glass and you fix the building.

01
Reflectivity

High-reflectivity aluminium reflects solar heat and UV back outward.

82%Solar Rejected
02
Emissivity

Low aluminium emissivity (0.03–0.05) means only 3–5% of unwanted heat is re-emitted into the room.

03
Absorption

A UV-filtering polymer layer absorbs harmful ultraviolet light that damages occupants and finishes.

How it works

Protection and Insulation, all year round

Ultrasol is reversible: silver side out in summer rejects solar heat; black side out in winter absorbs solar heat and re-radiates it back into the room.

Summer · Silver side out

Solar Rejection Mode

Solar heat and UV rays reflected outward. Cool interior air insulated from hot glass. Daylight passes through with reduced glare.

Winter mode diagram: solar heat absorbed and re-radiated into the room, warm air insulated from cold glass, UV rays reflected
Winter · Black side out

Solar Absorption Mode

Solar heat absorbed and re-radiated back into the room. Warm interior air insulated from cold glass. UV rays still reflected.

Construction

Micro-thin engineered layers.

Ultrasol is built from micro-thin layers of dielectric coatings on highly reflective aluminium, bonded to a perforated carbon-graphite PVC sheet and laminated to a clear UV-filtering polyester, a stack engineered for reflectivity, strength and UV absorption.

01
Dielectric-coated embossed aluminium

High reflectivity & very low emissivity (0.03–0.05).

02
Carbon-graphite PVC

Strong, light, heat-resistant, perforated and embossed for structure.

03
UV-filtering polyester

Clear outer polymer that absorbs harmful ultraviolet light.
