What's the difference between soft coat and hard coat Low-E glass?

Soft coat Low-E offers superior thermal performance with U-values around 1.0 W/m²K but requires sealed unit protection. Hard coat is more durable but achieves slightly higher U-values of approximately 1.4 W/m²K.

What U-values can Low-E coated glass achieve?

Our Low-E sealed units achieve U-values from 1.0-1.6 W/m²K depending on coating type, gas fill and spacer bar specification. Argon-filled units with warm edge spacers deliver the best thermal performance.

Can Low-E coating be applied to any glass thickness?

Low-E coatings work effectively on glass from 4mm to 10mm thickness. We typically recommend 4mm Low-E glass in residential double glazed units and 6mm for enhanced durability in commercial applications.

How do I order made to measure Low-E glass units?

Simply provide your exact measurements in millimetres along with frame rebate details. We manufacture to ±1mm tolerance and typically deliver within 5-7 working days across the UK.

Energy-efficient coatingsSoft coat & hard coat options

Low-E (low emissivity) coatings are the technology behind modern energy efficient glazing — a microscopically thin metallic layer that reflects heat back into your room. Our Low-E units keep your home warmer in winter without reducing the natural light coming through.

About Low-E Coated Glass

Low-E coated glass features microscopically thin metallic coatings that reflect infrared energy back into your room whilst allowing visible light to pass through. Available in soft coat and hard coat variants, our sealed units incorporate this advanced coating technology in configurations from 4mm to 10mm glass thicknesses.

Our Low-E sealed units achieve U-values as low as 1.0 W/m²K when combined with argon gas fills and warm edge spacer bars. All units meet BS EN 1279 standards and deliver exceptional thermal performance, reducing heat loss by up to 30% compared to standard double glazing whilst maintaining excellent light transmission.

Every Low-E coated glass unit is made to measure at our UK facility with precise tolerances of ±1mm. We guarantee manufacturing quality and provide nationwide delivery, ensuring your energy efficient glazing solution arrives ready for installation.
