Exclusive to Room Outside

What is New Generation Glass?

In 1999, we were the first company to exclusively introduce groundbreaking solar-controlled glass to the UK.

It reflects heat and light back to its source, maintaining the perfect temperature in your glass room throughout the seasons.

NGG offers unparalleled solar control and outstanding thermal performance, making it the best product in its class. Additionally, its self-cleaning technology ensures minimal maintenance, meeting the unique demands of a room built entirely of glass.

Why Choose New Generation Glass?

Advanced solar control and thermal insulation for year-round comfort.

Solar Control

Reflects up to 86% of the sun’s heat in summer, keeping interiors cool without excessive air conditioning.

Thermal Insulation

U-value under 1.0 W/m²K retains warmth in winter, reducing heating bills and eliminating cold spots.

UV Protection

Blocks virtually all harmful UV rays, protecting furnishings, flooring and artwork from fading.

Self-Cleaning

Optional polymeric treatment creates a non-stick surface – rain washes away dirt, reducing maintenance.

How It Works

Every pane combines warm-edge spacing, Low-E coatings and gas filling for ultimate performance.

Warm Edge Technology

Our spacer bar is up to 950 times less conductive than aluminium, increasing internal edge temperatures and significantly enhancing insulation. This eliminates condensation and cold spots around the perimeter.

Low‑E Coating

A microscopically thin metal oxide coating reflects heat back to its source. In winter, it keeps warmth inside; in summer, it reflects solar heat away – all while letting light pass through.

Argon Gas Fill

The sealed cavity is filled with argon gas, which is denser than air and provides superior thermal insulation. This contributes to the exceptional U-value of under 1.0 W/m²K.

See the Difference for Yourself

Watch our heat tunnel demonstration comparing New Generation Glass with standard conservatory glass. The video shows how NGG dramatically reduces heat transmission, keeping your space comfortable even on the hottest days.

Heat reflection: The left side of the tunnel (standard glass) allows significant heat through, while the right side (NGG) remains cool to the touch – a visible demonstration of 86% solar reflection.

This isn’t a simulation – it’s real proof of the technology that makes New Generation Glass the most advanced choice for your extension.

New Generation Glass FAQs
