The Benefits of Insulated Glass Units

SafeGuard’s IGUs are built for performance, longevity, and clarity

  • Exceptional energy efficiency – Low-E coatings and argon or krypton-filled cavities help reduce heat loss and energy bills.
  • Noise reduction – Multi-layered glass with acoustic options ensures a quieter, more peaceful environment.
  • Condensation control – Warm-edge spacer technology minimises cold bridging.
  • Durable & long-lasting – All units are fully sealed, moisture-resistant, and tested for reliability.
  • Bespoke production – Made to measure for any frame type, shape, or application.
  • Sustainable choice – Improved energy performance supports lower carbon emissions and a greener future.
  • Outstanding solar control – High performance coatings eliminate excessive heat build-up whilst allowing sunlight into the room.

Design & Performance

Modern Performance, Timeless Window Design

Every Insulated Glass Unit is assembled using precision-cut glass panes separated by a thermally efficient spacer bar, sealed to create an airtight cavity filled with argon gas for superior insulation.

We use low-emissivity coatings, warm-edge spacers, and dual-seal technology to deliver consistent performance and long service life.

Whether you need slimline double glazing for heritage frames or high-spec triple glazing for modern builds, SafeGuard can manufacture a unit to suit your exact requirements.


Our sealed units achieve BSEN 1279 parts 2 & 3 along with British Standard Institute (BSI) Kitemark first awarded in 2005 and have since consistently passed regular audits. Sealed unit guarantees up to 10 years depending on type of frame.
