How Custom Windows Improve Energy Efficiency in Modern Buildings

1. Optimised Thermal Performance

“

Bespoke windows can be designed to minimise heat loss in winter and prevent overheating in summer, reducing the need for artificial heating and cooling
.
✅ Double, Triple & Quadruple Glazing: Extra layers of glass trap heat inside, helping lower energy bills.
✅ Low-Emissivity (Low-E) Coatings: A special microscopic layer reflects heat while still allowing natural light in.
✅ Inert Gas Fills (Argon/Krypton): These gases between glass panes act as an additional insulation layer, improving efficiency.

At Sword Fixings Ltd, we offer bespoke glazing solutions tailored to your building’s needs, ensuring maximum efficiency and performance.
