Glass & Glazing

Will I get a better energy rating if I choose argon gas?

The short answer is yes you will get a better rating and the windows will be more thermally efficient.

What is the depth of your glass unit?

Our sliding sash windows hold a 24mm unit.

How is the glass toughened?

Toughened glass is manufactured by subjecting the final glass size to a heating and cooling treatment.
A balance of high compressive stresses at the surface and tensile stresses in the centre of the glass increases its strengths. It can, however, break under extreme loads or by severe impact.
