Argon filled units are the ultimate in glass-insulated units. Argon combined with Pilkington "K" or Low E glass is just about as good
as it gets in terms of insulation. We are now talking as good as or better than most brick built extensions in terms of insulation.
Not particularly expensive (only £10 -£15 per sealed unit in the UK) and well worth the extra expense. Please note that Argon filled
units combined with "K" or Low E glass will give the best results. On its own the benefits are only marginal.
