White aluminium roof lantern interior view

More sky, less roof

Our roof lanterns might utilise a minimal design made possible with slimline technology, but this doesn’t mean that they ever open your conservatory to risk of draughts and cold spots. Comprised of energy efficient glazing and rafters, each lantern delivers impressively low U-values of just 1.5 W/m²K – that’s twice as efficient as the nearest competitor. The space will remain comfortable all year round and the risk of condensation is reduced.

Roof lantern efficiency

Roof lanterns from Double Glazing Essex Ltd are a thinner, stronger, and lighter design than most, maximising the amount of light capable of entering. This will give your conservatory a more natural feel that’s in-keeping with how much closer you are to your garden, also leading you to rely less on artificial lighting. With roof lanterns, less is definitely more!
