Which Glazed Doors?


glazed doors options


The design of a single-storey rear and two-storey side extensions for an end-of-terrace house in Tower Hamlets, London is in progress. We are just before the planning submission stage, so finalising the external design.

We have made some design options for glazed doors to the rear extension as below. It could be sliding doors, bi-fold doors or some other specialist doors like slide-and-turn doors, pivot doors etc.

The appearance will be quite different depending on which system is chosen, for both closed and opened configurations. Bi-fold doors could maximise the free area when opened, but when closed there will be more visible vertical frames, while sliding doors could have wider panes with simpler and more reliable operation although the open-able area will be less than the bi-fold doors. There are always trade-offs between systems to be chosen.

We are considering specifying high-performance triple glazed unit with the U-value of 1.0 W/(m2K) or better, and this also limits the number of products which could be specified.

This time the clients decided to go for the sliding doors as the Glazed doors 03.
