The ultra modern slimline Aluminium HeatGuard version is exactly the opposite.
Instead of closing off an area they give the ability to open up an area fully and even when closed offer an unhindered feeling of light and space with a picture framed view into the garden. High performance glazing and cutting edge engineering take care of the insulation, reliability and security, whilst the computer designed specification and incorporating bespoke elegant handles and hardware takes care of the aesthetics.
Almost any combination of hinged and folded leafs is possible with no limits on width. They can fill the whole wall of a room if required, truly connecting the inside to the outside 12 months of the year come rain or shine.
