  • Patent number: 9206602
    Abstract: The present invention provides a loft flooring system that comprises: a plurality of bridging supports each adapted to bridge between an adjacent substantially parallel pair of joists of a loft floor and having a first upright leg with a foot to mount onto a first of the joists and a second upright leg with a foot to mount onto a second of the joists, and a spanning element therebetween onto which flooring boards/panels may be laid. The insulation can be laid between the joists to a required depth rising above the joists and the bridging support mounted in place accommodating the laid insulation thereunder so that the insulation remains substantially un-compacted and fully effective.

  • Publication number: 20150337531
    Abstract: The present invention provides a loft flooring system that, inter alia, comprises: a plurality of bridging supports each adapted to bridge between a substantially parallel pair of joists of a loft floor and having a first upright leg with a foot to mount onto a first of the joists and having, in use, a second upright leg with a foot to mount onto a second of the joists, and a spanning element therebetween defining a flooring surface or onto which flooring boards or flooring panels are laid, wherein each leg is initially separate and the spanning element is an initially separate beam that is mounted to the legs to span between the joists. The system is comparatively straightforward and efficient to install and, where needed, uninstall and also is robust and stable. With special support arms on the legs or hung from the spanning element it can also greatly facilitate discrete management of pipe-work and cabling below the raised floor too.
