The Regulations: Ring Beams

For Ring Beams

Garden Rooms using the Nicholls & Cooke RING BEAM SYSTEM would be classified as a continuous BAY WINDOW, as such when fitting by FENSA member, the technical advice issued states;

Installers are required to fit BAY POLES with header and spreader plates on all Load Bearing Bay Windows. For maximum security, safety and easy adhesion to Document A, the Bay Poles must go through the sill. The Poles must be secured to the head (or ring beam) and the wall under the sill via large spreader plates.

Nicholls & Cooke produce a range of ground anchors that transfer the weight of the roof and ring beam directly to the concrete foundations if required by a local authority. Normally our large spreader plates are secured to a suitably robust outside wall by chemical bolts (min. 150mm - 225mm recommended). Expansion bolts, such as raw bolts are not recommended.

Document A also states that NO WEIGHT or STRUCTURAL STABILITY to be taken on frames or casements.
