Weight: Made from heavy timber, insulation materials and tiles, Clad over solutions are often too heavy for existing frames. Old conservatories need a lightweight roof and the lightest solid roofs come in at 31KG/M ².
Our Tip: Always speak to your installer about the total unit weight of the new roof per Sq.M
Fire Safety: Clad over systems are only tested for fire safety as individual parts and never as a complete roof structure. It is necessary to be tested as a whole structure in order to meet fire safety building regulations. Solid roofs must be classified as AC, AB or AA in accordance with BS476-3.
Our Tip: Request to see the fire safety certificate of the entire roof system before moving forward.
Building Regulations: Clad over systems often don’t get Building Regulation Approval because of their low thermal value or structural integrity. You should not confuse this with the commonly necessary planning permission. You must notify Building Control if you are making alterations to any structure (including replacing a glass or polycarbonate conservatory roof with a solid roof). Their approval ensures your new roof is structurally sound.
Our Tip: You should ensure that local Building Control has been informed before the conversion begins. Remember to obtain a Building Regulations ‘Final’ Certificate and file it in a safe place.
