Structural posts are designed to be used to provide a means of supporting the roof and transferring the weight directly on to the existing base work. The post is designed to bolt directly to the ring beam and fix down on to the dwarf wall.
The specification can only be determined by the surveyor after taking into consideration the condition of the existing window frames.
The following are recommendations based on a worst case scenario however the addition of walls in the building mean the calculation will need to be done based on window frames.
For building without brick walls the following calculation should be used:
1 post for every 6m2 for shingle tiles
1 post for every 5m2 for slate tiles
1 post for every 4m2 for concrete tiles
Any elevation with a window frame manufactured in one section in excess of 2400mm in length.
Any elevation with a continuous frame length exceeding 3500mm
Celsius solid roof features a structural array of eaves timbers, wall-plate timbers, eaves fillet timbers, ridge
timbers, rafter and butt joints, in addition to hip timbers for Victorian and Georgian designs, which are square
cut or mitre cut as required to construct a purpose-built framework for the interlocking SIPs, tailored for specific project requirements.
Synseal’s Celsius solid roof system is comprised of 9 standard timber sections
Sections are machined from C24 construction grade structural timber (German white wood)
Standard timber sections are used to form both Ridge and Hip components
These are bonded with timber adhesive and mechanically fixed in the factory, then cut to length to suit each
Kingspan TEK Building System panels consist of a high performance rigid urethane insulation core, manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP), sandwiched between two layers of Oriented Strand Board type 3 (OSB/3). During manufacture, the insulation core is bonded by autohesion to the OSB/3 facings. This process provides more reliable and superior adhesion than the secondary bonding process used in the manufacture of most others SIPs.
Kingspan Insulation Ltd has secured BBA and NSAI Agrement certification for the Kingspan TEK Building System
Warmer Roof is designed to be used for new sun room installations or as a roof replacement to existing conservatories, and features a U-value of 0.14. This “warm roof” design was conceived through the use of a pod system finished off externally with lightweight tiles, of your choosing.
All structural and building regulations are met thanks to careful design and engineering. The roof has been extensively tested and certificates issued to ensure it complies and exceeds the current Building Regulation requirements for both structural and thermal performance.
GRP is used to manufacture the ring beam, rafters and ridge because it has an exceptionally high strength to weight ratio and high flexural strength.
GRP never corrodes, it is impervious to common chemicals, greases and oils, it is non-conductive, non-sparking, and non-shrinking. You may have already heard of it but by another name - fibreglass. There is no difference between them, they are one in the same, made out of glass fibres and a synthetic polymer. In the case of the GRP in the Leka system, that polymer is epoxy, which has a stronger bond than polyester.
