Maincor Overboard has been designed for tasks together with extensions, kitchen refurbishments, or upgrading home heating techniques.  

Overboard dry screed panels are used as carriers for pipes in underfloor heating techniques. The bodily properties of the panels enable warmth to unfold successfully, which signifies that set up of warmth emission plates is just not required.  

Panels can be found in two configurations, as straights and as finish returns. Nearly all of the heated ground space will normally be lined by the straight panels that are 1.2 x 0.6m and 18mm excessive. The top returns are used the place feed pipes are laid. These are 0.6 x 0.6m (precisely half the dimensions of the straight runs), minimising chopping.

STEP-BY-STEP*

1. Earlier than you begin to set up the Overboard system, the working space must be ready. For those who take time to plan your set up previous to laying, it can minimise the necessity to minimize panels. 

The world should be climate tight. Be sure that the panels, manifolds and electrical elements, are sufficiently protected.   

The ground must be strong, degree, clear and freed from particles. A levelling compound can be utilized to arrange the ground the place it’s uneven. Screw down any uneven floorboards or substitute as required.  The sub-floor ought to adjust to the necessities of the Constructing Rules Accepted Doc L. 

2. The Overboard panels must be picked up centrally to keep away from breaking the corners. Care must be taken and consideration given to the load of the panels when lifting. 

3. The place panels must be minimize, a handsaw, round noticed or jigsaw must be used to make sure they match the contours of the wall. An appropriate mud extraction system must be fitted when energy instruments are used. Alternatively, the panels might be scored and snapped with a pointy knife and straight edge. 

4. Set up Maincor edge insulation across the perimeter of the room if wanted. The panels should be laid onto a strong, agency sub-floor. Overboard panels must be put in constantly (there’s no want to put in brick formation), making certain the pipe channels are lined-up to take the pipe. 

5. Previous to laying the pipe, the runs must be decided and energy made to minimise the connecting lengths from the manifold to the pipe channels. The runs must be marked on the panels previous to routing and the pipes mustn’t cross one another throughout the ground. 

6. The panels must be fastened on to the ground utilizing the Mainadhesive or Overboard screws supplied. Usually, screws will likely be used for fixing to timber sub-floors and adhesive or screws and rawl plugs for concrete flooring. If utilizing screws, pilot holes and countersinking is just not vital and the screw will maintain higher if screwed instantly into the panels. Repair across the perimeter of the panels at 200mm centres (not contained in the channels). 

If utilizing Mainadhesive, it can increase and absolutely set in roughly 4 hours – care must be taken throughout this time to keep away from extreme visitors. It is suggested that dots of adhesive are utilized at 200mm centres across the perimeter and throughout the subject of the board. After the adhesive has absolutely set, any extra might be scraped off utilizing a filling knife. 

7. As soon as the panels are laid, the Mainadhesive has set and the feed channels have been routed into the panels (if required), the pipe is able to be laid. To keep away from an extreme stress drop and keep the utmost system output, every coil of pipe mustn’t exceed 80m in size. The pipe must be held loosely and walked into the panels.  

Take care to make sure the pipe is just not kinked, but when this does occur, reform the pipe and create a extra gradual bend. The pipe suits very snugly into the pre routed channels and when inserting, there are three fixing factors in every channel. 

8. As soon as stress testing and commissioning of the system are full, set up a separating layer. This may rely upon the kind of ultimate ground end and additional recommendation on this may be discovered within the Overboard brochure on the Maincor web site. The joints must be staggered relative to the panels beneath and stuck down into the Overboard panels with appropriate screws. 

9. Maincor’s Unitop4 board is a warmth distributing 4mm thick, decoupling/stress relieving layer which additionally reduces affect noise and is appropriate for visitors a great deal of as much as 5kN/m².  

The compressed cellulose board must be laid upon a mattress of MS Adhesive. There’s a 25% enhance in warmth output when utilizing Unitop4 in contrast with ply.
