HOW TO - Beat the cold by installing Siniat Thermal Boards

welcome to seniors introduction to thermal boards we're all experiencing large energy costs in gas and electricity we can help reduce these costs by using the thermal boards we all lose heat through our walls through our windows and especially in the loft area the UK government to take in steps to improve the thermal efficiency of new and existing buildings in England and Wales through Part L of the building regulations Northern Ireland is the technical standards F one Scotland technical handbook domestic Section six the government regulations are stated as you boughs so what is it you value it's a measure of heat loss through parts of the building your walls your roofs no individual element has a you value but it will form part of it all elements of the wall construction form part of the you value calculation our technical service team can calculate your current new value of your wall construction but there's information that they'll need is a property rendered is it rendered onto brick or block does it have a cavity is the cavity insulated internal wall is it brick is it block and is it plastered given that information they can actually calculate your current new value we can then calculate from the range of boards and thicknesses which one you should use to meet your required you value Cynthia has four Thermal boards in its range these varying thickness but are all laminated to a 1200 by 2 400 plus the board we first of all have the basic EPS this is basic polystyrene laminated to a plus the board we then have XP this is extruded polystyrene moving up we then have firm or PIR now this is actually laminated to a vapor barrier as well and is a much higher grade foam and finally we have thermal K this is phenolic phloem and like the PIR also has a vapor barrier what is a vapor barrier a vapor barrier is a metallized foil laminated to the back of a plaster board the insulation is then laminated to this it reduces the risk of condensation occurring in the cavity both PIR and thermal K have this so we would use it loft conversions seller's solid walls and even garage conversions I'm now going to take you through the methods of installing thermal boards there are three this independent wall liner as the name suggests it stands completely independent of the existing background examples of this are stone walls in barn conversions we then have the dry liner system this can be used on solid walls because it's a solid wall there is no cavity so we need to create a cavity but the walls are fairly true and finally we have direct bond which is actually sticking the plaster boards to the wall using the Sania Universal bonding compound I'm now going to demonstrate how we fix a thermal board using the direct bond method it varies from fixing a standard wall board there are a few differences one of them being we have to use an ailable plug this is a secondary fixing required for fire safety reasons bucket trowel or you can use a gauging trowel you'll see me abusing both tape measure so you can cut your plaster boards to length hammer but knocking home our navel plugs and a saw because unfortunately using thermal boards it's not a cut and snap we will have to saw the boards to length and finally a drill cordless or otherwise this will be used to drill our holes for our nailing ball plugs and one final thing a straightedge this will be used to get the board level and true now for the demonstration of installing a thermal board what you will need to know is it's actually the Hamm board that puts it on the trowel and not vice-versa for those of you have not done it before so if you have attempted a bit of plastering or attempt to direct bond before I've probably finished up with most of it on the floor what you try to do is that in actual fact if you give the the whole color hand board a little shake it won't come off you can then take your trowel across the surface as you get to the edge press on and take it off we haven't dropped any and that dab is the correct size it's between 230 250 millimeters in length and it's between 50 and 75 millimeters in width we can now apply this to the wall you'll notice there is a difference between fixing standard wall boards and thermal boards you need four rows of dabs and because it's on an external wall or the perimeter of the wall will be completely sealed and also any window or Doran is around those again you will completely seal them with the Dubs now install you can see I have a continuous ribbon at the ceiling wall angle the internal corner and the skirting line it's also important that the dab centers are 300 millimeters apart not 300 between the dabs we've got sufficient dabs we're now ready to place the board in position so with our board cut to size I placed a couple of Packers on the floor the reason for that is remember no plus the board should ever be in contact with the ground in case any water is spilt or there's a leakage anything like that gypsum lose water place the board on the Packers and nice and tight into our internal corner just resting the board against the dabs we can now use our straightedge to level the ball aha see I have here which means at the top and a little bit at the bottom need to go back across to the corner and you can see the bottom really needs to go back do the vertical check the center of the board and then finally check going across narrow for the next board Silver's top tip the nail above plugs are better done the following day that way you can guarantee that your bonding compound has had time to set and dry the reason for that is when you're fixing these you will need to drill into the board and you'll also need to knock them in to place it using the hammer and doing that while the bonding compound is still wet it's going to distort the board so now the following day we could see that our bonding compound is set so we're ready to install our notable plugs what length do I need the rule of thumb is 50 millimeters plus your board thickness that means the maximum dub thickness you can have arrived is 25 millimeters and you need a minimum of 25 millimeters into the masonry background hence where the 50 comes from plus the board tells you what length you require if your measurement actually falls in between the lengths available you always go to the next size up never down they go 300 millimeters down from the ceiling and 25 millimeters in from the board edge so you can measure 300 millimeters down from the ceiling I'm 25 millimeters in from the board edge these two pair board so you will need to do that on both sides I'm now ready to drill and put my plugs in place with the holes drilled and now placing the plugs with our boards now install you can refer back to our video
