How To Install Korniche Bi-folding Doors

[@glazingstore1178]

This is our Favorite Product we have on offer at present we Sold the first online Korniche Bi-fold door last year and sold more of these than any other throughout December! Another great install By Roger the Skill Builder thank-you for covering this door in one of your projects we strongly believe these will be the best selling Bi-fold of 2022!

[@Serifs67]

[@robpaige4953]

Hi Roger, great video, have watched your Korniche lantern video and will be installing 3 of those in the next month or so but just wanted to ask about how the cavity had been finished below the threshold, as there appears to be a number of ways of doing that and what type of fixings you were using to fit the head of the frame to the steel lintel, thanks

[@smallcarpentry]

Fitted some today and no instructions with it. The leading door is so out hopefully when I glaze it tomorrow it'll be ok. Great video again, been a Chippy for 12years now and still love watching all the videos :)

[@JohnW220Turbo]

Nice video. Bit of a trade tip for those who are fitting without a laser level... get the jambs and threshold level, cut a piece of cls or tile lat to the internal opening rebate size, then slide along the width of the frame to level the head.

Excellent product. (So good I wish I had a reason to buy it. But I don’t. Also, wrong country.). Excellent tutorial. Full of insights that are applicable to any door and frame installation. And RTFM (substitute “manual” for “instructions”) always good advice.

[@MatSmithLondon]

Oh Roger. I watched this and my heart sank. The bit where you talked about membrane under the doors. We had a set of expensive sliding doors installed - costing a five figure sum of money - and they didn’t lap the membrane up that step. We have water ingress. It goes under our screed and finds its way to a hole in the suspended slab and drips into ceiling of basement below. Since doors went in, we had a very good brickie build us some beautiful reclaimed stock brick pier skins on the outside. Gorgeous pointing, best I’ve seen so far. We chose every brick by hand, rummaging through old piles at merchants. The doors are fixed to the INSIDE of the inner block skin, fixed inside the cavity. So we can’t just lift and retrofit a membrane. We discussed this at the time but ploughed on anyway. Thankfully no kitchen or floor finishes yet. I’m wondering if we can resolve this by somehow bonding to the TINY bit of concrete subfloor between screed and door frame then pouring in some kind of waterproof latex. Either that or the whole damned lot is coming out. Am so gutted. We are royally screwed. Sometimes wish we could just have you here for the rest of our build 😥😥😥

[@MMG_MoonManGuitar]

Why did they fit to the inner block rather than outer???

[@MatSmithLondon]

@@MMG_MoonManGuitar outer wasn’t built yet, they wanted to fit the frame from outside before we built outer skin…

[@MMG_MoonManGuitar]

@@MatSmithLondon fair enough mate. Hopefully you can get it fixed.

[@SteS]

A 2 part epoxy DPM might work if you can get good coverage under the door frame if there's space underneath it.

[@slw0599]

Wow! It only takes 19 minutes? Right I'm gonna get some! 😂

[@blowduke]

I use pumps to square up and a batten cut to the height to check along the length of the door if you haven’t got a laser level ..

[@SteveRogers461]

Our cowboy fitters didn't know about heel and toe and after a couple of open and closes, the doors feel out of the track. I managed to catch them and phone for help but they were insanely heavy. We don't really use the doors much now because it would cost hundreds to get them sorted.

[@tomclarkson6078]

Always gets me how they put so much effort into aluminium with thermal breaks yet they are happy for fitters to sink fixings straight through it. Yes this is dependent on the system you use e.g Sapa, technal or in this case korniche but when you work with schuco products it does make you think.

[@GG-ch1hm]

People fix through the thermal break due to laziness and ease of drilling through the plastic

[@SkillBuilder]

It is exactly where you should fix it.

[@booboo-nl3wi]

No it’s not, the plastic can split and crack in cold and hot temperatures it’s the absolute last place you should fix it , you need to take the gasket out and fix behind

[@fireblaster9961]

To be fair if it’s going arrive assembled you may as well get the fitters to install it.....if there’s one tip for any window/door install is to get it in there square because glass only comes square

[@SkillBuilder]

Fire Blaster I wish you were right but the thing about a lot of window/door fitters is that they throw the thing in and let you sort it out. We get lots of emails from people with dropped doors, water ingress and countless other problems, It was a day's work to fit the doors and they work like a dream. I have spent a lot longer putting other fitters jobs right. Look at the comment from Mat Smith above.

Hi Jeff, I have never understood why window manufacturers put a hole in their windows. My girlfriend’s house has these holes, the wind howls through that hole, and although it is at the top of the window, you can feel the draft from six feet away. I made some covers to go over the holes and this has made a massive difference in all the rooms. As they are fitted to the windows you are installing I though you would be the best person to ask what they are supposed to do.

[@SkillBuilder]

It was the Building Regs. Nobody likes putting them in but.... you got to get it all signed off.

That pencil line on the 4x2 is plenty thick enough, a sharper line makes reading the laser slightly easier. Especially if you’re teaching newbies. How are you waterproofing the inside of the pillars? Roger

There is a good soffit on the roof so the piers will not get wet. The pencil line is fine because I take the middle of it.

[@chrishollingsworth1980]

Hi roger:just a quick question my new kornich bifold door arrives in 7 days time could you advise on fixings into a medium density breeze block wall,as I’m a bit worried about using concrete wall fixing screws thanks

[@SkillBuilder]

Hi Chris There is no pull out force to talk of so you are looking at sideways force. Concrete screws are best because they don't have an expansion force which can tend blow the edge of the block out. I think by the time you get the foam in there, it starts to firm up but I also like to get a few head fixings in because that is what counters the weight of the doors when they are open. If you are concerned but some metal plates or straps on the side of the frame and run them back to the inner skin. I like to do that if there is not much meat in the external skin.

[@ashleyberry1116]

Have I missed something? You say take off 10mm so there’s 5mm gap all the way around but on that bottom frame you’ve got about 15/20mm of packers? Where has all that gap come from?

[@jasonantigua6825]

Toe&heel is a phrase that racing drivers use! Richard is it never good to have a damp patch in any situation? Thanks

[@grahamsmith8122]

I'm having some Express Bifold sliding doors fitted next week. they are to be flush with the floor and sit in a trench. What do you put under the lower track once its fitted and sitting on packers? I would prefer it to sit on self leveling compound that is exactly horizontal so it spreads the load evenly? Packers seem to be a bodge from an engineering prospective? What do you think?

[@SkillBuilder]

I always put a level bed in and then a piece of damp proof course that goes under the cill and up the back to the floor level. If packers are use the space in between is dry packed with sharp sand and cement so it gives even support. I would then remove the packers and fill the gaps with more dry pack. I only ever view packers as a way of getting the door level.

[@E69apeTheMatrix420]

Meant to use frame sealent in the screw holes before you put screws in or at least a blob on top of the bare screw (colour matched.) Every screw needs a packer and would have been good to see you seal it all up. Everything else was a good install though. Nice job on your own.

[@SkillBuilder]

I usually do put a bit of grey silicone on the heads but only after I have dry packed. Then I find the sealant has somewhere to go and doesn't just appear underneath. That said the frames are made to drain so the water will get out.

[@E69apeTheMatrix420]

@@SkillBuilder Nice, thats good. I plan to use expanding foam before the sealent round edges with the gun turned down very low. Did you do that? I have 8 windows and 3 doors on the way. I'm nervous because it's currently a 1 man job but I'll get it done. I noticed the in-designed weep holes that's a decent unit along with the special seal. Mine are all off the shelf B&Q (Crystal) and Wickes (Euramax) No idea what to expect but they were nice and cheap with added 10% discount that's for sure. About 1/4 the cost of made to measure and with the luxury of taking back for whatever reason if needs be. 🤞

Trickle vent, a vent to reduce condensation. I know this because when I moved into my flat there was so much water dripping off the ceiling I thought there was a leaking pipe but it was just condensation: cured with an old fashioned air brick.

[@valtherkjaer7129]

Hi Roger What is the golden rule for the door threshold is higher than the outdoor floor - suppose indoor and out door - finished floor will have same hight

[@SkillBuilder]

You need that jump up on the dpc. The frame can sit flush and the inner and outer floor levels can be the same but the bottom of the frame is sunk below that level and a bit of dpc comes up the back to the floor level. You need the frame to drain to the outside.
