Hi I just want one that is insulated and air tight do not need a laser as no need to access the space unless need to inspect the roof for some reason. Also do not think there is the space to put in a ladder. Also the sizes are odd so one would definitely not take a ladder. So I just need to understand what the Scottish regs are then I can spec the hatch.

Hi I am looking for 2 loft hatches and struggling to find out what the Scottish regs are for them as can not get in touch with building inspector. Can anyone advise I can find the English regs online but not sure if Scottish ones are different. Also where is the best place to buy them from as I may need custom sizes as I have one opening 555 wide and the other 390mm wide but the lonth can be standard thanks

Hi Just interpreting you notes So I get hydrochloric acid 16% the one @Temp gave a link to. Spray it on wait until the fizzing stops - spray on again wait until fizzing stops this process should not take more than 2 minutes then presure washer off Is that correct not sure why you note has 2 references to hydrochloric acid at the top thanks

Hi Can anyone advise what is the best way to remove efflorescence from block work before I put stone cladding on and get the house rendered? It is very thick and there is a lot of it what is the best thing to clean it off with have tried vingar with liitle effect except it started to make a fizling noise

could it be just painted render board

Hi Can anyone advise what you think they have used for the window reveal in the attached photo thanks

following this I have just had my render company out for a quote He has said to use either JUB Nanofinish Thin-Coat Render or Weber Monochouche. I was leaning towards the JUB as I live in an exposed area next to trees and thought it would be easier to clean ect and with stand the elements more lot of driving heavy rain. Any advise or thoughts would be great

I think I will do this detail and fill the cavity with gravel then there will be plenty of air flow and somewhere for the water to drop to

I suposose I could cover the kit with 200 mm of grey plastic and fill the cavtiy with gravel

The ground level wil be raised so we have a patio and doors are low threshold onto the patio.

Not sure I understand ground level will be top of block and do not want to see top of block

Hi Starting to think about the wood clading for the house. As the clading will stop about 150mm above ground level i need somthing to hide the tiber frame and to finish it off. Can anyone sudjest what I can use. I have attached a photo and a drawing to try and demonstrate what I am trying to achive or something similare in a grey / black colour

seems to be more than the lighting causing the issue. Would it be possible to spray in somthing to fill the cavity like cavity wall insulation and keep it away from the lights?

Got this responce from Velux To provide you with some more context regarding the issue being experienced. The vertical windows are classed as class 3 for air permeability, this means that they can allow up-to 3x as more air through them as their sloping counterparts which are class 4. However we are aware of the issue, and are currently working with our production team to provide a solution on how to improve the air tightness of the windows. I understand this is not ideal at the moment, however once we have a solution we can then arrange a service call to have our technician attend your property.

I think I may of found the couplprit to the issue there is a soil vent pip going outside that is not sealed. Going to put a collar on it from the outside to see if that stops the draft coming into the service cavity. As it is in a fake wall then goes into the loft throght the service cavity. Will also go round everywhere and seal up have also been silconing the skirting boards at the bottom to make sure there is no draft coming throgh them

Yes there is so many mistakes on this build as I was not present alot of the time due to working away. My main concern is that I keep goining and i fail my air tighness test and have to rip the house apart to fix that. If that happened then I would need to give up Also Velux emailed me yestarday stating they have an issue with thier windows where they are not air tight and working on a solution to try and fix them

Hi Here is a drawing also to note that the ait barrier went in after the internel walls so it is not continuous and there is no air barier in the floor / joist zone.

Will do a sketch tomorrow of make up but the majority of the insilulation I can access due to it being a story and three quarters

It is a new build and we only have the issue on the north west side when it is extremely windy. I thought the wool and foaming where i see gaps would increase the ACH. As it is not possible to fix the barrier as it would cost to much

I have tried taping and filling all the holes but it must be burst in other places that I can not find. Also the joiners nailed through it when creating the service void. So it will be an imposible task without ripping all the plasterboard off and taking out internal walls which is not going to happen. So I need to do the best I can with what I have.

Hi Electritian has put all the cables in the loft and drilled through the pir insulation and burst the air barrier. Have pur my hand in the ceiling service cavity and air is extremely blowing through it. Tried sealing up all the holes and filling but still an issue. Very windy outside. I was thinking about putting 200mm of wool in the loft over the PIR will this stop the drafts coming from the loft?

No, Still not fixed. Our house is in a valley and when the wind is above 20Mph the seals do not hold on the Velux windows and the wind howels in Going to email Velux today.

No they did not fit it. The installers that did it I am not in touch with anymore so will get another company to do it

got a reply from Express and they have sted it is either the jams (these look ok) that need adjusting or the door toed and healed to correct the issue

I have contacted Express bifold who I bought them from to see what they say but they after sales is poor.
