25mm between rafters?

Hardboard isn’t great, it’s basically compressed cardboard. As above, 6mm ply would be much better. staples would stay proud of hardboard more than in ply so nails are much better. Screws better still

We have loads of the 1.5m and 2m bay fairly cheap stuff in our parts rooms and they have been fantastic. Don’t go for the really cheap 900mm stuff as this is made of material thinner than meccano

Good afternoon and welcome, plenty to read while you are plot hunting.

Yes, externally this is fine - always plenty of air circulation to take the moisture away

Generally a lot of materials are back to an “acceptable” level, many suppliers were taking the p%#£ during COVID restrictions but there was little justification for it. but the runaway inflation is hitting pay rates and will cause more material rises if it isn’t deal with soon. If interests rates do not go up to a sustainable level many businesses will fail as they won’t be able to keep up with spiralling labour costs. yes the heavily in debt businesses will suffer.

During lockdown I had to pay £35 a sheet at one point

Scaffolding makes it really easy, and much less chance of damage, stainless is an unforgiving metal to work with but it is very durable and stays ripple free. Zinc is much easier to work with but kinks and creases much easier. Both are far superior to plastic if fitted well and are doable with thought and care. Plastic is very forgiving as it can be bent and twisted into place without distortion of the finished job.

Secret is to having good (and safe) access. Trying to do it on a ladder or pair of ladders is a pain and it usually ends up looking like a roller coaster. plastic is more forgiving as stainless and especially zinc can easily twist and crease.

Just think, we could soon have a “Hi everyone, I’m Poc-ster” 🤯

Hi and welcome, another Joe 90 … that’s me gonna get confuzzzled

Morning Sir, that’s a good attitude to life

It’s going from Bodge to worse 🤪

Hi and welcome

Now this is a difficult one, ethically the person/company causing the damage should take responsibility but as you are the employer then it’s technically you. are you paying day rates or contract price?

If the bitumen has dried up and started falling apart then you are better taking the lot off and re doing it. You will just end up with loads of wet insulation and a bigger headache

Do you have MVHR? If so then doors do need larger than normal gaps underneath. if not then yes the gap is excessive. Have the doors been cut while fitting or were the frames too high?

It would stop kids punching holes in plasterboard but very little else. If solid boarding isn’t needed for bracing then it’s a waste of time and money

This is just the sort of job that is easier to do than explain

Assuming you have no high side bits And the centre is your level and guide then a bed on these as if you were laying bricks and some good “dolops on the side bits to add stability, bed down to level and then afterwards go back and point the sides up

Okie dokie, good ole CT1 … every builders best friend

Just about any flexible material or filler will do, are you sure the noise is from the small gaps? More likely board movement acting like a sound board. Or transmission through the structure

Absolutely right, economy of scale! The bigger turbines are so much more efficient from production, infrastructure, output and maintenance wise. we supply a lot of access equipment for blade maintenance and it’s amazing how many are not producing due to poor placement and specification.

Many hill tops are not suited to wind turbines, or should I say not efficient anyway. If the wind direction is up the slope you can have eddy’s and vortices. wind turbines need steady, linear air flow acting evenly on the blades. Different wind speeds between bottom blade and top causes cyclic loads and they are noisy and cause premature blade failure. swirling wind, gusts, too low, too high all cause turbines to feather and shut down because they cannot react to the direction or speed effectively.

A lot of HVAC and dust extraction systems are poorly designed (if at all) and installed. filters can be too small or too large, air flows can be too low or too high. no use having a very fine filter with high air velocity as the small particles behave like bullets or shot blast material and destroy the filter as they hit it.
