Condensation Problems? Ventilation or Dry Lining Could Be Your Answer

If you live in an older house with solid walls, you may well have a problem with damp appearing on your interior walls. This is almost certainly caused by condensation. There are things you can do about this, and TBS can help you.

First, check that your home is properly ventilated. One very practical answer is to fit extractor fans. TBS stocks axial fans and centrifugal fans from Manrose, some with a built-in humidistat, together with a range of grilles and ducting that should meet your requirements, .

Another thing to consider is dry lining the walls. It’s a bigger job but can make a serious difference. Click here for an overview of what’s involved – very handy if you’re considering the DIY option.

Batten frame with insulation being added

Dry lining involves fitting battens to the walls, adding insulation, then fixing a plasterboard wall. The frame can be made using 25 x 38mm battens. Insulation could be either 25mm polystyrene or Knauf Dritherm cavity wall insulating batts.

Now you have two options. Either tack a polythene vapour barrier to the battens, then fix 9.5mm plasterboard. Or you can opt for Knauf Vapourshield plasterboard, which is already backed with silver foil.

TBS stocks all the products you would require for dry lining. So call our Sales team at any TBS depot for information, advice and some good prices.


Part J Regulations for You: Hidden Gas Flues Need Access Panels

June 9, 2017


Ever since Part J Regulations came into force in January 2013, access panels have become a vital part of the heating engineer’s stock in trade.

  • Any gas boiler system with a hidden flue MUST have an access panel
  • Access panels should allow visual inspection within 1.5m of any joint or bend
  • Any existing acoustic or fire rating must be maintained
  • A carbon monoxide alarm with a long-term power source must be fitted 1 – 3m from the boiler

If any of these conditions are not met, the Gas Safe engineer is obliged to mark the boiler ‘at risk’ and instruct that it be switched off until access panels are fitted.


TBS stocks a range of access panels, from Select Products. Ideal for when you need to provide access to a fixture behind a ceiling or a stud wall – or create access where it was forgotten!

The standard panels are made of heavy duty plastic. We can offer you the following sizes:

105 x 158 mm at £9.98

162 x 238mm at £12.48

300 x 300 mm at £18.73

Should you be working to specific fire regulations, we now stock a 300 x 300mm panel that is 1 hour fired rated, at £56.08.

This link (though using a different make) shows you how to fit an access panel into a ceiling.PFFD
