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.

1d3b4a13dab4435d9c93936f30940c6eAs experienced tradesmen will tell you, insulated cavity closers are the economical way to close cavities around window and door openings when you’re building.

TBS is pleased to offer you Dacatie Insulated Cavity Closers, from Quantum Profile Systems. As a market leader, the Dacatie brand gives you the assurance that you’ll be complying fully with building regulations.

Dacatie Insulated Cavity Closers are made of reconstituted PVCu and include insulation which is CFC free and zero rated for Ozone Depletion Potential (ODP). They offer a highly versatile solution in first fix installation when a frame former is not required.

The closers come in 2.4m lengths. The SF-Multi is good for cavities 50 – 100mm. The TF-Multi (at our Towcester branch only) is good for cavities 100 – 150mm.

These beauties reduce the risk of condensation, mould and moisture migration across the cavity.

They overcome variations in cavity width.

And you don’t need any ties – simply nail them to the blocks.


Metal Stud Partitions and How to Install Them

January 27, 2017


Are you considering a partition in your home? Or doing an interior fit-out where you’ll need interior walls? You really have two options: a timber stud wall or a metal stud wall (sometimes called stud and track).

The timber option is economical, certainly, but there are definite drawbacks. Timber may not be straight, it can shrink or split, and the final structure isn’t especially robust. This may be fine in certain applications, but not in others.

A metal stud wall uses metal components that are straight and true. Timbers can slot easily and securely into the C-shaped grooves. The result is an altogether more solid structure.

compound-member-of-stud-and-trackThe stud and track system uses U channels for the horizontals of your frame, and C studs for the verticals. You’ll need a spirit level, some tin snips and a powered screwdriver.

Here’s a video of how it’s done: How to Install Metal Stud Framing.

For the infill, you can use wood-based panels, like plywood or OSB sterlingboard. There is plenty of debate over the ethics of plywood these days, as it is usually sourced from overseas and potentially from endangered rainforests. OSB is made of resin-treated wood strands, so it has the added advantage of being a uniform product with no interior holes or weaknesses. You can screw into it anywhere with complete confidence.

Once your frame is up, you have the option of insulation, then a facing with plasterboard. Job done! And TBS stocks all these products, so we can help you with the entire project.
