How to fit panels and trims

Fitting our panels is extremely straightforward. Seasoned DIYers will have no trouble. If you're not as confident in your DIY skills, then any good plumber, fitter, joiner, decorator etc. will find few problems with installing our cladding.

The best way to attach IPSL wall panels is to use adhesive. We recommend Polyurethane Adhesive or something similarly high-grab for best results. Cover the subwall (i.e. the wall that you'll be attaching to - 'subwall' literally meaning 'wall under', so the subwall refers to the wall that will be under the panels when fitted) entirely with adhesive. This complete coverage generally works out to use two 310ml tubes for an area of about 8' (2440mm) x 4' (1220mm). Then, once the area you wish to cover to is entirely clad with adhesive, put the panels in place. DON'T use a contact adhesive as you'll need some manoeuverability!

It may be that you need to join your wall panels together along the same wall, i.e. the wall you wish to cover is wider than an individual panel, so you'll need to use more than one panel to cover the full wall. This isn't a problem. To ensure waterproofing, we can supply a 'H' section joint trim. It's called an 'H' joint because the trim, when looked at from the ends, looks like a capital letter H.

This will provide you with a more waterproof solution than simply using silicone sealant. You may wish to run a very fine bead of silicone in the groove of the trim, so as to stick the panel and trim together inside once fitted, but as our trims are made to match our panels, and the panel will be stuck fast with adhesive and held in place to the wall, this isn't necessary (and using too much silicone will make it bleed out when you push the panels in place).

However, for some of our panels, you wouldn't need joint trims at all. These panels come as Tongue-and-Groove (hereafter 'T&G') panels, i.e. they will slot together when placed next to one another, as there is a tongue section on the one end, and a groove section on the other.

We also supply a 'J' edge trim (again, so-called because of its physical resemblance to the capital letter J) for capping the edges of the panels. This is ideal for covering over the edges of the panels, be these along the top (especially necessary if you're not running the panels all the way up to the ceiling) or the sides of the panel. For instance, you'll probably need to cut the panels to size so you'll have some exposed ends which will need to be covered over to be made completely waterproof. Again, you might want to run a small bead of silicone here.

Above: some of our different kinds of 1-part 'J' edge trim, and a diagram showing how the 2-part trim fits onto the panels.

The other kind of wall panel trim we do is a corner trim. We can do trims for both internal corners (i.e. where there's a corner on the inside of an angle, usually a ninety-degree angle) and external (the opposite, usually 270 degrees). These are fixed in very much the same way and are a far superior waterproof choice than simply using sealant.

All our ceiling panels are T&G panels. Instead of using adhesive, the best way to fix our ceiling panels would be to use screws. The best way to do this would be to screw into the groove section of the panel. Then, when you come to slot the next panel into place, the tongue section will cover up the groove section of the previous panel, thus hiding all the screw heads, so that all will be visible will be the decorative side of the panels.

When it comes to the sides of your ceiling panels, you can either use edge trim (in the same manner as described above) or ceiling coving (image shown below) which would provide you with a more attractive finish.

Please bear in mind that, because all our trims are made to specifically match our different panels, then the trims you may be using won't look like the ones shown in this guide. For example, our narrow Proclad panels would be suited to that narrow two-part H-trim displayed above, but our thicker 10mm panels would use their own, wider H-trim.

That just about covers the basics of fitting our panels and trims. If you have any further questions, please feel free to get in touch!
