‘Palight’ brand foamed Pvc

Foamed Pvc is an extremely versatile sheet plastic. Of all the different brands I’ve tried over the years Palight has proved to be by far the easiest to work with by hand. In fact it’s become my own first choice as the basis for almost everything I make! It can be easily cut with a scalpel, or carved, sanded, even embossed to a certain extent. It can be painted without any danger of warping (though it will usually require priming first) is not affected by humidity or (within reason) heat from strong lights. It is also incredibly light. For example, when I use it to make larger-scale sets for stop motion animation it delivers the structural strength of MDF at a fraction of the weight! The only caveat in all this is the fact that it can only be glued with superglue, but on the other hand this gives a very strong bond and also once one has mastered the option of ‘gluing from outside’ it all becomes much easier!

Palight (together with its ‘economy’ version Palfoam, which may even be slightly softer still, though I hardly notice the difference when working with them) is manufactured by the global plastics company Palram in a range of thicknesses from 1mm to 19mm. I normally only ever use the matte white but 3mm and 5mm Palight is also available in ‘matte’ black and a small range of matte and gloss colours.

I’ve chosen and illustrated three examples of its use: firstly using 1mm Pvc (the thinnest available) for intricate forms; secondly using 2mm Pvc for general construction; thirdly using Pvc as one may not otherwise have expected, to create surface effects.

Although it’s much easier to draw on foamed Pvc with a pencil (unlike styrene or ABS) I prefer to work out a design on paper and spraymount a copy on the plastic. In the photo below I have started cutting out the ironwork shape through the paper. Curves are much easier with Pvc than cardboard because the composition is much smoother, with no particles or fibres to affect the passage of the blade. Cutting is easier also because it is more porous (foamed) on the inside and will ‘give’ a little under the blade causing much less friction.

If the paper cutting template is lightly fixed with spraymount (especially the repositionable type) it can be easily peeled off the form once cut.

In this case the Pvc cut-out serves as a firm, cleanly cut basis upon which more detail, profiling or strengthening can be added on top. It’s a constructional principle of ‘building in layers’ which I’ve developed for myself over the years and try to follow most of the time. Below I’m adding a strip of styrene (a harder plastic which can be bought in a wide variety of pre-made strip formats) to make a thicker top rail. The easiest way to glue this on in exactly the right place first time is to position a guide-block (in this case a metal block) against the top, press the cut length of styrene against it and run a little thin superglue (using a plastic gluing brush or cocktail stick if preferred) along the join. The thin type of superglue will travel into the join and set immediately.

Below, I am doing similar but this time with a very thin (c. 1mm) cut strip of the same Pvc to give the arches more substance. Pvc is nicely bendable, especially in thin strips. The trick with bonding a strip in an exact curve is to fix the strip with a spot of glue at one end first, then curve and position the rest, spot-gluing at intervals to the other end. Ive cut the strip a little longer, to be trimmed off when the end is reached.

The following example illustrates some of the benefits of using foamed Pvc to construct walls etc. Even thin Pvc will retain its rigidity well. For example 1mm Pvc can be used to represent walls up to 30cm high easily, as long as theyre not load-bearing. Because Pvc sands well cut edges can be cleaned up if uneven and right-angles bettered prior to gluing together. Also because Pvc sands well the visible joins after gluing can also be sanded often to invisibility!

In the next example I am constructing a piece of vaulted ceiling by first making a framework box (2mm Pvc) and then curving a thinner piece of Pvc underneath it. Curves are much easier to cut smoothly in Pvc because there is no grain and the material ‘gives’ a little. It is also possible to make a definite guiding groove in the soft surface using a compass fitted with two metal points. Curves can also be perfected by sanding them.

Here I have scored the 1mm on one side to help it to bend. The same can be done by heating it uniformally and securing it until cool on a curved surface such as a bottle. The piece can be glued in position, in much the same way as the curved profiles on the ironwork example, by first securing one end, pressing the rest into position and ‘spot gluing’ from outside. Here the end has been made purposely longer and can be easily trimmed off once the rest is glued.

Whereas other plastics such as styrene or ABS can be sanded to modify the surface, because foamed Pvc ‘gives’ so much more it can be inscribed or even embossed to create different textures. Here is just one example where I have scraped the surface with coarse sandpaper to simulate wood.

To build up the structure of wood panelling I first cut out the raised areas as continuous pieces, then pressed firmly with sandpaper (120 grit, mounted on a small block) along the length of each part. ‘Grain follows length’ almost always for any realistic wood construction.

I scraped those areas of the base piece which would remain visible as panels then stuck the frames into position (just spacing dots of superglue). I used different thicknesses of ‘half-round’ profile styrene (also sanded) inside the panels and around the door frame.

The painting method and the choice of medium are fairly crucial in making this technique work. Normally it wouldn’t  be reasonable to paint plastic with any water-based paint  and expect it to stay, but because the surface is sanded it can grip quite well. The paint needs to emphasize the scratches made by the sandpaper, settling well in the grooves but not too much on the surface. Sometimes this can be achieved well with washes of thin paint, other times by rubbing in/rubbing off like a polish. For this example I just used a regular ‘System3’ yellow ochre acrylic thinned down with a little water and ‘rubbed into’ the plastic surface using a medium-hard brush. It takes some practise to find out for oneself what a particular painting medium might do and how best to do it.

Where to get it in the UK and abroad

For a thorough list of sources in the UK and a comparison of current prices see my page Updated sources/prices of specific materials which you will find in the Suppliers section.

If you just want to try it out or if you don’t need much, the best options are either the small sheets of 1mm or 2mm stocked by 4D modelshop or the packs of small sheets from Acrylic Online (though these are only 3mm or 5mm). If you’re happy with a 1220x2440mm minimum sheet size Bay Plastics offers by far the best range for the best prices.

In theory there shouldn’t be a problem obtaining Palight wherever you are in the world because the manufacturer Palram is a global company which appears to have an extensive network.


The information pages for Palight and Palfoam on this website include the most comprehensive and reliable technical info for these materials, including a ‘Fabrication Guide’ and recommended adhesives.

Australia and New Zealand may be fairly well served by Mulford Plastics .. thanks to Nicola Gredziuk for this information. She writes that they stock a range of matte and gloss types from 1-15mm thickness. For example a full sheet of matte white (the type I generally use) costs $46 and a sheet of matte black 3mm $76, with delivery around $40. There is a blanket cutting-fee of $15 if you want the large sheet cut into more manageable sizes. These prices compare fairly well with those generally in the UK, though not quite as good as Bay Plastics.

  1. Hi David,

    Thanks for sharing so much information, your blog is great! I designing a front-opening miniatures shop (1:12 scale). Would I be able to securely attach hinges to Palight to support the weight of the front facade? If so, what is the minimum thickness you would suggest?

    • Hi Kristen,

      I think you could but they would have to be bolted through rather than just screws, the Palight would be too soft. I’m guessing the absolute minimum would be 5mm but better the next one up if dimensions are over 50cm.

  2. Hello, David,
    I am a fan of both this site and your book Model-Making: Materials and Methods. Many thanks for all of the inspiration and the treasury of genius advice! I’m a painter but now branching out to making a scale model (from which I will later paint). The model is 1:6 scale, and I found, like you, that Palight is the perfect base construction material (I’m using 12mm which is perfect wall width). I would like to construct the walls of the room so that the model can be broken down for storage; so rather than using Super Glue, I would like to join them in a removable way. May I please ask if you have any suggestions for how I might join the walls in a way that can be taken apart? Thank you!

  3. Hi David –
    Great stuff. So helpful. Thank you.

    If you’re still checking this, I do have a question about the 11th image down on this lesson. You mention “I used different thicknesses of ‘half-round’ profile styrene (also sanded)”. Are you sanding those to be round, or does the palight come in rounded strips? I’m in the states and haven’t been able to find anything like that.

    Thanks and Best Regards,

    • Hi Tony, No? You’re kidding! What I was using comes from evergreenscalemodels.com .. an American firm! But it’s styrene as I said, not PVC, not Palight .. so maybe that’s what’s gone wrong here. We can find it in UK from a couple of manufacturers apart from Evergreen .. I think we’re spoilt here in a way, for such a little island! best, David

  4. I don’t know if this thread is still active…..Thanks for all the info supplied it’s really helpful. I have one question which is how do you glue palight from the outside with superglue please.

  5. Hi David,
    I recently discovered your site and am thrilled to find so much information here. I’m in Australia and thought perhaps this might help others who only need small quantities – Bunnings stock Suntuf Handi-Art foamed PVC sheets 1200x600x3mm for AU$21 it is made by Palram Australia P/L. They also have 6mm, but both white. I’m using it to make a 1:6 scale diorama.
    Keep the info rolling, you’re a star!

    • Thanks for the info! That’s going to be really helpful! I had always thought, because Palram is such a big global supplier, that Palight would be available just about everywhere .. but that’s not the case at all! I’m doing workshops in Austria later and there there’s only 2mm white (Palfoam) and at about 5X the price it is here!

  6. Hi! I’m a scene design student in the USA and I’ve recently this blog and it has been unbelievably helpful! Thank you so much!

    I’m very curious about using palight but I can’t for the life of me seem to find a place in North America that sells palight in 1mm size. I found one kind of another brand but it came in such bad condition that I can’t even use it. If you have any places you know of I’d be really grateful.

    Thank you for such an amazing resource. It’s done wonders for me and my class!

    • Call the Palram factory in Pennsylvania (1-610-285-9918) and they can give you some names of places in the US that sell their products. Then you can call around and find which has the product you want. The 1 mm Palight is harder to find, but some Plastics sellers do carry it. You may have to buy a large sheet, but then you will have it and can share with colleagues. It’s as much fun as David describes.

  7. I can’t believe I’ve only just found this. I’ve been using foamex for a couple of years now and extolling it’s virtues (I thought I was original) – but you have taken it to the top level – nice stuff!

    • Hello Lee,

      Thanks! Foamed Pvc been used for quite a while in architectural model-making .. but it’s still rare that people from other disciplines know about it .. so you can still keep the ‘original’! You refer to ‘foamex’ .. can I ask which brand you use and where you get it? Have you tried Palight?

  8. hello and congratulations.
    are the frame and the base 3mm thick palight?
    thanks for answer I’m learning for my doll house.

  9. Fantastic site David, thanks for sharing your wealth of knowledge!
    I’m a designer for theatre in Vancouver, Canada. I’m very interested in using Palite, but I’m having trouble finding a supplier near me, or who will ship small quantities. However, I can get Sintra. Have you ever used that brand?
    Thanks again!

    • No I haven’t heard of that one. I thought the usual ones in the US and Canada were ‘Foamex’ or ‘Forex’ but this might have changed. In any case when I used these brands years ago they seemed a bit tougher and brittle, although still cut-able with a scalpel.
