White Upvc Door Flat Infill Panel MDF Reinforced 28mm or 24mm Thick Heavy Duty UV Stable 

These are extra large sized heavy duty UV stable door flat panels used by our own installation teams since 1983 to glaze Upvc residential doors for both security and thermal installation. The panel is easily cut to size using a fine cut timber panel saw, Jig saw, or if preferred a circular saw. 

Something to Note:

These door panels use 1.4mm skins unlike most other cheaper door panels which are approximately 75% thinner at only 0.8mm thick. Thinner skins become more brittle at lower temperatures, making them less robust for everyday use.

  • Colour: White 
  • Size option 1: Width: 900mm, height 1050mm
  • Size option 2: Width: 900mm, height 2100mm 
  • 28mm thick or 24mm thick options (see below for more information about size tolerances)
  • Reinforced with 4mm MDF Sandwiched between foam thermal infill

Note that these door panels work to a 1mm-3mm tolerance (size increase) on either side in regards to the thickness dimensions. However, the thickness dimension will never be less that what size is purchased. This means that sometimes the panel can be slightly thicker than expected but the foam infill easily compresses to the desired size. This allows for a more snug fit meaning that it will be secure when installed and not loose.

If the foam infill is only on one side of the MDF then it is the 20mm panel. If the foam infill is on both sides of the MDF in equal amounts then it is the 24mm panel. If the foam infill is on both sides of the MDF with more on one side than the other, then it is the 28mm panel. Please see the photographs for a visual reference.

Fitting Tip: Upvc door panels are not difficult to replace with only a few basic skills required:

Measure the glazing panel or glass to be replaced noting the width and height. Measure the top, bottom and middle (doing this ensures you do not get the wrong size as once you have cut it there is no going back).

If you do not have an existing panel or glass to work to then you need to measure the glazing area to be filled and allow an approximate 5mm fresh air gap all round to be able to slide the panel into. The Upvc will expand and move in hot weather so do not make it so tight it cannot move as this will increase the chance of the panel bowing cracking and delaminating.

Transfer the dimensions onto the panel to be cut & in the case of panels with a raised molding ensure these are centrally laid out to fit in the overall dimensions. N:B leave the protective film on the panel for marking out & cutting to prevent any marks or scratches.

Tip: The panels always come with a clear protection tape adhered to both sides to stop them been marked. When you fit the panel just pull the tape back by about 30-40mm from all four sides in and out so that you do not trap the tape behind the gaskets when glazing up.

The panel is easily cut to size using a fine cut timber panel saw, Jig saw or if preferred circular saw. 

Removing the beads is best done with a purpose made glazing bead knife (Our part:2143 & you may find our how to do You Tube Video: Replacing A Double Glazed Unit (DGU).

Once cut to size offer the panel into the glazing area ensuring it is sat on the purpose made glazing packers that were there previously (noting the tips in the how to do video) and re-fit the glazing beads you earlier removed ensuring they go back in the same place and order you removed them.

Remember due to the bonding process of door panels they will always work to a 1-2mm depth tolerance. In doors that are particularly old it should be noted that the glazing gaskets will have lost some compression purely due to been compressed over such a long time and variation in seasons. If this is the issue you may need to also consider replacing the glazing gaskets as an option. Alternatively a suitable all weather sealant may be additionally required. 

Clean the panel and door down using either warm soapy water or Upvc cream cleaner for more stubborn marks and scuffs. Never clean with chemicals or abrasive materials.
