Do you know your Door Construction Types?

Solid doors are the ideal for finish and noise, however there are some restrictions on cutting them down which leads to the use of block doors.

Frequently there is some confusion as to why there are 2 types of solid doors, and where to use them. So we’ve explained it all for you here with comparison to the hollow core door.


Hollowcore / Honeycomb Core

Honeycomb core flush doors are manufactured with a high density cellular core. This ensures the door is structurally stable while remaining a light weight and functional option for your home.

This cost-effective option is incredibly versatile, available in bi-fold and multi-fold options, as well as being made to order in a vast range of sizes. When it comes to selecting the face material you have the internal options of commercial primecoat, light commercial primecoat, primecoat MDF or SPM, whilst the external doors are available in Tempered Hardboard, A’Bond Paint Ply or SPM.


Solicore (SCX1)

Solicore doors are designed to minimise noise, while still remaining functional. These products have a particle board core which not only absorbs sound but is also highly moisture resistant. Solicore doors are a great option for homes in any area, but are also a perfect fit for commercial applications such as schools and hospitals.

Solicore doors have a range of face material options including Primecoat MDF, Tempered Hardboard, A’bond Paint Ply, SPM or Tassie Oak.

Best for high gloss finishes and can be made to order for special sizes with a lead time of approximately 10 days.


Blockboard/Solid Core (STPC)

Flexible and versatile, solid blockboard doors can be cut to any size. A quick and easy solution to those tricky and uneven doorways.

These doors can also be cut to any size to suit your application.

They are not recommended for semi or high gloss paints due to the potential of ‘showthrough’.

Due to open-ended core plate, all surfaces must be sealed otherwise your warranty will be VOID.
