Clever Design

The clever and unique part of our design is that a foam filled uPVC profile sits between the wood and aluminium profiles to give the wood extra protection from the elements. The uPVC profile is substantial in size which gives great insulation and protection to the wood. The uPVC profile adds space between the aluminium and wood which creates a cold barrier. This is critical for aluclad doors.

Solid Hardwood

Natural solid hardwoods will enhance any home interior. Our products are quality approved, low maintenance and designed to last. The new AluClad door system from Costello Windows ticks all these boxes and more. Our new AluCLad windows and doors American White Oak for the interior. Oak adds a feeling of quality, strength and beauty to any home.


Quality Materials

On the inside you get the wonderful warm texture and atmosphere of wood, while on the outside the low maintenance protective features and longevity of aluminium. The wood on the inside of the frame offers a natural thermal break resulting in outstanding heat loss resistance and energy efficiency. Aluclad doors are great for commercial builds and new build homes. Aluminium clad timber doors are naturally very solid and well insulated window with low U-Values. The aluminium finish offers a high weather resistant factor. Double doors and single glass doors are the styles available. Colours too are limitless, just give us the RAL code that is required. Our new AluCLad doors use the very best American White Oak for the interior. Oak adds a feeling of quality, strength and beauty to any home. American White Oak is a solid hardwood, which gives great strength.
