Mercia Shiplap Sentry Box

Make the most of your garden space by adding a stylish, practical, and high-quality garden building from Mercia Garden Products. The Mercia Tall Stores offers great storage potential. The tall roof and spacious interior make this range the ideal storage unit for sports equipment and larger garden items. Constructed using 12mm shiplap cladding, 10mm solid sheet board floor, 8mm solid sheet board roof, and 28x28mm framing for strength and durability.

Pressure treatment is a high-pressure chemical process designed to preserve exposed timber, by providing optimal protection against insect attack, fungal attack, and decay. The pressure treatment process impregnates preservative chemicals deep into the timber fibers to protect it against the elements and help to prolong its life. The whole process takes several weeks, to ensure the timber is fully dried and the chemicals are fully permeated.

What are the benefits?

  • Higher quality and more durable.
  • Garden buildings that are fully protected against rot, fungal decay, and insect attack.
  • 15 years anti-rot guarantee as standard.
  • Attractive bronze color, highlighting the warmth and charm of the timber.

The durable, robust nature of our Champion Workshops is further enhanced by the free pressure treatment that is applied across the range. Preservative is been forced into the timber at high pressure, increasing longevity and removing the need for annual re-treatment. The improved longevity is reflected by a brilliant 15-year guarantee against rot and fungal decay.
