Fantastic Reasons to Buy the Outpost Insulated Building

1. Fully Insulated: EcoQuilt Insulation

Wood is known for its natural insulating properties, which helps in preventing the transfer of heat between the interior of a garden building and the external environment. EcoQuilt insulation ensures that the heat from the interior of the insulation structure remains when the external temperature dips.

What’s good about this is that the entire building is insulated; from the roof and walls to floor. Meaning, this insulated building will only ever require minimal heating. In most cases, it won’t require any additional heating at all. The less heating you use, the more you can save money on energy consumption.

Insulation key features:

  • Non toxic and non irritant
  • CFG and HCFC Free – Requires no special clothing or equipment

2. The Ideal Outdoor Entertainment Room

With the Outpost Insulated Building, you can create your own entertainment room, personal gym, garden office or even a garden pub. With countless options to choose from, you’ll never run out of ways to make use of this versatile building throughout the year!

3. Modern Pent Design

With its modern pent design and double glazed double door and windows, easy access to the building is ensured, making it ideal for entertaining. In addition to the double door design, the Outpost also has a plain rear and under 2.5mm ridge quality.

Double glazing features on both doors and windows, giving your building 360° insulation. The Outpost also has 7ft Internal eaves height from front to back.

4. Tear Resistant Felt

To protect the roof from harsh weather conditions and water damage, the Outpost features high performing waterproof felt which gives the overall building structure the ultimate roof protection.

This unit offers green mineral felt as a roof covering option. This felt is durable and watertight, which helps in preventing any water from getting through and damaging the roof.

In addition, the felt is more durable than traditional sand felt, meaning that it doesn’t need to be regularly replaced, making it a long term, cost-effective option.

5. Durable Tongue & Groove

The boards interlock to create 66mm thick, durable panel construction, offering high-quality weather protection. 

Not only that, but with the 11mm T&G Cladding, 27mm x 44mm framing, and ECOQuilt Expert Foil Insulation, you’ll be assured of unbeatable quality. Without them, your outdoor structure would struggle to withstand some of the UK’s harsher weather conditions.

The multi-foil insulation locks the heat in with the same U-Values as 120mm Glass Wool Insulation. What’s more, the tongue and groove cladding provides a premium aesthetic and structural durability in equal measure.

Note: This unit is complete with 11mm Tongue and Groove roof, floor and green mineral felt roof covering.

6. Optional Pressure Treatment

Maintenance is vital in ensuring your insulated building remains in excellent condition all year round. When it comes to upkeep for your garden building, pressure treatment represents a brilliant way to improve longevity, weather resistance and resistance against mould, damp and rotting wood.

Pressure treatment works by submerging the wood into a liquid preservative in a vacuum. This seeps into the wood and provides it with a much greater level of resistance to rot or fungal decay.

The finished product is an undoubtedly rewarding one. We recommend opting for pressure treatment, as this is a process which is usually carried out by professionals, so isn’t something you can do yourself.

As a way of protecting the BillyOh Outpost Insulated Building from the elements, you can choose to opt for pressure treatment. Opting for this particular upgrade will ensure your garden building remains looking great during the summer and winter alike, irrespective of weather conditions.
