Technical Information 

The technical team at Wild Environments regularly reviews the latest materials and manufacturing technology at our workshop in Warwickshire. The result of this means that we continuously use the best possible designed components which we source locally wherever practicable. These components are sourced ensuring their environmentally friendly and sustainability characteristics. Wild Environments’ reputation has been built on quality, reliability and longevity and with the British climate being temperate but changeable, this will give you peace of mind.

Structure and installation 

The floor, roof and walls in all of Wild Environments’ garden rooms are fully insulated. You would think that these three important elements would be standard in buildings sold as garden rooms but be aware that it’s not always a feature with other manufacturers. The walls are multi layered (9 layers) which brings super high weathering and insulation properties. The roof and walls consist of a multi-layer construction system called SIPs (Structural Insulated Panels) which provides excellent thermal capabilities. These incredibly strong panels are made from of an energy efficient foam core, sandwiched between a high density OSB exterior. The OSB is responsible for the strength whilst the core accounts for its superior thermal performance. A useful bi product of the sealed construction of SIPs is a noticeable noise transfer reduction. SIP panels cleverly do not absorb moisture and therefore mould does not grow. We are so confident of the integrity of our garden buildings’ sturdy core structure that we include a 10-year structural guarantee with all of our garden rooms.

Double Glazing

As we use top quality insulation and membranes, it makes complete sense to use doors and windows of equal quality to those used in houses, for our garden rooms to ensure that the thermal efficiency is not wasted. We use A rated, energy efficient eco-friendly double-glazed doors and windows made from either UPVC or aluminium as standard.

Membranes

It’s crucial for the longevity of garden rooms to feature adequate membranes both on the exterior and interior of the building. Again, not all garden room manufacturers use both. Wild Environments uses DuPont Tyvek Housewrap between the OSB and the treated timber batons. This durable, lightweight and breathable membrane is made of high-density polyethylene fibres for long term protection against the elements. We use Protect VC Foil Ultra VCL and Air Barrier between the OSB and the service cavity on the interior side of the walls. This robust and highly effective, low emissivity, reflective vapour control layer is used to enhance the performance of the wall and ceiling construction.

Electrics

We include electric sockets and LED lighting with its own distribution board as standard, all fitted by our fully qualified electricians.

Durable Exterior

We want your garden room to give you decades of enjoyment and be as low on maintenance as possible. One way we do this is by using an EPDM rubber membrane on the roof exterior which has its own 20-year guarantee with a life expectancy of 50 years. We also have several finish options including environmentally friendly composite cladding and sustainably sourced timber cladding. You will find more detail about our finish options here but in summary, composite cladding is made from a unique blend of recycled wood and plastic, creating a strong and durable material with excellent performance benefits. The plastic content means that the boards are resistant to rot, damp and insects. It also never needs to be sealed, stained or painted and the boards won’t warp or crack. We obtain all of our premium grade natural timber from FSC (Forest Stewardship Council) or PEFC (Programme for the Endorsement of Forest Certification) assured sources.
