Benefits and Technology Applied

Insulation and Energy Efficiency

Choosing the 62 mm insulated wall version delivers near‑140 mm timber equivalent insulation. The low U‑value (~0.69 W/m² K) dramatically reduces heat loss, making the Terminator cabin suitable even in winter climates. All‑year usability becomes practical and cost‑effective, especially when combined with double glazing and proper base insulation.

Build Quality and Security

Interlocking tongue‑and‑groove logs resist warping and improve weather tightness. Doors and windows come with multi‑point locking, stainless steel friction stays, and toughened glass—delivering both robustness and safety. The structure includes forced ventilation and storm braces to handle wind loading and moisture control.

Delivery and Assembly Technology

Dunster House uses its own delivery fleet for direct drop to your site—typical delivery to driveway within mainland UK, free for orders over £200 (B&Q, Dunster House). Although assembly is DIY‑oriented, real‑world user reports note that building takes 3–4 days or more depending on help, weather, base condition and complexity .
