Spectrum are extremely happy with the results and their service users are thrilled to have an outdoor space they can use. This highly insulated SIP built turnkey Box is perfect for the quiet space it was intended for, creating a versatile year round secure warm room with a 60 year life span. The sliding Rational Alu Clad door and windows combine with the SIPS to create a high level of insulation and airtightness as well as a great level of acoustic insulation. A small foot print mean this is an ideal size for a garden and works well as office space too.
