Insulation

Insulation is one of the most important factors for year-round comfort in any prefabricated timber building – whether a garden room, outdoor office, or residential cabin. Wall, roof, and floor insulation, combined with double-glazed windows and doors, work together to create a genuinely warm, dry, and quiet building in all seasons.

Benefits of high-quality insulation

• Year-round use: An insulated building is comfortable to use in any Irish month – not just the summer.

• Lower energy costs: Timber naturally retains heat; insulation dramatically reduces the energy required to maintain a comfortable temperature.

• Moisture protection: Proper insulation reduces condensation, preventing mould, decay, discolouration, and structural damage – particularly important in Ireland's damp climate.

• Protection for stored belongings: Maintains optimal temperature conditions in garages, workshops, and storage buildings.

How insulation works

Insulation material is placed between the layers of the wall, roof, or floor construction. The three insulated construction types in our range are:

• Single log wall with vertical cladding and insulation in the air gap

• Twin skin double log wall with insulation in the cavity

• SIPs (Structural Insulated Panels) – insulation integrated within the structural panel

Insulation specifications

Basic insulation

25 mm PIR insulation in walls, roof, and floor. Suitable for seasonal use – summer houses, holiday cabins, and buildings used primarily in the warmer months. Reduces overheating in summer and lowers heating energy requirements in winter.

Advanced insulation (BRF – Building Regulation Friendly)

120 mm PIR walls, 175 mm PIR roof, 200 mm PIR floor. Fully compliant with residential building thermal insulation requirements. Provides year-round comfort, maximum energy efficiency, excellent noise insulation, and minimum indoor moisture levels. Recommended for all buildings intended for permanent or intensive daily year-round use in Ireland.

Component insulation

• Wall insulation: Boards fitted between wall layers with an air gap for ventilation. 25 mm PIR (basic) or 120 mm PIR (advanced).

• Roof insulation: Fitted between roof boards and covering material. 25 mm PIR (basic) or 175 mm PIR (advanced).

• Floor insulation: Fitted beneath floorboards between joists. 25 mm PIR (basic) or 200 mm PIR (advanced).

• Windows and doors: Double-glazed as standard. PVC recommended for the highest thermal and acoustic performance and longest service life.

Mobile home insulation

Our mobile-home-classified granny annexes are insulated with 100 mm PIR for walls, roof, and floor – significantly thicker than the basic specification – ensuring all-year residential comfort.

SIPs insulation

• Walls: 100 mm EPS insulation

• Floor: 50 mm XPS insulation

• Roof: 150 mm EPS insulation

PVC windows and doors are included in the price for all SIPs models.

What is included in the price

• Log construction with basic insulation: insulation material plus double-glazed windows and doors.

• SIPs construction: insulation, EPDM roof coating, breathable membrane, and 9 mm OSB sheets.

• Advanced insulation (BRF): insulation material plus PVC windows and doors.
