A warm foundation is not just a structural element — it is a strategic engineering solution that impacts comfort, heating costs, durability, and property value.
SUN LOFT designs and delivers energy-efficient foundation systems, taking into account:
Site geology
Architectural design
Climate conditions
Tailored Foundation Solution
in One Consultation
We analyze:
Soil conditions and groundwater level
Budget and timeline
Site topography
Architectural loads
01
2–3 optimal solutions
02
Understanding of operating costs
03
Estimated project cost
04
Construction timeline recommendations
We apply three main types of energy-efficient foundations, allowing us to select the optimal solution based on your site, budget, and architecture.
Smart Foundation Solutions for Any Site
Insulated Swedish Slab (USS)
The standard for flat sites
What is it?
A monolithic insulated slab made of high-strength concrete and extruded polystyrene (XPS), with an integrated water-based underfloor heating system and all инженерные коммуникации built inside the structure.
All engineering systems are fully integrated into the structure
Up to 40–60% reduction in heating costs due to elimination of thermal bridges
High construction speed — walls can be built immediately after slab installation
Perfectly level surface ready for final flooring
Integrated heating system for the ground floor
Flat plots and clients who want a fully engineered base with high energy efficiency and a ready-to-finish floor.

Ideal for:
Reinforced Insulated Slab
An enhanced evolution of slab systems
What is it?
An advanced version of the insulated slab technology with additional stiffening ribs along the perimeter and in key load zones. This creates a monolithic structure that combines the advantages of slab foundations with the stability of strip foundations.
Minimal deformation risks due to monolithic structural behavior
High stability on complex and frost-prone soils
Increased load-bearing capacity for heavier structures
All advantages of USS: energy efficiency, integrated utilities, built-in heating
Sites with unstable or frost-susceptible soils, and for houses with increased structural loads.

Insulated Finnish Foundation
What is it?
An insulated slab supported by a system of insulated piles or columns that compensate for elevation differences.
A ventilated space is created between the ground and the structure.
Ventilated subfloor space that prevents moisture and dampness
Easy access for maintenance of engineering systems
Underfloor heating system for the ground floor
An efficient solution for sites with complex terrain
Plots with a moderate slope where a warm and serviceable crawl space is required.

Basement Foundation
What is it?
A fully insulated basement level designed in accordance with modern standards of energy efficiency and comfort.
Increased property market value
Efficient use of complex terrain
Ability to accommodate a gym, boiler room, or relaxation area
Increased living space without expanding the building footprint
Plots with a pronounced slope or when there is a need to increase the usable area of the house.

Ideal for:
Comparison with Strip Foundation
Lower performance on weak soils
Longer construction time
Higher maintenance requirements
Drainage complexity
Risk of freezing
Higher costs
A strip foundation remains a common solution. However, in modern energy-efficient homes, it has a number of limitations
Foundation as a Long-Term Investment
annual heating savings
20-30%
repair and insulation costs
Reduced
