Insulated Garage Door Installation & Weather Sealing

Heated attached garages and home workshops require an unbroken thermal boundary. We install multi-layer sandwich panels featuring high-density polyurethane insulation and perimeter weather seals.

OVERVIEW

Protecting Your Building Envelope Against Nordic Cold

In Finnish winters, an uninsulated garage door acts as a massive thermal radiator, draining expensive heating from adjacent living rooms, home workshops, or basement levels.

Our insulated door installation focuses on double-skin sandwich panels filled with high-density polyurethane foam, combined with thermal breaks between inner and outer steel skins. This eliminates cold bridging and prevents interior condensation and frost accumulation.

SPECIFICATIONS

Thermal Architecture & Sound Dampening

Polyurethane Sandwich Core

Injected high-density PU foam completely bonds to inner and outer steel skins for structural stiffness and thermal retention.

Thermal Break Frame Seals

Integrated polyamide thermal breaks stop outdoor freezing temperatures from transferring through the steel jamb framework.

Dual-Lip Perimeter Weather-strips

Flexible side and top rubber gaskets maintain airtight contact with the door face even during high crosswinds.

Acoustic Street Sound Dampening

Dense composite sandwich construction significantly dampens vehicular traffic and neighborhood noise.

SCOPE OF WORK

What’s Included in Insulated Door Installation

  • Rough Opening Thermal Inspection: Checking lintel insulation depth, frame sealing, and floor threshold flatness.
  • Multi-Layer Insulated Panel Stack: 40mm–45mm PU-core panel assembly with interlocking weather-tongue joints.
  • Heavy EPDM Bottom Bulb Gasket: Compressible frost-resistant threshold seal conforming to slight concrete floor undulations.
  • Top Header Draft Flap: Continuous rubber seal preventing air leakage along the upper lintel portal line.
  • Draft Audit & Compression Check: Verifying even seal compression along all four sides of the door portal.
QUESTIONS & ANSWERS

Insulated Door FAQs

An insulated door prevents heat loss and blocks freezing drafts. In an attached unheated garage, it helps retain ambient heat transferred from the home, keeping indoor temperatures significantly milder than outdoor freezing conditions.

A panel thickness of 40mm to 45mm with a continuous polyurethane core is the standard recommendation for residential heated and semi-heated garages throughout the Nordic region.

No. Torsion counterbalance springs are calculated and calibrated to match the exact panel weight, allowing the door to be lifted effortlessly with one hand when operated manually.
