Energy-Efficient Window Replacement
Laholm • Triple-glazed windows key-in-hand installation with finishing trims
In this project, we replaced 12 old double-glazed wood windows with modern energy-efficient triple-glazed wood windows (3-glasfönster) on a private villa in Laholm. The homeowner's main objective was to reduce winter heating bills and improve acoustics.
Heat Loss Challenges
The old wooden frames had weathered and warped, leaving drafty gaps. A thermal camera inspection revealed massive heat losses around the window perimeters. It was also critical to match the traditional architectural aesthetic of the villa.
Solutions & Steps
Our carpenters performed a full removal and installation cycle:
- Careful removal of old windows and trims without damaging wall structures.
- Prep and leveling of window openings, applying wood preservative.
- Installing new Swedish-made high-performance wood windows (aluminum clad exterior).
- Applying vapor-permeable and windproof insulation tape according to Swedish code.
- Installing metal sills and caulking joints.
- Fitting new interior and exterior trim casings and sill boards.
- Hardware calibration and final walkthrough with the client.
Project Results
The window replacement delivered immediate comfort improvements:
- Energy savings: Window heat loss dropped by 75%, yielding roughly 25% savings on monthly heating bills.
- Comfort: Drafts are completely gone; the home is now warm, silent, and draft-free.
- Aesthetics: New windows perfectly blend into the classic facade, giving it a refreshed look.
- Durability: Aluminum-clad frames require zero repainting and last over 30 years.
FAQ about Window Replacement in Laholm
What is the best season to replace windows?
Windows can be replaced year-round, including winter. For cold-season installs, each opening is exposed for just 15–20 minutes, preventing the house from cooling down.
What does U-value mean for windows?
U-value measures the rate of heat transfer. The lower the U-value, the better the window insulates. Modern triple-glazed units have U-values below 1.0.
Can I use the ROT tax deduction for window installation?
Yes, labor costs for window replacement qualify for a 30% ROT deduction deducted directly from your invoice.
