ProVia doors feature factory-installed Q-Lon weatherstripping that seals against cold air infiltration. Professional installation eliminates the gaps that cause most winter drafts.
Steps to a Draft-Free Door:
- Professional Weatherstripping: Q-Lon weatherstripping along the top and sides interlocks with a Q-Lon corner seal. This system outperforms DIY adhesive strips.
- Proper Frame Alignment: A door that doesn’t sit square in its frame creates gaps. Our installers shim and adjust every frame for a tight seal.
- Threshold Seal Inspection: The bottom sweep and threshold work together at floor level. Worn sweeps are a top source of energy loss.
- Glass Panel Insulation: ComfortTech Warm Edge Glazing reduces heat loss through decorative glass. Condensation drops with this built-in thermal barrier.
- Reducing Air Infiltration: Reduced air infiltration in a home cuts heating oil consumption by 15% per Energy Star data. A sealed door plays a direct role.
- Annual Maintenance Tips: Check your door’s weatherstripping and threshold sweep each October. Clean sliding patio door tracks before the first frost.
Protecting Your Home From Winter Drafts:
- Top Recommendation: Replace aging doors with a new ProVia entry door for complete factory-sealed protection.
- Best for Quick Fixes: Ask about weatherstripping replacement during your free consultation.
- Best for Sliding Doors: Soft-Lite patio doors with integrated seals.
