THE REAL NUMBERS
The hidden costs of drafty windows are draining your bottom line
Drafty windows quietly cost you real money. Chilled tenants run space heaters; overheated tenants throw open windows in January. Summers send air-conditioning bills soaring. And every comfort complaint costs staff time — while unhappy tenants are the ones most likely to leave.
WexWindows™ solves these problems without the major expense and disruption of replacement — so you stop paying for problems you can’t see.
Space-heater & A/C spikes
Comfort ‘fixes’ tenants make themselves run up your energy and electrical costs.
Comfort complaints
Every “too hot / too cold” ticket costs staff time and goodwill to resolve.
Tenant turnover
Uncomfortable tenants move out — and re-leasing a unit is far costlier than keeping a paying tenant.
Wasted usable space
Perimeter floor area near cold or overheated windows goes unused — space you’re paying for but can’t rent comfortably.
WHY OWNERS CHOOSE WEXWINDOWS
Three ways WexWindows protect
your bottom line
Increase property value
Lower energy losses strengthen cash flow — which lifts your property’s value, refinancing options, and resale price.
Reduce hidden costs
Fewer drafts mean fewer space heaters, lower A/C loads, fewer complaints, and less costly tenant turnover.
Install & maintain with ease
Panels snap onto existing glass in minutes. Windows still open and close, and WexWindows™ are maintenance-free.
THE OWNER’S ADVANTAGE
Better cash flow today means better loan terms tomorrow
Lenders set your loan value by looking at cash flow. By cutting the energy losses that quietly erode cash flow, WexWindows™ strengthen your financial position — helping you secure better interest rates, more favorable terms, and a higher price when it’s time to sell.
It’s a building-envelope upgrade that pays back on the balance sheet, not just the utility bill.

QUESTIONS FROM OWNERS & MANAGERS
What you need to know
Will installation disrupt my tenants or building operations?
No. There’s no construction, no debris, and no tools required — panels snap onto the existing glass in about 5–6 minutes per window, so your team is up and running quickly with minimal disturbance.
Is financing available?
We can help connect you to financing options.
Do the windows still open and close?
Yes. WexWindows™ let your windows operate exactly as they always have, and they don’t impede emergency egress.
Is it code-compliant?
WexWindows™ are the first window insulation panel approved by the NYC Department of Buildings and are made from a Class A fire-rated, Greenguard®-certified material — helping with mandates like Local Law 97.
How does the cost compare to replacing windows?
WexWindows™ run roughly 20% of full window-replacement cost — delivering envelope savings without the major expense, disruption, and decades-long payback of replacement.
Are they maintenance-free?
Yes. Once installed, WexWindows™ are maintenance-free — there’s nothing for your staff to service or upkeep.
Can my project qualify for utility incentives?
Often, yes. WexWindows™ are approved for customer incentives by utilities such as Con Edison — we can help you confirm what’s available in your area.
